DETAILED DESCRIPTION

[0103] Hereinafter, an embodiment of the present application will be described with reference to the drawings. However, the scope of the application is not limited to the illustrated example.

[0104] <First Embodiment>

[0105] [Structure of dynamic image analysis system 100]

[0106] First, the structure of the first embodiment will be described.

[0107] Figure 1 shows the overall structure of the dynamic image analysis system 100 in the first embodiment.

[0108] As shown in Figure 1 , the dynamic image analysis system 100 is configured by connecting the photographing apparatus 1 and the photographing console 2 by a communication cable or the like, and connecting the photographing console 2 and the diagnostic console 3 via a communication network NT such as a LAN (Local Area Network). Each apparatus constituting the dynamic image analysis system 100 is based on the DICOM (Digital Image and Communications in Medicine) standard, and communication between the apparatuses is performed in accordance with DICOM.

[0109] [Structure of photographing apparatus 1]

[0110] ​The imaging apparatus 1 is, for example, a dynamic imaging apparatus that images a dynamic state of a lung that expands and contracts in accordance with a breathing motion, a heart that beats, or the like, which has periodicity (cyclicity). Dynamic imaging is imaging in which a plurality of images representing a dynamic state of an object are acquired by repeatedly irradiating the object with radiation such as X-rays in a pulsed manner at predetermined time intervals (pulse irradiation) or continuously at a low dose rate without interruption (continuous irradiation). Dynamic imaging is imaging of a moving state or a changing state, and is imaging for recording a moving picture. Dynamic imaging includes moving picture imaging. However, dynamic imaging does not include imaging of still images while a moving picture is displayed. A series of images obtained by dynamic imaging is referred to as a dynamic image. Each of the plurality of images that constitute a dynamic image is referred to as a frame image. In the following embodiments, a case in which dynamic imaging of a chest is performed by pulse irradiation will be described as an example.

[0111] The radiation source 11 is disposed at a position opposed to the radiation detection unit 13 with the object M interposed therebetween, and irradiates the object M with radiation (X-rays) in accordance with control by the radiation irradiation control unit 12.

[0112] The radiation irradiation control unit 12 is connected to the imaging console 2, and controls the radiation source 11 on the basis of radiation irradiation conditions input from the imaging console 2 to perform radiation imaging. The radiation irradiation conditions input from the imaging console 2 are, for example, a pulse repetition frequency, a pulse width, a pulse interval, a number of imaging frames per 1 imaging, a value of an X-ray tube current, a value of an X-ray tube voltage, a kind of an additional filter, or the like. The pulse repetition frequency is the number of times of radiation irradiation per 1 second, and coincides with a frame rate described later. The pulse width is the radiation irradiation time per 1 radiation irradiation. The pulse interval is the time from the start of 1 radiation irradiation to the start of the next radiation irradiation, and coincides with an interframe interval described later.

[0113] The radiation detection unit 13 is constituted by a semiconductor image sensor such as an FPD. The FPD has, for example, a glass substrate or the like, and a plurality of detection elements (pixels) are arranged in a matrix at predetermined positions on the substrate. The plurality of detection elements (pixels) detect radiation irradiated from the radiation source 11 and transmitted through the object M at least in accordance with the intensity of the radiation, and convert the detected radiation into an electric signal to accumulate the electric signal. Each pixel is constituted by, for example, a switching unit such as a TFT (Thin Film Transistor). In the FPD, there are an indirect conversion type in which X-rays are converted into an electric signal via a scintillator by a photoelectric conversion element, and a direct conversion type in which X-rays are directly converted into an electric signal, and any one of them can be used.

[0114] The radiation detection unit 13 is disposed so as to be opposed to the radiation source 11 with the object M interposed therebetween.

[0115] The readout control device 14 is connected to the imaging control console 2. Based on the image readout conditions input from the imaging control console 2, the readout control device 14 controls the switching units of each pixel in the radiation detection unit 13, switching them on and off to read the electrical signals accumulated in each pixel, thereby acquiring image data. This image data is a frame image. Furthermore, the readout control device 14 outputs the acquired frame images to the imaging control console 2. Image readout conditions include, for example, frame rate, frame interval, pixel size, and image size (matrix size). The frame rate is the number of frames acquired per second, consistent with the pulse repetition frequency. The frame interval is the time from the start of one frame image acquisition operation to the start of the next frame image acquisition operation, consistent with the pulse interval.

[0116] Here, the radiation irradiation control device 12 and the image reading control device 14 are interconnected and exchange synchronization signals to synchronize the radiation irradiation action and the image reading action.

[0117] [Structure of the camera control console 2]

[0118] The imaging control console 2 outputs radiation irradiation conditions and image reading conditions to the imaging device 1, controls the radiation imaging and radiation image reading actions based on the imaging device 1, and displays the dynamic images acquired by the imaging device 1 as confirmation and diagnosis images to confirm whether they are suitable for positioning by the imaging technician or other imaging implementer.

