Description

Technical Field

[0001] The present invention relates to a radiographic device and a radiographic system. Background Art

[0002] In medical settings, radiographic imaging is commonly performed using a radiographic system. In the process of radiographic imaging, imaging may fail (referred to as imaging error) due to incorrect patient positioning, patient body movement or insufficient breathing, incorrect imaging condition settings, or foreign body detection.

[0003] The radiographic engineer checks the radiographic images obtained by shooting, thereby determining whether there is a shooting error. When the radiographic engineer determines that there is a shooting error, the radiographic engineer performs another shooting to obtain the radiographic images required for diagnosis. Furthermore, even if the radiographic engineer does not determine that there is a shooting error, the doctor may sometimes determine that the radiographic image is not suitable for examination.

[0004] In this way, when judging a shooting error, if the judgment criterion of a shooting error performed by the photography engineer is different from the judgment criterion of a shooting error performed by the doctor who uses the radiographic image for diagnosis, the labor and time required for re-shooting and re-examination will increase, and unnecessary re-shooting will be performed because a radiographic image that does not need to be marked as a shooting error will be marked as a shooting error, which may be undesirable from the perspective of exposure to radiation.

[0005] Therefore, by judging photographing errors according to a predetermined standard, unnecessary photographing errors can be reduced, and re-examinations after the examination can be reduced. As a result, work efficiency can be expected for medical facilities, and unnecessary exposure or re-examination can be expected to be reduced for examinees.

[0006] Regarding judging shooting errors based on a predetermined standard, the following radiographic system is disclosed: In a specific radiographic system, image degradation caused by positional variation is detected by performing regression analysis (Patent Document 1). Also, regarding achieving work efficiency of re-inspection, the following radiographic control device is disclosed: In split radiography, re-shooting can be performed without resetting radiographic conditions (Patent Document 2).

[0011] Technical issues to be solved by the invention

[0012] When it is determined that there is a shooting error, reshooting is performed afterwards, but there is still a possibility of shooting error in the reshooting. When a shooting error occurs in the reshooting, the reshooting is repeated again, which increases the number of examinations and the exposure to radiation, which is not preferable. Therefore, it is desired to suppress the occurrence of shooting errors in the reshooting in addition to judging shooting errors based on a predetermined standard.

[0013] An object of the present invention is to provide a radiographic apparatus and a radiographic system that judge an imaging error based on a predetermined criterion and present a suggestion for reducing the number of re-imaging operations.

[0052] like Figure 1As shown, an X-ray imaging system 10 (radiation imaging device) using X-rays as radiation includes an X-ray generator (radiation generator) 11 and an X-ray imaging device 12. The X-ray generator 11 is composed of an X-ray source (radiation source) 13 and a radiation source control device 14. The radiation source generates radiation. The X-ray imaging device 12 is composed of an X-ray detection panel (radiation imaging unit) 15 and a console 16.

[0053] In addition, the X-ray imaging system 10 is also provided with an irradiation switch for instructing the start of radiation irradiation, a standing imaging table for imaging the subject Obj in a standing posture, or a lying imaging table for imaging the subject Obj in a lying posture, etc. Figure 1 , a state is shown in which a subject Obj stands at a position facing the X-ray source 13 in the imaging room where the X-ray imaging system 10 is installed, and the subject Obj is imaged in a standing posture.

[0054] In addition, the X-ray imaging system 10 includes, for example, an imaging error management device for managing the imaged information, etc. In addition, the system is connected to an image server such as a PACS (Picture Archiving and Communication System for medical application) for managing the imaged X-ray images and information related to the X-ray images, and an information management server such as a HIS (Hospital Information System) or a RIS (Radiology Information System) for logging in and managing patient information, medical information, examination information, accounting information, and imaging orders for each patient.

[0055] The X-ray source 13 includes an X-ray tube that generates X-rays Ra, an irradiation field limiter that limits the area irradiated by the X-rays Ra, i.e., the irradiation field, and an irradiation field display light source that emits irradiation field display light that indicates the irradiation field. In order to confirm the position of the object Obj, etc., an optical camera may be installed in the X-ray source 13.

[0056] The X-ray source control device 14 includes a touch panel, a voltage generating unit, a control unit, and an irradiation switch. The touch panel is operated to set the irradiation conditions of the X-ray Ra consisting of the tube voltage and tube current applied to the X-ray tube and the irradiation time of the X-ray Ra, and the size of the irradiation opening of the irradiation field limiter.

[0057] The voltage generating unit generates a tube voltage applied to the X-ray tube. The control unit controls the tube voltage, tube current, and irradiation time of the X-ray Ra by controlling the operation of the voltage generating unit. The control unit has a timer that starts timing when the X-ray tube generates the X-ray Ra, and stops the operation of the X-ray tube when the time counted by the timer reaches the irradiation time set under the irradiation conditions. In addition, the control unit activates the irradiation field limiter and sets the size of its irradiation opening to the size set by the touch panel.

[0058] When the X-ray Ra is to be irradiated, the user of the X-ray imaging device, i.e., the operator such as the imaging engineer, operates the irradiation switch. The irradiation switch is a two-stage push-type. When the irradiation switch is pressed to the first stage (half-pressed), the control unit starts the preparatory action before the X-ray Ra is generated in the X-ray tube. When the irradiation switch is pressed to the second stage (full press), the control unit generates the X-ray Ra in the X-ray tube. Thus, the X-ray Ra is irradiated toward the imaging part of the object Obj.

