(Operation of X-ray imaging system)
Next, the imaging process in the X-ray imaging system 1 shown in FIG. 3 will be explained.
Here, it is assumed that an examination order is registered in the imaging control device 11 in advance. The examination order may be input from an external system such as the HIS 32 or the RIS 33, or may be manually input through the operation unit 114 by a user who performs imaging (a technician, an interpreter, a diagnostician, etc.).

(shooting processing)
In the imaging process, first, the control unit 111 of the imaging control device 11 displays the examination screen 113a shown in FIG. 4 on the display unit 113, and receives selection of an examination order for imaging by the imaging operator (step S1). By pressing the imaging selection button A1, the radiographing operator selects the examination order for which radiography is to be performed from among the registered examination orders.

FIG. 4 shows an example of the inspection screen 113a displayed on the display unit 113.
The examination screen 113a includes an imaging selection button A1 on which the contents of each imaging included in the examination order information (exposed body part, imaging direction, etc.) are displayed, as well as a setting area A2 for adjusting the image of the selected imaging; An image display area A3 for displaying the photographed image, a photograph loss button A4, an image output button A5 for outputting the image to an external device, a switching button A7 for switching the image displayed in the image display area A3 (first operation) section), an inspection end button A8, etc. are provided. Note that at the stage of step S1, no image is displayed in the image display area A3 yet.

When an examination order is selected, the control unit 111 transmits and sets the imaging conditions included in the examination order to the X-ray generation control device 21 and FPD 12 (step S2).
During this time, the person performing the imaging positions the subject between the X-ray tube device 25 and the imaging table 13. Here, positioning refers to, for example, how the subject's body position is taken during imaging. Furthermore, the person performing the imaging instructs the subject, for example, about the breathing state (deep breathing, etc.).

Next, the control unit 111 receives a pressing operation of the irradiation switch 23 by the person performing the imaging, and performs imaging (step S3).
When the irradiation time is set, such as in simple X-ray photography, the X-ray irradiation ends when the predetermined irradiation time has elapsed. In the case of dynamic imaging, X-ray irradiation is performed continuously while the irradiation switch 23 is pressed down to the second stage, and when the irradiation switch 23 is released, X-ray irradiation continues. ends.
The photographed image is transmitted from the FPD 12 to the photographing control device 11.
Here, it is assumed that the person performing the photographing has performed the above-mentioned photographing a plurality of times. That is, the control unit 111 acquires a plurality of radiographic images (a plurality of radiographic images satisfying a predetermined condition) taken by the same radiographer. Note that multiple radiographic images that meet the above predetermined conditions include multiple radiographic images associated with a test order, multiple radiographic images taken of the same patient, multiple radiographic images taken on the same imaging day, and multiple radiographic images of the same radiographed area. It may be a plurality of radiographic images taken or a plurality of radiographic images taken within a predetermined period of time. In addition, the plurality of radiographic images that meet the predetermined conditions may be a plurality of radiographic images taken in one examination, and the plurality of radiographic images may be performed by different radiographers, different parts of the body, or different departments. Good too. Furthermore, the plurality of radiographic images may satisfy a plurality of conditions among the following: same subject, same imaging date, same imaging site, same imaging operator, and imaging within a predetermined time. Further, the plurality of radiographic images satisfying the above-mentioned predetermined conditions may be a plurality of frame images taken by one dynamic imaging. Further, the plurality of radiographic images satisfying the above-mentioned predetermined conditions may be a plurality of frame images taken by a plurality of dynamic imaging in one examination.
Then, as shown in FIG. 4, the control unit 111 displays the acquired image A31 and the photographing conditions A32 for the photographing in the image display area A3.

Next, the control unit 111 receives a judgment by the photographer as to whether or not the image displayed in the image display area A3 is a defective image (determination of a defective image) (step S4). If the person who takes the photograph is determined to have failed the photograph, he or she presses the failure button A4.
When the judgment of whether the image is defective or not is completed, the person performing the photographing releases the subject from the positioning state.

