Technical Field

The present invention relates to a radiographic imaging apparatus and a radiographic imaging system.

Background

In medical practice, radiographic images are generally captured using a radiographic system. In the radiographic imaging, there are cases where imaging fails due to factors such as a positioning error of a patient, a body movement or insufficient inspiration of the patient, an error in setting of imaging conditions, or detection of foreign matter (referred to as imaging error).

The imaging engineer confirms the radiographic image obtained by imaging, and thereby determines an imaging error. When the imaging engineer determines that the imaging is not correct, the radiographer performs imaging again to acquire a radiographic image necessary for diagnosis. Even if the imaging engineer does not determine that the imaging error has occurred, the doctor may determine that the radiographic image is unsuitable for examination.

In this way, in the determination of the imaging error, when the criterion of the imaging error by the imaging engineer is different from the criterion of the imaging error by the doctor who performs diagnosis using the radiographic image, for example, the amount of time and labor required for re-imaging and re-examination are increased, and the radiographic image that does not need to be the imaging error is set as the imaging error, and thus the re-imaging is unnecessary originally, and there is a possibility that problems such as inconvenience may occur from the viewpoint of exposure to radiation.

Therefore, by determining an imaging error with a predetermined reference, unnecessary imaging errors can be reduced, and re-inspection after the end of inspection and the like can be reduced. As a result, it is expected that the work efficiency in medical facilities will be improved, and unnecessary exposure or reexamination will be reduced for the subject.

Regarding the determination of imaging errors based on predetermined criteria, there is disclosed a downward radiography system: in a specific radiographic system, regression analysis is performed to detect image degradation due to positional variation (patent document 1). Further, with respect to the improvement of the work efficiency of the recheck, there is disclosed the following imaging control apparatus: in the divided photographing, re-photographing can be performed without resetting photographing conditions (patent document 2).

Disclosure of Invention

Technical problem to be solved by the invention

If it is determined that there is an imaging error, the imaging is performed again after that, but there is still a possibility that the imaging error will occur even during the re-imaging. If the imaging error occurs in the reimaging, the reimaging is repeated again, which is not preferable in terms of an increase in the number of examinations and an increase in exposure to radiation. Therefore, it is desirable to suppress the occurrence of an imaging error during re-imaging in addition to the determination of the imaging error on a predetermined basis.

Detailed Description

As shown in fig. 1, an X-ray imaging system 10 (radiographic apparatus) that uses X-rays as radiation includes an X-ray generation apparatus (radiation generation apparatus) 11 and an X-ray imaging apparatus 12. The X-ray generation device 11 is composed of an X-ray source (radiation source) 13 and a source control device 14. The radiation source generates radiation. The X-ray imaging apparatus 12 is composed of an X-ray detection panel (radiographic unit) 15 and a console 16.

The X-ray imaging system 10 is further provided with an irradiation switch for instructing the start of irradiation of radiation, a standing imaging table for imaging the object Obj in a standing posture, a lying imaging table for imaging the object Obj in a lying posture, and the like. Fig. 1 shows a case where the subject Obj stands at a position opposed to the X-ray source 13 in an imaging room in which the X-ray imaging system 10 is installed and the subject Obj is imaged in a standing posture.

The X-ray imaging system 10 includes, for example, an imaging error management device that manages information to be imaged. The X-ray imaging System is connected to an image server such as a PACS (Picture Archiving and Communication System) for managing X-ray images taken and Information related to the X-ray images, and an Information management server such as an HIS (Hospital Information System) or an RIS (Radiology Information System) for registering and managing Information such as patient Information, medical Information, examination Information, accounting Information, and imaging commands for each patient.

The X-ray source 13 incorporates an X-ray tube that generates X-rays Ra, an irradiation field limiter that limits an irradiation field that is an area irradiated with the X-rays Ra, and an irradiation field display light source that emits irradiation field display light indicating the irradiation field. In order to confirm the position of the object Obj, etc., an optical camera may be mounted in the X-ray source 13.

The radiation source control device 14 includes a touch panel, a voltage generation unit, a control unit, and an irradiation switch. The touch panel is operated while setting the irradiation conditions of the X-ray Ra and the size of the irradiation opening of the irradiation field limiter, the irradiation conditions being composed of the tube voltage applied to the X-ray tube, the tube current, and the irradiation time of the X-ray Ra.

The voltage generating section generates a tube voltage to be applied to the X-ray tube. The control unit controls the operation of the voltage generating unit to control the tube voltage, the tube current, and the irradiation time of the X-ray Ra. The control unit has a timer for starting the time measurement when the X-ray Ra is generated from the X-ray tube, and stops the operation of the X-ray tube when the time measured by the timer reaches the irradiation time set under the irradiation conditions. The control unit operates the irradiation field limiter and sets the size of the irradiation opening to a size set by the touch panel.

When the irradiation of the X-ray Ra is started, an operator such as a radiography engineer who is a user of the X-ray radiography apparatus operates the irradiation switch. The irradiation switch is a two-gear pressing type. When the irradiation switch is pressed to the 1 st position (half-pressed), the control unit starts a preparatory operation until X-rays Ra are generated in the X-ray tube. When the irradiation switch is pressed to the 2 nd position (full-press), the control unit generates X-rays Ra in the X-ray tube. Thereby, the X-ray Ra is irradiated toward the imaging region of the object Obj.

