[0010] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the claimed invention. Although multiple features are described in the embodiments, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0011] (First embodiment) 1 shows an example configuration of an information processing system 100 according to a first embodiment of the present disclosure. The information processing system 100 is configured to electrically capture an optical image formed by radiation to obtain an electrical radiation image. The radiation is typically X-rays, but may also be α-rays, β-rays, γ-rays, etc. The information processing system 100 includes, for example, a radiation imaging device 110, a computer 120 serving as an information processing device, a display means 114, an exposure control device 130, and a radiation generation device 140.

[0012] The radiation generating device 140 starts irradiating radiation in accordance with an exposure command (radiation command) from the exposure control device 130. The radiation irradiated from the radiation generating device 140 passes through the subject 150 and enters the radiation imaging device 110. The radiation generating device 140 also stops irradiating radiation in accordance with a stop command from the exposure control device 130.

[0013] The radiation imaging device 110 is an imaging device that outputs a radiation image based on radiation. The radiation imaging device 110 includes a radiation detection panel 111 and a control circuit 112. The radiation detection panel 111 generates an image signal in response to radiation incident on the radiation imaging device 110. The image signal is data representing a radiation image. The control circuit 112 controls the operation of the radiation detection panel 111. Alternatively, the control circuit 112 generates a stop signal for stopping radiation irradiation from the radiation source 140 based on the image signal obtained from the radiation detection panel 111. The stop signal is supplied to the exposure control device 130. In response to the stop signal, the exposure control device 130 sends a stop command to the radiation generation device 140. The control circuit 112 may be configured, for example, by a programmable logic device (PLD) such as a field programmable gate array (FPGA) or a dedicated circuit such as an application specific integrated circuit (ASIC). Alternatively, the control circuit 112 may be configured by combining a general-purpose processing circuit such as a processor and a storage circuit such as a memory. In this case, the functions of the control circuit 112 may be realized by the general-purpose processing circuit executing a program stored in the storage circuit.

[0014] In the field of non-destructive testing, which involves testing non-inspected objects without destroying them, the exposure control device 130 and the computer 120 may not be connected for synchronization. In such cases, the user directly operates the exposure control device 130 to stop the radiation irradiation. Here, the non-inspected object is, for example, a printed circuit board or a pipe. For example, in the inspection of a pipe, the presence or absence of scratches on the inside and outside of the pipe, the deterioration state of the material that forms the pipe, etc. are inspected.

[0015] The computer 120, which serves as an information processing device, is connected to the exposure control device 130 and the radiation imaging device 110 so as to be able to communicate with them. Here, being able to communicate includes not only direct communication between the devices but also communication via other devices. Communication via other devices refers, for example, to a form in which the computer 120 communicates with the radiation generation device 140 via the exposure control device 130. The computer 120 has an exposure control unit (not shown) that controls the radiation imaging device 110 and the exposure control device 130, a receiving unit (not shown) that receives radiation images from the radiation imaging device 110, and a signal processing unit (not shown) that processes radiation images obtained by the radiation imaging device 110.

[0016] The computer 120 further includes a control unit 121 and a display control unit 122 .

[0017] The control means 121 accumulates a plurality of radiographic images to generate an accumulated image, and determines the image quality of the accumulated image. Here, accumulating a plurality of radiographic images means, in other words, adding a plurality of radiographic images together. The term "accumulation" also refers to adding a new radiographic image to an accumulated image obtained by accumulation. Here, determining the image quality of the accumulated image means, for example, determining whether the SNR (Signal-to-Noise Ratio: ratio of signal components to noise components) of the accumulated image satisfies a predetermined value. The control means 121 derives the SNR of the accumulated image, and compares the SNR with a predetermined value to determine whether the SNR of the accumulated image satisfies the predetermined value.

