Technical Field

The present invention relates to a radiographic imaging system for imaging a subject using radiation such as X-rays, a method of operating the radiographic imaging system, and a console for the radiographic imaging system.

Background

In the medical field, diagnosis is performed using a radiographic image obtained by imaging a subject irradiated with radiation by a radiation detection unit. When a radiographic image is captured, an imaging menu for specifying an imaging position, orientation, and orientation with respect to a radiation source that emits radiation is registered in advance, and imaging control of the radiation source or the radiation detection unit is performed based on the set imaging menu. A plurality of imaging menus are provided, and an imaging menu corresponding to an imaging command from a doctor, which is an imaging requester, is selected from the plurality of imaging menus. In facilities where an RIS (Radiology Information System) is introduced, an imaging menu can be automatically registered in accordance with an imaging command, but in facilities where an RIS is not introduced, an engineer using a radiation detection unit needs to manually register the imaging menu.

In contrast, in patent document 1, assuming registration of an imaging menu in a facility in which an RIS is not introduced, the positioning of an object is imaged by a camera provided on the radiation source side, and the imaging menu is registered using a positioning image obtained by imaging.

Disclosure of Invention

Technical problem to be solved by the invention

When a plurality of shooting menus are included in the shooting command from the RIS, the subject is usually shot in the order of the shooting menus set in advance in the shooting command. However, depending on the condition of the subject, i.e., the patient, it may be preferable to change the order of the preset imaging menu to image the subject. In this case, the engineer instructs the subject to change the positioning based on the changed shooting menu. Then, the engineer needs to move to a console installation room different from the imaging room in which radiography is performed, and operate the console to change the settings to the changed imaging menu. In this way, it takes time and labor to change the setting of the shooting menu, and there is a possibility that an error may occur in connection with the operation of changing the setting of the shooting menu.

On the other hand, patent document 1, which uses a camera to photograph the subject, is conceivable, but since patent document 1 assumes radiography in a facility into which an RIS is not introduced, an imaging menu is not registered at the start of imaging. Therefore, in patent document 1, the positioning image captured by the camera is not used for automatic selection from the registered shooting menu, but is used for setting the shooting menu.

The present invention aims to provide a radiation imaging system, an operating method thereof and a console for the radiation imaging system, which can eliminate labor and time required for setting change of an imaging menu accompanying the change of the positioning of an object even when the positioning of the object relative to a radiation source is changed according to the state of the object.

Detailed Description

As shown in fig. 1, a radiographic imaging system 10 captures a radiographic image by using radiation to photograph an object. The radiation imaging system 10 includes a radiation source 11, a radiation detection unit 12, a positioning imaging device 13, a console 15 (console for radiation imaging system), and a display unit 16. The radiation source 11, the radiation detection unit 12, and the positioning imaging device 13 are disposed in an imaging room 17 in which an object H is imaged. The console 15 is connected to the radiation source 11, the radiation detection unit 12, and the positioning imaging device 13, and is installed in a console installation room 18 different from the imaging room 17.

The radiation source 11 is disposed opposite to the radiation detection unit 12. The radiation source 11 irradiates a subject H facing the radiation detection unit 12 with radiation such as X-rays and gamma-rays in accordance with an imaging instruction from the console 15. The radiation detection unit 12 detects radiation transmitted through the subject in accordance with an imaging instruction from the console 15, and obtains a radiation image. The obtained radiation image is sent to the console 15. The console 15 performs various image processing on the radiographic image. The radiation image subjected to various image processing is displayed on the display unit 16.

The positioning imaging device 13 is preferably a visible light camera for taking a subject H illuminated with visible light. The positioning imaging device 13 is attached to the radiation source 11 side such as near the radiation source 11, and includes the subject H facing the radiation detection unit 12 in the field of view of the positioning imaging device 13. The positioning imaging device 13 captures an image of the subject H facing the radiation detection unit 12, and obtains a positioning image of the subject H. The positioning image is preferably an image obtained by positioning the positioning imaging part, the posture, and the orientation of the subject H with respect to the radiation detection unit 12 by an engineer. The obtained positioning image is sent to the console 15.

As will be described later, the positioning image is used for selection of a photographing menu in the console 15. The positioning image may be acquired in accordance with a positioning imaging instruction from the console 15. In addition, the positioning image may be transmitted to the console 15 at a timing when the shooting menu is selected in a state where the positioning image can be always acquired.