The X-ray detection panel 15 detects, for each pixel, an X-ray Ra irradiated from the X-ray source 13 and transmitted through the object Obj, and sets the X-ray Ra as an X-ray image 30. The X-ray detection panel 15 has a wireless communication unit and a battery, and operates wirelessly. The X-ray detection panel 15 wirelessly transmits the X-ray image 30 to the console 16. The X-ray detection panel 15 may communicate with each other by wire.

The console 16 is configured by installing a control program such as an operating system and various application programs on a computer such as a notebook personal computer. The console 16 includes a display 17 and an input device 18 such as a touch panel and a keyboard. The display 17 displays a radiographic image obtained by imaging. The console 16 displays various operation screens having operation functions based on a GUI (Graphical User Interface) on the display 17, and receives various operation instructions from the operator via the input device 18 via the various operation screens.

The console 16 receives an input of a photographing command 21 shown in fig. 2. The imaging command 21 is information for instructing an operator to perform X-ray imaging from an imaging requester such as a doctor in a medical department, for example. The photographing command 21 is transmitted from the RIS to the console 16, for example.

The photographing command 21 has items such as a command ID (Identification Data), an object ID, and a photographing method. The command ID is a mark or a number for identifying each photographing command 21 and is automatically given by the RIS. The object ID of the object Obj to be photographed is described in the object ID item. The object ID is a symbol or a number for identifying each object Obj.

The imaging technique is information on the imaging part of the object Obj and the posture and orientation of the imaging part. The photographing part includes knee, head, cervical vertebra, chest, abdomen, hand, finger or elbow, etc. The posture is a standing posture, a lying posture, a sitting posture or the like of the object Obj, and the orientation is the orientation of the object Obj such as the front, the side or the back with respect to the X-ray source 13. Although not shown, the photographing command 21 includes, in addition to these items, items of subject information such as the name, sex, age, height, and weight of the subject Obj. The imaging order 21 also includes items such as the medical department to which the imaging requester belongs, the ID of the imaging requester, the date and time when the imaging order 21 was received via the RIS, the post-operation periodic observation, the effect determination of the therapeutic agent, and the like, and notification items to the operator by the imaging requester.

The console 16 stores therein a menu/condition table 22 shown in fig. 3. The menu/condition table 22 associates a shooting menu for specifying a shooting technique in which a shooting part, a posture, and an orientation are grouped with an irradiation condition corresponding to the shooting menu. The set of the shooting menu and the irradiation condition includes not only a default registered item but also an item which the operator edits or is newly added separately from the default set. The shooting menu may be a shooting menu that defines only the shooting region, not the shooting technique.

The console 16 displays a shooting order list listing the contents of the shooting orders 21 shown in fig. 2 on the display 17 by the operation of the operator. The operator checks the shooting command list to confirm the contents of the shooting command 21. Next, the console 16 displays the contents of the menu/condition table 22 shown in fig. 3 on the display 17 so that a shooting menu can be set. The operator selects and sets a shooting menu corresponding to the shooting method designated by the shooting command 21.

The console 16 wirelessly transmits a condition setting signal including various information such as an imaging menu set by an operator, an irradiation condition corresponding to the set imaging menu, a command ID, and a console ID for identifying a symbol or a number of the console to the X-ray detection panel 15.

After setting the imaging conditions, the operator positions the X-ray source 13, the X-ray detection panel 15, and the object Obj at desired positions, and then drives the X-ray source 13 to irradiate the object Obj with the X-rays Ra. The X-ray Ra transmitted through the object Obj is irradiated to the X-ray detection panel 15, whereby the X-ray image 30 is detected by the X-ray detection panel 15.

As shown in fig. 4, the X-ray detection panel 15 transmits the X-ray image 30 to the console 16. The console 16 displays the X-ray image 30 on the display 17, thereby showing it to the operator. In fig. 4, the imaging part in the X-ray image 30 is a knee.

The console 16 sets the X-ray image 30 into an image file 31 in a format conforming to, for example, the DICOM (Digital Imaging and Communication in Medicine) standard as shown in fig. 5, and transmits it to the PACS.

The image file 31 is a file in which the X-ray image 30 and the accompanying information 32 are associated with each other by one image ID. The incidental information 32 includes object information, a command ID, a shooting menu, an irradiation condition, and the like. The imaging requester can view the X-ray image 30 through the client terminal by accessing the PACS with the client terminal and downloading the image file 31.

In fig. 6, the console 16 includes a storage device 41, a memory 42, a CPU (Central Processing Unit) 43, and a communication Unit 44 in addition to the display 17 and the input device 18. Which are connected to each other via a data bus 45.

The storage device 41 is a hard disk drive built in the console 16 or connected via a cable or a network, or a hard disk array having a plurality of hard disk drives connected in series. The storage device 41 stores a control program such as an operating system, various application programs, various data attached to these programs, and the like.

