Technical Field
The present invention relates to a radiographic system that applies radiation to an examinee and captures radiographic images, and to a radiographic method and a storage medium.
Background
The radiographic apparatus applies radiation (e.g., X-rays) to an examinee, and detects an intensity distribution of the radiation that has passed through the examinee, thereby capturing a radiographic image of the object.
In an examination using radiation (radiographic examination), examination information including an imaging region and an imaging method is generally set by a physician. Radiographic imaging is then performed by the radiographic apparatus based on the set examination information.
Depending on the examination performed, the radiographic apparatus performs different image processing on one image to acquire a plurality of radiographic images. For example, in a chest examination, a copy process is performed on a chest image acquired by one imaging, and image processing for general chest diagnosis and image processing for pneumoconiosis (pneumoconiosis) diagnosis are performed in some cases to acquire two radiographic images. Further, in some cases, the radiographic apparatus may acquire a normal radiographic image in which the radiolucent portion is black and the radiopaque portion is white, and an inverted radiographic image in which black and white are reversed. Japanese patent application publication No.2014-83123 discusses a method of reproducing a radiographic image.
Disclosure of Invention
The sheet set for radiographic imaging does not include a copy instruction of a radiographic image. Therefore, it is necessary for a medical technician who performs radiographic imaging to provide a copy instruction for each imaging and perform image processing on radiographic images.
The present invention is directed to a radiographic system, a radiographic method, and a storage medium, each of which makes it possible to appropriately perform image processing based on an imaging protocol (imaging protocol) associated with an examination sheet, thereby efficiently performing radiographic imaging.
According to an aspect of the present invention, a radiography system includes: a storage unit configured to store a plurality of imaging methods in association with a plurality of imaging protocols; a determination unit configured to determine whether an imaging method of an imaging scheme associated with the examination order matches at least one imaging method of the plurality of imaging methods stored in the storage unit; and an image processing unit configured to apply, in a case where the determination unit determines that the imaging method matches the at least one imaging method, image processing conditions of the imaging scheme corresponding to the at least one imaging method to a radiographic image captured based on the imaging scheme associated with the examination order.
Further features of the present invention will become apparent from the following description of exemplary embodiments, which is to be read in connection with the accompanying drawings.

Each of these devices includes one or more computers. Each computer is provided with, for example, a main control unit (e.g., a Central Processing Unit (CPU)), a storage unit (e.g., a Read Only Memory (ROM) and a Random Access Memory (RAM)). Each computer may be provided with a communication unit (e.g., a network card) and an input/output unit (e.g., a keyboard, a display, and a touch panel). These constituent units are electrically connected via, for example, a bus, and are controlled when the main control unit executes a program stored in the storage unit.
As shown in fig. 1, a radiographic apparatus 1 that performs radiographic imaging is placed in an
The radiographic apparatus 1 includes a display unit 2 that displays a radiographic image and various information, an
The radiation generating apparatus 4 sets imaging conditions of radiation in the radiation generating unit 8, and controls generation of radiation from the radiation generating unit 8. The radiation generating unit 8 serves as a radiation source that generates radiation. The radiation generating unit 8 is realized by, for example, a radiation tube bulb (e.g., an X-ray tube), and applies radiation to an examinee 10 (e.g., a specific region of the examinee).
The radiation generating unit 8 can apply radiation to a desired irradiation range. An aperture (not illustrated) that shields radiation is provided on the irradiation surface of the radiation generating unit 8. The operator can adjust the irradiation range of the radiation emitted from the radiation generating unit 8 by controlling the aperture that shields the radiation.
The radiographic system includes a radiation detection device 7, and the radiation detection device 7 detects radiation emitted from a radiation generation unit 8. The radiation detection apparatus 7 detects radiation that has passed through the
Specifically, the radiation detection apparatus 7 detects radiation that has passed through the
The radiation detecting apparatus 7 is a portable cassette type radiation detecting apparatus, and is carried together with the radiation generating apparatus 4 to an
The radiation detection apparatus 7 performs a/D conversion on the detected electric charges to generate a radiographic image, and accumulates the radiographic image in a storage unit (not illustrated). The radiation detection apparatus 7 can provide image information (for example, an image ID, an imaging date, and a transmission status of the radiographic image) to the radiographic image, and transmit the image information to the radiographic apparatus 1 together with the radiographic image.

