[0002] Radiation imaging devices using flat panel detectors (FPDs) made of semiconductor materials are widely used as imaging devices for use in medical image diagnosis and non-destructive testing using radiation.

[0003] Generally, in radiography, the tube that irradiates the radiation must be selected according to the examination. However, Patent Document 1 describes a means for matching the imaging conditions with the tube, rather than manually selecting the tube that will irradiate during the examination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments will be described with reference to the drawings. Note that the configurations shown in the following embodiments are merely examples, and the present invention is not limited to the configurations shown in the drawings.

[0010] (First embodiment) Fig. 1 is a diagram showing an example of the basic configuration of a radiation imaging system according to this embodiment. The radiation imaging system 1 includes a control device 100, which is a radiation imaging control device, and at least one radiation detection device 130. In addition, Fig. 1 also includes a radiation generation device 120, an optical imaging device 140, a display unit 150, which is a display device, and an operation unit 160. The control device 100 controls radiation imaging using the radiation detection device 130 and the radiation generation device 120.

[0011] The radiation detection device 130 detects radiation that is irradiated from the radiation generation device 120 and passes through a subject (not shown, and may be referred to as a specimen hereinafter), and outputs image data corresponding to the radiation. The image data may also be referred to as a medical image or a radiological image. Specifically, the radiation detection device 130 detects the radiation that has passed through the subject as an electric charge corresponding to the amount of transmitted radiation. For example, the radiation detection device 130 may use a direct conversion sensor that directly converts radiation such as a-Se that converts radiation into an electric charge, or an indirect sensor that uses a scintillator such as CsI that converts radiation into visible light and a photoelectric conversion element such as a-Si. Furthermore, the radiation detection device 130 generates image data by A / D converting the detected electric charge, and outputs the image data to the control device 100.

[0012] The control device 100 is connected to the radiation generation device 120, the radiation detection device 130, and the optical imaging device 140, for example, via a wired or wireless network or a dedicated line. The control device 100 has an application function that runs on a computer. That is, the control device 100 has one or more processors and memories, and the processors execute programs stored in the memory to realize each of the functional units described below. However, some or all of the functional units may be realized by dedicated hardware.

[0013] The control device 100 controls the timing at which the radiation generating device 120 generates radiation and the radiation imaging conditions based on the examination information received by the operation unit 160. The radiation image acquisition unit 101 functions as a second acquisition unit, controls the timing at which the radiation detection device 130 captures and outputs image data, and receives the generated image data. The image processing unit 102 performs image processing on the received image data, and the image display control unit 104 displays the processed image on the display unit 150. A graphical user interface is provided using the display unit 150, and instructions from the operator are received by the operation unit 160. Examination information is selected based on the received input, and the examination information management unit 107 manages the information. In this way, the control device 100 is a control device that controls radiation imaging, and controls the operation of the radiation detection device 130 and the operation of the radiation generating device 120. Therefore, hereinafter, the control device 100 may also be referred to as a radiation imaging control device.

[0014] The control device 100 controls the conditions, timing, frame rate, etc., for the optical imaging device 140 to acquire the optical image. The optical image acquisition unit 103 functions as a first acquisition unit and acquires the optical image from the optical imaging device 140. The image display control unit 104 adds information to be displayed other than the optical image, and controls the contents to be displayed using the display unit 150, which is a display device. For example, as described in detail, the optical image analysis unit 105 analyzes the optical image acquired by the optical image acquisition unit, which is the first acquisition unit, and adds the result of the analysis to the optical image to be output to the display unit 150, which is a display device. In addition, the radiation image acquired by the radiation image acquisition unit 101 is output to the display unit 150, which is a display device, for display. The optical image analysis unit 105 analyzes the position, type, and posture of the human body part of the subject in the optical image acquired from the optical image acquisition unit 103. Then, it is determined whether the contents match the settings of the examination information acquired from the examination information management unit 107. The inference processing unit 106 using machine learning or the like may be used for the judgment of the optical image analysis unit 105. The image storage unit 108 stores the images acquired by the radiation image acquisition unit 101 and the optical image acquisition unit 103 .