The memory 42 is a work memory for the CPU43 to execute processing. The CPU43 loads the program stored in the storage device 41 into the memory 42 and executes processing in accordance with the program, thereby collectively controlling the respective sections of the console 16. The communication unit 44 has a function of communicating with other devices or networks, and is responsible for communicating various data such as the X-ray image 30 with the X-ray detection panel 15.

In fig. 7, an operation program 51 and an imaging error reason database (hereinafter, abbreviated as db (database))52 are stored in the storage device 41. The reason for the shooting error DB52 will be described later. Although not shown, the menu/condition table 22 shown in fig. 3 is also stored in the storage device 41.

When the operation program 51 is started, the CPU43 functions as the image acquisition unit 61, the image processing unit 62, the display instruction receiving unit 63, the display control unit 64, and the like in conjunction with the memory 42 and the like. Therefore, the X-ray imaging apparatus 12 includes an image acquisition unit 61, an image processing unit 62, a display instruction receiving unit 63, and a display control unit 64. The image acquisition unit 61 acquires an image such as the X-ray image 30 received by the communication unit 44 for analysis. Generally, the image acquisition section 61 acquires all the X-ray images 30 obtained by imaging, and sends them to the image processing section 62, respectively.

As shown in fig. 8, the image processing unit 62 includes an imaging error determination unit 71, an imaging error reason determination unit 73a, and a correction information determination unit 74. The imaging error determination unit 71 includes a learned model 72a and a determination image adjustment unit 72 b. The image processing unit 62 analyzes the X-ray image 30 transmitted from the image acquisition unit 61. The analysis is performed for the purpose of determining whether or not the image capturing has failed and specifying information on the reason for the image capturing failure, which is the reason for determining that the image capturing has failed. Therefore, the image processing unit 62 analyzes the X-ray image 30, thereby setting the radiation image determined to have failed to be imaged as an imaging error, and specifies the reason for the determination, that is, the reason for the imaging error and correction information for eliminating the reason for the imaging error.

The image processing unit 62 learns the X-ray images acquired in the past in advance, and determines the X-ray image 30 using the learned model 72a for determining whether or not the imaging of the X-ray image 30 has failed. By this determination, information on whether or not the shooting has failed and information on the reason for the shooting failure are output.

By using the learned model 72a, the determination can be made based on a predetermined criterion. Further, the determination result can be obtained in a short time. The learned model 72a can use, for example, an algorithm or a library that is good for the determination result of the image processing. Further, an algorithm or a library that is good for the determination result of the X-ray image may be constructed and used. In addition, as the learning data, data in which at least information on whether or not an imaging error is present in an X-ray image acquired in the past is used. In addition, data in which any one of imaging data, patient data, and the like, which is incidental information related to the X-ray image, is added to the X-ray image may be used. Further, data in which the feature amount is selected according to the type of the X-ray image and the feature amount information is given to the X-ray image may be used.

If the determination can be made based on a predetermined criterion, other known machine learning techniques or image processing techniques other than the machine learning technique may be used in addition to the learned model 72 a. Further, a plurality of image processing techniques other than the learned model 72a and the machine learning technique may be used, and preferred techniques may be used in different ways depending on the type of the part or the like of the X-ray image 30, the accuracy of the determination result, and the like.

The determination criterion is set in advance. For example, the reference is strictly or loosely set according to the purpose of the X-ray image 30. More specifically, for example, when determining whether the X-ray image 30 is successfully captured with respect to the imaging menu, a threshold value is set in advance for a deviation of the drawing of the portion that becomes the gist, and the threshold value is further decreased, whereby the criterion can be set strictly, while the threshold value is further increased, whereby the criterion can be set loosely. Therefore, a desired determination criterion can be set by the medical institution. Further, even in the same medical institution, the determination criterion may be set differently for each clinical department such as emergency department, medical department, or surgery, or for each imaging area, training purpose for the operator to determine the imaging error, or the like, or for each purpose, even in the same medical institution.

The setting of the determination criterion may be changed. The setting can be changed by the input device 18 or the like. The image processing unit 62 may change the setting by feeding back an instruction or the like from the operator from a display instruction receiving unit 63, an approval receiving unit 81, or the like, which will be described later. A setting unit (not shown) provided in the image processing unit 62 sets a determination criterion or changes the setting of the determination criterion. The setting unit has a function of performing various settings related to the image processing unit 62.

In addition, since the learned model 72a determines whether the X-ray image 30 has failed to be captured, it is possible to distinguish between an image that has failed to be captured and an image that has not failed to be captured. Therefore, determination that photographing has not failed, that is, determination that photographing has succeeded can be made.

The determination image adjusting unit 72b adjusts the X-ray image 30 before the determination. The adjustment is performed for the purpose of improving the accuracy of the determination. Therefore, the content of the adjustment includes, for example, cropping in which a part of the image is selected as a region to be determined in the X-ray image 30, deletion of an unnecessary region in the image, and adjustment of brightness, saturation, and the like. In particular, when the learned model 72a using deep learning or the like is used, there may be a case where an accurate analysis result cannot be obtained due to erroneous classification or the like of an image region irrelevant to determination in the X-ray image 30, and it is preferable to avoid such a case. Therefore, in adjusting the X-ray image 30, it is preferable to perform trimming of a region to be determined in the image designated by an operator or the like in advance, thereby more accurately analyzing the region to be determined. In addition, adjustment may not be performed.