Fig. 3A to 3D are diagrams illustrating the determination by the
Further, in the imaging protocol table, the same imaging condition IDs of the imaging protocols indicate the same imaging conditions. For example, in fig. 3A, the imaging protocols ID P1, P2, and P3 have the same imaging condition ID EX 1. Therefore, the imaging conditions in the imaging protocols P1, P2, and P3 were the same. Likewise, the imaging protocols ID P4 and P5 have the same imaging conditions ID EX 2. Therefore, the imaging conditions in the imaging protocols P4 and P5 were the same.
In addition, in the imaging scenario table, the same image processing condition IDs of the imaging scenarios indicate the same image processing conditions. For example, in fig. 3A, the imaging scheme IDs P1 and P6 have the same image processing condition ID IP 1. Therefore, the image processing conditions in the imaging schemes P1 and P6 are the same. Likewise, the imaging scenario IDs P2 and P7 have the same image processing condition ID IP 2. Therefore, the image processing conditions in the imaging schemes P2 and P7 are the same.
Fig. 3B illustrates an imaging method table in which imaging method IDs of the imaging schemes shown in fig. 3A are classified. The imaging method table holds imaging method IDs. The imaging method table also holds imaging information about the examinee in radiographic imaging, such as an imaged region, an imaging direction, and an imaging posture. The distance between the radiation generating unit 8 and the radiation detecting apparatus 7 and the body thickness of the
In the imaging method table, when at least the imaged region and the imaging method are the same between the imaging method IDs, the imaging method is regarded as the same imaging method. For example, in fig. 3B, in the imaging method of each of the imaging methods ID T1 and T9, the imaged region is the chest and the imaging direction is posterior/anterior. Therefore, the imaged region and the imaging direction are the same between the imaging methods ID T1 and T9. Therefore, the imaging methods in the imaging method IDs T1 and T9 are the same.
The
As shown in fig. 3A, in the imaging protocol table, the same imaging method ID of the imaging protocol is regarded as the same imaging method. The
The pneumoconiosis process, which is the image process of the imaging protocol P3 for pneumoconiosis, is a process of applying image processes determined in advance for pneumoconiosis to generate radiographic images other than the radiographic image subjected to the ordinary image process. Specifically, the pneumoconiosis process differs from the general image process in image processing parameters related to tone (gradation) conversion, luminance, contrast, edge enhancement, and noise reduction for each frequency component.
In this case, the imaging scheme table shown in fig. 3A holds the imaging scheme stored in the
In a case where the imaging method included in the examinee's examination sheet matches the imaging method in the imaging protocol table, the
For example, when the imaging method ID of the imaging scheme associated with the new examination order is T1, the
In this example, even if, for example, the imaging postures are not the same, the imaging method ID T2 and the imaging method ID T9 shown in fig. 3B are determined as the same imaging method. In other words, when the imaging methods have at least the same imaged region and the same imaging direction, the imaging methods are determined to be the same imaging method. The determination
Fig. 3C illustrates an imaging condition table stored in the
As shown in fig. 3A, the imaging condition ID is also the same between the imaging protocol P1 for the chest PA and the imaging protocol P3 for the pneumoconiosis, in addition to the imaging method ID. The same imaging method ID and the same imaging condition ID indicate that imaging is performed with the same imaging method when the radiation generating apparatus 4 emits the same radiation. The

Fig. 4 illustrates a display form of the display unit 2 of the radiography system according to the present exemplary embodiment. Fig. 4 illustrates an imaging screen displayed on the display unit 2 after an examination to be performed is designated and the start of the examination is instructed. As shown in fig. 4, the display unit 2 displays a captured image display area 110, a subject information display area 104, an examination information display area 105, imaging protocol icons 109 (e.g., a chest PA icon 109a, a pneumoconiosis icon 109b, and a chest LL icon 109c) corresponding to imaging protocols, and an image
When the imaging screen is displayed, the imaging plan icon 109a set at the uppermost portion in the examination information display area 105 is selected by default. The
After the preparation for imaging is completed, the radiographic apparatus 1 transitions to an imageable state. At this time, a "ready" message indicating that the apparatus is in an imageable state is displayed on the message area 111.
At this time, based on the result of the determination by the
Next, the operator checks the imaging method, and performs setting of imaging and positioning of the examinee. After a series of imaging preparations are completed, the operator checks the imageable state with reference to the message area 111, and presses a radiation irradiation switch (not illustrated) of the radiation generating apparatus 4 that generates radiation. The radiographic apparatus 1 then causes the radiation generating unit 8 to apply radiation to a subject (for example, an imaged region of the subject), and causes the radiation detecting apparatus 7 to detect the radiation that has passed through the subject. Thereby, imaging of the radiographic image is performed.
After the imaging is completed, the
The image displayed on the captured image display area 110 is changed by the operation of the imaging scheme icon whose imaging has been completed. At the time of completion of imaging, a radiographic image of the chest PA scheme corresponding to the chest PA icon 109a is displayed on the captured image display area 110. The operator can display a radiographic image of a pneumoconiosis plan by operating the pneumoconiosis icon 109 b.
After the image processing is completed, the radiographic apparatus 1 displays the captured image subjected to the image processing on the captured image display area 110. In order to change the contrast or the like of the captured image, the operator operates a contrast icon, a luminance icon, or the like provided in the image
Likewise, in order to change the extraction area of the output image, the operator operates, for example, the extraction icon 122 and the extraction box 126 to specify a desired extraction area. In order to provide a character string as diagnostic information, the operator operates, for example, the comment icon 123 to superimpose the character string exemplified as the comment 127 on the image. In the case where the orientation of the radiographic image is not suitable for diagnosis, geometric conversion is performed by using, for example, the rotation icon 120 and the inversion icon 121. In the case where the radiographic image is not suitable for diagnosis, the setting for re-imaging or rejection is performed by using, for example, the re-imaging icon 124 and the rejection icon 125. As described above, the operator can additionally edit the radiographic image displayed on the captured image display area 110.
The operator repeats the above-described process to perform imaging corresponding to all the imaging icons in the examination information display area 105. After all imaging is performed, the operator presses the examination end icon 113. Thereby, the inspection series ends.
Next, the application of the imaging process and the image processing is described with reference to a flowchart shown in fig. 5.
