Description

[Technical Field]

[0001] The present invention relates to a display control device, a display control method, and a display control program. [Background technology]

[0002] As efforts are made to utilize radiographic images from radiography for diagnosis of various cases, various analytical processes have been developed and put into operation, and the variety of analytical processes is increasing. As a result, multiple types of analytical images are generated from a single radiographic image, and it becomes necessary for the technicians who provide the radiographic images and the doctors who check the radiographic images to search for and confirm the appropriate analytical process from among the wide variety of analytical processes.

[0003] For example, Patent Document 1 discloses a configuration in which a priority is set for each analysis result for each disease of the subject, and a list of images based on the set priority is displayed.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described in detail with reference to the accompanying drawings. Fig. 1 is a block diagram showing an image display system 1 including a display control device according to an embodiment of the present invention.

[0013] 1, image display system 1 is a system capable of displaying images (radiation images) generated by a modality (not shown). Image display system 1 includes HIS (Hospital Information Systems) 11, RIS (Radiology Information Systems) 12, console 13, PACS (Picture Archiving and Communication Systems) 14, and image analyzer 15. These can communicate with each other via communication network 16.

[0014] The modality may be, for example, a radiographic imaging device capable of generating dynamic images composed of multiple frame images, or may be capable of generating still images. The modality may be connected to the communication network 16 via the console 13. Images may be transferred from the modality to the image display system 1 via the console 13, or may be transferred using a storage medium or a cable.

[0015] The HIS 11 and the RIS 12 store examination information. The examination information may be, for example, the type of imaging (such as the type of modality used, whether the patient is in an upright or supine position), the area to be imaged, the name of the medical department requesting the examination, the age and sex of the subject, and the name of the operator. Based on a request from another device (such as the console 13, the PACS 14, or the image analyzer 15), the HIS 11 and the RIS 12 transmit the requested examination information to the other device.

[0016] The console 13 is configured as a PC (Personal Computer) or a dedicated device, etc. The console 13 sets various imaging conditions (tube voltage, tube current, irradiation time (mAs value), frame rate, etc.) for modalities, etc., based on examination information acquired from other devices (HIS 11, RIS 12, etc.) or operations by the operator. The console 13 also controls the start and end of imaging, acquires captured images, and outputs the captured images to the PACS 14 and image analyzer 15.

[0017] The PACS 14 is composed of a PC or a dedicated device, etc. The PACS 14 is equipped with a database, and stores data such as still images or dynamic images acquired from modalities in the database. In addition, based on a request from another device (console 13, image analyzer 15, etc.), the PACS 14 selects image data, etc. stored in the database, and transmits the requested image data, etc. to the other device.

[0018] Image analysis device 15 is a device capable of displaying images based on operations by an operator, such as a PC, a mobile terminal (e.g., a tablet terminal or a smartphone), or a dedicated device, and analyzes still images or dynamic images acquired from a modality via console 13. Image analysis device 15 corresponds to the "display control device" of the present invention.

[0019] The image analysis device 15 includes a control unit 110, a communication unit 120, a storage unit 130, and a display unit 140.

[0020] The control unit 110 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The CPU of the control unit 110 reads a program corresponding to the processing content from the ROM and loads it into the RAM. The control unit 110 then cooperates with the loaded program to centrally control the operation of each unit.

[0021] The communication unit 120 is configured with a wireless module or the like, and transmits and receives various signals and various data to and from other devices connected via the communication network 16 .

[0022] The control unit 110 acquires image data of a radiographic image generated by a modality via the communication unit 120. After acquiring the image data, the control unit 110 analyzes the image data and generates an analysis image that is the analysis result of the image data.