[0015] The operation unit 160 is realized, for example, by displaying a plurality of pieces of acquired examination information in a list format on the display unit 150, and setting the selected examination information as the examination target in response to an operation input by a user to select one piece of examination information from the list. Note that the user may directly input examination information from the operation unit 160. In addition, after selecting an examination, an input to select the imaging content to be the imaging target is also accepted.

[0016] Fig. 2 is a diagram showing a radiation imaging system in this embodiment. In an environment in which the radiation imaging system is actually used, there may be a plurality of radiation generating devices 120, a plurality of radiation detecting devices 130, and a plurality of optical imaging devices 140. Fig. 2 shows an example in which there are two of each of the radiation generating devices 120, the radiation detecting devices 130, and the optical imaging devices 140, but the number of each device does not have to be two.

[0017] The radiation generating devices 120A and 120B each have identification information that allows them to be uniquely identified. Furthermore, the radiation detecting devices 130A and 130B each have identification information that allows them to be uniquely identified. Furthermore, the optical imaging devices 140A and 140B each have identification information that allows them to be uniquely identified. These pieces of identification information are managed by the control device 100. Furthermore, the optical imaging device 140A is attached to the radiation generating device 120A, and the optical imaging device 140B is attached to the radiation generating device 120B, and the attached information is also managed by the control device 100.

[0018] 3 is a diagram showing a detailed configuration of the optical image analysis unit 105 in this embodiment. The optical image analysis unit 105 is composed of a human body detection processing unit 300, a human body detection inference processing unit 301, an identification information acquisition unit 310, and an identification information acquisition inference processing unit 311 in addition to the inference processing unit 106.

[0019] The human body detection processing unit 300 performs human body detection processing to determine whether a subject is present in the optical image acquired from the optical image acquisition unit 103, in other words, to determine the presence or absence of a subject. The human body detection processing unit 300 performs human body detection processing, for example, by calculating a difference between frames and determining that a human body has been detected when a difference is present. The human body detection inference processing unit 301 may also realize the human body detection processing by performing inference processing using a learned model such as machine learning or deep learning. In this way, the human body detection processing unit 300 functions as a discrimination unit that discriminates the presence or absence of a subject. When the human body detection processing unit 300 detects a human body in the optical image, it notifies the control device 100. At this time, the control device 100 acquires identification information of the radiation generation device 120 attached to the optical imaging device 140 from the identification information of the optical imaging device 140 from which the optical image acquisition unit 103 acquired the optical image. For example, in the case of FIG. 2, a human body is detected by the optical imaging device 140A, and the control device 100 determines that the radiation generating device 120A is used for the examination because the optical imaging device 140A is attached to the radiation generating device 120A. The control device 100 controls the radiation generating device 120 of the acquired identification information so that it is in a state where it can irradiate. For example, when the control device 100 acquires the identification information of the radiation generating device 120A, the control device 100 sets the imaging conditions of the radiation generating device 120A, releases the irradiation lock, and controls it to a state where it can irradiate radiation when the operator presses an irradiation button (not shown). In this way, the control device 100, which is a radiation imaging control device, sets the radiation generating device used for radiation imaging in relation to radiation generation. Also, preferably, the control device 100 controls the radiation generating device other than the radiation generating device used for radiation imaging (the radiation generating device 120B in the case of FIG. 2) so that the setting related to radiation generation is not performed.

[0020] The identification information acquisition unit 310 acquires the identification information of the radiation detection device 130 in order to determine which radiation detection device 130 is present in the optical image acquired from the optical image acquisition unit 103. The identification information acquisition inference processing unit 311 may acquire the identification information by inference processing using a trained model such as machine learning or deep learning. In this way, the identification information acquisition unit 310 performs analysis related to the radiation detection device and determines the radiation detection device used for radiography. When the identification information acquisition unit 310 acquires the identification information of the radiation detection device 130, it notifies the control device 100. The control device 100 transmits a signal for transitioning the radiation detection device 130 used for the inspection to an imaging preparation state based on the identification information of the radiation detection device 130. For example, in the case of FIG. 2, it is determined that the radiation detection device 130A is present in the optical image, and the control device 100 transmits a signal for transitioning the radiation detection device 130A to an imaging preparation state. In this way, the control device 100, which is a radiography control device, performs settings related to radiation detection on the radiation detection device used for radiography.