[0119] like Figure 1 As shown, the shooting control console 2 is composed of a control unit 21, a storage unit 22, an operation unit 23, a display unit 24, and a communication unit 25, and each unit is connected by a bus 26.

[0120] The control unit 21 consists of a CPU (Central Processing Unit) and RAM (Random Access Memory). Based on the operation of the operation unit 23, the CPU of the control unit 21 reads the system program and various processing programs stored in the storage unit 22 and expands them in the RAM. It then executes various processes, including the shooting control processing (described later), according to the expanded programs, and centrally controls the actions of each part of the shooting control console 2, the radiation irradiation operation of the shooting device 1, and the reading operation.

[0121] The storage unit 22 is composed of a non-volatile semiconductor memory, a hard disk, or the like. The storage unit 22 stores various programs executed in the control unit 21, parameters required for program execution, and processing results, etc. For example, the storage unit 22 stores data used for execution... Figure 2The program of the photographing control processing shown. In addition, the storage section 22 stores the radiation irradiation conditions and the image reading conditions in correspondence with the body parts (for example, the chest and the like). The various programs are stored in the form of readable program codes, and the control section 21 sequentially executes the actions corresponding to the program codes.

[0122] The operation section 23 is configured with a keyboard having a cursor key, a number input key, and various function keys, a mouse, or the like, and outputs the instruction signals input by the key operation of the keyboard or the mouse operation to the control section 21. In addition, the operation section 23 can have a touch panel on the display screen of the display section 24, in which case the instruction signals input via the touch panel are output to the control section 21.

[0123] The display section 24 is configured with a monitor such as an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube), or the like, and displays the input instructions, data, and the like from the operation section 23 in accordance with the instructions of the display signals input from the control section 21.

[0124] The communication section 25 is configured with a LAN adapter, a modem, a TA (Terminal Adapter), or the like, and controls the data transmission and reception between the respective devices connected to the communication network NT.

[0125] [Structure of the diagnosis console 3]

[0126] The diagnosis console 3 is a dynamic image analysis device for assisting the diagnosis of a doctor by acquiring a dynamic image from the photographing console 2, displaying the acquired dynamic image and the analysis result (analysis image) of the dynamic image.

[0127] As shown in Figure 1 The diagnosis console 3 is configured with a control section 31, a storage section 32, an operation section 33, a display section 34, and a communication section 35, and the respective sections are connected by a bus 36.

[0128] The control section 31 is configured with a CPU, a RAM, and the like. The CPU of the control section 31 reads out the system program and the various processing programs stored in the storage section 32 and expands them in the RAM in accordance with the operation of the operation section 33, and executes the various processes including the analysis possibility judgment process described later in accordance with the expanded programs, and centrally controls the actions of the respective sections of the diagnosis console 3. The control section 31 functions as an acquisition section, a judgment section, a display control section, a notification section, and an output section.

[0129] The storage section 32 is configured from a nonvolatile semiconductor memory, a hard disk, or the like. The storage section 32 stores various programs including a program for executing the analysis possibility judgment processing in the control section 31, parameters required for program execution processing, or data of processing results and the like. These various programs are stored in the form of readable program codes, and the control section 31 sequentially executes actions corresponding to the program codes.

[0130] In addition, in the storage section 32, past photographed dynamic images are stored in correspondence with examination orders (order information) including patient information (for example, patient ID, patient's name, height, weight, age, sex, and the like), examination information (for example, examination ID, examination date, body part to be photographed, kind of dynamic of diagnosis object (for example, quiet breathing, deep breathing, breath-holding, and the like)), and the like. In addition, electronic medical record information corresponding to the dynamic images can be acquired from an unillustrated electronic medical record device and stored in correspondence with the dynamic images.

[0131] The operation section 33 is configured with a keyboard having cursor keys, number input keys, various function keys, and the like, a mouse, or the like, and outputs instruction signals input by key operation of the keyboard or by mouse operation to the control section 31. In addition, the operation section 33 can be provided with a touch panel on the display screen of the display section 34, in which case, instruction signals input via the touch panel are output to the control section 31.

[0132] The display section 34 is configured from a monitor such as an LCD, a CRT, or the like, and performs various displays according to instructions of display signals input from the control section 31.

[0133] The communication section 35 is provided with a LAN adapter, a modem, a TA, or the like, and controls data transmission and reception between each device connected to the communication network NT.

[0134] [Action of the dynamic image analysis system 100]

[0135] Next, the action of the above-described dynamic image analysis system 100 in the present embodiment will be described.

[0136] (Action of the photographing device 1, the photographing console 2)

[0137] First, the photographing action based on the photographing device 1, the photographing console 2 will be described.