[0023] The analysis images may include, for example, blood flow analysis images, structure analysis images, ventilation analysis images, adhesion analysis images, diaphragm movement amount analysis images, and orthopedic-related measurement images. The analysis images may also include abnormality detection images showing areas where abnormalities have been detected, analysis summary images, past comparison images showing comparisons with past images, and past time-lapse difference images showing time-lapse differences from past images. The analysis images may also include images that have not been subjected to analysis processing but are used for comparison with images that have been subjected to analysis processing, such as original images and past images taken in the past. The analysis images may also include images based on analysis processing other than the examples described above.

[0024] The control unit 110 stores these analysis images in the storage unit 130.

[0025] These analysis images are displayed on the display unit 140 after analysis by the control unit 110, and are then confirmed by the user. Users include, for example, doctors such as radiologists and clinicians, technicians of radiological imaging devices, and assistants to doctors or technicians.

[0026] When multiple analysis results are stored as described above, the user must select the image they want to check from among the multiple analysis results. This selection operation requires the user to stop the work they are currently doing, which can be time-consuming for the user.

[0027] Therefore, in this embodiment, the control unit 110 sets the display order of a plurality of analysis results for a radiographic image on the display unit 140. The control unit 110 corresponds to the "setting unit" of the present invention.

[0028] The control unit 110 may set the display order according to the combination of elements included in the examination information, imaging information, and the like, for example.

[0029] The examination information includes, for example, information on the medical department related to capturing the radiological image and information on the purpose of the examination. The medical department may be any department that uses radiological images for diagnosis, such as emergency medicine, respiratory medicine, thoracic surgery, or cardiology. The purpose of the examination may be any purpose, such as screening, chronic obstructive pulmonary disease (COPD), pneumothorax, or postoperative monitoring.

[0030] The imaging information includes information on the examination site of the subject, information on whether or not previous examinations have been performed, information on the imaging direction, information on the number of images taken, etc. The examination site may be any site, such as the chest, thoracic and abdominal regions, as long as it is a site that can be examined using a radiographic image. The imaging direction may be any direction, such as the front or side, as long as it is a direction from which a radiographic image can be taken.

[0031] For example, suppose that the department in charge of the subject to be radiographed is a respiratory medicine department, the purpose of the examination is screening, and the chest and abdomen are imaged from the front. In this example, suppose that the control unit 110 generates an adhesion analysis image and a ventilation analysis image as analysis results for the original image taken by radiography.

[0032] In this case, the control unit 110 sets the display order to, for example, the original image, ventilation analysis image, and adhesion analysis image.

[0033] As a result, when the user checks the analysis results on the display unit 140, the analysis results are displayed on the display unit 140 in the order of the original image, ventilation analysis image, and adhesion analysis image.

[0034] As shown in Fig. 3, switching of images on the display unit 140 may be performed, for example, by the user operating a switching button 141 provided on the screen of the display unit 140. Specifically, when the user causes the display unit 140 to display the analysis results, the original image ("Original" in Fig. 3) is displayed first. When the user presses the switching button 141 to perform a switching operation, the display on the display unit 140 is switched from the original image to a ventilation analysis image (ventilation analysis in Fig. 3). Then, when the user presses the switching button 141 to perform a switching operation, the display on the display unit 140 is switched from the ventilation analysis image to an adhesion analysis image (adhesion analysis in Fig. 3).

[0035] This saves users the trouble of searching for the image they want to check among multiple analysis results.

[0036] Furthermore, switching of images on the display unit 140 may be performed automatically over time, or may be performed by a user operation other than the operation of the switching button 141. For example, an operation other than the operation of the switching button 141 may be an operation to switch all of the images displayed as the nth image when there are multiple images displayed as the nth image (any natural number). After this operation is performed, the image to be displayed as the n+1th image is displayed on the display unit 140. For example, an operation other than the operation of the switching button may be an operation to slide an image within the screen of the display unit 140 when the display unit 140 is of a touch panel type. Furthermore, switching of images on the display unit 140 may be performed when two types of analysis images are displayed, after all frames or a specific frame range of an analysis image based on one of the dynamic images has been displayed.