[0018] The display control means 122 controls the display means 114 to display a display based on the determination of the control means 121. Here, the display based on the determination is a display urging the user to end imaging, such as "Please stop radiation exposure," "Please stop the operation of the radiation imaging device," or "The examination image has been saved correctly," when the SNR of the accumulated image meets a predetermined value. The display urging the user to end imaging may also be a display such as "Please press the imaging end button," "The examination is completed," or "The SNR has reached a predetermined value." The display based on the determination may also be a numerical value of the SNR, such as "SNR: 70." The display based on the determination may also be a display such as "Please continue radiation exposure" or "The SNR has not reached a predetermined value," when the SNR of the accumulated image does not meet a predetermined value. The display control means 122 controls the display of at least one of these displays based on the determination regarding the image quality of the accumulated image. Note that these displays are examples of displays based on the determination regarding the image quality of the accumulated image.

[0019] The computer 120 further includes a storage unit 124 and a storage control unit 123. The storage unit 124 is, for example, a hard disk or a flash memory. The storage control unit 123 performs control such as storing the integrated image generated by the control unit 121 in the storage unit 124.

[0020] The exposure control unit, the receiving unit, and the signal processing unit may each be configured with a dedicated circuit, or may be configured with a combination of a general-purpose processing circuit and a memory circuit, similar to the control circuit 112. In one example, the exposure control device 130 has an exposure switch, and when the exposure switch is turned on by a user, it sends an exposure command to the radiation generation device 140 and also sends a start notification indicating the start of radiation irradiation to the computer 120. In response to the start notification, the computer 120 notifies the control circuit 112 of the radiation imaging device 110 of the start of radiation irradiation. Note that the control means 121 may be provided in the radiation imaging device 110 instead of the computer 120.

[0021] If the exposure control device 130 and the computer 120 are not synchronously connected, the radiation detection panel 111 continues the image readout operation and detects the start of radiation irradiation from the output value of the image signal.

[0022] The display means 114 is, for example, a liquid crystal monitor. The display means 114 is controlled by a display control means 122. The display means 114 displays a radiation image, an integrated image, various notifications to the operator (such as a notification to stop exposure), an SNR, etc. Here, the display means 114 may be separate from the computer 120, or may be included in the computer 120.

[0023] Next, the operation flow of the computer 120 will be described with reference to Fig. 2. Fig. 2 shows an example of a flow from acquisition of a radiographic image to displaying an exposure stop message on the display means 114. Here, the operation of the information processing system 100 is controlled by the computer 120. The operation of the radiation imaging device 110 is controlled by the control circuit 112 under the control of the computer 120. The operation shown in Fig. 2 is started, for example, together with the operation of the radiation imaging device 110. "Operation" in Fig. 2 indicates the operation of the computer 120.

[0024] When the operation starts, in S201, the control means 121 of the computer 120 acquires a radiographic image from the radiation imaging device 110. The acquired radiographic image is stored in the storage means 124 in the computer 120. At this time, the acquired radiographic image may be one image or multiple images captured consecutively.

[0025] Next, in S202, the computer 120 generates an accumulated image using the radiation image acquired in S201. Then, the display control means 122 included in the computer 120 controls the display of the generated accumulated image on the display means 114. The generated accumulated image is an example of a first accumulated image. The display control means 122 may display a plurality of continuously captured radiation images as a moving image, instead of the generated accumulated image. Displaying as a moving image refers to, for example, switching between and displaying a plurality of captured radiation images in the order they were captured at a predetermined interval (e.g., one second). The predetermined interval may be set arbitrarily or may be the imaging interval (frame rate). The display control means 122 may display both the accumulated image and the moving image.

[0026] Next, in S203, the computer 120 calculates the SNR of the accumulated image. The computer 120 calculates the SNR in a predetermined region of the accumulated image. Here, the predetermined region may be determined by selection by the operator. Alternatively, the computer 120 may determine the SNR by analyzing the accumulated image. The method of calculating the SNR is not particularly limited. For example, the computer 120 derives the amount of noise by subtracting two images obtained by capturing the same subject consecutively in time and dividing the result by the square root of 2. Here, it is preferable to use the two most recent radiographic images as the two images. Next, the computer 120 calculates the SNR by dividing the derived amount of noise from the signal amount of the accumulated image.