[0059] The X-ray detection panel 15 detects the X-ray Ra emitted from the X-ray source 13 and transmitted through the object Obj for each pixel, and sets it as an X-ray image 30. The X-ray detection panel 15 has a wireless communication unit and a battery, and operates wirelessly. The X-ray detection panel 15 wirelessly transmits the X-ray image 30 to the console 16. In addition, the X-ray detection panel 15 can also communicate by wire.

[0060] The console 16 is based on a computer such as a notebook personal computer, and is configured by installing a control program such as an operating system or various application programs. The console 16 has a display 17 and an input device 18 such as a touch panel and a keyboard. The display 17 displays the radiographic image obtained by imaging. The console 16 displays various operation screens having an operation function based on a GUI (Graphical User Interface) on the display 17, and receives input of various operation instructions from an operator of the input device 18 through the various operation screens.

[0061] Console 16 receives Figure 2 The radiography order 21 is input as shown. The radiography order 21 is information for instructing an operator to perform X-ray radiography from a radiography requester such as a doctor in a medical department, for example. The radiography order 21 is transmitted from the RIS to the console 16, for example.

[0062] The photography command 21 includes items such as a command ID (Identification Data), a subject ID, and a photography method. The command ID is a symbol or number for identifying each photography command 21, and is automatically assigned by the RIS. The subject ID of the subject Obj to be photographed is recorded in the subject ID item. The subject ID is a symbol or number for identifying each subject Obj.

[0063] The photographic technique is the photographic part of the object Obj and the information related to the posture and direction of the photographic part. The photographic part includes the knee, head, cervical spine, chest, abdomen, hand, finger or elbow. The posture is the posture of the object Obj such as standing, lying or sitting, and the direction is the direction of the object Obj relative to the X-ray source 13 such as the front, side or back. Although omitted in the figure, in addition to these items, the photographic order 21 also includes items of subject information such as the name, gender, age, height or weight of the subject Obj. In addition, the photographic order 21 also includes items such as the medical department to which the photographic client belongs, the ID of the photographic client, the date and time of receiving the photographic order 21 through the RIS, the purpose of the photographic purpose such as regular observation after surgery or the effect determination of the therapeutic drug, or the notification matters of the photographic client to the operator.

[0064] The console 16 stores Figure 3 The menu / condition table 22 shown in FIG. 2 is a menu / condition table 22 in which a photographic menu that specifies a photographic method that is a group of a photographic part, a posture, and a direction is associated with an irradiation condition corresponding thereto and registered. The group of the photographic menu and the irradiation condition includes not only items registered by default but also items that are edited by the operator in the default group or newly added to the default group. In addition, the photographic menu may be a photographic menu that specifies only the photographic part, not the photographic method.

[0065] The console 16 is operated by the operator to Figure 2 The imaging order list in which the contents of the imaging order 21 are tabulated is displayed on the display 17. The operator checks the imaging order list to confirm the contents of the imaging order 21. Next, the console 16 sets the imaging menu in a manner that allows the imaging menu to be set. Figure 3 The contents of the menu / condition table 22 are displayed on the display 17. The operator selects a photography menu that matches the photography method designated by the photography command 21 and performs settings.

[0066] The console 16 wirelessly transmits a condition setting signal including various information such as an imaging menu set by an operator and irradiation conditions corresponding to the set imaging menu, a command ID, or a console ID of a symbol or number for identifying itself to the X-ray detection panel 15 .

[0067] After setting the imaging conditions, the operator positions the X-ray source 13, the X-ray detection panel 15, and the object Obj at the desired positions, and then drives the X-ray source 13 to irradiate the object Obj with X-rays Ra. The X-rays Ra that have passed through the object Obj are irradiated to the X-ray detection panel 15, and an X-ray image 30 is detected by the X-ray detection panel 15.

[0068] like Figure 4 As shown, the X-ray detection panel 15 sends the X-ray image 30 to the console 16. The console 16 displays the X-ray image 30 on the display 17, thereby showing it to the operator. Figure 4 In FIG. 3 , the imaging part in the X-ray image 30 is the knee.

[0069] The console 16 sets the X-ray image 30 to conform to, for example, Figure 5 The image file 31 is formatted in accordance with the DICOM (Digital Imaging and Communication in Medicine) standard as shown in the figure and sent to the PACS.

[0070] The image file 31 is a file in which an X-ray image 30 and supplementary information 32 are associated with each other through an image ID. The supplementary information 32 includes subject information, order ID, radiography menu, irradiation conditions, etc. The radiography client accesses the PACS using a client terminal to download the image file 31, thereby enabling the X-ray image 30 to be viewed through the client terminal.

[0071] exist Figure 6 In the embodiment, the console 16 includes a storage device 41 , a memory 42 , a CPU (Central Processing Unit) 43 , and a communication unit 44 in addition to the display 17 and the input device 18 described above. These are connected to each other via a data bus 45 .

[0072] The storage device 41 is a hard disk drive or a hard disk array having multiple hard disk drives built into the console 16 or connected via a cable or a network. The storage device 41 stores control programs such as an operating system, various application programs, and various data accompanying these programs.