As shown in fig. 2, the console 15 includes a shooting command receiving unit 20, a shooting menu registration memory 21, a shooting menu selecting unit 22, and a system control unit 23. The console 15 is used for an engineer to operate the radiation source 11 or the radiation detection section 12, and the like. The imaging command receiving unit 20 receives an imaging command transmitted from an external RIS (radiology Information System). The shooting command is displayed on the display unit 16 at an appropriate timing. Further, registration of a photographing order for the RIS is performed by a photographing requester such as a doctor in a clinical department.

In the console 15, a program related to a process of selecting a shooting menu or the like is incorporated in a program memory (not shown). The program functions as a photographing command receiving unit 20, a photographing menu selecting unit 22, a positioning recognizing unit 30, a comparing unit 32, an alarm generating unit 36, and the like by operating a system control unit 23 including a processor.

As shown in fig. 3, the shooting command includes a command ID (Identification Data), an object ID, a shooting menu, and the like. The command ID is a symbol or number (for example, "OD 0001") for identifying each photographing command and is automatically assigned by the RIS. The object ID is a symbol or number (e.g., "H0500") for identifying the object H. In addition to the RIS, the photographing command may be transmitted from the HIS (hospital information System).

The imaging menu is information related to imaging of the subject H and is information necessary for diagnosis based on a radiographic image. Specifically, the shooting menu includes information (for example, "chest", "prone", "front", and the like) related to the positioning shooting part, posture, and orientation of the subject H. The positioning imaging portion of the subject H is, for example, a head, a cervical vertebra, a chest, an abdomen, a hand, a finger, an elbow, or the like. The posture of the object H is, for example, the front, side, back, and the like with respect to the object H of the radiation source 11. In addition, the shooting command is provided with items of subject information such as the name, sex, age, height, weight, and the like of the subject H. The imaging order 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 was received by the RIS, the post-operation periodic observation, the effect determination of the therapeutic agent, and the like, and notification items of the imaging requester to the engineer.

The photographing menu registration memory 21 registers in advance one or more photographing menus among the photographing commands received from the RIS. Then, the shooting menu is registered in the shooting menu registration memory 21, and the shooting conditions corresponding to the shooting menu are registered in association with the shooting menu. The system control unit 23 controls imaging of the radiation source 11 or the radiation detection unit 12 in accordance with the imaging menu registered in the imaging menu registration memory 21. The imaging control includes at least control such as irradiating the radiation from the radiation source 11 to the subject H and detecting the radiation transmitted through the subject to obtain a radiation image, and also includes processing the radiation image by the console 15 and displaying the processed radiation image on the display unit 16. In the imaging control, it is preferable that the user starts the imaging control by operating the user interface 34 connected to the console in accordance with an instruction of radiography by the user.

In the photographing menu registration memory 21, the relationship between the photographing menu and the photographing condition is stored in a photographing menu table (not shown) in advance. The imaging conditions include irradiation conditions such as a tube voltage, a tube current, and irradiation time of the radiation source 11, driving conditions of the radiation detection unit 12, image processing conditions related to image processing of the radiation image obtained by the radiation detection unit 12, and the like.

When there are a plurality of shooting menus, the shooting menu registration memory 21 sets a shooting control order based on the shooting menus as a specific order. For example, when the shooting menu includes four shooting menus a ("chest", "prone position", "front"), B ("chest", "prone position", "back"), C ("chest", "prone position", "left side"), and D ("chest", "prone position", and right side "), the order of the shooting menus a, B, C, and D is set to a specific order as shown in fig. 4. Basically, shooting by the shooting menu is performed in a specific order.

However, as described above, when there are a plurality of shooting menus, the subject H needs to change the positioning in accordance with the number of shooting menus. In order to reduce the burden on the subject H caused by changing the positioning, the positioning of the subject may be guided by an engineer. In view of this, in the present embodiment, the positioning of the subject H guided by the engineer is photographed by the positioning photographing device 13, and the photographing menu corresponding to the positioning image obtained by the photographing is automatically selected by the photographing menu selecting section 22. Then, the system control unit 23 performs imaging control in accordance with the imaging menu selected by the imaging menu selection unit 22. That is, the system control unit 23 can perform the shooting control by the shooting menu in a different order from the specific order registered in the shooting menu registration memory 21.