[0027] Next, in S204, the computer 120 compares the calculated SNR with a predetermined value. Here, the predetermined value is a value that provides the image quality required for the inspection image. The predetermined value is, for example, a numerical value such as "70," and is a value specified in, for example, the Japanese Industrial Standards (JIS Z 3110:2017). In this embodiment, the predetermined value is described as being set in advance in the computer 120, but the setting may also be changed by the operator. If the result of comparing the calculated SNR with the predetermined value is that the predetermined value is not exceeded (S204: NO), the computer 120 acquires a new radiographic image (S201). Next, the computer 120 generates a new accumulated image by integrating the acquired new radiographic image with the accumulated image (S202). Here, the computer 120 may integrate the acquired new radiographic image with the accumulated image, rather than integrating the acquired new radiographic image with the accumulated image. Furthermore, the computer 120 may perform accumulation each time a new radiographic image is acquired, or may acquire three new radiographic images in succession and accumulate only the third one. The new accumulated image is an example of a second accumulated image. The display control means 122 then controls the display of the new accumulated image on the display means 114. At this time, if there is an accumulated image already displayed, it is updated to the new accumulated image. The computer 120 then calculates the SNR of the new accumulated image (S203). The new accumulated image is then compared with a predetermined value (S204).

[0028] That is, if the SNR does not exceed the predetermined value (S204: NO), the computer 120 repeats the processes of S201 to S204 to repeatedly generate a new accumulated image. That is, if the SNR of the second accumulated image does not exceed the predetermined value, a new third accumulated image is generated from the second accumulated image. By repeatedly generating new accumulated images, an accumulated image obtained by accumulating more radiation images can be obtained. The more radiation images an accumulated image is, the higher its SNR will be.

[0029] If the result of comparing the calculated SNR with a predetermined value indicates that the SNR exceeds the predetermined value (S204: YES), the computer 120 determines that the integrated image satisfies the required image quality, and displays a message indicating that the predetermined value is satisfied (for example, a message urging the user to end image capture, as described above) on the display unit 114 (S205). Fig. 3 shows an example of a message urging the user to end image capture. Here, if a message indicating that the predetermined value is not satisfied has already been displayed before the message indicating that the predetermined value is satisfied is displayed, the computer 120 changes that message to a message indicating that the predetermined value is satisfied.

[0030] Next, the computer 120 stores the calculated SNR and the accumulated image in the storage means 124 within the computer 120 (S206). After storing, the computer 120 ends its operation. The storage means 124 is, for example, a hard disk or a flash memory.

[0031] The above is the operational flow of the computer 120 in the first embodiment.

[0032] By using the above-described operational flow, the operator can use the display means 114 to check whether the accumulated image satisfies the desired image quality during imaging. Therefore, the operator can stop the radiation exposure after confirming that the accumulated image satisfies the desired image quality. In other words, unlike the conventional method, there is no need to check whether the accumulated image satisfies the desired image quality after imaging is completed, which can reduce the need for reimaging.

[0033] 4, the display control means 122 included in the computer 120 may display the SNR of the accumulated image on the display means 114 in addition to a message such as "Please stop radiation exposure" that prompts the user to end the imaging. The SNR of the accumulated image may be displayed only when the SNR of the accumulated image is greater than a predetermined value (when the accumulated image satisfies the desired image quality), or may be displayed regardless of whether the SNR of the accumulated image is greater than or less than the predetermined value.

[0034] By displaying the SNR of the accumulated image regardless of whether it is greater or less than the predetermined value, the operator can constantly check the SNR of the accumulated image during imaging, and can therefore stop radiation exposure after confirming that the SNR of the radiographic image has reached the predetermined value.