[0073] The memory 42 is a working memory used by the CPU 43 to execute processing. The CPU 43 loads the program stored in the storage device 41 into the memory 42 and executes processing according to the program, thereby centrally controlling each part of the console 16. The communication unit 44 has a function of communicating with other devices or networks, for example, it is responsible for the communication of various data such as the X-ray image 30 between the X-ray detection panel 15.

[0074] exist Figure 7 In the storage device 41, a work program 51 and a shooting error reason database (hereinafter referred to as DB (Database)) 52 are stored. The shooting error reason DB 52 will be described later. Figure 3 The menu / condition table 22 shown in FIG. 2 is also stored in the storage device 41 .

[0075] When the operation program 51 is started, the CPU 43 and the memory 42 work together to function as an image acquisition unit 61, an image processing unit 62, a display instruction receiving unit 63, and a display control unit 64. Therefore, the X-ray imaging device 12 includes an image acquisition unit 61, an image processing unit 62, a display instruction receiving unit 63, and a display control unit 64. The image acquisition unit 61 acquires images such as the X-ray image 30 received by the communication unit 44 for analysis. Usually, the image acquisition unit 61 acquires all X-ray images 30 obtained by imaging and sends them to the image processing unit 62 respectively.

[0076] like Figure 8 As shown, the image processing unit 62 includes a shooting error determination unit 71, a shooting error reason determination unit 73a, and a correction information determination unit 74. The shooting error determination unit 71 includes a learning completed model 72a and a determination image adjustment unit 72b. The image processing unit 62 analyzes the X-ray image 30 sent from the image acquisition unit 61. The analysis is performed for the purpose of determining whether the shooting has failed and determining information related to the reason for the shooting failure, that is, the shooting error reason. Therefore, the image processing unit 62 analyzes the X-ray image 30, sets the radiological image determined as a shooting failure as a shooting error, and determines the reason for the determination, that is, the shooting error reason and the correction information for eliminating the shooting error reason.

[0077] The image processing unit 62 learns X-ray images acquired in the past in advance, and uses the learned model 72a to determine whether the X-ray image 30 has failed to be captured. Through this determination, information on whether the imaging has failed and information on the reason for the imaging failure are output.

[0078] By using the learned model 72a, it is possible to make a judgment based on a prescribed benchmark. Furthermore, the judgment result can be obtained in a short time. The learned model 72a can use, for example, an algorithm or a program library that has a good judgment result for image processing. Furthermore, an algorithm or a program library that has a good judgment result for X-ray images can also be constructed and used. In addition, as learning data, data that at least gives information about whether an X-ray image acquired in the past is a shooting error can be used in advance. In addition, data that gives any of the accompanying information related to the X-ray image, such as photographic data or patient data, to the X-ray image can also be used. Furthermore, data that selects a feature quantity based on the type of the X-ray image and gives feature quantity information to the X-ray image can also be used.

[0079] As long as the judgment can be made according to the prescribed criteria, other well-known machine learning techniques or image processing techniques other than machine learning techniques may be used in addition to the learned model 72a. In addition, there may be multiple image processing techniques other than the learned model 72a and the machine learning technique, and the preferred technique may be selected and used according to the type of the part of the X-ray image 30 or the accuracy of the judgment result.

[0080] The judgment criterion is set in advance. For example, the criterion is set strictly or loosely according to the purpose of the X-ray image 30. More specifically, for example, when judging whether the X-ray image 30 is successfully photographed relative to the photography menu, a threshold is set in advance for the deviation of the depiction of the key part. By further reducing the threshold, the criterion can be set strictly. On the other hand, by further increasing the threshold, the criterion can be set loosely. Therefore, the desired judgment criterion can be set according to the medical institution. Moreover, even within the same medical institution, the judgment criterion can be set differently according to each medical department such as the emergency department, internal medicine or surgery, or even in the same internal medicine department, according to each photography area, or for the purpose of training operators on the judgment criterion for photography errors, etc., according to each purpose, etc.

[0081] Furthermore, the setting of the judgment standard can also be changed. The setting change can be performed through the input device 18 or the like. Furthermore, the image processing unit 62 can also change the setting by feeding back the instruction from the operator or the like by the display instruction receiving unit 63 or the approval receiving unit 81 or the like described later. In addition, the setting unit (not shown) provided in the image processing unit 62 sets the judgment standard or changes the setting of the judgment standard. The setting unit has the function of performing various settings related to the image processing unit 62.

[0082] In addition, the learned model 72a determines whether the X-ray image 30 has failed to be captured, and can therefore distinguish between images with failed capture and images without failed capture. Therefore, it is possible to determine whether the capture has not failed, that is, whether the capture has been successful.

[0083] The judgment image adjustment unit 72b adjusts the X-ray image 30 before making a judgment. The adjustment is performed for the purpose of improving the accuracy of the judgment. Therefore, as the content of the adjustment, for example, cropping of a part of the image in the X-ray image 30 as the area to be judged, deletion of unnecessary areas in the image, and / or adjustment of brightness or chroma, etc. can be cited. In particular, when using a learned model 72a using deep learning, etc., in the X-ray image 30, sometimes an image area that is not related to the judgment is misclassified, etc., so that an accurate analysis result cannot be obtained. It is preferable to avoid this situation. Therefore, in the adjustment of the X-ray image 30, it is preferable to pre-crop the area to be judged in the image specified by the operator, etc., so as to perform a more accurate analysis of the area to be judged. In addition, sometimes no adjustment is performed.