Next, the control unit 111 receives an instruction from the user to perform post-processing on the image via the operation unit 114, executes the post-processing (step S5), and moves the main process to step S1 to perform the next process. Move on to shooting. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.
The above post-processing includes ROI (Region Of Interest) adjustment, effective image area setting, S/G value adjustment, rotation/reversal/arbitrary angle rotation, image processing (E processing/F processing/H processing/scattered radiation correction/image processing At least one of the following: (condition change, etc.), emphasis processing (frequency emphasis (catheter tip emphasis processing, gauze emphasis processing/other emphasis processing, etc.), grid eye removal processing, masking, trimming, marker/stamp/overlay, output settings) including.
Further, in step S5, the control unit 111 stores the results of post-processing on the image (whether or not to perform the post-processing and the content of the post-processing) in the storage unit 112.

(switching process)
Next, the switching process executed by the control unit 111 in step S5 will be described.
The switching process is a process of switching the image displayed in the image display area A3 based on an input operation by the user via the operation unit 114. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.
Specifically, when the user instructs execution of a specific process on the image displayed in the image display area A3, the control unit 111 sets the specific process as the last process in the post-processing, and in this case, The image displayed in the image display area A3 is switched to the next image. Thereby, it is possible to reduce the user's operation to select the next image.
Switching the image displayed in the image display area A3 to the next image means switching the image of the next examination order displayed in the examination order list A11 shown in FIG. image). Further, when one photograph corresponding to the photograph selection button A1 has a plurality of images, switching may be performed to the next image among the plurality of images. Further, the shooting selection button A1 to be switched to is not limited to a shooting selection button A1 that has already been shot (a shooting selection button A1 having a shot image), but may be an unshot shooting selection button A1 that is scheduled to be shot in the future. In addition, the imaging selection button A1 to be switched to is the next imaging selection button A1 in the order of arrangement in the inspection order list A11, one of the imaging selection buttons A1 that has already been taken, and one of the imaging selection buttons A1 that has not yet been taken. It may be set in advance from any of the following.

For example, in post-processing, the image output button A5 is likely to be pressed last, so when the user presses the image output button A5, the control unit 111 changes the image to be displayed in the image display area A3 to the next image. Switch to image. That is, in this case, the image output button A5 functions as a second operation section having a different function from the switching button A7 (first operation section). Then, when the processing unit switches between a plurality of radiation images and executes post-processing (predetermined processing), the control unit 111 selects the image output button A5 (second operation unit) to display the radiation image to be displayed on the display unit 113. Assign the function to switch.

Further, for example, when the user instructs to perform catheter tip enhancement processing, gauze enhancement processing, masking, etc. as post-processing on the image displayed in the image display area A3, the control unit 111 controls each enhancement processing image. The image displayed in the image display area A3 may be switched to the next image after a predetermined period of time has elapsed (for example, several seconds) after the image is displayed. These enhancement processes are often used to confirm the condition after surgery, and as long as the enhancement processed image can be confirmed, the purpose of the photographed image is completed. It is determined that the processing of
Further, for example, when the user instructs to perform ROI adjustment as post-processing on the image displayed in the image display area A3, the control unit 111 executes ROI adjustment after a predetermined period of time (for example, After several seconds), the image displayed in the image display area A3 may be switched to the next image.
Further, for example, when the user instructs full-screen display in post-processing for the image displayed in the image display area A3, the control unit 111 displays the image displayed in the image display area A3 after a predetermined period of time has elapsed (for example, , several seconds later), the image displayed in the image display area A3 may be switched to the next image. For example, when displaying images on a portable terminal used for medical rounds, etc., the screen of the portable terminal is small, so the image after post-processing can be enlarged and checked in full-screen display, and if there are no problems, post-processing can be done. There are times when it ends. In this case, if there is no input (touch operation) on the portable terminal for several seconds after full-screen display is performed, the display may be switched to the next image.
In other words, in this case, the button on the examination screen 113a that instructs execution of catheter tip enhancement processing, gauze enhancement processing, masking, ROI adjustment as post-processing, or full screen display is the switch button A7 (first operation section). is a second operation section having a different function, and is a button for inputting that the post-processing (predetermined processing) by the processing section has been completed.