[0035] Furthermore, the display control means 122 of the computer 120 may further display a graph 601 showing a transition of the SNR of the accumulated image on the display means 114, as shown in Fig. 6. The graph 601 is, for example, a graph with the number of frames on the horizontal axis and the SNR of the accumulated image on the vertical axis. By displaying the graph 601, the operator can grasp the time (remaining time) required for the SNR of the accumulated image to reach a predetermined value. Note that the horizontal axis of the graph 601 may be time. In other words, it is sufficient if the transition of the SNR of the accumulated image is shown. Therefore, for example, instead of the graph 601, a form may be used in which the SNR of the accumulated image and time are expressed in a tabular format.

[0036] 6, the display control means 122 of the computer 120 may further display on the display means 114 the time required for the SNR of the accumulated image to reach a predetermined value (remaining time 602). The control means 121 of the computer 120 calculates the remaining time 602 until the SNR of the accumulated image reaches a predetermined value based on the transition of the SNR of the accumulated image. Then, the display control means 122 further displays the calculated remaining time 602 on the display means 114. The method of calculating the remaining time 602 is, for example, to calculate the SNR of a new accumulated image when the new accumulated image is generated. Then, the calculated SNR is compared with the SNR of the accumulated image before the new accumulated image is generated to calculate the rate of change in the SNR of the accumulated image. Then, the remaining time 602 is calculated based on the calculated rate of change. Note that the display control means 122 may display the number of remaining shots to be taken on the display means 114 instead of the remaining time 602. That is, any mode may be used as long as it allows the operator to grasp the time (remaining time) required for the SNR of the accumulated image to reach a predetermined value.

[0037] Furthermore, the display control means 122 of the computer 120 may perform control to display a warning on the display means 114 when it is determined that the SNR of the accumulated image clearly does not reach a predetermined value. "Clearly does not reach a predetermined value" refers to, for example, when the SNR does not increase even when new accumulated images are repeatedly generated by repeating the processes of S201 to S204. In other words, this refers to when the rate of change in the SNR of the new accumulated image is smaller than a preset threshold value for the rate of change. The threshold value for the rate of change is set to, for example, "10%." When "10%" is set, for example, when SNR2 / SNR1, which is the ratio of SNR2 of the new accumulated image (second accumulated image) to SNR1 of the accumulated image immediately before the new accumulated image (first accumulated image), is less than 110%, a warning is displayed. Here, the threshold value for determining that "clearly does not reach a predetermined value" may be, for example, the numerical value of the SNR itself. In the case of the SNR value itself, for example, a warning is displayed when SNR2-SNR1, which is the difference between SNR2 of a new accumulated image (second accumulated image) and SNR1 of the accumulated image immediately before the new accumulated image (first accumulated image), is less than 3. Note that the above-mentioned "10%" and "less than 3" are examples of the first threshold value.

[0038] Alternatively, "clearly not reaching the predetermined value" may mean, for example, that the estimated remaining time is equal to or greater than a predetermined time (e.g., 30 minutes). The predetermined time may be set by the operator. This is because the time it takes for the SNR to reach the predetermined value may vary greatly depending on the test subject. The estimated remaining time is an example of time information. The predetermined time is also an example of a second threshold value.

[0039] Furthermore, the display control means 122 of the computer 120 may further display each of the radiation images used to generate the accumulated image on the display means 114, as shown in Fig. 6. Fig. 6 shows an example in which the three most recently acquired radiation images 603 are displayed.

[0040] Furthermore, the display control means 122 included in the computer 120 may further display the SNR of each of the radiation images used to generate the accumulated image on the display means 114. The display may be in the form of a graph or a table (list).

[0041] FIG. 5 shows the operational flow from when the computer 120 acquires a radiographic image to when the SNR of the radiographic image is displayed on the display means 114.

[0042] The computer 120 starts its operation by acquiring a radiation image (S201). Here, S201 in Fig. 5 and S201 in Fig. 2 are the same step.

[0043] Next, the computer 120 calculates the SNR of the radiation image (S501). The calculation method may be the same as that in S203 of FIG. 2 (calculating the SNR of the accumulated image).