[0138] Figure 2 The photographing control processing executed in the control section 21 of the photographing console 2 is shown. The photographing control processing is executed by cooperation of the control section 21 and the program stored in the storage section 22.

[0139] First, the operator photographs the operation section 23 of the photographing console 2, and inputs the patient information and the examination information of the subject (step S1).

[0140] Next, the radiation irradiation conditions are read from the storage section 22 and set to the radiation irradiation control device 12, and the image reading conditions are read from the storage section 22 and set to the reading control device 14 (step S2).

[0141] Next, the indication of the radiation irradiation based on the operation of the operation section 23 is waited for (step S3). Here, the operator positions the subject M between the radiation source 11 and the radiation detection section 13. In addition, the subject is instructed to take a breath in a state corresponding to the kind of the dynamic to be diagnosed. At the time when the photographing is ready, the radiation irradiation indication is input by operating the operation section 23.

[0142] If the radiation irradiation indication is input by the operation section 23 (step S3: Yes), the photographing start indication is output to the radiation irradiation control device 12 and the reading control device 14, and the dynamic photographing is started (step S4). That is, the radiation is irradiated by the radiation source 11 with the pulse interval set in the radiation irradiation control device 12, and the frame images are acquired by the radiation detection section 13.

[0143] If the photographing of the predetermined number of frames is completed, the photographing end indication is output to the radiation irradiation control device 12 and the reading control device 14 by the control section 21, and the photographing operation is stopped. The number of frames photographed is at least the number of frames capable of photographing one breath cycle.

[0144] The frame images acquired by the photographing are sequentially input to the photographing console 2, stored in the storage section 22 in correspondence with the numbers (frame numbers) indicating the photographing order (step S5), and displayed on the display section 24 (step S6). The operator confirms the positioning and the like by the displayed dynamic images, and judges whether the images suitable for the diagnosis are acquired by the photographing (photographing OK) or the re-photographing is required (photographing NG). Then, the operation section 23 is operated, and the judgment result is input.

[0145] If the judgment result indicating OK for the photographing is input by the prescribed operation of the operation section 23 (Step S7: Yes), the order information including the identification ID for identifying the dynamic image, the patient information, the examination information, the radiation irradiation conditions, the image reading conditions, the number indicating the photographing order (frame number), and the like is attached to the series of frame images acquired by the dynamic photographing (for example, written to the header region of the image data in the DICOM form), and transmitted to the diagnostic console 3 via the communication section 25 (Step S8). Then, the present processing is ended. On the other hand, if the judgment result indicating NG for the photographing is input by the prescribed operation of the operation section 23 (Step S7: No), the series of frame images stored in the storage section 22 are deleted (Step S9), and the present processing is ended. In this case, the photographing needs to be performed again.

[0146] (Action of diagnostic console 3)

[0147] Next, the action in the diagnostic console 3 will be described.

[0148] In the diagnostic console 3, if the series of frame images of the dynamic image are received from the photographing console 2 via the communication section 35, the analysis possibility judgment processing shown in Fig. 6 is executed by the cooperation of the control section 31 and the program stored in the storage section 32. Figure 3

[0149] If the analysis possibility judgment processing is started, first, the control section 31 of the diagnostic console 3 acquires the order information attached to the dynamic image received via the communication section 35 (Step Sll).

[0150] Next, the control section 31 decides the kind of dynamic analysis based on the order information acquired in Step Sll (Step S12). Specifically, the control section 31 decides the kind of dynamic analysis based on the kind of dynamic of the diagnosis object (for example, quiet breathing, deep breathing, breath-hold, and the like) included in the order information. Here, the dynamic analysis refers to the analysis of the dynamic image for the purpose of providing data for reference for the doctor for the diagnosis. As the kind of dynamic analysis, for example, there are ventilation analysis, blood flow analysis, maximum lung field area, lung field area change rate, diaphragm movement amount, motion analysis of the lung field, and the like, and in addition to these analyses, there are adhesion analysis for analyzing whether the tissues which should be separated from each other are not closely adhered to each other, orthopedic analysis for measuring the angle and distance of the bone and bone in the joint, and the like.

[0151] ​More specifically, in the storage section 32, for each kind of dynamic of the diagnostic subject, kinds of dynamic analysis are correspondingly stored, for example, with respect to the kind of dynamic "breath-holding", two kinds of blood flow analysis and maximum lung field area are correspondingly stored as kinds of dynamic analysis. Also, for example, with respect to the kind of dynamic "deep breathing", four kinds of ventilation analysis, lung field area change rate, diaphragm movement amount, and motion analysis of the lung field are correspondingly stored as kinds of dynamic analysis.

[0152] Thus, in the case where the kind of dynamic of the diagnostic subject included in the order information acquired in step Sll is "breath-holding", two kinds of blood flow analysis and maximum lung field area are decided as kinds of dynamic analysis corresponding to the "breath-holding".