Note that the button that functions as the second operation unit can be set for each body part to be imaged, user, type of examination, type of image, or requesting department. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.

As explained above, by performing the switching process, it is possible to reduce the user's operation to select the next image, so that predetermined processing (post-processing) can be performed more efficiently on multiple radiographic images. Can be done.

In step S5 of the photographing process, in order to reduce the number of operations by the user, for example, if the user instructs to perform gradation processing as post-processing on the image displayed in the image display area A3, then Since the possibility of changing the frame of the effective image area is low, the control unit 111 may set the frame of the effective image area at that time as the trimming frame.

(Modified example)
Next, a modification of the first embodiment will be described. Below, differences from the first embodiment will be mainly explained.

In this modification, the operation unit 114 functions as a third operation unit that can be operated by the user. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.
Furthermore, the control unit 111 determines whether the post-processing (predetermined processing) is completed based on the operation performed by the user on the operation unit 114 (third operation unit). Here, the control unit 111 functions as a determination unit.
The control unit 111 also controls the processing unit 111 when the processing unit switches between a plurality of radiographic images and executes post-processing (predetermined processing), and when the judgment unit determines that the post-processing (predetermined processing) has been completed. , switches the radiation image displayed on the display unit 113.

In the switching process of this modification, if the user performs a specific operation within the inspection screen 113a, the control unit 111 determines that the post-processing of the image currently displayed in the image display area A3 is completed. In this case, the control unit 111 switches the image displayed in the image display area A3 to the next image.
For example, when the user double-clicks an area in the image display area A3 where the image A31 is not displayed or outside the trimming frame, the control unit 111 completes the post-processing of the image currently displayed in the image display area A3. I judge that I did. Then, the control unit 111 switches the image displayed in the image display area A3 to the next image.
Further, for example, when the user drags and drops a trimming frame in the image display area A3, the control unit 111 determines that post-processing on the image currently displayed in the image display area A3 is completed. Then, the control unit 111 may switch the image displayed in the image display area A3 to the next image after a predetermined period of time (for example, several seconds) has passed since the trimming frame was dropped.

(others)
In addition, in step S5 of the photographing process, it is preferable to reduce the user's work burden by limiting the user's operation range within the inspection screen 113a.
For example, the control unit 111 displays an enlargement button and a reduction button in the setting area A2 as one button on the inspection screen 113a, and enlarges the button depending on the location within the button and the method of depression (for example, double-clicking or long-pressing). You may also switch between performing the following: In addition to the enlargement button and reduction button, the control unit 111 displays nearby or related functions (buttons) as one button, and determines which function is to be performed depending on where and how the button is pressed. You may switch.
Thereby, it is possible to narrow the operation range within the inspection screen 113a for the user who instructs the execution of post-processing, or to make the operation location larger so that it is easier to press the button, thereby reducing the user's work burden.

<Second embodiment>
Next, an X-ray imaging system 1 according to a second embodiment will be described. Below, differences from the first embodiment will be mainly explained.

In this embodiment, the control unit 111 performs post-processing (predetermined processing) on the first radiographic image and then performs post-processing (predetermined processing) on the second radiographic image. According to the post-processing (predetermined processing) performed on the second radiation image, the display mode of the operation unit displayed on the display unit 113 for performing the post-processing (predetermined processing) on the second radiation image is determined. Here, the control section 111 functions as a display control section.

(Display control processing)
Next, the display control process executed by the control unit 111 in step S5 of the photographing process in this embodiment will be described.
As display control processing, when the image displayed in the image display area A3 is switched to the next image, the control unit 111 maintains the display mode for executing a specific process, and maintains the display mode for executing the process again. Reduce user selection operations. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.
The specific process is the last process performed on the image displayed in the image display area A3, a preset process, or the like.
Further, the specific process may be set depending on the region to be imaged or the imaging conditions.