[0044] Next, the computer 120 stores the radiation image and the SNR in the storage means 124 within the computer 120 (S502).

[0045] Next, the computer 120 displays the radiation image and the SNR on the display means 114 (S503).

[0046] After the radiation image and the SNR are displayed on the display means 114, the processes from S202 onward in FIG. 2 are carried out.

[0047] In this way, by displaying each radiation image used to generate an accumulated image and each SNR, the operator can confirm whether the radiation exposure is stable. This allows the operator to understand whether an accumulated image with the desired image quality can be obtained in the current imaging operation from the perspective of the stability of the radiation exposure. As a result, the operator can quickly determine whether re-imaging is necessary, enabling more effective examinations.

[0048] Furthermore, when the exposure control device 130 and the computer 120 are synchronized, the computer 120 may output a signal based on a determination regarding image quality. For example, the computer 120 may output an exposure stop signal to the exposure control device 130 when the SNR of the accumulated image exceeds a predetermined value. In this way, radiation exposure can be stopped without the intervention of an operator. The exposure stop signal is transmitted and received by communication between an output means (not shown) included in the computer 120 and the exposure control device 130. The output means may be, for example, an antenna for wireless communication or a LAN terminal for wired communication.

[0049] Furthermore, the display control means 122 of the computer 120 may display an integrated image 701 and an integrated image 702 obtained by shooting at a different time from the integrated image 701 side by side, as shown in FIG. 7 . FIG. 7 shows an example in which an integrated image 701 obtained by shooting on 2023 / 4 / 1 (present) and an integrated image 702 obtained by shooting on 2022 / 4 / 1 (past) are displayed side by side. The integrated image 702 is an example of a fourth integrated image. By displaying the integrated image 701 and the integrated image 702 side by side, the operator can easily compare the current integrated image with the past integrated image, making it easier to find, for example, a deteriorated portion. The display control means 122 may display three or more integrated images side by side.

[0050] Furthermore, the display control means 122 may not only display the accumulated image 701 and the accumulated image 702 side by side, but may also highlight and display the degraded parts detected by image processing, etc. Alternatively, it may display a difference image that highlights the difference between the two images.

[0051] FIG. 7 also shows an example in which integrated images (current integrated image 701 and past integrated image 702) of one area of ​​one subject are displayed side by side by capturing images at different times, but the present invention is not limited to this. For example, integrated images of multiple areas of one subject may be displayed side by side by capturing images at different times. FIG. 8 shows an example of non-destructive inspection of a pipe. FIG. 8 shows an example in which integrated image 801, integrated image 802, and integrated image 803, which were captured at different times, are displayed side by side. Here, integrated image 801 is an integrated image obtained by capturing image of area 1 (805) of pipe 804. Integrated image 802 is an integrated image obtained by capturing image of area 2 (806) of pipe 804. Integrated image 803 is an integrated image obtained by capturing image of area 3 (807) of pipe 804. Furthermore, the display control means 122 may display the accumulated images 801 to 803 taken at different times in a panoramic composite rather than displaying them side by side. By displaying the accumulated images in a panoramic composite, the operator can easily associate multiple regions of the subject with multiple accumulated images, enabling efficient inspection.

[0052] When performing panoramic composition, it is advisable to align the positions of the pipes included in each of the accumulated images 801 to 803 before performing panoramic composition. By performing panoramic composition after aligning the positions, the sense of incongruity in the image at the composite portion is reduced, allowing the operator to efficiently proceed with checking the inspection image. Furthermore, the accuracy of panoramic composition can be improved if adjacent accumulated images during panoramic composition include a common area. Therefore, the display control means 122 may display a message urging the operator to capture images so that the common area is included.

[0053] Furthermore, the display control means 122 may display an integrated image obtained by photographing the pipe from the front and an integrated image obtained by photographing the pipe from the back side side by side. In these cases, the display control means 122 may also display these integrated images by panoramic synthesis.