[0153] Also, in the case where the kind of dynamic of the diagnostic subject included in the order information acquired in step Sll is "deep breathing", four kinds of ventilation analysis, lung field area change rate, diaphragm movement amount, and motion analysis of the lung field are decided as kinds of dynamic analysis corresponding to the "deep breathing".

[0154] Next, the control section 31 decides the criteria of the characteristic quantity associated with the dynamic analysis decided in step S12 (step S13).

[0155] More specifically, in the storage section 32, for each kind of dynamic analysis, criteria of the corresponding characteristic quantity are stored, for example, for blood flow analysis, the following (1-1) to (1-5) are correspondingly stored as criteria of the characteristic quantity.

[0156] (1-1) S value (dose index) < 5000

[0157] (1-2) Diaphragm movement amount < 5 mm

[0158] (1-3) Body movement < 10 mm

[0159] (1-4) Accuracy of supine position > 90%

[0160] (1-5) Accuracy of no defect in the lung field > 90%

[0161] Also, for example, for maximum lung field area, the following (2-1) to (2-2) are correspondingly stored as criteria of the characteristic quantity.

[0162] (2-1) Accuracy of maximum inspiration > 90%

[0163] (2-2) Accuracy of no defect in the lung field > 90%

[0164] Further, for example, for ventilation analysis, the criteria corresponding to (3-1) to (3-6) described below are stored as criteria of features.

[0165] (3-1) S value < 5000

[0166] (3-2) Diaphragm movement amount ≥ 5 mm

[0167] (3-3) Body motion ≤ 10 mm

[0168] (3-4) Accuracy of lung field absence ≥ 90%

[0169] (3-5) Difference in respiratory cycle between past dynamic images ≤ 10%

[0170] (3-6) Accuracy of supine position ≥ 90%

[0171] Further, for example, for lung field area change rate, the criteria corresponding to (4-1) to (4-2) described below are stored as criteria of features.

[0172] (4-1) Accuracy of lung field absence ≥ 90%

[0173] (4-2) Accuracy of maximum inhalation inclusion ≥ 90%

[0174] Further, for example, for diaphragm movement amount, the criteria corresponding to (5-1) to (5-2) described below are stored as criteria of features.

[0175] (5-1) Body motion ≤ 5 mm

[0176] (5-2) Accuracy of diaphragm absence ≥ 90%

[0177] Further, for example, for lung field movement analysis, the criteria corresponding to (6-1) to (6-3) described below are stored as criteria of features.

[0178] (6-1) Accuracy of lung field absence ≥ 90%

[0179] (6-2) Accuracy of supine position ≥ 90%

[0180] (6-3) Diaphragm movement amount ≥ 5 mm

[0181] Thus, in the case where the kind of dynamic analysis decided in step S12 is either of blood flow analysis and maximum lung field area, the criteria of features associated with blood flow analysis and maximum lung field area, respectively, are decided on the basis of the criteria described above stored in the storage section 32.

[0182] In addition, in a case where the kind of dynamic analysis decided in step S12 is four kinds of ventilation analysis, lung field area change rate, diaphragm movement amount, and lung field movement analysis, the control section 31 decides the criteria of the characteristic amount respectively associated with the ventilation analysis, the lung field area change rate, the diaphragm movement amount, and the lung field movement analysis, based on the above-described criteria stored in the storage section 32.

[0183] Next, the control section 31 calculates the characteristic amount associated with the dynamic analysis decided in step S12 (step S14).

[0184] For example, in a case where the kind of dynamic analysis decided in step S12 is two kinds of blood flow analysis and maximum lung field area, the control section 31 calculates the S value, the diaphragm movement amount, the body motion, the accuracy of the recumbent position, the accuracy that the lung field is not lacking, and the accuracy as the maximum inspiration, as the characteristic amount, based on the dynamic image received from the photographing console 2, respectively.

[0185] In addition, for example, in a case where the kind of dynamic analysis decided in step S12 is four kinds of ventilation analysis, lung field area change rate, diaphragm movement amount, and lung field movement analysis, the control section 31 calculates the S value, the diaphragm movement amount, the body motion, the accuracy of the recumbent position, the accuracy that the lung field is not lacking, the difference in the respiratory cycle from the past dynamic image, the accuracy including the maximum inspiration, and the accuracy that the diaphragm is not lacking, as the characteristic amount, based on the dynamic image received from the photographing console 2, respectively.

[0186] Next, the control section 31 determines whether or not there is the characteristic amount that does not satisfy the criteria of the characteristic amount decided in step S13 (step S15).

[0187] In step S15, in a case where it is determined that there is the characteristic amount that does not satisfy the criteria of the characteristic amount decided in step S13 (step S15: Yes), the control section 31 displays a determination result screen in which the gist that the dynamic analysis for which the decision of the criteria of the characteristic amount is performed is not analyzable (unsuitable information) is displayed recognizably and the reason for which it is not analyzable (unsuitable information) is displayed, in the display section 34 (step S16).