[0037] Furthermore, if a dynamic image is included in the analysis results, the operation other than the operation of the switching button may be an operation to play the dynamic image. After the playback of the dynamic image is completed, the display on the display unit 140 is switched to the next image to be displayed.

[0038] Furthermore, if a dynamic image is included in the analysis result, the dynamic image displayed on the display unit 140 may be played back by a user operation or automatically.

[0039] Furthermore, after all of the analysis results set in the display order have been displayed on the display unit 140, the analysis result that was displayed first may be displayed again on the display unit 140. In other words, after all of the multiple analysis results have been displayed on the display unit 140 in the set display order, the control unit 110 may display the multiple analysis results again on the display unit 140 sequentially in that display order.

[0040] For example, assume that the display order is set as described above in the order of original image, ventilation analysis image, and adhesion analysis image. In this case, after the original image, ventilation analysis image, and adhesion analysis image are displayed in sequence, the original image is displayed again on the display unit 140. Furthermore, if a dynamic image is included in the analysis results set in the display order, all frames of the dynamic image may be displayed in the first display, and only some frames of the dynamic image may be displayed in the second display or later display.

[0041] The display order set by the control unit 110 may be an order according to a preset diagnostic flow. The preset diagnostic flow may be, for example, a diagnostic flow set for each facility.

[0042] For example, if there are multiple radiologists at a facility, differences in the experience of the radiologists in charge can lead to variations in diagnostic results. Therefore, by defining a diagnostic flow on a facility-by-facility basis, even inexperienced radiologists can check the analysis results in the appropriate display order.

[0043] The preset diagnostic flow may be a diagnostic flow set for each medical department.

[0044] For example, if the department is an emergency department, the urgency is relatively high, so it is necessary to check the abnormality detection image at an early stage.In contrast, in departments other than the emergency department, even if an abnormality is detected, it is preferable to understand to some extent the parts other than the detected abnormality, so the abnormality detection image may be checked at a later stage.Furthermore, in cases such as respiratory surgery, where the purpose is to monitor postoperative progress, past comparison images are necessary.

[0045] For these reasons, the diagnostic flow differs depending on the medical department, so by defining the diagnostic flow for each medical department, the analysis results can be displayed on the display unit 140 in an appropriate display order for each medical department.

[0046] The preset diagnostic flow may be a diagnostic flow set for each user. That is, the control unit 110 may set a first display order for a first user and a second display order for a second user as the display orders for the first user and the second user, respectively.

[0047] For example, if the user is a radiologist, the user needs to look through all of the multiple analysis results. However, if the user is a clinician, the user will focus on problem areas and will relatively rarely look at all of the multiple analysis results, so it is thought that there is very little need to use the same display order as a radiologist.

[0048] For these reasons, by defining a diagnostic flow for each user, the efficiency with which users can check analysis results can be improved.

[0049] In addition, the diagnostic flow for each facility, department, or user may be set by initial settings, or may be set by changing the initial settings of the diagnostic flow of the device through editing operations by the user.

[0050] 4, the control unit 110 may control the display unit 140 to simultaneously display a plurality of analysis images based on a plurality of analysis results on the screen. For example, the plurality of analysis images are displayed in an A×B display. A indicates the number of images arranged horizontally, and B indicates the number of images arranged vertically.

[0051] Furthermore, the control unit 110 may set a combination of analysis images to be simultaneously displayed on the screen of the display unit 140 according to the content of the analysis images.

[0052] For example, an image that has undergone analytical processing, such as a ventilation analysis image, can be easily compared if it is displayed simultaneously with the original image. Therefore, the control unit 110 controls the display of the original image and the image that has undergone analytical processing in a 2x1 display. Figure 4 shows an example in which the original image and the ventilation analysis image are displayed in a 2x1 display.

[0053] This makes it easier for the user to check the analysis image, and also reduces the number of times the analysis results need to be switched, thereby shortening the time it takes to check the analysis results.