[0084] like Fig. 9 As shown, when performing cropping-based adjustment, the adjustment is performed by selecting the area to be determined in the X-ray image 30 displayed on the display 17 using a frame 85. The frame 85 is, for example, a rectangular frame, and can be set to include the area to be determined automatically based on the image recognition technology, or can be set by the operator dragging the area designation cursor 86 on the X-ray image 30 to adjust the size of the frame 85, that is, adjust the area to be determined in the X-ray image 30. The determined image adjustment unit 72b can perform cropping-based adjustment on the X-ray image 30 by selecting the area to be determined using the frame 85, for example, to perform the above-mentioned adjustment with higher accuracy. Fig. 9 Determination of shooting error of the knee joint as shown.

[0085] The shooting error reason determination unit 73a determines the shooting error reason based on the information output by the learning model 72a during the determination. The shooting error reason determination unit 73a includes a deviation measurement unit 73b. The information output by the learning model 72a during the determination is information related to the reason determined by the learning model 72a as the shooting failure. For example, the patient's positioning error, the patient's body movement or insufficient breathing, the setting error of the shooting conditions, or the detection of foreign objects such as a heating bag or a necklace can be cited.

[0086] In addition to the information items related to the reasons for the failure of shooting, the reasons for shooting errors may also include information related to the items. For example, the reasons for shooting errors include items where there is a positioning error of the patient and information about which part of the position deviates and to what extent. The deviation measurement unit 73b outputs information about the part where there is deviation and the amount of deviation based on the information output by the learned model 72a and the image analysis technology of the X-ray image 30 determined to be a shooting error. In addition, the reasons for shooting errors may include explanations of the failed parts and the non-failed parts. Therefore, the reasons for shooting errors may include information related to the parts determined to be shooting failures and information related to the parts determined to be shooting successes. For example, in the positioning error of the patient, the angle of knee flexion in the patient's height direction is accurate but the internal rotation of the knee is insufficient, etc. can be set as detailed reasons for shooting errors.

[0087] The correction information is information indicating a suggestion for reducing the number of re-photographing. Therefore, the correction information is information indicating a suggestion for making the photography successful by re-photographing (preferably once). The correction information is a past X-ray image of the same portion and photography data as the X-ray image 30 set as a photography error, and is information comparing a sample image when the photography is successful with the X-ray image 30 set as a photography error. As described above, the photography error reason and / or the correction information include a suggestion for reducing the number of re-photographing.

[0088] The correction information determination unit 74 determines the correction information for eliminating the shooting error reason determined by the shooting error reason determination unit 73a by accessing the shooting error reason DB 52. The shooting error reason DB 52 is a database that associates and stores the shooting error reason with the correction information for the shooting error reason. For example, more specifically, the shooting error reason DB 52 includes a shooting error reason / correction information table 52a.

[0089] In the shooting error reason / correction information table 52a, the shooting error reason and the correction information for the shooting error reason are recorded in a corresponding association. For example, in the case of a knee joint side view with the shooting menu being "knee / bent posture / side" (reference Figure 5 ), the successfully photographed X-ray image 30a is set as "the articular surfaces of the medial femoral condyle and the lateral femoral condyle are roughly consistent" (Ogawa Keiju, "New Illustrated Simple X-ray Photography Method", 2nd edition, Kanehara Publishing Co., Ltd., February 2012, p137). Therefore, regarding the reasons for photographing errors and correction information, for example, when the articular surfaces of the medial femoral condyle and the lateral femoral condyle are inconsistent, the reasons for photographing errors are determined based on the shape and size of their deviations. In addition, in order to correct their deviations to the desired position for photographing, the degree to which the subject Obj is tilted is preferably used as correction information.

[0090] The shooting error reason / correction information table 52a is further described in detail. Fig.10 As shown in the figure, when an X-ray image 30b in which the medial condyle 75b of the femur and the lateral condyle 75a are inconsistent is obtained, the image processing unit 62 analyzes the X-ray image 30b and, based on the contour of the medial condyle 75b of the femur and the contour of the lateral condyle 75a, for example, identifies that the distance between them exceeds a set threshold. Therefore, the image processing unit 62 sets the X-ray image 30b as a shooting error in which the knee joint lateral image shooting fails. In addition, in the X-ray image 30a in which the shooting is successful, the contour of the medial condyle 75b of the femur is consistent with the contour of the lateral condyle 75a. Moreover, based on the position of the contour of the medial condyle 75b of the femur and the contour of the lateral condyle 75a, the shooting error reason is determined as "it is believed that the deviation of the inner and outer condyle edges is large." According to the shooting error reason / correction information table 52a, the correction information for the shooting error reason is "perhaps it is better to slightly rotate inward." In this way, the shooting error reason and correction information of the X-ray image 30 are determined.

[0091] When the correction information is displayed, the operator can perform another shot after checking the correction information. For example, in the re-shooting of the X-ray image 30b, the following suggestion is displayed regarding the inclination of the thigh relative to the irradiation plane of the X-ray Ra: slightly tilt the body away from the irradiation plane of the X-ray Ra by, for example, about 10 degrees, and do not change anything else, and the shooting is successful.