[0021] Next, a switching process of the radiation generating device using the optical imaging device in this embodiment will be described with reference to the flowchart of FIG.

[0022] In S401, the human body detection processing unit 300 performs optical image analysis processing as shown in detail in FIG.

[0023] In S402, the control unit 100 determines whether the optical image analysis process in S401 has been completed for all connected optical photographing devices 140. If the optical image analysis process has been completed for all optical photographing devices, the process proceeds to S403, and if not, the process proceeds to S401.

[0024] In S403, the control unit 100 collects all the optical image analysis processing results, and checks whether any of the optical imaging devices 140 connected to the control device 100 has notified that a human body has been detected. Furthermore, the control unit 100 checks the identification information of the radiation detection devices 130 within the imaging range of the notified optical imaging device 140.

[0025] In S404, the control unit 100 judges from the result of S403 whether or not the number of optical photographing devices 140 that have detected a human body is one. If the number of optical photographing devices 140 that have detected a human body is one, the process proceeds to S406, and if the number is zero or two or more, the process proceeds to S405.

[0026] In S405, the control device 100 displays on the display unit 150 a list of the optical imaging devices 140 connected or a list of the optical imaging devices 140 that have been determined to have detected a human body, and prompts the operator to select an optical imaging device in which a subject is present within the imaging range via the operation unit 160. At this time, the possibility of a human body being present in each optical imaging device may be displayed as a probability of human body detection rate. Note that, instead of the possibility of a human body being present, the usability of the radiation generating device may be determined and displayed as a probability. In addition, a message notifying that automatic determination was not possible may be displayed in accordance with the optical imaging device list, and similarly, a display may be displayed indicating that the radiation generating device to be used cannot be determined. Furthermore, optical images acquired from all the optical imaging devices 140 in the optical imaging device list may be displayed in accordance with the optical imaging device list. The display contents are controlled by the image display control unit 104 described above and output to the display unit 150. In this way, the image display control unit 104 can output the result of determination by the optical image analysis unit 105 functioning as a determination unit to the display unit 150, which is a display device.

[0027] In S406, the control unit 100 acquires the identification information of the optical photographing device 140 that detected the human body or the optical photographing device 140 selected in S405.

[0028] In S407, the control device 100 transmits a signal to the radiation detection device 130 to transition to a preparation state based on the identification information of the radiation detection device 130 acquired in S403. For example, if the radiation detection device 130 confirmed in S403 is the radiation detection device 130A, the radiation detection device 130A controls the bias power supply using a main control circuit to apply a bias voltage to the two-dimensional imaging element. Thereafter, in order to read out dark current signals accumulated in the pixels, initialization is performed in which an image signal is read from the pixel array by a drive circuit. After completion of the initialization, the radiation detection device 130A transmits state information to the control device 100 indicating that the radiation detection device 130A is in a preparation state for obtaining a radiation image.

[0029] In S408, the control device 100 acquires the identification information of the radiation generation device 120 corresponding to the identification information of the optical imaging device 140 acquired in S406.

[0030] In S409, the control device controls the radiation generation device 120 corresponding to the identification information acquired in S408 so that the radiation generation device 120 is ready for irradiation.

[0031] In S410 , the image display control unit 104 acquires the optical image of the optical photographing device 140 determined in S406 from the optical image acquisition unit 103 , and displays it on the display unit 150 .

[0032] Next, the analysis process of the optical images acquired from each optical photographing device 140 in this embodiment will be described with reference to the flowchart in FIG.

[0033] In S501, the optical image acquisition unit 103 acquires an optical image from a connected optical imaging device. For example, when analyzing an optical image of the optical imaging device 140A, the optical image acquisition unit 103 acquires an optical image from the optical imaging device 140A. The following steps will be described taking the case of analyzing the optical image of the optical imaging device 140A as an example.

[0034] In S502, the human body detection processing unit 300 performs human body detection processing on the optical image acquired in S501 from the optical imaging device 140. The human body detection processing uses, for example, image processing that calculates a difference between frames of the optical image and determines that a human body is present when a difference is found. The human body detection processing may also be inference processing using machine learning or a trained model such as machine learning or deep learning, using the inference processing unit 106.