[0054] Furthermore, if the analysis images displayed simultaneously are images with different diagnostic purposes, such as a ventilation analysis image and a blood flow analysis image, the display on the display unit 140 may become cluttered and difficult for the user to see.

[0055] Therefore, the control unit 110 may set an analysis image that is not displayed simultaneously on the screen of the display unit 140.

[0056] This can prevent the display from becoming difficult for the user to see.

[0057] Furthermore, the control unit 110 may set a plurality of patterns of display orders with different combinations of elements of the examination information and the imaging information, and store these in the storage unit 130. Fig. 5 shows an example of data in which a plurality of patterns of display orders are associated with combinations of elements of the examination information and the imaging information.

[0058] The first display in Fig. 5 is the display image that is displayed first. The second display is the display image that is displayed second. Also, Fig. 5 shows an example in which there are only two display orders, the first display and the second display, but there may be three or more display orders.

[0059] Specifically, if the department is respiratory medicine and the purpose of the examination is COPD, the imaging information includes the chest as the area and the front and side as the directions, which are combined with each element of the examination information. The first display contains the front original image and the front ventilation analysis image in a 2x1 display, and the second display contains the side original image and the side ventilation analysis image in a 2x1 display.

[0060] In addition, if the department is thoracic surgery and the purpose of the examination is postoperative progress monitoring, the imaging information will be combined with each element of the examination information, such as the chest area, previous examinations, and the direction as front.The first display will display the original image and previous comparison image in a 2x1 format, and the second display will display the ventilation analysis image and previous temporal subtraction image in a 2x1 format.

[0061] By doing so, multiple display patterns can be prepared in advance, and multiple analysis results can be displayed on the display unit 140 in an appropriate display order at the timing when various users want to check them.

[0062] The control unit 110 selects one of a plurality of display patterns stored in the storage unit 130, for example, based on the identification information of a user (e.g., a clinician) checking the display unit 140. Specifically, the control unit 110 selects the appropriate display pattern based on information about the medical department to which the user belongs.

[0063] In this way, a plurality of analysis results can be displayed on the display unit 140 in an appropriate display order suited to the user.

[0064] Furthermore, if the user checking the display unit 140 is an image-reading doctor, the department to which the image-reading doctor belongs may differ from the department that requested the examination of the subject. For example, if the department that requested the examination of the subject is a respiratory surgery department, but the department to which the image-reading doctor belongs is a radiology department, the department to which the image-reading doctor belongs will differ from the department that requested the examination.

[0065] In this case, the control unit 110 may select one of a plurality of patterns of display order based on information accompanying a plurality of analysis results.

[0066] The information accompanying the multiple analysis results may be, for example, examination information or imaging information.

[0067] For example, since the examination information includes information about the medical department that requested the examination, the control unit 110 selects a display pattern corresponding to the relevant medical department from the medical department information. Also, when the relevant medical department is a respiratory medicine department and the imaging information includes only information about a front image in terms of the imaging direction, the control unit 110 selects a display pattern corresponding only to information about the front image.

[0068] In this way, a plurality of analysis results can be displayed on the display unit 140 in an appropriate display order corresponding to the analysis results.

[0069] The processing performed by the control unit 110 according to this embodiment configured as above will now be described. Fig. 6 is a flowchart showing an example of the processing performed by the control unit 110.

[0070] 6, the control unit 110 acquires image data from a modality (step S101). After acquiring the image data, the control unit 110 executes image analysis processing on the image data (step S102). After executing the image analysis processing, the control unit 110 sets the display order of multiple analysis results (step S103).

[0071] After setting the display order, the control unit 110 sequentially displays the analysis results on the display unit in the set display order (step S104). After step S104, this control ends.

[0072] According to the present embodiment configured as described above, the display order of the multiple analysis results for the radiation image on the display unit 140 is set, and the multiple analysis results are controlled to be displayed sequentially on the display unit 140 in multiple batches according to the display order.