[0092] More specifically, the correction information may be any information other than text, such as a static image, a dynamic image, an illustration, an icon, or an animation, as long as it can show information including suggestions for the operator to successfully re-photograph during re-photographing. When using images such as a static image, a dynamic image, an illustration, an icon, or an animation, the correction information preferably includes an image: a sample image of a past X-ray image of the same part and / or the same imaging data and when the X-ray image 30 is assumed to be a photographing error, and when the photographing is successful. Furthermore, the sample image may be processed to display a part to be changed.

[0093] Furthermore, the correction information may include the X-ray image 30b that was photographed incorrectly. Furthermore, it may be information combining them. More specifically, for example, it may be an image in which a portion of the position of the subject Obj or an arrow indicating the tilt direction, etc. is overlapped on a portion of the area on the X-ray image 30b that was photographed incorrectly. Furthermore, it may be an image in which the X-ray image 30b that was photographed incorrectly and the X-ray image 30a of the same portion that was photographed successfully are arranged. Alternatively, in the case of an animation or a dynamic image, for example, it may be an animation in the following manner: based on the image of the subject Obj on the X-ray image 30b that was photographed incorrectly and the image of the subject Obj on the X-ray image 30a when the photographing was successful, the deviated line on the X-ray image 30b that was photographed incorrectly is slowly moved in a manner consistent with the corresponding line on the X-ray image 30a when the photographing was successful.

[0094] like Fig.11 As shown, for example, when the X-ray image 30 is displayed on the display 17, the information on the part with deviation and the amount of deviation based on the deviation measuring unit 73b is output by displaying the deviation amount information 87 in a superimposed manner. The deviation amount information 87 numerically displays the deviation amount of the part with the largest deviation amount among the parts with deviation, and represents the deviation amount with a numerical value such as "5mm", and represents the part where the numerical value is measured with an arrow or the like. Thus, the operator can more accurately recognize the degree of internal rotation required for successful imaging. In addition, the deviation amount information 87 can be set not to be displayed according to the situation.

[0095] The display control unit 64 controls the display 17 to display the determined correction information. The operator confirms the correction information displayed on the display 17 of the console 16 and then performs the photography again, thereby reducing the possibility of another photography error.

[0096] As described above, the X-ray imaging system 10 determines imaging errors based on a predetermined criterion and provides advice for reducing the number of re-imaging operations, thereby reducing unnecessary imaging errors and re-inspections after the inspection is completed.

[0097] In addition, when the X-ray image 30 is a photographing error based on the analysis result of the image processing unit 62, the operator can be notified of the photographing error. The notification method can be any method that can notify the operator of the photographing error, and a display, sound, or other notification method can be used, but a method that does not cause anxiety to the subject Obj, that is, the patient is preferred. After shooting, the operator usually confirms the X-ray image 30 displayed on the display 17, so it is preferred to use a notification method that displays on the display 17. For example, when the X-ray image 30 is set as a photographing error, the display control unit 64 notifies that the image is an X-ray image 30b that is a photographing error by displaying a notification icon on the display 17.

[0098] The display method displayed on the display 17 may be any method as long as the operator can understand that the X-ray image 30b is set as a shooting error. For example, the color of the screen of the display 17 is changed, a notification icon for an alarm is displayed, or the notification icon is always displayed on the display 17 and the display of the notification icon is changed. When the captured X-ray image 30 is confirmed after shooting, the operator is notified of the fact that the captured X-ray image 30 is set as a shooting error based on the analysis result of the image processing unit 62 by checking the display 17.

[0099] Furthermore, since it takes time for the operator to perform analysis, it is sometimes unclear whether, when it is not determined as a shooting error, it is not determined as a shooting error because the analysis is in progress, or whether it is determined as a shooting success.

[0100] Therefore, during analysis, information on the time required for analysis may be displayed on the display 17. For example, a time bar or the like may be displayed on the display 17 so that it can be determined whether analysis is in progress or has been completed.

[0101] like Fig.12 As shown, the display instruction receiving unit 63 includes a correction information display instruction receiving unit 76 and a shooting error reason display instruction receiving unit 77. The display instruction receiving unit 63 receives an instruction of whether to display the correction information or the shooting error reason on the display 17, i.e., a correction information display instruction or a shooting error reason display instruction, and instructs the display control unit 64 on displaying the correction information or the shooting error reason.

[0102] The correction information display instruction receiving unit 76 receives a correction information display instruction for displaying correction information on the display 17. For example, an inspection engineer issues a correction information display instruction through the input device 18. When the X-ray image 30 is determined to be an imaging error, the correction information can be displayed according to the correction information display instruction.

[0103] Therefore, for example, in particular, by combining with the notification that the X-ray image 30 captured is a capture error, after the notification, the operator is instructed to display the correction information based on the judgment of the capture error of the X-ray image 30. Thus, compared with the case where the correction information is displayed without an instruction, the operator is required to confirm the X-ray image 30 and then judge whether to display the correction information, thereby preventing the judgment of the capture error of the X-ray image 30 from being delegated to the judgment of the capture error performed by the image processing unit 62 alone, or reducing the opportunity for correction related to the capture error judgment when the image processing unit 62 makes an inappropriate judgment of the capture error.

