Background Art

[0002] Conventionally, a dynamic image obtained by radiographically imaging a dynamic of a subject having periodicity has been used for diagnosis. In a dynamic image, the dynamic of a subject that could not be captured in a still image can be displayed and analyzed.

[0003] In such a dynamic image, the reliability of the dynamic image affects the reliability of the image of the analysis result of the dynamic image, but it is not clear how reliable the image of the analysis result is just by looking at it. Therefore, for the purpose of making the reliability of the image of the above analysis result easy to understand, a dynamic image analysis device that displays reliability information indicating the reliability of the dynamic image together with the image of the analysis result of the dynamic image has been proposed (for example, see Patent Document 1).

[Figure 8] In the second embodiment, this is an example of the judgment result screen displayed on the display unit of the diagnostic console in Figure 1. [Modes for carrying out the invention]

[0025] Embodiments of the present invention will be described below with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[0026] <First Embodiment> [Configuration of the motion image analysis system 100] First, the configuration of the first embodiment will be described. Figure 1 shows the overall configuration of the dynamic image analysis system 100 in the first embodiment. As shown in Figure 1, the dynamic image analysis system 100 is configured such that the imaging device 1 and the imaging console 2 are connected by a communication cable, and the imaging console 2 and the diagnostic console 3 are connected via a communication network NT such as a LAN (Local Area Network). Each device constituting the dynamic image analysis system 100 conforms to the DICOM (Digital Image and Communications in Medicine) standard, and communication between each device is performed in accordance with DICOM.

[0027] [Configuration of imaging device 1] The imaging device 1 is an imaging means for capturing periodic (cycle-like) movements, such as the morphological changes of lung expansion and contraction associated with respiratory movement, and the beating of the heart. Dynamic imaging refers to acquiring multiple images showing the movement of a subject by repeatedly irradiating it with pulsed radiation, such as X-rays, at predetermined time intervals (pulsed irradiation), or by continuously irradiating it at a low dose rate without interruption (continuous irradiation). Dynamic imaging captures moving or fluctuating states and is used to record video; therefore, video recording is included in dynamic imaging. However, dynamic imaging does not include capturing still images while displaying video. A series of images obtained by dynamic imaging is called a dynamic image. Each of the multiple images that make up a dynamic image is called a frame image. In the following embodiment, the case of performing dynamic imaging of the chest by pulsed irradiation will be used as an example.

[0028] The radiation source 11 is positioned opposite the radiation detection unit 13 with the subject M in between, and irradiates the subject M with radiation (X-rays) according to the control of the radiation irradiation control device 12. The radiation irradiation control device 12 is connected to the imaging console 2 and controls the radiation source 11 to perform radiography based on the radiation irradiation conditions input from the imaging console 2. The radiation irradiation conditions input from the imaging console 2 include, for example, the pulse rate, pulse width, pulse interval, number of imaging frames per scan, X-ray tube current value, X-ray tube voltage value, and additional filter type. The pulse rate is the number of radiation irradiations per second and is the same as the frame rate, which will be described later. The pulse width is the radiation irradiation time per radiation irradiation. The pulse interval is the time from the start of one radiation irradiation to the start of the next radiation irradiation and is the same as the frame interval, which will be described later.

[0029] The radiation detection unit 13 is composed of a semiconductor image sensor such as an FPD. The FPD has, for example, a glass substrate, and multiple detection elements (pixels) are arranged in a matrix at predetermined positions on the substrate. These elements detect radiation irradiated from the radiation source 11 that has passed through at least the subject M according to its intensity, and convert the detected radiation into an electrical signal for storage. Each pixel is configured with a switching unit such as a TFT (Thin Film Transistor). FPDs can be of the indirect conversion type, which converts X-rays into electrical signals via a scintillator using a photoelectric conversion element, or the direct conversion type, which directly converts X-rays into electrical signals. Either type may be used. The radiation detection unit 13 is positioned to face the radiation source 11 with the subject M in between.

[0030] The reading control device 14 is connected to the imaging console 2. Based on the image reading conditions input from the imaging console 2, the reading control device 14 controls the switching unit of each pixel of the radiation detection unit 13, switching the reading of the electrical signals accumulated in each pixel, and acquires image data by reading the electrical signals accumulated in the radiation detection unit 13. This image data is a frame image. The reading control device 14 then outputs the acquired frame image to the imaging console 2. The image reading conditions are, for example, the frame rate, frame interval, pixel size, image size (matrix size), etc. The frame rate is the number of frame images acquired per second and is the same as the pulse rate. The frame interval is the time from the start of the acquisition operation of one frame image to the start of the acquisition operation of the next frame image and is the same as the pulse interval.