[0035] In S503, the human body detection processing unit 300 determines whether or not a human body has been detected based on the processing result in S502. If a human body has been detected, the process proceeds to S504, and if not, the analysis process ends.

[0036] In S504 , the control device 100 acquires the identification information of the optical photographing device 140 .

[0037] In S505, the identification information acquisition unit 310 performs an analysis process on the optical image acquired from the optical image acquisition unit 103, and identifies the radiation detection device 130 within the imaging range of the optical imaging device 140. For example, a barcode is attached to the radiation detection device 130A, and by reading the barcode in the analysis process, it is identified that the radiation detection device 130A is within the imaging range of the optical device 140A.

[0038] As described above, according to this embodiment, the radiation generator to be used for the examination can be automatically determined by determining whether a subject is within the imaging range of the optical imaging device through image analysis processing of the optical imaging device. This makes it possible to automatically switch the radiation generator according to the actual examination room and the condition of the subject, thereby improving convenience.

[0039] In this embodiment, the human body detection process is performed using an optical image acquired from an optical imaging device, but this is merely an example. Any sensor capable of detecting a human body may be used, and the sensor for detecting a human body is not limited to an optical imaging device. For example, an infrared sensor may be used to detect a human body based on changes in distance information. In addition, a sensor such as an ultrasonic sensor or a thermal sensor may be used to detect a human body. The presence or absence of a subject may be detected and determined by detecting information attached to the human body (for example, an IC tag is attached to the subject and information on the tag is detected). Furthermore, the sensor used for detecting a human body may be a single sensor, or a combination of multiple types of sensors may be used.

[0040] In the above embodiment, the radiation imaging system having a plurality of radiation detection devices (130A, 130B) as shown in FIG. 2 has been described, but the present invention is not limited to this. For example, there may be a case where there is only one radiation detection device. For example, in the system shown in FIG. 2, when there is only the radiation detection device 130B (when there is no radiation detection device 130A), the image display control unit 104 may output to the display unit 150 a warning that imaging by the radiation generation device 120A cannot be performed. In this case, the subject is identified in the optical image captured by the optical imaging device 140A, but the radiation detection device is not identified in the image. Therefore, by taking these two analysis results into consideration, the image display control unit 104 outputs to the display unit 150 information (for example, a warning) indicating that the radiation generation device used for radiation imaging cannot be identified, and displays it, the occurrence of invalid imaging can be suppressed. In this way, it is more preferable to identify the radiation generation device used for radiation imaging using the analysis result of the presence or absence of the subject and the analysis result regarding the radiation detection device. In addition, even in this way, when the number of radiation detection devices is small relative to the number of radiation generation devices, for example, when there is only one radiation detection device for multiple radiation generation devices, the present technology is applicable and provides the above-mentioned effects.

[0041] Second embodiment In the second embodiment, differences from the first embodiment will be described.

[0042] 6 is a diagram showing an example of the configuration of a radiation imaging system in this embodiment. The radiation imaging system includes a control device 100, radiation generation devices 120A and 120B, radiation detection devices 130A and 130B, an optical imaging device 140, a display unit 150, and an operation unit 160.

[0043] The optical imaging device 140 always captures an image of the entire examination room including the radiation system, such as the subject, the radiation generating devices 120A and 120B, and the radiation detecting devices 130A and 130B. That is, unlike the first embodiment in which the optical imaging device and the radiation generating device are associated with each other, the optical imaging device 140 captures an image of the entire examination room. The optical imaging device 140 is connected to the control device 100, for example, via a wired or wireless network or a dedicated line. The optical image analysis unit 105 identifies the positions and device orientations of the subject, the radiation generating device 120, and the radiation detecting device 130. The optical image analysis unit 105 may use inference processing using a trained model such as machine learning or deep learning to identify the positions and device orientations.

[0044] The control device 100 determines which of the connected radiation generation devices 120 is to be used in the examination based on the analysis result of the optical image analysis unit 105. For example, the control device 100 determines that the radiation generation device 120A is to be used in the examination based on the position / apparatus orientation information of the radiation generation device 120A and the position information of the subject.

[0045] Next, a switching process of the radiation imaging device using the optical imaging device 140 in this embodiment will be described with reference to the flowchart of FIG.