[0073] This eliminates the need for users to manually select the analysis results they want to display when checking multiple analysis results, reducing the amount of work required for users to view multiple analysis results.

[0074] In addition, the control unit 110 sets the display order so that it follows a predetermined diagnostic flow, so that the user can check the analysis results that need to be confirmed in the appropriate display order and at the necessary timing.

[0075] Furthermore, for example, a diagnostic flow can be fixed for a specific case, thereby reducing the workload caused by switching between displays.

[0076] Furthermore, since the diagnostic flow including the display order can be standardized, it becomes easier to share the viewpoints of doctors.

[0077] Furthermore, by fixing the diagnostic flow, it becomes easier to specify the analysis images to be prepared in advance, which reduces the cost of generating images.

[0078] In addition, the control unit 110 controls the display unit 140 to simultaneously display multiple analysis images based on multiple analysis results on the screen of the display unit 140, and sets the combination of analysis images to be simultaneously displayed on the screen of the display unit 140 depending on the content of the analysis images.

[0079] This makes it easier for users to check the analysis image. It also reduces the number of times the analysis results are switched, shortening the time it takes to check the analysis results. It also prevents the display from becoming difficult for users to see, as analysis images that are not simultaneously displayed on the screen are set depending on the content of the analysis image.

[0080] Furthermore, the control unit 110 selects one of multiple display order patterns based on the identification information of the confirming user who confirms the radiological image, and thus multiple analysis results can be displayed on the display unit 140 in an appropriate display order corresponding to the user.

[0081] Furthermore, the control unit 110 selects one of multiple patterns of display order based on information accompanying the multiple analysis results, and therefore, the multiple analysis results can be displayed on the display unit 140 in an appropriate display order corresponding to the analysis results.

[0082] In the above embodiment, the elements of the examination information used to set the display order are information on the medical department and information on the purpose of the examination, but the present invention is not limited to this. For example, the examination information used to set the display order may include elements such as information on the subject's gender, age, physique, and medical history. Each piece of information on the subject may be information read from the subject's electronic medical record, information entered by the user, etc.

[0083] In this way, the display order can be different for each subject, so that the user can check the analysis results in a display order that is suitable for the subject.

[0084] In the above embodiment, the elements of the imaging information used to set the display order are information on the examination site of the subject, information on whether or not previous examinations have been performed, information on the imaging direction, and information on the number of images taken, but the present invention is not limited to this. For example, the imaging information used to set the display order may include elements related to imaging method information, such as information on breathing techniques (breath holding, forced breathing, natural breathing, etc.).

[0085] In this way, analysis images specific to the imaging method can be displayed in an appropriate display order, which improves ease of confirmation by the user.

[0086] In the above embodiment, the display order is set according to the elements included in the examination information and the imaging information, but the present invention is not limited to this. For example, since the types of analysis processing and machine learning available vary depending on the facility, the display order may be set according to the type of analysis processing and machine learning.

[0087] In the above embodiment, the display order is set according to a predetermined flow regardless of the results of the analysis process, but the present invention is not limited to this. For example, the control unit 110 may change the display order according to a predetermined flow in accordance with the results of the analysis process, the results of case estimation by CAD processing, etc.

[0088] Specifically, it is possible to add or change the display objects that are simultaneously displayed on the display unit 140. Furthermore, when analysis and determination are performed by machine learning, the display order may be set so that the user can select the image to be displayed next based on the analysis results.

[0089] This allows the display order to reflect the results of the analysis process, etc., further improving the ease of confirmation by the user.

[0090] Furthermore, when the analysis image is a dynamic image, the control unit 110 may perform control based on the analysis content to select an initial display frame of the dynamic image and display it on the display unit 140. Specifically, for example, a frame in which an abnormality is detected, a frame in which the maximum exhalation volume or the maximum inhalation volume is reached in a dynamic image of breathing, a frame that is the starting point of the subject's movement in a dynamic image for shaping purposes, or the like may be selected as the initial display frame.