[0031] Here, the radiation irradiation control device 12 and the reading control device 14 are connected to each other and exchange synchronization signals to synchronize the radiation irradiation operation and the image reading operation.

[0032] [Configuration of shooting console 2] The imaging console 2 outputs radiation irradiation conditions and image reading conditions to the imaging device 1 to control the radiography and radiographic image reading operations of the imaging device 1, and also displays the dynamic images acquired by the imaging device 1 for the imaging technician or other person performing the imaging to confirm positioning and whether the images are suitable for diagnosis. As shown in Figure 1, the shooting console 2 is configured to include 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.

[0033] The control unit 21 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), etc. The CPU of the control unit 21 reads system programs and various processing programs stored in the memory unit 22 in response to operations on the operation unit 23, expands them into RAM, and executes various processes, including the imaging control process described later, according to the expanded programs, thereby centrally controlling the operation of each part of the imaging console 2, as well as the radiation irradiation and reading operations of the imaging device 1.

[0034] The storage unit 22 is composed of non-volatile semiconductor memory, a hard disk, or the like. The storage unit 22 stores data such as various programs executed by the control unit 21, parameters necessary for processing by the programs, or processing results. For example, the storage unit 22 stores a program for executing the imaging control processing shown in Figure 2. The storage unit 22 also stores radiation irradiation conditions and image reading conditions associated with the subject area (e.g., the chest). The various programs are stored in the form of readable program code, and the control unit 21 sequentially executes operations according to the program code.

[0035] The operation unit 23 is configured with a keyboard equipped with cursor keys, number input keys, and various function keys, and a pointing device such as a mouse, and outputs instruction signals input by key operations on the keyboard or mouse to the control unit 21. The operation unit 23 may also be equipped with a touch panel on the display screen of the display unit 24, in which case it outputs instruction signals input via the touch panel to the control unit 21.

[0036] The display unit 24 is composed of monitors such as LCDs (Liquid Crystal Displays) and CRTs (Cathode Ray Tubes), and displays input instructions and data from the operation unit 23 according to the instructions of the display signals input from the control unit 21.

[0037] The communication unit 25 is equipped with a LAN adapter, modem, TA (Terminal Adapter), etc., and controls the transmission and reception of data between it and each device connected to the communication network NT.

[0038] [Configuration of diagnostic console 3] The diagnostic console 3 is a dynamic image analysis device that acquires dynamic images from the imaging console 2 and displays the acquired dynamic images and the results of the dynamic image analysis (analyzed images) to support the physician's diagnosis. As shown in Figure 1, the diagnostic console 3 is configured to include a control unit 31, a storage unit 32, an operation unit 33, a display unit 34, and a communication unit 35, with each unit connected by a bus 36.

[0039] The control unit 31 is composed of a CPU, RAM, etc. The CPU of the control unit 31 reads system programs and various processing programs stored in the memory unit 32 in response to operations on the operation unit 33, expands them into RAM, and executes various processes, including the analysis feasibility determination process described later, according to the expanded programs, and centrally controls the operation of each part of the diagnostic console 3. The control unit 31 functions as an acquisition unit, a judgment unit, a display control unit, a notification unit, and an output unit.

[0040] The storage unit 32 is composed of non-volatile semiconductor memory, a hard disk, or the like. The storage unit 32 stores various programs, including a program for the control unit 31 to perform analysis feasibility determination processing, as well as parameters necessary for executing processing by the programs, and data such as processing results. These various programs are stored in the form of readable program code, and the control unit 31 sequentially executes operations according to the program code.

[0041] Furthermore, the memory unit 32 stores previously captured motion images in association with examination orders (order information) that include patient information (e.g., patient ID, patient name, height, weight, age, gender, etc.) and examination information (e.g., examination ID, examination date, subject area, type of motion being diagnosed (e.g., resting respiration, deep respiration, breath-holding, etc.)). In addition, electronic medical record information corresponding to the motion images may be acquired from an electronic medical record device (not shown) and stored in association with the motion images.

[0042] The operation unit 33 is configured with a keyboard equipped with cursor keys, number input keys, and various function keys, and a pointing device such as a mouse, and outputs instruction signals input by the user through key operations on the keyboard or mouse to the control unit 31. The operation unit 33 may also be equipped with a touch panel on the display screen of the display unit 34, in which case it outputs instruction signals input via the touch panel to the control unit 31.