As shown in fig. 9, when the adjustment by the cropping is performed, the adjustment is performed by selecting the region to be determined using the frame 85 in the X-ray image 30 displayed on the display 17. The frame 85 is, for example, a rectangular frame, and may be set to include an area automatically determined by an image recognition technique, or may be set by an operator dragging the area designation cursor 86 on the X-ray image 30 to adjust the size of the frame 85, that is, the area to be determined on the X-ray image 30. The determination image adjusting unit 72b can perform the imaging error determination of the knee joint as shown in fig. 9, for example, with higher accuracy by performing the trimming-based adjustment of the region selected and determined using the frame 85 on the X-ray image 30.

The reason for imaging error determination unit 73a determines the reason for imaging error based on the information output by the learned model 72a during determination. The imaging error reason determination unit 73a includes a deviation amount measurement unit 73 b. The information that the learned model 72a outputs during the determination is information related to the cause of the determination that the learned model 72a has determined that the imaging has failed. Examples of such items include an error in positioning of the patient, a body movement or a lack of inhalation of the patient, an error in setting of imaging conditions, and detection of a foreign object such as a warmer or a necklace.

The reason for the imaging error may include information on an item other than the information on the reason for determining that imaging has failed. For example, the reason for the imaging error includes an item in which the patient has a positioning error and information about which position is deviated to which extent. The deviation amount measuring unit 73b outputs information on the deviated portion and the deviation amount based on the information output from the learned model 72b and the image analysis technique of the X-ray image 30 determined as the imaging error. The reason for the shooting error may include descriptions of a failed part and a non-failed part. Therefore, the reason for the shooting error may include information on the portion determined to have failed shooting and information on the portion determined to have succeeded shooting. For example, in the case of a positioning error of a patient, a detailed reason for an imaging error may be considered, such as an accurate knee flexion angle in the height direction of the patient but insufficient internal rotation of the knee.

The correction information is information indicating a recommendation for reducing the number of times of re-photographing. Therefore, the correction information is information indicating a suggestion that the shooting is successful by shooting again (preferably once). The correction information is the same part corresponding to the X-ray image 30 that is a failure in imaging and the past X-ray image of the imaging data, and is information comparing the sample image when the imaging was successful and the X-ray image 30 that is a failure in imaging. As described above, the shooting failure reason and/or the correction information contains a recommendation for reducing the number of times of re-shooting.

The correction information determination unit 74 accesses the shooting-error-reason DB52 to determine correction information for eliminating the shooting error reason determined by the shooting-error-reason determination unit 73 a. The imaging error reason DB52 is a database that stores the imaging error reason in association with correction information for the imaging error reason. For example, more specifically, the imaging error reason DB52 includes an imaging error reason/correction information table 52 a.

The reason for imaging error/correction information table 52a associates the reason for imaging error with correction information for the reason for imaging error. For example, in the case of a knee joint side image in which the imaging menu is "knee/flexion posture/side" (see fig. 5), the successfully imaged X-ray image 30a is "the joint surfaces of the medial and lateral condyles of the femur substantially match" or the like (the shao chuang article, "new and easy X-ray photography" 2 nd edition, jinyuan publishing co., 2012, p 137). Therefore, when the articular surfaces of the medial and lateral condyles of the femur do not match, the reason for the imaging error is determined based on the shape and the size of the deviation. Then, in order to correct the deviation to a desired position and perform imaging, it is preferable to use correction information such as how much the object Obj is tilted.

The reason for the imaging error and the correction information table 52a will be described in detail. As shown in fig. 10, when the X-ray image 30b in which the medial femoral condyle 75b and the lateral condyle 75a do not coincide with each other is obtained, the image processing unit 62 analyzes the X-ray image 30b to recognize, for example, that the distance between the contour of the medial femoral condyle 75b and the contour of the lateral condyle 75a exceeds a predetermined threshold value, based on the contour of the medial femoral condyle 75b and the contour of the lateral condyle 75 a. Therefore, the image processing unit 62 sets the X-ray image 30b as an imaging error that is a failure in imaging the knee joint side image. In addition, in the successfully captured X-ray image 30a, the contour of the medial femoral condyle 75b coincides with the contour of the lateral condyle 75 a. The reason for the imaging error is determined to be "the deviation between the medial and lateral condyle edges is considered to be large" based on the positions of the contour of the femoral medial condyle 75b and the contour of the lateral condyle 75a, and the like. ". From the imaging error reason/correction information table 52a, the correction reason for the imaging error reason is "may be slightly more preferred to be pronation. ". Thus, the reason for the imaging error and the reason for the correction of the X-ray image 30 are determined.

When the correction information is displayed, the operator can take a picture again while viewing the correction information. For example, in the re-imaging of the X-ray image 30b, the following advice is displayed with respect to the inclination of the thigh with respect to the irradiation surface of the X-ray Ra: the imaging is successful without changing the direction of the body to be slightly inclined, for example, by about 10 degrees, with respect to the direction of the irradiation surface of the X-ray Ra.