[0188] For example, in a case where the kind of dynamic analysis decided in step S12 is two kinds of blood flow analysis and maximum lung field area, and based on the dynamic image received from the photographing console 2, the S value (for example, 3000), the diaphragm movement amount (for example, 8 mm), the body movement (for example, 5 mm), the accuracy of the supine position (for example, 90%), the accuracy of the lung field having no defect (for example, 99.9%), and the accuracy of the maximum inspiration (for example, 90%) are calculated as the characteristic quantities, the diaphragm movement amount (for example, 8 mm) described above is determined as the characteristic quantity that does not satisfy the criterion (diaphragm movement amount ≤ 5 mm). Therefore, the control section 31 displays the gist that the blood flow analysis for which the criterion "diaphragm movement amount ≤ 5 mm" is decided as the characteristic quantity is not analyzable in a recognizable manner, and the judgment result screen 41 that displays the reason for the unanalyzability is displayed on the display section 34. Further, in the case described above, the characteristic quantities associated with the maximum lung field area all satisfy the criterion, and therefore, for the maximum lung field area, the gist that is analyzable is displayed in the judgment result screen 41. In addition, the control section 31 can perform, for example, sound output of the gist that the blood flow analysis is not analyzable and sound output of the reason for the unanalyzability together with the display (output) of the judgment result screen 41 to the display section 34. Further, the control section 31 can perform, for example, decorative light display such as flickering display of the list display area 411 described later when the judgment result screen 41 is displayed on the display section 34.

[0189] Figure 4 An example of the judgment result screen 41 described above is shown. In the judgment result screen 41, a list display area 411 that displays a list of possible analysis processes is provided on the right side of the screen.

[0190] In the list display area 411, the gist that the blood flow analysis is not analyzable is displayed in a state where the check of the check box corresponding to the blood flow analysis is canceled in a recognizable manner. In addition, the reason for the unanalyzability of the blood flow analysis (for example, diaphragm movement amount: 8 mm (NG)) is displayed. On the other hand, the gist that the maximum lung field area is analyzable is displayed in a state where the check box corresponding to the maximum lung field area is checked in a recognizable manner.

[0191] In addition, in the judgment result screen 41, an analysis image display area 412 is provided on the left side of the list display area 411, and the analysis image of the dynamic analysis that is judged to be analyzable can be displayed in the analysis image display area 412.

[0192] In the example described above, it is determined that the maximum lung field area is analyzable, and therefore an analysis image related to the maximum lung field area can be displayed in the analysis image display area 412. On the other hand, in the example described above, it is determined that the blood flow analysis is not analyzable, and therefore a control process is performed so that an analysis image of the blood flow analysis is not displayed in the analysis image display area 412.

[0193] Returning to the description of the analysis possibility determination process, after the display of the determination result screen 41 described above on the display section 34, the control section 31 causes a necessity / unnecessity selection screen 42 for making the user select whether or not to perform rephotography of the dynamic image to be displayed on the display section 34 (step S17), and ends the analysis possibility determination process.

[0194] Figure 5 An example of the necessity / unnecessity selection screen 42 described above is shown in FIG. 8. In this selection screen 42, message information asking the user whether or not to perform rephotography of the dynamic image (for example, text information of "Perform rephotography of the dynamic image?") is displayed, and a YES button 421 and a NO button 422 are provided.

[0195] The YES button 421 is a button for making a YES answer to the message information described above. If an operation of selecting the YES button 421 is performed by the operation section 33, information of the gist of the necessity of rephotography of the dynamic image is transmitted from the control section 31 to the photographing console 2 via the communication section 35. In addition, if the operation of selecting this YES button 421 is performed, the display of the necessity / unnecessity selection screen 42 is set to non-display.

[0196] The NO button 422 is a button for making a NO answer to the message information described above. If an operation of selecting the NO button 422 is performed by the operation section 33, the display of the necessity / unnecessity selection screen 42 is set to non-display.

[0197] In addition, in step S15, in the case where it is determined that there is no feature quantity that does not satisfy the criterion of the feature quantity decided in step S13 (step S15: NO), the control section 31 displays the determination result screen showing the gist of the determination that the dynamic analysis is analyzable, which is decided in step S12, on the display section 34 (step S18), and ends the analysis possibility determination process.

[0198] For example, in a case where the kind of dynamic analysis decided in step S12 is two kinds of blood flow analysis and maximum lung field area, and the feature quantities are an S value (for example, 3000), diaphragm movement amount (for example, 5 mm), body movement (for example, 5 mm), accuracy of recumbent position (for example, 90%), accuracy of absence of defect in lung field (for example, 99.9%), and accuracy of maximum inspiration (for example, 90%) are calculated as feature quantities based on the dynamic image received from the photographing console 2, it is determined that there is no feature quantity that does not satisfy the criteria of the feature quantities decided in step S13. Therefore, the control section 31 displays the judgment result screen 43 in which the gist that the blood flow analysis and the maximum lung field area are analyzable is displayed on the display section 34.