[0043] The display unit 34 is composed of monitors such as LCDs and CRTs, and displays various information according to the instructions of the display signals input from the control unit 31.

[0044] The communication unit 35 is equipped with a LAN adapter, modem, TA, etc., and controls the transmission and reception of data between it and each device connected to the communication network NT.

[0045] [Operation of the motion image analysis system 100] Next, the operation of the dynamic image analysis system 100 in this embodiment will be described.

[0046] (Operation of imaging device 1 and imaging console 2) First, we will explain the shooting operation using the shooting device 1 and the shooting console 2. Figure 2 shows the shooting control process executed in the control unit 21 of the shooting console 2. The shooting control process is executed through the cooperation of the control unit 21 and the program stored in the storage unit 22.

[0047] First, the operator performing the imaging operates the control panel 23 of the imaging console 2 to input the patient's information and examination information (step S1).

[0048] Next, the radiation irradiation conditions are read from the storage unit 22 and set in the radiation irradiation control device 12, and the image reading conditions are read from the storage unit 22 and set in the reading control device 14 (step S2).

[0049] Next, the control unit 23 is set up to receive an instruction for radiation irradiation (step S3). At this point, the imaging operator positions the subject M between the radiation source 11 and the radiation detection unit 13. The operator also instructs the subject on their respiratory state according to the type of dynamics being diagnosed. Once the imaging preparations are complete, the control unit 23 is operated to input the instruction for radiation irradiation.

[0050] When a radiation irradiation instruction is input via the operation unit 23 (step S3; YES), a start-up instruction is output to the radiation irradiation control device 12 and the reading control device 14, and dynamic imaging begins (step S4). That is, radiation is irradiated by the radiation source 11 at pulse intervals set in the radiation irradiation control device 12, and frame images are acquired by the radiation detection unit 13.

[0051] Once a predetermined number of frames have been captured, the control unit 21 outputs an instruction to the radiation irradiation control device 12 and the reading control device 14 to end the shooting, and the shooting operation stops. The number of frames captured is the number of frames that can capture at least one respiratory cycle.

[0052] The frame images acquired through shooting are sequentially input to the shooting console 2, stored in the storage unit 22 in association with a number indicating the shooting order (frame number) (step S5), and displayed on the display unit 24 (step S6). The person performing the shooting checks the positioning, etc., from the displayed dynamic images and determines whether an image suitable for diagnosis has been acquired through shooting (shooting OK) or whether reshooting is necessary (shooting NG). Then, they operate the operation unit 23 to input the result of the determination.

[0053] When a judgment result indicating OK for shooting is input through a predetermined operation of the operation unit 23 (step S7; YES), order information including an identification ID for identifying the dynamic image, patient information, examination information, radiation irradiation conditions, image reading conditions, and a number indicating the shooting order (frame number) is attached to the series of frame images acquired by dynamic imaging (for example, written in the header area of ​​the image data in DICOM format), and transmitted to the diagnostic console 3 via the communication unit 25 (step S8). Then, this process ends. On the other hand, when a judgment result indicating NG for shooting is input through a predetermined operation of the operation unit 23 (step S7; NO), the series of frame images stored in the storage unit 22 are deleted (step S9), and this process ends. In this case, reshooting is required.

[0054] (Operation of diagnostic console 3) Next, we will explain the operation of the diagnostic console 3. In the diagnostic console 3, when a series of motion image frames are received from the imaging console 2 via the communication unit 35, the control unit 31 and the program stored in the storage unit 32 work together to execute the analysis feasibility determination process shown in Figure 3.

[0055] When the analysis feasibility determination process is initiated, the control unit 31 of the diagnostic console 3 first acquires order information attached to the dynamic image received via the communication unit 35 (step S11).

[0056] Next, the control unit 31 determines the type of dynamic analysis based on the order information acquired in step S11 (step S12). Specifically, the control unit 31 determines the type of dynamic analysis based on the type of dynamics of the subject to diagnosis included in the order information (e.g., resting respiration, deep respiration, breath-holding, etc.). Here, dynamic analysis refers to the analysis of dynamic images for the purpose of providing data that physicians can use as reference for diagnosis. Examples of dynamic analysis include ventilation analysis, blood flow analysis, maximum lung field area, lung field area change rate, diaphragm displacement, lung field movement analysis, etc. In addition to these analyses, there are also adhesion analysis, which analyzes whether tissues that should be separate are stuck together, and orthopedic analysis, which measures the angle and distance between bones in a joint.