More specifically, the correction information may be any information other than text, such as still images, moving images, illustrations, icons, moving images, and the like, as long as the information can indicate that the operator has a suggestion for successful re-imaging during re-imaging. When using still images, moving images, illustrations, icons, or animation images, the correction information preferably includes the following images: the X-ray image 30 that has been shot in error is a sample image obtained when the shooting has been successful and is a past X-ray image of the same portion and/or the same imaging data. Further, the sample image may be processed to display a portion to be changed.

The correction information may include the X-ray image 30b that has been shot erroneously. Further, information combining these items may be used. More specifically, for example, the X-ray image 30b is an image in which a partial region of the object Obj is superimposed with an arrow indicating a partial position, a tilt direction, or the like of the object Obj. Further, the X-ray image 30b that has been shot erroneously and the X-ray image 30a that has been shot successfully may be arranged. Alternatively, in the case of animation or moving images, for example, animation in the following manner is possible: based on the image of the object Obj on the X-ray image 30b that has failed to be captured and the image of the object Obj on the X-ray image 30a that has succeeded in being captured, the line that has deviated on the X-ray image 30b that has failed to be captured is moved slowly so as to coincide with the corresponding line on the X-ray image 30a that has succeeded in being captured.

As shown in fig. 11, for example, when the X-ray image 30 is displayed on the display 17, the deviation amount display 87 is displayed in a superimposed manner, whereby information based on the position where the deviation is present and the deviation amount of the deviation measuring unit 73b is output. The deviation amount display 87 numerically displays the deviation amount of the portion where the deviation amount is largest among the portions where the deviation is present, and the deviation amount is expressed by a numerical value of "5 mm" or the like, and the portion where the numerical value is measured is expressed by an arrow or the like. Thus, the operator can more accurately recognize the degree of pronation at which successful imaging can be performed. The offset display 87 may be set so as not to be displayed in some cases.

The display control unit 64 performs control to display the determined correction information on the display 17. The operator checks the correction information displayed on the display 17 of the console 16 and then performs shooting again, thereby reducing the possibility of shooting error again.

As described above, since the X-ray imaging system 10 determines an imaging error with a predetermined criterion and suggests a proposal for reducing the number of times of re-imaging, unnecessary imaging errors can be reduced, and re-examination after the end of examination and the like can be reduced.

In addition, when the X-ray image 30 is an imaging error based on the analysis result of the image processing unit 62, the operator can be notified of the imaging error. The notification method may be any method as long as it can notify the operator of the fact that the imaging error is generated, and a display, a sound, or another notification method may be used. After the imaging, the operator usually confirms the X-ray image 30 displayed on the display 17, and therefore, a notification method of displaying using the display 17 is preferable. For example, when the X-ray image 30 is an imaging error, the display control unit 64 displays a notification icon or the like on the display 17 to notify that the image is the X-ray image 30b of the imaging error.

The display method displayed on the display 17 may be any method as long as the operator can understand that the X-ray image 30b is made a shooting error. For example, to change the color of the screen of the display 17, display a notification icon for an alarm, or always display the notification icon in the display 17 and change the display of the notification icon. When confirming the captured X-ray image 30 after the capturing, the operator is notified that the captured X-ray image 30 is determined to be a capturing error based on the analysis result of the image processing unit 62 by looking at the display 17.

Further, since it takes time for the operator to analyze, it is not clear whether the operator has failed to make an image capture error because the operator is analyzing the image capture error or has determined that the image capture has succeeded.

Therefore, in the analysis, information about the time required for the analysis can be displayed in the display 17. For example, a time bar or the like may be displayed in the display 17 so that whether the analysis is in progress or the analysis has ended can be discriminated by the display.

As shown in fig. 12, the display instruction receiving unit 63 includes a correction information display instruction receiving unit 76 and an imaging error reason display instruction receiving unit 77. The display instruction receiving unit 63 receives an instruction as to whether or not to display the correction information or the reason for the imaging error on the display 17, that is, a correction information display instruction or an imaging error reason display instruction, and instructs the display control unit 64 to display the correction information or the reason for the imaging error.

The correction information display instruction receiving unit 76 receives a correction information display instruction as to whether or not to display the correction information on the display 17. For example, the inspection engineer may make corrective information display instructions via the input device 18. When the X-ray image 30 is determined to be out of order, whether or not to display correction information can be performed in accordance with the correction information display instruction.

Therefore, for example, in combination with the notification that the X-ray image 30 captured is an imaging error, the operator determines the imaging error of the X-ray image 30 after the notification, and instructs the display of correction information and displays the correction information. Thus, compared to the case where the correction information is displayed without an instruction, the operator needs to confirm the X-ray image 30 and then determine whether or not the correction information is displayed, and thus, it is possible to prevent the imaging error determination of the X-ray image 30 from being entrusted to the imaging error determination by the image processing unit 62, and to prevent the chance of reducing the correction related to the imaging error determination when the imaging error determination by the image processing unit 62 is inappropriate.