Specifically, first, it is preferable that the positioning recognition unit 30 (see fig. 2) of the console 15 recognize the positioning of the subject H from the positioning image. Further, it is preferable that the shooting menu selection unit 22 selects a shooting menu corresponding to the position of the subject H recognized by the position recognition unit 30, among the shooting menus registered in the shooting menu registration memory 21, as a shooting menu corresponding to the position image.

The position of the subject H recognized by the position recognition unit 30 is preferably information on the position, orientation, and direction of the subject H. For example, the object H is positioned in "chest", "prone", "front", and the like. As shown in fig. 5, the positioning recognition unit 30 is preferably a learning-completed processing unit 40 for positioning recognition in which the relationship between the positioning image and the positioning of the subject H is machine-learned. The positioning recognition learning completion processing unit 40 preferably performs machine learning using a machine learning processing unit 42 provided in the console 15 or an external processing device connected to the console 15. The learning-completed processing unit 40 for positioning recognition is preferably a processing unit configured by NN (Neural Network), CNN (Convolutional Neural Network), Adaboost (iterative algorithm), random forest, or the like, for example.

As shown in fig. 6, when the front of the chest of the subject H in the lying position of the radiation source 11 is positioned, a positioning image captured by the positioning imaging device 13 in this state is acquired. Then, the positioning recognition unit 30 recognizes the positioning of the subject H from the positioning image, and the imaging menu selection unit 22 automatically selects the imaging menu a ("chest", "prone", or front ") corresponding to the positioning of the subject H recognized by the positioning recognition unit 30. Then, the shooting menu a performs shooting control. At this point, the particular order is still followed.

Next, when it is considered that the burden on the subject H can be reduced more than positioning the chest of the subject H from the front to the rear, the engineer guides the subject H to position the chest from the front to the left. Further, when the chest of the subject H in the lying position is positioned on the left side with respect to the radiation source 11, a positioning image captured by the positioning imaging device 13 in this state is obtained. Then, the positioning recognition unit 30 recognizes the positioning of the subject H from the positioning image, and the imaging menu selection unit 22 automatically selects the imaging menu C ("chest", "prone position", and left side ") corresponding to the positioning of the subject H recognized by the positioning recognition unit 30. Then, the photographing menu C performs photographing control. At this time, the imaging control is performed in a different order from the specific order.

Next, when the chest of the subject H is changed from the left side to the right side, a positioning image captured by the positioning imaging device 13 in this state is obtained. Then, the positioning recognition unit 30 recognizes the positioning of the subject H from the positioning image, and the imaging menu selection unit 22 automatically selects the imaging menu D ("chest", "prone position", and right side ") recognized by the positioning recognition unit 30. Then, the shooting menu D performs shooting control. At this time, the imaging control is also performed in a different order from the specific order.

Next, when the chest of the subject H is changed from the right side to the back side, a positioning image captured by the positioning imaging device 13 in this state is obtained. Then, the positioning recognition unit 30 recognizes the positioning of the subject H from the positioning image, and the imaging menu selection unit 22 automatically selects the imaging menu B ("chest", "prone position", and back ") corresponding to the positioning of the subject H recognized by the positioning recognition unit 30. Then, the shooting menu B performs shooting control. At this time, the imaging control is also performed in a different order from the specific order.

In addition, regarding acquisition of the positioning of the subject H, the positioning of the subject H may be obtained by pattern matching between model data set in advance so as to correspond to the positioning of the subject H and the positioning image by the comparison unit 32 in the console 15. In this case, the shooting menu selection unit 22 selects a shooting menu corresponding to the position of the subject H obtained by pattern matching as a shooting menu corresponding to the position image. As the preset model data, there is a radiation image of the subject H obtained in a state where the subject H is positioned corresponding to a plurality of imaging menus. As the location of the subject H obtained by pattern matching between the model data and the location image, specifically, information relating to the location imaging part, posture, and orientation of the subject H is preferable. For example, the object H is positioned in "chest", "prone", "front", and the like.