[0104] Similarly, the imaging error reason display instruction receiving unit 77 receives an imaging error reason display instruction of whether to display the imaging error reason on the display 17. For example, an operator such as an inspection engineer makes an imaging error reason display instruction through the input device 18. When the X-ray image 30 is determined to be an imaging error, it is possible to determine whether to display the imaging error reason according to the imaging error reason display instruction. Therefore, as in the case of the correction information display instruction, it is prevented from entrusting the imaging error determination of the X-ray image 30 only to the imaging error determination performed by the image processing unit 62, or when the imaging error determination of the image processing unit 62 is inappropriate, the opportunity for correction related to the imaging error determination is reduced.

[0105] More specifically, correction information display instructions or shooting error reason display instructions are given through the input device 18, such as a keyboard, a mouse, or the touch panel display 17, by a simple method such as key input, clicking, or touching an icon.

[0106] The display control unit 64 is responsible for a display control function of controlling the display of correction information or the reason for shooting error on the display 17 according to the instructions of the correction information display instruction receiving unit 76 and the reason for shooting error display instruction receiving unit 77 of the display instruction receiving unit 63. The correction information display instruction or the reason for shooting error display instruction can be given every time shooting is performed, and the content of the instruction can be continued until the next setting by setting once.

[0107] The display instruction receiving unit 63 is constructed as described above, so it can be set as follows, for example: a notification icon is always displayed in the display 17, and after the operator takes the X-ray image 30, when he is not sure whether to judge it as a shooting error, he clicks the notification icon to display the correction information or the reason for the shooting error.

[0108] In this way, when an imaging error occurs, the imaging error reason and / or correction information are not automatically displayed, but the operator needs to perform a display instruction operation, so that, for example, when the operator thinks that the imaging is successful, unnecessary display is not performed on the display 17, so that the work of confirming the X-ray image 30 is not hindered. In addition, even in a case other than the suggestion to re-shoot when the operator determines that the imaging error occurs, for example, when the operator is uncertain whether the imaging error is determined, by displaying the correction information and / or the imaging error reason obtained by the analysis of the X-ray imaging device 12, the judgment standard of the operator can be corrected to a predetermined standard, and the operator can confidently judge the imaging error of the X-ray image 30. In addition, the operator can confirm the imaging error judgment made by the X-ray imaging device 12, so when there is a problem in the imaging error judgment standard made by the X-ray imaging device 12, or when the imaging error judgment is wrong, it is prevented that the judgment based on the X-ray imaging device 12 is directly used as the judgment of the operator when the operator has not actually made the imaging error judgment on the X-ray image 30 himself.

[0109] like Fig.13 As shown, the X-ray imaging device 12 includes an approval receiving unit 81. When the X-ray image 30 is set as a photographing error, the approval receiving unit 81 receives whether the operator approves the photographing error. The operator approves through the input device 18. When the approval receiving unit 81 receives approval, the approval receiving unit 81 receives the X-ray image 30 and required information from the image processing unit 62, and sends these information to the communication unit 44, thereby sending these information to each unit. These information include a photographing command or an image file 31, etc.

[0110] As a form of approval, for example, an approval icon and a non-approval icon are displayed on the display 17, and when the operator approves the determination of the photographing error by the X-ray imaging device 12, the operator clicks the approval icon. In addition, below, the clicking also includes touching. On the other hand, when the operator does not approve the determination of the photographing error, the non-approval icon is clicked (refer to Fig.19 ).

[0111] When the approval icon is clicked, it means that the operator determines that the X-ray image 30 that was taken incorrectly by the X-ray imaging device 12 is an imaging error. Therefore, when the approval receiving unit 81 receives the approval of the operator, the same processing as when a normal imaging error occurs is performed.

[0112] like Fig.14As shown, for example, when the X-ray imaging system 10 including the X-ray imaging device 12 includes the RIS 79 for managing imaging orders, the approval receiving unit 81 receives approval of imaging error, and thus an order for re-imaging is registered in the RIS 79. The content of the re-imaging order is acquired based on the information of the imaging order of the approved X-ray image 30 or the information of the image file 31 including the X-ray image 30.

[0113] Furthermore, when the X-ray imaging system 10 including the X-ray imaging device 12 is connected to the PACS 78 storing the radiographic images and the information related to the radiographic images, the approval receiving unit 81 receives the approval of the operator, and thus obtains the information from the RIS 79 according to the situation, and sends the X-ray image 30 and the information related to the X-ray image 30 to the PACS 78. More specifically, the image file 31 including the X-ray image 30 is automatically registered in the PACS 78. The image file 31 is registered in the PACS 78 in accordance with the DICOM standard, and the information related to the imaging error is inputted by the X-ray imaging system 10.

[0114] Furthermore, in a case where the X-ray imaging system 10 including the X-ray imaging device 12 is provided with a shooting error management device (not shown) for managing the X-ray image 30b determined as a shooting error, when the approval receiving unit 81 receives approval of the shooting error of the X-ray image 30, the X-ray image 30b and information including the reason for the shooting error of the X-ray image 30b are sent to the shooting error management device.

[0115] In addition, it is also possible to adopt the following method: when the judgment of the shooting error is approved, the shooting error reason and / or correction information are displayed on the display 17, and when the operator approves all matters, the approval icon is clicked. For example, when the operator approves the situation of setting the X-ray image 30 as a shooting error, but does not approve the shooting error reason and / or correction information, the non-approval icon is clicked. Thus, it is also possible to adopt the following method: the operator can correct the part to be corrected in the shooting error reason and / or correction information. When the correction is completed, by clicking the approval icon, the information approved by the operator can be sent to each part of the RIS and / or PACS.