Similarly, the imaging error reason display instruction receiving unit 77 receives an imaging error reason display instruction indicating whether or not to display the imaging error reason on the display 17. An operator such as an inspection engineer displays a reason for the shooting error through the input device 18. When the X-ray image 30 is determined to be an imaging error, whether or not to display the reason for the imaging error can be instructed in accordance with the reason for the imaging error. Therefore, similarly to the case of the correction information display instruction, it is prevented that the imaging error determination of the X-ray image 30 is only requested to the imaging error determination by the image processing unit 62 or that the opportunity of correction related to the imaging error determination is reduced when the imaging error determination by the image processing unit 62 is inappropriate.

More specifically, the correction information display instruction or the imaging error reason display instruction is performed by a simple method such as key input, click, or icon touch using the keyboard, mouse, or touch panel display 17 as the input device 18.

The display control unit 64 has a display control function of controlling the display 17 to display the correction information or the reason for the imaging error in accordance with the instructions from the correction information display instruction receiving unit 76 and the imaging error reason display instruction receiving unit 77 of the display instruction receiving unit 63. The correction information display instruction or the photographing error reason display instruction can be given every time of photographing, and the instruction can be continued until the next setting by one setting.

The display instruction receiving unit 63 is configured as described above, and therefore, for example, may be configured as follows: the notification icon is always displayed on the display 17, and when the operator does not determine whether or not the X-ray image 30 is shot, the operator clicks the notification icon to give an instruction to display correction information or an instruction to display a reason for a shooting error, thereby displaying the correction information or the reason for the shooting error.

In this way, when it is assumed that the image capturing is not successful, the reason for the image capturing failure and/or the correction information are not automatically displayed, but an operation for displaying an instruction by the operator is required, and thus, for example, when the operator considers that the image capturing is successful, unnecessary display is not performed on the display 17, and thus, the operation of confirming the X-ray image 30 is not hindered. Even in cases other than the case where the operator has shown a suggestion of re-imaging when the operator has determined that the X-ray image is an imaging error, for example, when the operator is unsure of whether or not the operator has determined that the X-ray image is an imaging error, the operator can correct the criterion of the operator to a predetermined criterion by giving an instruction to display correction information obtained by analysis by the X-ray imaging apparatus 12 and/or the reason for the imaging error, and can confidently determine the imaging error of the X-ray image 30. Further, since the operator can confirm the determination of the imaging error by the X-ray imaging device 12, when there is a problem in the criterion of the determination of the imaging error by the X-ray imaging device 12 or when the determination of the imaging error is erroneous, it is possible to prevent the situation where the operator does not actually make a determination of the imaging error in person with respect to the X-ray image 30, and the determination by the X-ray imaging device 12 is used as it is as the determination by the operator.

As shown in fig. 13, the X-ray imaging apparatus 12 includes a confirmation receiving unit 81. When the X-ray image 30 is set to be an imaging error, the acceptance receiving unit 81 receives whether the operator accepts the imaging error. The operator approves via the input device 18. When the approval receiving unit 81 receives approval, the approval receiving unit 81 receives the X-ray image 30 and necessary information from the image processing unit 62, and transmits the information to the communication unit 44, whereby the information is transmitted to each unit and the like. These pieces of information include a photographing command, an image file 31, and the like.

As a format of approval, for example, a display 17 displays a approval icon and a non-approval icon, and when the operator approves the determination of the imaging error by the X-ray imaging apparatus 12, the operator clicks the approval icon. In addition, the following includes a touch in a click. On the other hand, when the determination of the shooting mistake is not approved, the non-approval icon is clicked (refer to fig. 19).

When the approval icon is clicked, this indicates that the operator has determined that the X-ray image 30 that has been determined to have been shot by the X-ray imaging apparatus 12 as a shot error. Therefore, when the approval reception unit 81 receives the approval of the operator, the same processing as that in the case where the normal imaging error occurs is performed.

As shown in fig. 14, for example, when the X-ray imaging system 10 including the X-ray imaging apparatus 12 includes the RIS79 that manages imaging commands, the approval receiving unit 81 receives approval of an imaging error, and a command for re-imaging is registered in the RIS 79. The contents of the re-imaging command are acquired based on the information of the approved imaging command for the X-ray image 30 or the information of the image file 31 containing the X-ray image 30.

When the X-ray imaging system 10 including the X-ray imaging apparatus 12 is connected to the PACS78 that stores the radiographic image and the information related to the radiographic image, the approval receiving unit 81 receives the approval from the operator, and thus acquires the information from the RIS79 as the case may be, and transmits the X-ray image 30 and the information related to the X-ray image 30 to the PACS 78. More specifically, the image file 31 containing the X-ray image 30 is automatically registered in the PACS 78. The image file 31 is registered in the PACS78 in accordance with the DICOM standard so that information relating to a shooting error is input through the radiography system 10.

When the X-ray imaging system 10 including the X-ray imaging device 12 includes an imaging error management device (not shown) that manages the X-ray image 30b determined to be an imaging error, the acceptance receiving unit 81 receives acceptance of the imaging error of the X-ray image 30, and transmits the X-ray image 30b and information including the reason for the imaging error of the X-ray image 30b to the imaging error management device.