[0199] Figure 6 An example of the judgment result screen 43 described above is shown in FIG. 19. In the judgment result screen 43, as with the judgment result screen 41 described above, an overview display area 431 in which an overview of the possible analysis processes is displayed is provided on the right side of the screen.

[0200] In the overview display area 431, the gist that the blood flow analysis and the maximum lung field area are analyzable, respectively, is displayed, that is, in a state in which the check boxes corresponding to the blood flow analysis and the maximum lung field area, respectively, are checked.

[0201] In addition, in the judgment result screen 43, as with the judgment result screen 41 described above, an analysis image display area 432 is provided on the left side of the overview display area 431, and the analysis image of the dynamic analysis that is judged to be analyzable can be displayed in the analysis image display area 432.

[0202] In the example described above, the blood flow analysis and the maximum lung field area are judged to be analyzable, respectively, and therefore in the analysis image display area 432, the analysis images related to the blood flow analysis and the maximum lung field area, respectively, can be displayed.

[0203] As described above, in the diagnostic console 3 of the first embodiment, the dynamic image obtained by the radiological dynamic photographing is acquired, and based on the dynamic image, it is judged whether or not the dynamic image is suitable for the dynamic analysis.

[0204] Therefore, according to the diagnostic console 3 of the first embodiment, based on the acquired dynamic image, it is judged whether or not the dynamic image is suitable for the dynamic analysis, and thus it is possible to objectively judge whether or not the analysis result of the dynamic image can be used for diagnosis.

[0205] In addition, in the diagnostic console 3 of the first embodiment, based on the feature quantities associated with the dynamic analysis obtained from the dynamic image, it is judged whether or not the dynamic image is suitable for the dynamic analysis.

[0206] Therefore, according to the diagnostic console 3 of the first embodiment, the possibility determination is performed based on the feature quantity associated with the dynamic analysis obtained from the dynamic image, and thus the possibility determination can be accurately performed.

[0207] In addition, in the diagnostic console 3 of the first embodiment, the kind of the dynamic analysis on which the possibility determination is performed is determined from among a plurality of kinds of dynamic analysis.

[0208] Therefore, according to the diagnostic console 3 of the first embodiment, the dynamic analysis on which the possibility determination is performed is selectively selected, and thus the possibility determination can be efficiently performed.

[0209] In addition, in the diagnostic console 3 of the first embodiment, the kind of the dynamic analysis on which the possibility determination is performed is determined based on the order information.

[0210] Therefore, according to the diagnostic console 3 of the first embodiment, the dynamic analysis on which the possibility determination is performed is appropriately selectively selected in accordance with the order information, and thus the possibility determination can be efficiently and appropriately performed.

[0211] In addition, in the diagnostic console 3 of the first embodiment, the result of the possibility determination is displayed on the display section 34.

[0212] Therefore, according to the diagnostic console 3 of the first embodiment, the result of the possibility determination is displayed on the display section 34, and thus the user can grasp the result of the possibility determination.

[0213] In addition, in the diagnostic console 3 of the first embodiment, the analysis image of the dynamic image that is determined to be unsuitable by the possibility determination is not displayed on the display section 34.

[0214] Therefore, according to the diagnostic console 3 of the first embodiment, it is possible to prevent the analysis image of the dynamic image that is determined to be unsuitable by the possibility determination from being used for diagnosis.

[0215] In addition, in the diagnostic console 3 of the first embodiment, the analysis image of the dynamic image that is determined to be suitable by the possibility determination is displayed on the display section 34.

[0216] Therefore, according to the diagnostic console 3 of the first embodiment, only the analysis image of the dynamic image that is determined to be suitable by the possibility determination is used for diagnosis, and thus diagnosis using the analysis image of the dynamic image can be appropriately performed.

[0217] In addition, in the diagnostic console 3 of the first embodiment, in a case where the possibility determination is not suitable, notification related to rephotography is performed.

[0218] Therefore, according to the diagnostic console 3 of the first embodiment, in a case where it is judged to be unsuitable, notification relating to rephotography is performed, so that rephotography of the dynamic image can be prompted, and thus a series of work relating to dynamic analysis can be smoothly performed.

[0219] In addition, in the diagnostic console 3 of the first embodiment, the dynamic image obtained by the dynamic imaging based on the radiograph is acquired, in a case where the dynamic image is unsuitable for dynamic analysis, a gist of non-analyzability by dynamic analysis and a reason of non-analyzability (unsuitability information) are output, and an analysis image obtained by performing dynamic analysis on the dynamic image judged to be unsuitable is not displayed on the display section 34.