[0057] More specifically, the memory unit 32 stores the type of dynamic analysis associated with each type of dynamic being diagnosed. For example, for the dynamic type "breath-holding," two types of dynamic analysis are stored: blood flow analysis and maximum lung area. Also, for example, for the dynamic type "deep breathing," four types of dynamic analysis are stored: ventilation analysis, lung area change rate, diaphragm movement, and lung field movement analysis. As a result, if the type of dynamic condition to be diagnosed included in the order information obtained in step S11 is "breath hold," then two types of dynamic analysis will be determined to be associated with this "breath hold": blood flow analysis and maximum lung area. Furthermore, if the type of dynamic to be diagnosed included in the order information obtained in step S11 is "deep breathing," then four types of dynamic analysis will be determined to be associated with this "deep breathing": ventilation analysis, lung field area change rate, diaphragmatic movement, and lung field movement analysis.

[0058] Next, the control unit 31 determines the criteria for the feature quantities related to the dynamic analysis determined in step S12 (step S13).

[0059] Specifically, the memory unit 32 stores the criteria for the corresponding feature quantities for each type of dynamic analysis. For example, for blood flow analysis, the following criteria (1-1) to (1-5) are associated with and stored as the criteria for the feature quantities. (1-1) S value (dose index) < 5000 (1-2) Diaphragmatic displacement ≤ 5 mm (1-3) Body movement ≤ 10 mm (1-4) Accuracy of supine position ≥ 90% (1-5) Probability of no missing lung fields ≥ 90%

[0060] Furthermore, for example, the following criteria (2-1) to (2-2) are associated with and stored as criteria for the maximum lung field area. (2-1) Probability of maximum intake ≥ 90% (2-2) Probability of no missing lung fields ≥ 90%

[0061] Furthermore, for example, for ventilation analysis, the following criteria (3-1) to (3-6) are associated with and stored as criteria for feature quantities. (3-1) S value < 5000 (3-2) Diaphragmatic displacement ≥ 5 mm (3-3) Body movement ≤ 10 mm (3-4) Probability of no missing lung fields ≥ 90% (3-5) Difference in respiratory cycle from past dynamic images ≤ 10% (3-6) Accuracy of supine position ≥ 90%

[0062] Furthermore, for example, the following criteria (4-1) to (4-2) are associated with and stored as feature criteria for the rate of change in lung area. (4-1) Probability of no missing lung fields ≥ 90% (4-2) Accuracy including maximum intake ≥ 90%

[0063] Furthermore, for example, the following criteria (5-1) to (5-2) are associated with and stored as criteria for the diaphragmatic displacement. (5-1) Body movement ≤ 5 mm (5-2) Probability that the diaphragm is not missing ≥ 90%

[0064] Furthermore, for example, in the analysis of lung field movement, the following criteria (6-1) to (6-3) are associated with and stored as criteria for feature quantities. (6-1) Probability of no missing lung fields ≥ 90% (6-2) Accuracy of supine position ≥ 90% (6-3) Diaphragmatic displacement ≥ 5 mm

[0065] Therefore, if the type of dynamic analysis determined in step S12 is blood flow analysis and maximum lung area, the criteria for the feature quantities related to blood flow analysis and maximum lung area, respectively, will be determined based on the above-mentioned criteria stored in the memory unit 32. Furthermore, if the type of dynamic analysis determined in step S12 is one of four types—ventilation analysis, lung field area change rate, diaphragmatic displacement, and lung field movement analysis—then the criteria for the feature quantities related to each of these will be determined based on the above-mentioned criteria stored in the memory unit 32.

[0066] Next, the control unit 31 calculates the feature quantities related to the dynamic analysis determined in step S12 (step S14). For example, if the type of dynamic analysis determined in step S12 is blood flow analysis and maximum lung field area, the control unit 31 calculates the S value, diaphragm displacement, body movement, accuracy of supine position, accuracy of no missing lung fields, and accuracy of maximum inspiration as features based on the dynamic image received from the imaging console 2. Furthermore, for example, if the type of dynamic analysis determined in step S12 is one of four types—ventilation analysis, lung field area change rate, diaphragm displacement, and lung field movement analysis—the control unit 31 calculates the following as features based on the dynamic images received from the imaging console 2: S value, diaphragm displacement, body movement, accuracy of supine position, accuracy of no missing lung fields, difference in respiratory cycle from past dynamic images, accuracy of including maximum inspiration, and accuracy of no missing diaphragm.