[0116] Furthermore, if the operator does not approve the fact that the X-ray imaging device 12 sets the X-ray image 30b as a photographing error, the operator clicks the non-approval icon. Thus, the operator changes the fact that the X-ray imaging device 12 sets the X-ray image 30b as a photographing error. Furthermore, in this case, the operator writes down the reason for changing the determination made by the X-ray imaging device 12. In addition, the operator can use this reason to correct the determination criterion of photographing error of the image processing unit 62.

[0117] When the operator sets the X-ray image 30 that has been set as a shooting error by the image processing unit 62 as unapproved by clicking the unapproved icon, as described above, a screen is displayed on which the operator can select whether to cancel the shooting error, change the reason for the shooting error, or change the correction information for editing. When the shooting error is canceled, the X-ray image 30 and information related to the X-ray image 30 are sent to the PACS as a successfully shot image. More specifically, the image file 31 including the X-ray image 30 is automatically registered in the PACS.

[0118] In this way, based on the approval of the operator, the operation and procedures when the operator determines that the image is an image error can be automatically performed by a simple operation such as clicking the approval icon. Therefore, the efficiency of the work can be achieved. When the final judgment of judging the X-ray image 30 as an image error or judging that it is not an image error is made, it becomes a signal that the image is finished for one image order.

[0119] Next, refer to Fig.15 The flowchart of will explain the action based on the above structure. First, the operator confirms the content of the imaging command 21 on the display 17, and sets the desired imaging menu corresponding to the imaging command 21 via the input device 18. Thus, the set imaging menu and the condition setting signal including the corresponding irradiation conditions are sent from the console 16 to the X-ray detection panel 15. After setting the imaging menu, the operator sets the same irradiation conditions as those corresponding to the set imaging menu to the radiation source control device 14 via the touch panel. Then, the operator starts the relative positioning of the X-ray source 13, the X-ray detection panel 15 and the object Obj.

[0120] For example, when the shooting menu is "Knee / Bent Posture / Side View" and you want to shoot a side view of the knee joint, Fig.16 As shown, the operator places the object Obj, i.e., the knee part, on the bed 83 in a manner perpendicular to the X-ray source 13. The X-ray detection panel 15 is set at a position directly opposite to the X-ray source. And at this time, the operator sets the size of the irradiation opening of the irradiation field limiter, i.e., the irradiation field, to the ray source control device 14 via the touch panel. The operator operates the irradiation field display light source to illuminate the irradiation field display light to the electronic dark box. The operator uses the irradiation field display light as a clue to make fine adjustments to the positions of the X-ray source 13, the X-ray detection panel 15, and the object Obj in such a way that the positional relationship becomes the desired relationship.

[0121] After positioning, the operator operates the irradiation switch to generate X-rays Ra from the X-ray source 13. The X-rays Ra irradiated from the X-ray source 13 and transmitted through the subject are irradiated onto the front surface of the X-ray detection panel 15. In the X-ray detection panel 15, the start of irradiation of the X-rays Ra is detected by the irradiation start detection function. Thus, an irradiation start detection signal is wirelessly transmitted from the X-ray detection panel 15 to the console 16. After the start of irradiation of the X-rays Ra is detected, in the X-ray detection panel 15, a pixel charge accumulation action and an image reading action are performed to detect the X-ray image 30. The X-ray image 30 is wirelessly transmitted from the X-ray detection panel 15 to the console 16.

[0122] When the captured X-ray image 30 is wirelessly transmitted to the console 16, Fig.17 As shown, the X-ray image 30 and a notification icon 91 are displayed on the management screen 90 of the X-ray imaging system of the display 17. The notification icon 91 can be in a cartoon shape, for example. In addition, the notification icon 91 is always displayed.

[0123] In the console 16, by receiving the X-ray image 30, such as Figure 7 As shown in FIG. 1 , in the CPU 43, the image acquisition unit 61, the image processing unit 62, the display instruction receiving unit 63 and the display control unit 64 start to operate. The image acquisition unit 61 receives the X-ray image 30 and sends it to the image processing unit 62. The image processing unit 62 analyzes the X-ray image 30. Figure 8 As shown, the imaging error determination unit 71 determines whether there is an imaging error on the X-ray image 30. The determination is performed using the learned model 72a.

[0124] When the analysis is completed and the analysis result shows that the X-ray image 30 is an imaging error, the imaging error reason determination unit 73a determines the imaging error reason based on the information from the imaging error determination unit 71 and, in some cases, based on information such as the imaging order 21 and / or the image file 31. The imaging error reason determination unit 73a uses the determined reason and the imaging error reason / correction information table 52a stored in the imaging error reason DB 52, and, depending on the situation, also uses information such as the imaging order 21 and / or the image file 31 to determine the correction information corresponding to the imaging error reason.

[0125] In the notification screen 93 of the display 17, in order to notify the operator that the X-ray image 30 captured is a capture error, the expression of the notification icon 91 is changed and displayed. Fig.18 As shown, after X-ray photography, when the analysis result is not set as a shooting error, the notification icon 91 is displayed as a notification icon 91a with a closed mouth expression and no notification. Conversely, when the analysis result is set as a shooting error, the notification icon 91 is displayed as a notification icon 91b with an open mouth expression and with notification.