[0220] Therefore, according to the diagnostic console 3 of the first embodiment, the gist of non-analyzability by dynamic analysis and the reason of non-analyzability (unsuitability information) are output, so that the user can grasp the gist of unsuitability of the dynamic image for dynamic analysis. In addition, the analysis image obtained by performing dynamic analysis on the dynamic image judged to be unsuitable is not displayed on the display section 34, so that a case where the analysis image is used for diagnosis can be prevented.

[0221] In addition, in the diagnostic console 3 of the first embodiment, in a case where the dynamic image is suitable for dynamic analysis, an analysis image obtained by performing dynamic analysis on the dynamic image judged to be suitable is displayed on the display section 34.

[0222] Therefore, according to the diagnostic console 3 of the first embodiment, only the analysis image obtained by performing dynamic analysis on the dynamic image judged to be suitable for dynamic analysis is used for diagnosis, so that diagnosis using the analysis image of the dynamic image can be appropriately performed.

[0223] <Second Embodiment>

[0224] Hereinafter, a second embodiment of the present application will be described.

[0225] In the second embodiment, unlike the above-described first embodiment, it is characterized in that, after dynamic analysis on the dynamic image is performed in the diagnostic console 3, based on a result of the dynamic analysis, whether or not the dynamic image is suitable for dynamic analysis is judged.

[0226] Further, regarding the structure in the second embodiment, the same as the content described in the first embodiment except that the program for performing the analysis result judgment processing is stored in the storage section 32 of the diagnostic console 3, and thus the description is omitted, and hereinafter, the operation of the second embodiment will be described.

[0227] Figure 7is a flowchart showing an analysis result judgment process performed by the diagnosis console 3 in the second embodiment. This analysis result judgment process is performed by the cooperation of the control section 31 and the program stored in the storage section 32, on the occasion that a series of frame images of a dynamic image is received from the photographing console 2 via the communication section 35. The control section 31 functions as an acquisition section, a judgment section, a display control section, a notification section, and an output section.

[0228] If the analysis result judgment process is started, first, the control section 31 of the diagnosis console 3 implements a dynamic analysis (for example, a lung field area change rate) on the occasion that an input operation of instructing the implementation of the dynamic analysis is performed via the operation section 33 (step S21).

[0229] Next, the control section 31 calculates a change rate (second feature quantity) of the lung field area based on the lung field area calculated in each frame of the dynamic image (step S22).

[0230] Next, the control section 31 determines whether or not there is a frame in which the change rate of the lung field area is equal to or greater than a threshold value (step S23).

[0231] In the case where it is determined that there is a frame in which the change rate of the lung field area is equal to or greater than the threshold value in step S23 (step S23: Yes), the control section 31 displays the judgment result screen 44 in which the gist of the analysis failure and the reason thereof are displayed, on the display section 34 (step S24).

[0232] Figure 8 An example of the judgment result screen 44 described above is shown. In the judgment result screen 44, an analysis image display area 441 is provided in the center of the screen, in which message information of the gist of the analysis failure (for example, text information of "※ Analysis of the lung field area change rate has failed.") is displayed, and the reason of the analysis failure (for example, text information of "Abnormality of the lung field area change rate in the 10th frame") is displayed. That is, in the case where the dynamic analysis has failed, a control process is performed so that an analysis image related to the dynamic analysis is not displayed in the analysis image display area 441. Further, the control section 31 can perform sound output of the message information of the gist of the analysis failure, and sound output of the reason of the analysis failure, for example, together with the display (output) of the judgment result screen 44 to the display section 34. Also, the control section 31 can perform decorative light display such as flickering display of the analysis image display area 441, for example, when the judgment result screen 44 is displayed on the display section 34.

[0233] Next, the control section 31 displays the necessity and non-necessity selection screen 42 (refer to FIG. 8) for making the user select the necessity and non-necessity of rephotographing of the dynamic image, after the judgment result screen 44 described above is displayed on the display section 34 (step S25). Figure 5) and ends the analysis result judgment processing.

[0234] In addition, in a case where it is determined that there is no frame in which the lung field area change rate is equal to or greater than the threshold value (step S23: No), that is, in a case where it is determined that the analysis of the lung field area change rate has been appropriately performed, the control section 31 displays the analysis image of the lung field area change rate (omitted from illustration) in the analysis image display region 441 of the judgment result screen 44 (refer to FIG. 8) and ends the analysis result judgment processing (step S26). Figure 8

[0235] As described above, in the diagnostic console 3 of the second embodiment, a dynamic image obtained from radiation-based dynamic imaging is acquired, and a judgment of whether or not the dynamic image is suitable for dynamic analysis is performed based on an analysis result obtained by analyzing the dynamic image.

[0236] Therefore, according to the diagnostic console 3 of the second embodiment, a judgment of whether or not the dynamic image is suitable for dynamic analysis is performed based on an analysis result obtained by analyzing the dynamic image, so that it is possible to objectively judge whether or not the analysis result can be used for diagnosis.