[0067] Next, the control unit 31 determines whether or not there are any features that do not meet the criteria for features determined in step S13 (step S15).

[0068] In step S15, if it is determined that there are features that do not meet the criteria for features determined in step S13 (step S15; YES), the control unit 31 displays a judgment result screen on the display unit 34 that identifies that the dynamic analysis for which the criteria for the features were determined is unsuitable for analysis (unsuitable information) and also displays the reason why it is unsuitable for analysis (unsuitable information) (step S16).

[0069] For example, if the type of dynamic analysis determined in step S12 is blood flow analysis and maximum lung area, and the following features are calculated based on the dynamic image received from the imaging console 2: S value (e.g., 3000), diaphragm displacement (e.g., 8 mm), body movement (e.g., 5 mm), supine position accuracy (e.g., 90%), accuracy of no missing lung fields (e.g., 99.9%), and accuracy of maximum inspiration (e.g., 90%), then the diaphragm displacement (e.g., 8 mm) will be determined to be a feature that does not meet the criterion (diaphragm displacement ≤ 5 mm). Therefore, the control unit 31 displays a judgment result screen 41 on the display unit 34 that indicates that the blood flow analysis, for which the criterion for the feature has been determined to be "diaphragm displacement ≤ 5 mm", is unanalyzable, and also displays the reason why it is unanalyzable. In this case, since all the features related to maximum lung area meet the criteria, the judgment result screen 41 will indicate that the maximum lung area is analyzable. Furthermore, the control unit 31 may, in conjunction with displaying (outputting) the judgment result screen 41 to the display unit 34, output an audio message indicating, for example, that blood flow analysis is not possible, as well as the reason why analysis is not possible. In addition, when displaying the judgment result screen 41 to the display unit 34, the control unit 31 may perform decorative light-emitting displays, such as flashing the list display area 411, which will be described later.

[0070] Figure 4 shows an example of the judgment result screen 41 described above. In this judgment result screen 41, a list display area 411 is provided on the right side of the screen, which displays a list of possible analysis processes. In this list display area 411, it is clearly indicated that blood flow analysis is unavailable; that is, the checkbox corresponding to blood flow analysis is unchecked. The reason why blood flow analysis is unavailable (for example, diaphragmatic displacement: 8 mm (NG)) is also displayed. On the other hand, it is clearly indicated that maximum lung field area is available for analysis; that is, the checkbox corresponding to maximum lung field area is checked.

[0071] Furthermore, in the judgment result screen 41, an analysis image display area 412 is provided to the left of the list display area 411, and the analysis images of the dynamic analysis that were determined to be analyzable can be displayed in the analysis image display area 412. In the example described above, since the maximum lung area is determined to be analyzable, the analysis image related to this maximum lung area can be displayed in the analysis image display area 412. On the other hand, in the example described above, since the blood flow analysis is determined to be unanalyzable, control processing is performed so that the analysis image of this blood flow analysis is not displayed in the analysis image display area 412.

[0072] Returning to the explanation of the analysis feasibility determination process, the control unit 31 displays the above determination result screen 41 on the display unit 34, then displays a necessity selection screen 42 on the display unit 34 as a pop-up (step S17) to allow the user to select whether or not to recapture the dynamic image, and then terminates the analysis feasibility determination process.

[0073] Figure 5 shows an example of the necessity selection screen 42 described above. This selection screen 42 displays a message asking the user whether or not to reshoot the motion images (for example, the text "Do you want to reshoot the motion images?"), and is also provided with a YES button 421 and a NO button 422.

[0074] The YES button 421 is used to respond with YES to the above message information. When the YES button 421 is selected via the operation unit 33, information indicating that the motion image needs to be recaptured is transmitted from the control unit 31 to the shooting console 2 via the communication unit 35. Also, when the YES button 421 is selected, the display of the necessity selection screen 42 is hidden. The NO button 422 is used to respond with NO to the above message information. When the NO button 422 is selected via the operation unit 33, the necessity selection screen 42 is hidden.

[0075] Furthermore, in step S15, if it is determined that there are no features that do not meet the feature criteria determined in step S13 (step S15; NO), the control unit 31 displays a judgment result screen on the display unit 34 indicating that the dynamic analysis determined in step S12 is analyzable (step S18), and terminates the analysis feasibility determination process.