For example, when the user instructs execution of a specific process on the image to be displayed in the image display area A3 via the sub-panel A21 (see FIG. 5), the control unit 111 changes the image to be displayed in the image display area A3 to the next one. When switching to an image, the sub-panel A21 is displayed within the inspection screen 113a. The sub-panel A21 is a screen displayed by the control unit 111 when a predetermined button in the setting area A2 is pressed by the user.
In other words, when performing post-processing on a second radiation image (an image following the first radiation image) after performing post-processing on the first radiation image, the control unit 111 performs post-processing on the first radiation image. According to the post-processing performed, the display mode of the operation unit displayed on the display unit 113 for performing the post-processing on the second radiation image is determined and displayed. In this case, when performing post-processing on the second radiographic image, the control unit 111 controls the display mode of the operation unit (the state in which sub-panel A21 is displayed) when the post-processing is performed on the first radiographic image. ) is decided to be maintained. In other words, the operation unit includes buttons in the setting area A2 (first button group) and a sub-panel A21 (second button group) that is displayed by the control unit 111 (display control unit) when the first button group is pressed. and has. If the second button group is displayed when post-processing (predetermined processing) is performed on the first radiation image, the control unit 111 (display control unit) controls the post-processing (predetermined processing) on the second radiation image. When executing a predetermined process), it is determined that the second button group is to be displayed.

In addition to the sub-panel A21 described above, the control unit 111 may display a dialog display, a tree structure, etc. for executing a specific process.
For example, when performing catheter tip enhancement processing or gauze enhancement processing as post-processing, the control unit 111 changes the enhancement level of the enhancement processing when switching the image displayed in the image display area A3 to the next image. A dialog is displayed within the inspection screen 113a.
Further, for example, when the setting area A2 has a hierarchical structure or a tree structure and the user instructs execution of a specific process via the setting area A2, the control unit 111 displays the image in the image display area A3. When switching the image to the next image, the hierarchical structure or tree structure of the setting area A2 may be displayed in an open state.

Further, the control unit 111 may perform display control in the display control process according to the imaging situation (type of examination order).
For example, a case will be described in which a catheter tip emphasizing process or a gauze emphasizing process is executed as post-processing. In this case, when the control unit 111 switches the image displayed in the image display area A3 to the image of the next examination order and the next examination order has not yet been photographed, the control unit 111 displays a dialog box for changing the emphasis level of the emphasis processing. is not displayed. Further, when the next inspection order is in a photographed state immediately after photographing (when determining whether the photograph is defective), the dialog is displayed on the inspection screen 113a. Further, if the next inspection order is in a photographed state at the time of post-processing, the dialog will not be displayed. That is, the control unit 111 determines the display mode of the operation unit displayed on the display unit 113 according to the shooting situation.

Display control may also be performed. The user here may be a technician other than the person performing the imaging, an interpreting doctor, a diagnosing doctor, or the like.

Further, as display control processing, the control unit 111 may perform display control on the inspection order list A11 according to the result of post-processing (whether or not it is performed and the content of the post-processing). That is, the control unit 111 determines the display order of the examination orders (imaging orders) on the display unit 113 depending on the state of post-processing.
For example, in the inspection order list A11, the control unit 111 displays the imaging selection buttons A1 from the top in the order in which images are output or in the order in which post-processing is performed.
For example, in the examination order list A11, the control unit 111 displays the imaging selection buttons A1 in the order in which imaging is performed from the top, displays them all at once in the same imaging region, or gives priority to those that have not been judged as defective. It may be displayed at the top.
Furthermore, for example, if the control unit 111 has a function of determining whether or not post-processing needs to be performed on captured images, in the inspection order list A11, it is necessary to perform post-processing. The shooting selection button A1 corresponding to the image determined to be available may be preferentially displayed at the top.

In addition, when performing the same specific process on multiple images as post-processing, the control unit 111 preferentially displays the imaging selection button A1 corresponding to the target image of the specific process at the top of the inspection order list A11. You may.
For example, when adding irradiation directions and the like to multiple images using the same overlay, the shooting selection button A1 corresponding to the image to be added may be preferentially displayed at the top.
Further, the control unit 111 may display the imaging selection buttons A1 in the order set in advance for each user or facility in the examination order list A11.

As described above, in the switching process, the control unit 111 switches the image displayed in the image display area A3 to the next image in the order displayed from the top in the inspection order list A11.