In addition, the following method is also possible: when the judgment of the shooting error is approved, the reason for the shooting error and/or the correction information is displayed on the display 17, and when the operator approves all the matters, the approval icon is clicked. For example, when the operator recognizes that the X-ray image 30 is an imaging error, but does not recognize the reason for the imaging error and/or the correction information, the operator clicks the non-recognition icon. Thus, the following method is also possible: the operator can correct the reason for the shooting error and/or correct the part of the information to be corrected. When the correction is completed, information approved by the operator can be sent to each section of the RIS and/or PACS by clicking the approval icon.

When the X-ray imaging apparatus 12 does not recognize the X-ray image 30b as an imaging error itself, the non-recognition icon is clicked. This allows the operator to change the situation itself in which the image capture error is assumed. In this case, the operator enters a reason for changing the determination by the X-ray imaging apparatus 12. The reason for this can be used to correct the criterion for the image processing unit 62 to determine an imaging error.

When the operator turns the X-ray image 30, which has been made a shooting error by the image processing unit 62, to non-approved by clicking the non-approved icon, the operator is a screen for selecting and editing whether to cancel the shooting error, change the reason for the shooting error, or change the correction information, as described above. When the shooting error is cancelled, the X-ray image 30 and information relating to the X-ray image 30 are transmitted to the PACS as an image whose shooting was successful. More specifically, an image file 31 containing an X-ray image 30 is automatically registered in the PACS.

In this way, the operator can automatically perform the operation and procedure when the operator determines that the image capturing is erroneous by a simple operation such as clicking of the confirmation icon. Therefore, the efficiency of the service can be improved. When the X-ray image 30 is finally determined to be either an imaging error or not, the signal ends the imaging of one imaging command.

Next, an operation based on the above-described configuration will be described with reference to a flowchart of fig. 15. First, the operator confirms the contents of the photographing command 21 in the display 17, and sets a desired photographing menu corresponding to the photographing command 21 via the input device 18. Thus, the set imaging menu and a condition setting signal including the irradiation condition and the like corresponding thereto are transmitted from the console 16 to the X-ray detection panel 15. After setting the imaging menu, the operator sets the same irradiation conditions as those corresponding to the set imaging menu in the radiation source controller 14 via the touch panel. Then, the operator starts the relative positioning of the X-ray source 13, the X-ray detection panel 15, and the object Obj.

For example, when the imaging menu is the imaging of the knee joint side image of "knee/flexion posture/side", the operator places the object Obj, i.e., the knee, on the bed 83 so as to be perpendicular to the X-ray source 13 as shown in fig. 16. The X-ray detection panel 15 is provided at a position facing the X-ray source. At this time, the operator sets the size of the irradiation opening of the irradiation field limiter, that is, the irradiation field, to the radiation source control device 14 via the touch panel. The operator operates the irradiation field display light source to irradiate the irradiation field display light to the electronic cassette. The operator takes the irradiation field display light as a guide and finely adjusts the positions of the X-ray source 13, the X-ray detection panel 15, and the object Obj so that the positional relationship therebetween is a desired relationship.

After the positioning, the operator operates the irradiation switch to generate the X-rays Ra from the X-ray source 13. The X-ray Ra irradiated from the X-ray source 13 and transmitted through the object is irradiated to the front surface of the X-ray detection panel 15. In the X-ray detection panel 15, the start of irradiation of the X-ray Ra is detected by the irradiation start detection function. Thereby, an irradiation start detection signal is wirelessly transmitted from the X-ray detection panel 15 to the console 16. After the start of irradiation for detecting the X-ray Ra, the X-ray detection panel 15 performs a pixel charge accumulation operation and an image reading operation to detect the X-ray image 30. The X-ray image 30 is wirelessly transmitted from the X-ray detection panel 15 to the console 16.

When the X-ray image 30 taken is wirelessly transmitted to the console 16, as shown in fig. 17, the X-ray image 30 and the notification icon 91 are displayed on the management screen 90 of the X-ray imaging system of the display 17. The notification icon 91 can be, for example, a cartoon shape. In addition, the notification icon 91 is always displayed.

Upon receiving the X-ray image 30 in the console 16, as shown in fig. 7, the CPU43 starts the operations of the image acquisition unit 61, the image processing unit 62, the display instruction receiving unit 63, and the display control unit 64. The image acquisition unit 61 receives the X-ray image 30 and transmits it to the image processing unit 62. The image processing unit 62 analyzes the X-ray image 30. As shown in fig. 8, the imaging error determination unit 71 determines an imaging error in the X-ray image 30. The determination is made using the learned model 72 a.

When the analysis is completed and the X-ray image 30 is an imaging error as a result of the analysis, the imaging error reason determining unit 73a determines the imaging error reason based on the information from the imaging error determining unit 71 and, in some cases, the imaging command 21 and/or the image file 31. The reason for the shooting error determination unit 73a determines a correction reason corresponding to the reason for the shooting error by using the determined reason and the shooting error reason/correction information table 52a stored in the shooting error reason DB52, and in some cases, by using the shooting command 21 and/or the information such as the image file 31.

In the notification screen 93 of the display 17, in order to notify the operator that the captured X-ray image 30 has been a failure in imaging, the expression of the notification icon 91 is changed and displayed. That is, as shown in fig. 18, after the X-ray imaging, if the result of the analysis is not a photographing error, the notification icon 91 is displayed as a notification icon 91a for notifying that there is no expression of the closed mouth, whereas if the result of the analysis is a photographing error, the notification icon 91 is displayed as a notification icon 91b for notifying that there is an expression of the open mouth.