[0076] For example, if the types of dynamic analysis determined in step S12 are blood flow analysis and maximum lung field area, and based on the dynamic images received from the imaging console 2, the S value (e.g., 3000), diaphragm displacement (e.g., 5 mm), body movement (e.g., 5 mm), accuracy of supine position (e.g., 90%), accuracy of no missing lung fields (e.g., 99.9%), and accuracy of maximum inspiration (e.g., 90%) are calculated as features, then it will be determined in step S13 that there are no features that do not meet the criteria for features. Therefore, the control unit 31 displays a determination result screen 43 on the display unit 34 indicating that blood flow analysis and maximum lung field area can be analyzed.

[0077] Figure 6 shows an example of the judgment result screen 43 described above. Similar to the judgment result screen 41 described above, this judgment result screen 43 has a list display area 431 on the right side of the screen that displays a list of possible analysis processes. In this list display area 431, it is indicated that both blood flow analysis and maximum lung area analysis are available, meaning that the corresponding checkboxes for blood flow analysis and maximum lung area are checked.

[0078] Furthermore, in the judgment result screen 43, similar to the judgment result screen 41 described above, an analysis image display area 432 is provided to the left of the list display area 431, and the analysis images of the dynamic analysis that were determined to be analyzable can be displayed in the analysis image display area 432. In the example described above, since both blood flow analysis and maximum lung area are deemed analyzable, the analysis images related to blood flow analysis and maximum lung area can be displayed in the analysis image display area 432.

[0079] As described above, the diagnostic console 3 of the first embodiment acquires dynamic images obtained from dynamic imaging using radiation, and makes a determination based on the dynamic images whether or not they are suitable for dynamic analysis. Therefore, according to the diagnostic console 3 of the first embodiment, by making a judgment on whether the acquired motion image is suitable or unsuitable for motion analysis, it becomes possible to objectively determine whether the analysis results of the motion image can be used for diagnosis.

[0080] Furthermore, in the diagnostic console 3 of the first embodiment, a determination was made as to whether or not a motion image is suitable for motion analysis based on the feature quantities related to motion analysis obtained from the motion image. Therefore, according to the diagnostic console 3 of the first embodiment, the determination of whether or not to perform a procedure can be made accurately by making the determination based on the features related to the dynamic analysis obtained from the dynamic image.

[0081] Furthermore, in the diagnostic console 3 of the first embodiment, the type of dynamic analysis for which the feasibility judgment is made is determined from among several types of dynamic analysis. Therefore, with the diagnostic console 3 of the first embodiment, it is possible to select and discard dynamic analyses for determining whether something is acceptable or not, thus enabling efficient determination of whether something is acceptable or not.

[0082] Furthermore, in the diagnostic console 3 of the first embodiment, the type of dynamic analysis used to determine whether or not to perform the operation was determined based on the order information. Therefore, according to the diagnostic console 3 of the first embodiment, dynamic analysis for determining whether or not to perform an order can be appropriately selected based on the order information, thus enabling efficient and appropriate determination of whether or not to perform the order.

[0083] Furthermore, in the diagnostic console 3 of the first embodiment, the result of the pass / fail judgment was displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the first embodiment, the result of the pass / fail judgment is displayed on the display unit 34, allowing the user to understand the result of the pass / fail judgment.

[0084] Furthermore, in the diagnostic console 3 of the first embodiment, the analysis images of dynamic images that are deemed unsuitable based on the feasibility assessment are not displayed on the display unit 34. Therefore, the diagnostic console 3 of the first embodiment prevents the use of analysis images of dynamic images that have been deemed unsuitable by the approval / rejection judgment for diagnosis.

[0085] Furthermore, in the diagnostic console 3 of the first embodiment, the analysis images of the dynamic images that were deemed suitable based on the feasibility assessment were displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the first embodiment, only the analyzed images of the motion images that are deemed suitable by the feasibility assessment will be used for diagnosis, thus enabling appropriate diagnosis using the analyzed images of the motion images.

[0086] Furthermore, in the diagnostic console 3 of the first embodiment, if a judgment of unsuitability was made, notification regarding re-imaging would have been issued. Therefore, according to the diagnostic console 3 of the first embodiment, if an image is deemed unsuitable, it is possible to prompt the re-capture of the motion image by providing notification regarding re-capture, thereby facilitating a series of operations related to motion analysis.