Next, a series of processes of the present invention will be described with reference to a flowchart shown in fig. 7. When the subject H, which is a subject to be imaged with a radiographic image, enters the imaging room 17, it is disposed between the radiation source 11 and the radiation detection unit 12 under the guidance of an engineer. When the subject H faces the radiation detection section 12 and is positioned at a specific position with respect to the radiation source 11 by guidance of an engineer, the positioning imaging device 13 images the subject H in the specific positioning state. Thereby, a positioning image is obtained.

Next, when the positioning image is obtained, the positioning recognition unit 30 recognizes the positioning of the subject H from the positioning image. The shooting menu selecting unit 22 automatically selects a shooting menu corresponding to the position of the subject H recognized by the position recognizing unit 30 from among one or more shooting menus registered in advance in the shooting menu registration memory 21. When the imaging menu is selected, the system control unit 23 controls the radiation source 11 or the radiation detection unit 12 to perform imaging in accordance with the selected imaging menu. When a plurality of shooting menus are registered, the engineer guides the subject H from a specific position to another position (changes the position), and obtains a position image at the time of the other position. Also, in the same manner, the shooting menu corresponding to the positioning image at the time of other positioning is selected. Then, the user operates the user interface 34 to instruct radiography, and the system control unit 23 performs radiography control in accordance with the selected radiography menu. The same processing as described above is performed for all the shooting menus until the shooting control is finished. When the imaging control is finished for all the imaging menus, the radiography is finished.

In the above-described embodiment, when the imaging menu corresponding to the positioning image used for recognition of the positioning of the subject H is an imaging menu not registered in the imaging menu registration memory 21 and not included in the imaging command, the alarm generation unit 36 generates an alarm for the user when the user operates the user interface 34 and performs the 1 st operation to start radiography. As the alarm, it is preferable that a message to stop the radiography be displayed on the display unit 16. When the alarm is generated, the system control unit 23 preferably performs control to stop radiography (for example, stop radiation irradiation). In this case, when the user operates the user interface 34 and performs the 2 nd operation indicating that the radiography is approved, the unregistered radiography menu is automatically additionally registered in the radiography menu registration memory 21. Then, the shooting menu selection unit 22 selects a shooting menu to be automatically additionally registered. Then, the user operates the user interface 34 to give an instruction to perform radiography again, and the system control unit 23 performs radiography control in accordance with the additionally registered radiography menu.

For example, as shown in fig. 8, when the shooting menu included in the shooting order is the shooting menu a (chest/prone position/front), the shooting menu B (chest/prone position/back), the shooting menu C (chest/prone position/left side), and the shooting menu D (chest/prone position/right side), as shown in fig. 9, when the recognition result of the positioning recognized by the positioning recognition unit 30 is "abdomen/prone position/front", the shooting menu corresponding to the positioning of "abdomen/prone position/front" is the shooting menu not registered in the shooting menu registration memory 21, which is not included in the shooting order. When the 1 st operation of radiography is performed in the case of an unregistered radiography menu, an alarm is issued. Then, by the user performing the 2 nd operation of pressing the "ok" button of the user interface 34 in response to the alarm, the shooting menu registration memory 21 automatically additionally registers the shooting menu E corresponding to the "abdomen/prone position/front" positioning as shown in fig. 10. Then, the shooting menu selection unit 22 selects the additionally registered shooting menu E. Then, the user operates the user interface 34 to give an instruction to perform radiography again, and the system control unit 23 performs radiography control in accordance with the radiography menu E additionally registered.

In the above embodiment, the hardware configuration of the processing unit (processing unit) that executes various processes, such as the photographing command receiving unit 20, the photographing menu registration memory 21, the photographing menu selecting unit 22, the system control unit 23, the positioning recognizing unit 30, and the comparing unit 32, is a processor (processor) as described below. The various processors include a Programmable Logic Device (PLD) such as a CPU (Central Processing Unit/Central Processing Unit), a GPU (graphic Processing Unit/graphics Processing Unit), an FPGA (Field Programmable Gate Array) or the like, which is a general-purpose processor that executes software (program) to function as various Processing units and can change a circuit configuration after manufacture, and a dedicated electric circuit or the like, which is a processor having a circuit configuration specifically designed to execute various types of Processing.

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, a combination of a CPU and a GPU, or the like). 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 mode 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 the processor 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 typified 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. The hardware configuration of the storage unit is a storage device such as an HDD (hard disk drive) or an SSD (solid state drive).