The operator checks the display 17 to confirm the captured X-ray image 30, and therefore also checks the notification icon 91 displayed on the display 17 (fig. 15, step ST 100). In this case, the notification icon 91 is the notification icon 91b in which a notification is made. When it is desired to confirm the correction information or the reason for the shooting error (yes in step ST 110), the operator clicks the notification icon 91 with the cursor 92 using a mouse or the like in some cases (see fig. 17, step ST 120). By this operation, as shown in fig. 19, the management screen 90 of the X-ray imaging system is changed from the notification screen 93 to the correction information display screen 94. The correction information display screen 94 is a screen including the reason for the shooting error and/or the correction information display unit 96. The photographing failure reason and/or correction information display section 96 includes a photographing failure reason display section 96a and/or correction information display section 96b, an approval button 98, and a non-approval button 99. When the display deviation amount display 87 is set, the display deviation amount display 87 is displayed as shown in fig. 20.

After confirming the reason for the imaging error and/or the display contents of the correction information display unit 96, the operator determines that the X-ray image 30 displayed on the display 17 is not an imaging error (no in step ST 130), and clicks the non-ok button of the notification icon 91 (step ST 140). This enables editing and changing of data of the image file 31 input as a shooting error. Editing is performed as necessary if the input is not a shooting error (step ST160), and a determination is input that the input is not a shooting error (yes in step ST 190).

On the other hand, when the X-ray image 30 displayed on the display 17 is determined to be an imaging error and there is no difference in the reason for the imaging error and/or the contents indicated by the correction information display unit 96 (yes in step ST 130), the ok button 98 of the notification icon 91 is clicked (step ST 150). When the ok button 98 is clicked, an imaging error process of the X-ray image 30 is automatically performed (step ST 180). In the display 17, the reason for the shooting error and/or the correction information display 96 disappears, and the notification icon 91 becomes the notification icon 91a without notification, and returns to the standby state before shooting.

When it is determined that the X-ray image 30 displayed on the display 17 has an imaging error and there is an objection to the reason for the imaging error and/or the contents indicated by the correction information display unit 96 (no in step ST 130), buttons for determining an imaging error, and editing the correction information and the reason for the imaging error are displayed when the non-ok button is clicked. When editing is not performed, it is assumed that editing is completed, and when editing is performed, each editing button is clicked to edit the determination of an imaging error, correction information, and the reason for the imaging error (step ST 160). When the determination of the imaging error of the X-ray image 30 is confirmed (no in step ST 190), the result is transmitted to the imaging error processing (step ST180), and the determination of the imaging error by the operator is ended.

Even when the notification icon 91b is displayed and the image processing unit 62 determines that the X-ray image 30 displayed on the display 17 has an imaging error, the operator can perform the imaging error processing by clicking the imaging error button 97 (step ST170) without clicking the notification icon 91 to display correction information (no in step ST 110) at his/her discretion. This automatically performs the shooting error process (step ST 180). When the operator has performed a process of a shooting error on the X-ray image 30, the notification icon 91 becomes the notification icon 91a without notification, and returns to the standby state before shooting.

The imaging error process automatically performed after the approval button 98 is clicked or after the imaging error button 97 is clicked includes, for example, transmitting data to the imaging error management device, registering a shooting command for re-shooting, and inputting a corresponding part of the DICOM-compliant file. In this case, the approval receiving unit 81 acquires necessary information from the image processing unit 62 and transmits the acquired information to the communication unit 44. The communication unit 44 transmits various information to each unit. This completes the transmission to the PACS, RIS, and imaging error management apparatus. Then, the operations of the units 80 to 84 of the CPU67 are stopped.

In the above embodiment, the hardware configuration of the processing unit (processing unit) that executes various processes, such as the image acquisition unit 61, the image processing unit 62, the display control unit 64, the display instruction receiving unit 63, and the approval receiving unit 81, is a processor (processor) of various types as shown below. The various processors include a Programmable Logic Device (PLD) such as a CPU (central processing unit) or an FPGA (field programmable gate array) that is a general-purpose processor that executes software (program) and functions as various processing units, and a dedicated electrical circuit (GPU/graphics processor) that is a processor having a circuit configuration designed specifically to execute various processes.

One processing unit may be constituted by one of these various processors, or may be constituted by a combination of two or more processors of the same kind or different kinds (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, and a combination of a GPU and a CPU). Further, a plurality of processing units may be configured by one processor. As an example in which a plurality of processing units are configured by one processor, the 1 st embodiment is a system in which one processor is configured by a combination of one or more CPUs and software, as typified by a computer such as a client or a server, and functions as a plurality of processing units. The 2 nd System uses a processor in which the functions of the entire System including a plurality of processing units are realized by one IC (Integrated Circuit) Chip, as represented by a System On Chip (SoC) or the like. In this manner, the various processing units are configured using one or more of the various processors as a hardware configuration.

More specifically, the hardware configuration of these various processors is an electric circuit (circuit) in a system in which circuit elements such as semiconductor elements are combined.