[0237] In addition, in the diagnostic console 3 of the second embodiment, the judgment of whether or not is performed based on a second feature quantity (for example, the lung field area change rate) related to dynamic analysis obtained from the analysis result.

[0238] Therefore, according to the diagnostic console 3 of the second embodiment, the judgment of whether or not is performed based on a second feature quantity (for example, the lung field area change rate) related to dynamic analysis obtained from the analysis result, so that it is possible to accurately perform the judgment of whether or not.

[0239] In addition, in the diagnostic console 3 of the second embodiment, a result of the judgment of whether or not is displayed in the display section 34.

[0240] Therefore, according to the diagnostic console 3 of the second embodiment, a result of the judgment of whether or not is displayed in the display section 34, so that the user can grasp the result of the judgment of whether or not.

[0241] In addition, in the diagnostic console 3 of the second embodiment, an analysis image of a dynamic image that is judged to be unsuitable by the judgment of whether or not is not displayed in the display section 34.

[0242] Therefore, according to the diagnostic console 3 of the second embodiment, it is possible to prevent an analysis image of a dynamic image that is judged to be unsuitable by the judgment of whether or not from being used for diagnosis.

[0243] ​In addition, in the diagnostic console 3 of the second embodiment, the analysis image of the dynamic image judged to be suitable by the possibility judgment is displayed on the display section 34.

[0244] Therefore, according to the diagnostic console 3 of the second embodiment, the analysis image of the dynamic image judged to be suitable by the possibility judgment is used for diagnosis only, and thus the diagnosis using the analysis image of the dynamic image can be properly performed.

[0245] In addition, in the diagnostic console 3 of the second embodiment, in the case where the possibility judgment is not suitable, notification relating to rephotography is performed.

[0246] Therefore, according to the diagnostic console 3 of the second embodiment, in the case where the possibility judgment is not suitable, notification relating to rephotography is performed, and thus the rephotography of the dynamic image can be prompted, and thus the series of work relating to the dynamic analysis can be smoothly performed.

[0247] The first embodiment and the second embodiment of the present application have been described above, but the description in each embodiment is one example of the preferred embodiment of the present application, and is not limited thereto.

[0248] For example, in the first embodiment, the diagnostic console 3 is configured to delete the dynamic image acquired from the photography console 2 (the dynamic image to be the object of the dynamic analysis) in the case where it is determined in step S15 of the analysis possibility judgment process (see Figure 3 ) that there is a feature quantity that does not satisfy the criterion of the feature quantity decided in step S13 (step S15: YES), but can delete the dynamic image acquired from the photography console 2 (the dynamic image to be the object of the dynamic analysis) in the case where all the dynamic analysis is not analyzable which is decided in step S12.

[0249] In addition, in the second embodiment, the case where the control section 31 of the diagnostic console 3 performs the analysis result judgment process (see Figure 7 ) is described as an example, but the control section 31 can perform the analysis possibility judgment process (see Figure 3 ) described in the first embodiment first, for example, and perform the analysis result judgment process described in the second embodiment with the dynamic analysis judged to be analyzable in this process as the object.

[0250] In addition, in the first embodiment, the diagnostic console 3 is configured to delete the dynamic image acquired from the photography console 2 (the dynamic image to be the object of the dynamic analysis) in the case where it is determined in step S15 of the analysis possibility judgment process (see Figure 3In step S12, the kind of dynamic analysis is determined on the basis of the order information, but the kind of dynamic analysis desired by the user can be manually selected by the user performing a prescribed operation via the operation section 33, for example, without being based on the order information.

[0251] In addition, in the first embodiment and the second embodiment, the diagnostic console 3 is described as an example of the dynamic image analysis apparatus according to the present application, but the dynamic image analysis apparatus can be a PC (Personal Computer) dedicated to dynamic analysis, an image detection terminal, or the like, for example.

[0252] In addition, in the second embodiment, in the analysis result judgment processing (see Figure 7 ), as the dynamic analysis that becomes the object of the processing, the lung field area change rate is cited as an example, and the possibility judgment is performed on the basis of the lung field area change rate (second feature quantity), but the possibility judgment can be performed by the control section 31 on the basis of the heart ROI (second feature quantity) related to the blood flow analysis, for example, in the case of performing the blood flow analysis.

[0253] In addition, in the above description, an example of using a hard disk, a nonvolatile memory of a semiconductor, or the like as the computer-readable medium of the program according to the present application is disclosed, but the example is not limiting. As other computer-readable media, a portable recording medium such as a CD-ROM can be applied. In addition, as a medium of data of the program according to the present application provided via a communication line, a carrier wave (carrier wave) can be applied.

[0254] In addition, the detailed structure and the detailed operation of each apparatus constituting the dynamic image analysis system can be appropriately changed without departing from the gist of the present application.