[0046] In S701, the optical image analysis unit 105 performs optical image analysis processing as shown in detail in FIG.

[0047] In S702, the control device 100 determines whether or not a subject and a radiation detection device 130 are present at the irradiation destination of the radiation generation device 120 based on the analysis result of S701, and determines whether or not the test preparation is complete. For example, if it is determined from the analysis result of S701 that a subject is present at the irradiation destination of the radiation generation device 120 but a radiation detection device 130 is not present, it determines that the test preparation is not complete. If the test preparation is complete, the process proceeds to S703, and if the test preparation is not complete, the process may be terminated or a warning may be displayed on the display unit 150 to the effect that a radiation detection device is not provided.

[0048] In S703, the control device 100 transmits a signal to the radiation detection device 130 to transition to a preparation state based on the identification information of the radiation detection device 130 acquired in S701. For example, if the radiation detection device confirmed in S701 is the radiation detection device 130A, the radiation detection device 130A controls the bias power supply by the main control circuit to apply a bias voltage to the two-dimensional imaging element. Thereafter, in order to read out dark current signals accumulated in the pixels, initialization is performed in which an image signal is read out from the pixel array by the drive circuit. After completion of the initialization, the radiation detection device 130A transmits state information to the control device 100 indicating that the radiation detection device 130A is in a preparation state for obtaining a radiation image.

[0049] In S704, the control device 100 controls the radiation generating device 120, which has been determined to be ready for inspection in S702, so that it is in a state where it can irradiate radiation. For example, when it is determined that an inspection is to be performed using the radiation generating device 120A, the control device 100 sets the imaging conditions of the radiation generating device 120A, releases the irradiation lock, and controls it to a state where it can irradiate radiation when the operator presses an irradiation button (not shown).

[0050] Next, the analysis process of the optical image acquired from the optical photographing device 140 in this embodiment will be described with reference to the flowchart in FIG.

[0051] In S801, the optical image acquisition unit 103 acquires an optical image from the optical photographing device 140.

[0052] In S802, the optical image analysis unit 105 analyzes the position of the radiation generating device within the imaging range and the orientation of the device using the optical image acquired in S801. Furthermore, the optical image analysis unit 105 acquires identification information of the radiation generating device within the imaging range. The position / orientation analysis and acquisition of the identification information of the radiation generating device may be performed using inference processing using a trained model such as machine learning or deep learning.

[0053] In S803, the optical image analysis unit 105 uses the optical image acquired in S801 to analyze the position of the radiation detection device within the imaging range and the orientation of the device. Furthermore, the optical image analysis unit 105 acquires identification information of the radiation detection device within the imaging range. The position / orientation analysis and acquisition of the identification information of the radiation detection device may be performed using inference processing using a trained model such as machine learning or deep learning.

[0054] In S804, the optical image analysis unit 105 analyzes the position of the subject within the imaging range using the optical image acquired in S801. The subject's position analysis may be performed using, for example, inference processing using a trained model such as machine learning or deep learning.

[0055] In S805, the optical image analysis unit 105 notifies the control device 100 of the results of the analysis performed in S802 to S804.

[0056] As described above, according to this embodiment, the radiation generator to be used can be automatically determined from the position and orientation information of various devices in the examination room and the position information of the subject, based on the image analysis process of the optical imaging device that captures the entire examination room. This makes it possible to automatically switch the radiation generator according to the actual examination room and the condition of the subject, thereby improving convenience.

[0057] In this embodiment, the position of the subject and the position and orientation of each device are detected using the optical image acquired from the optical imaging device 140, but this is merely an example. Any sensor capable of detecting the position and orientation may be used, and is not limited to the optical imaging device. Furthermore, a single sensor may be used, or multiple types of sensors may be combined. For example, the position information of the subject and each device may be acquired from RFID, and the orientation information of each device may be acquired using an acceleration sensor.

[0058] Furthermore, in order to improve the accuracy of determining the radiation generating device to be used, the optical imaging device described in this embodiment may be combined with the human body detection sensor described in the first embodiment. For example, position information of the subject and each device, and orientation information of each device, which can be obtained from an optical image of the optical imaging device that captures the entire examination room, and human body detection information, which can be obtained from the optical imaging device attached to the radiation generating device, may be analyzed in a composite manner.