[0126] The operator checks the display 17 to confirm the captured X-ray image 30, and therefore also checks the notification icon 91 ( Fig.15 , step ST100). In this case, the notification icon 91 is a notification icon 91b. When the operator wishes to confirm the correction information or the reason for the shooting error ("Yes" in step ST110), the operator clicks the notification icon 91 with the cursor 92 using a mouse or the like according to the situation (refer to Fig.17 , step ST120). Through this operation, Fig.19 As shown in FIG. 1 , the management screen 90 of the X-ray imaging system changes from the notification screen 93 to the correction information display screen 94. The correction information display screen 94 is a screen including a shooting error reason and / or correction information display section 96. The shooting error reason and / or correction information display section 96 includes a shooting error reason display section 96a and / or correction information display section 96b, an approval button 98, and a non-approval button 99. In addition, when the deviation amount information 87 is set to be displayed, as shown in FIG. Fig. 20 As shown, the deviation amount information 87 is displayed.

[0127] After confirming the reasons for the photographing error and / or the display contents in the correction information display unit 96, the operator clicks the disapproval button of the notification icon 91 (step ST140) when judging that the X-ray image 30 displayed on the display 17 is not a photographing error ("No" in step ST130). In this way, the data of the image file 31 input as a photographing error can be edited and changed. If necessary, the input is edited to be not a photographing error (step ST160), and the judgment that it is not a photographing error is input ("Yes" in step ST190).

[0128] On the other hand, when the X-ray image 30 displayed on the display 17 is judged to be a shooting error, and there is no objection to the contents shown in the shooting error reason and / or correction information display unit 96 ("Yes" in step ST130), the approval button 98 of the notification icon 91 is clicked (step ST150). If the approval button 98 is clicked, the shooting error processing of the X-ray image 30 is automatically performed (step ST180). In the display 17, the shooting error reason and / or correction information display unit 96 disappears, the notification icon 91 becomes a notification icon 91a without notification, and the state is restored to the standby state before shooting.

[0129] Furthermore, when the X-ray image 30 displayed on the display 17 is judged as a shooting error, and there is an objection to the shooting error reason and / or the content shown in the correction information display unit 96 ("No" in step ST130), if the non-approval button is clicked, a button for editing the shooting error judgment, correction information, and shooting error reason is displayed. When editing is not performed, it is set to be edited. When editing is performed, each edit button is clicked, and the shooting error judgment, correction information, and shooting error reason are edited (step ST160). By approving the shooting error judgment of the X-ray image 30 ("No" in step ST190), it is sent to the shooting error processing (step ST180), and the operator's shooting error judgment is completed.

[0130] In addition, even if the notification icon 91b with notification is displayed and the image processing unit 62 determines that the X-ray image 30 displayed on the display 17 is a shooting error, the operator can click the shooting error button 97 (step ST170) to handle the shooting error without clicking the notification icon 91 to display the correction information ("No" in step ST110) according to the judgment of the operator. Thus, the shooting error processing is automatically performed (step ST180). When the operator processes the shooting error of the X-ray image 30, the notification icon 91 becomes the notification icon 91a without notification, and returns to the standby state before shooting.

[0131] The automatic shooting error processing after clicking the approval button 98 or clicking the shooting error button 97 includes, for example, sending data to the shooting error management device, registering the shooting command for reshooting, and inputting the corresponding part of the DICOM format file. In this case, the approval receiving unit 81 obtains the required information from the image processing unit 62 and sends it to the communication unit 44. The communication unit 44 transmits various information to each unit. Thus, the transmission to the PACS, RIS and the shooting error management device is completed. In addition, the operation of each unit 80 to 84 of the CPU 43 stops.

[0132] In the above-mentioned embodiment, the hardware structure of the processing unit (processing unit) that performs various processes, such as the image acquisition unit 61, the image processing unit 62, the display control unit 64, the display instruction receiving unit 63, and the approval receiving unit 81, is various processors (processors) as shown below. The various processors include general-purpose processors that execute software (programs) and function as various processing units, namely CPUs (Central Processing Units), processors that can change the circuit structure after manufacturing, such as FPGAs (Field Programmable Gate Arrays), namely Programmable Logic Devices (PLDs), and processors that have circuit structures specially designed to perform various processes, namely dedicated electrical circuits, etc. (Graphical Processing Units: GPUs / Graphic Processing Units).

[0133] A processing unit may be composed of one of these various processors, or may be composed of a combination of two or more processors of the same type or different types (for example, a combination of multiple FPGAs or a CPU and FPGA, a combination of a GPU and a CPU). Furthermore, multiple processing units may be composed of one processor. As an example of a plurality of processing units composed of one processor, first, there is a method in which a processor is composed of a combination of one or more CPUs and software, such as represented by a computer such as a client or server, and the processor functions as multiple processing units. Second, there is a method in which a processor is used that implements the functions of the entire system including multiple processing units, such as represented by a system on chip (SystemOn Chip: SoC) or the like, using a single IC (Integrated Circuit) chip. In this way, various processing units are composed of one or more of the above-mentioned various processors as a hardware structure.

[0134] Furthermore, more specifically, the hardware structure of these various processors is an electric circuit (circuitry) in which circuit elements such as semiconductor elements are combined.