[0087] Furthermore, in the diagnostic console 3 of the first embodiment, dynamic images obtained from motion imaging using radiation are acquired, and if the dynamic images are unsuitable for motion analysis, a message indicating that motion analysis is not possible and the reason why (unsuitability information) is output, and the analysis images obtained by motion analysis of dynamic images deemed unsuitable are not displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the first embodiment, by outputting a statement that dynamic analysis is not possible and the reason why (unsuitable information), the user can understand that the dynamic image is unsuitable for dynamic analysis. Furthermore, by not displaying the analysis image obtained by dynamic analysis of a dynamic image deemed unsuitable on the display unit 34, it is possible to prevent the analysis image from being used for diagnosis.

[0088] Furthermore, in the diagnostic console 3 of the first embodiment, if a motion image is deemed suitable for motion analysis, the analysis image obtained by performing motion analysis on the motion image deemed suitable is displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the first embodiment, only the analyzed images obtained by dynamic analysis of dynamic images that are deemed suitable for dynamic analysis will be used for diagnosis, thus enabling appropriate diagnosis using the analyzed images of dynamic images.

[0089] <Second Embodiment> A second embodiment of the present invention will be described below. In this second embodiment, unlike the first embodiment described above, the diagnostic console 3 performs dynamic analysis on the dynamic image, and then, based on the results of the dynamic analysis, determines whether or not the dynamic image is suitable for dynamic analysis.

[0090] The configuration in the second embodiment is the same as that described in the first embodiment, except that a program for executing analysis result judgment processing is stored in the storage unit 32 of the diagnostic console 3. Therefore, the explanation will be omitted, and the operation of the second embodiment will be described below.

[0091] Figure 7 is a flowchart showing the analysis result determination process performed by the diagnostic console 3 in the second embodiment. This analysis result determination process is performed in cooperation with the control unit 31 and the program stored in the storage unit 32, triggered by the reception of a series of motion image frames from the imaging console 2 via the communication unit 35. The control unit 31 functions as an acquisition unit, a determination unit, a display control unit, a notification unit, and an output unit.

[0092] When the analysis result judgment process is started, the control unit 31 of the diagnostic console 3 first performs the dynamic analysis (for example, lung field area change rate) when an input operation is made via the operation unit 33 to instruct the execution of the dynamic analysis (step S21).

[0093] Next, the control unit 31 calculates the rate of change of the lung field area (second feature quantity) based on the lung field area calculated in each frame of the dynamic image (step S22).

[0094] Next, the control unit 31 determines whether or not there is a frame in which the rate of change of lung field area is greater than or equal to a threshold (step S23).

[0095] In step S23, if it is determined that there is a frame in which the rate of change of lung field area is greater than or equal to a threshold (step S23; YES), the control unit 31 displays a judgment result screen 44 on the display unit 34 indicating that the analysis failed and the reason for the failure (step S24).

[0096] Figure 8 shows an example of the judgment result screen 44 described above. In the judgment result screen 44, an analysis image display area 441 is provided in the center of the screen. In this analysis image display area 441, message information indicating that the analysis failed (for example, the text information "※Analysis of lung field area change rate failed.") is displayed, as well as the reason for the analysis failure (for example, the text information "Abnormal lung field area change rate in the 10th frame"). In other words, if the dynamic analysis fails, control processing is performed so that the analysis image related to the dynamic analysis is not displayed in the analysis image display area 441. The control unit 31 may also output a message indicating that the analysis failed and the reason for the analysis failure in addition to displaying (outputting) the judgment result screen 44 to the display unit 34. Furthermore, when the control unit 31 displays the judgment result screen 44 to the display unit 34, it may also perform decorative light-emitting displays, such as blinking the analysis image display area 441.

[0097] Next, the control unit 31 displays the judgment result screen 44 on the display unit 34, then pops up a necessity selection screen 42 (see Figure 5) on the display unit 34 to allow the user to select whether or not to recapture the dynamic image (step S25), and then terminates the analysis result judgment process.

[0098] Furthermore, if it is determined in step S23 that there are no frames in which the rate of change of lung area is greater than or equal to a threshold (step S23; NO), that is, if it is determined that the analysis of the rate of change of lung area has been performed appropriately, the control unit 31 displays the analyzed image of the rate of change of lung area (not shown) in the analyzed image display area 441 of the determination result screen 44 (see Figure 8) (step S26), and terminates the analysis result determination process.

[0099] As described above, in the diagnostic console 3 of the second embodiment, dynamic images obtained from dynamic imaging using radiation were acquired, and a determination was made as to whether or not the dynamic images were suitable for dynamic analysis based on the analysis results obtained by analyzing the dynamic images. Therefore, according to the diagnostic console 3 of the second embodiment, by determining whether or not the dynamic analysis of the dynamic image is suitable or unsuitable based on the analysis results obtained by analyzing the dynamic image, it becomes possible to objectively determine whether or not the analysis results can be used for diagnosis.

[0100] Furthermore, in the diagnostic console 3 of the second embodiment, the decision of whether or not to proceed was made based on a second characteristic quantity related to the dynamic analysis obtained from the analysis results (for example, the rate of change in lung field area). Therefore, according to the diagnostic console 3 of the second embodiment, the decision of whether or not to treat a condition can be made accurately by making the decision based on a second characteristic quantity related to the dynamic analysis obtained from the analysis results (for example, the rate of change in lung field area).

[0101] Furthermore, in the diagnostic console 3 of the second embodiment, the result of the pass / fail judgment is displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the second embodiment, the result of the pass / fail judgment is displayed on the display unit 34, allowing the user to understand the result of the pass / fail judgment.

[0102] Furthermore, in the diagnostic console 3 of the second embodiment, the analysis images of dynamic images that are deemed unsuitable based on the feasibility assessment are not displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the second embodiment, it is possible to prevent the use of analysis images of dynamic images that have been deemed unsuitable by the feasibility assessment for diagnosis.

[0103] Furthermore, in the diagnostic console 3 of the second embodiment, the analysis images of the dynamic images that were deemed suitable based on the feasibility assessment were displayed on the display unit 34. Therefore, according to the diagnostic console 3 of the second embodiment, only the analyzed images of the motion images that are deemed suitable by the feasibility assessment will be used for diagnosis, thus enabling appropriate diagnosis using the analyzed images of the motion images.

[0104] Furthermore, in the diagnostic console 3 of the second embodiment, if a judgment of unsuitability is made, notification regarding re-shooting will be issued. Therefore, according to the diagnostic console 3 of the second embodiment, if an image is deemed unsuitable, it is possible to prompt the re-capture of the motion image by providing notification regarding re-capture, thereby facilitating a series of operations related to motion analysis.

[0105] Although the first and second embodiments of the present invention have been described above, the descriptions in each embodiment are merely preferred examples of the present invention and are not limited thereto.

[0106] For example, in the first embodiment, in step S15 of the analysis feasibility determination process (see Figure 3), if it is determined that there are features that do not meet the criteria for features determined in step S13 (step S15; YES), the control unit 31 of the diagnostic console 3 displays a determination result screen on the display unit 34 that identifies that the dynamic analysis for which the criteria for the features have been determined is unanalyzable, and also displays the reason why it is unanalyzable. However, if all of the dynamic analyses determined in step S12 are unanalyzable, the dynamic images acquired from the shooting console 2 (dynamic images that are the target of the dynamic analysis) may be deleted.

[0107] Furthermore, in the second embodiment, the case in which the control unit 31 of the diagnostic console 3 performs the analysis result determination process (see Figure 7) was described as an example. However, for example, the control unit 31 may first perform the analysis feasibility determination process (see Figure 3) described in the first embodiment, and then perform the analysis result determination process described in the second embodiment for dynamic analyses that have been determined to be analyzable in this process.

[0108] Furthermore, in the first embodiment, the type of dynamic analysis is determined based on order information in step S12 of the analysis feasibility determination process (see Figure 3). However, instead of relying on the order information, the user may manually select the type of dynamic analysis desired by the user by performing a predetermined operation via the operation unit 33, for example.

[0109] Furthermore, in the first and second embodiments, the diagnostic console 3 was described as an example of a dynamic image analysis device according to the present invention. However, this dynamic image analysis device may be, for example, a PC (Personal Computer) or an image analysis terminal specifically designed for performing dynamic analysis.

[0110] Furthermore, in the second embodiment, in the analysis result judgment process (see Figure 7), the rate of change in lung field area is given as an example of the dynamic analysis subject to the process, and the feasibility judgment is made based on the rate of change in lung field area (second feature). However, for example, if blood flow analysis is performed, the control unit 31 may make the feasibility judgment based on the cardiac ROI (second feature) related to the blood flow analysis.

[0111] Furthermore, while the above description discloses examples using hard disks, semiconductor non-volatile memory, etc., as computer-readable media for the program according to the present invention, the invention is not limited to these examples. Other computer-readable media include portable recording media such as CD-ROMs. In addition, carrier waves can be used as a medium for providing the data of the program according to the present invention via a communication line.

[0112] Furthermore, the detailed configuration and operation of each device constituting the dynamic image analysis system can also be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