[0091] This allows the frames to be checked in the dynamic image to be initially displayed, so that the user can quickly check important frames without having to play back the entire dynamic image.

[0092] Furthermore, the control unit 110 may set the first frame of the dynamic image as the initial display frame regardless of the analysis content.

[0093] This allows the user to thoroughly check the dynamic image.

[0094] Now, suppose that a user finds an important frame (hereinafter referred to as an important frame) to be checked while checking a predetermined dynamic image. In this case, since the user knows the location of the important frame in the dynamic image displayed next to the predetermined dynamic image, it is considered preferable to quickly display the frame corresponding to the important frame of the predetermined dynamic image in order to reduce the checking time.

[0095] Therefore, when a user sets a setting to annotate a specific frame in a first dynamic image among multiple dynamic images, the control unit 110 may change the setting of the initial display frame of a second dynamic image, which is displayed later than the first dynamic image, to a frame related to the specific frame.

[0096] The setting for adding an annotation is a setting operation performed by the user via an operation unit or the like, such as adding a mark to a specific frame in a dynamic image, and any setting operation may be used as long as the control unit 110 can identify the specific frame. The specific frame may be an image that is easiest to diagnose the case among all frames, or an image that displays a characteristic point such as adhesion. In addition to the above-mentioned marking operation, the setting operation that allows the control unit 110 to identify the specific frame may also include an operation of adding an arrow, an operation of drawing a rectangle, an operation of adding a comment to the specific frame, etc.

[0097] The frame related to the specified frame may be a frame in the second dynamic image corresponding to the same location as the specified frame in the first dynamic image, or a frame several frames before the frame corresponding to the same location as the specified frame.

[0098] For example, if a user considers the 10th frame to be an important frame while playing the first dynamic image and sets the annotation to be added to the 10th frame, when the second dynamic image is played, the initial display frame is set to, for example, the 10th frame.

[0099] This makes it possible to reduce the overall time required to check dynamic images.

[0100] In a case where multiple people are reviewing analysis results, and a diagnostic flow is set for each user, if the first user (first user) to review the analysis results finds an abnormality in a specific analysis image, it can be inconvenient for a subsequent user (second user) to review the analysis results if the analysis image in which the abnormality was detected is preset to be displayed later, as the analysis image the user wants to review quickly will be displayed later.

[0101] Therefore, the control unit 110 may change the display order set for the second user from the second display order based on confirmation information of the plurality of analysis results based on the first display order by the first user. The first display order is the display order set for the first user, and the second display order is the display order set for the second user.

[0102] For example, suppose that in a given facility, a first radiologist first checks the analysis results, followed by a second radiologist. A display order for the first radiologist is set for the first radiologist, and a display order for the second radiologist is set for the second radiologist. The multiple analysis results include a first analysis result, a second analysis result, a third analysis result, and a fourth analysis result. The first display order is the display order in which the first analysis result, the second analysis result, the third analysis result, and the fourth analysis result are displayed on the display unit 140 in this order. The second display order is the display order in which the second analysis result, the third analysis result, and the fourth analysis result are displayed on the display unit 140 in this order.

[0103] In this case, it is assumed that the first radiologist determines that an abnormality has been detected in the third analysis result. At this time, the first radiologist inputs the third analysis result as confirmation information into image analyzer 15 or the like via the operation unit. When the second user confirms the analysis result, control unit 110 changes the display order set by the second user from the second display order to the third analysis result, the second analysis result, and the fourth analysis result based on this confirmation information.

[0104] This allows the display order for the second user to be flexibly changed to a display order that reflects the confirmation result of the first user who has confirmed it first.

[0105] In addition, in the above embodiment, a plurality of analysis images are displayed side by side on the screen of the display unit 140, but the present invention is not limited to this. For example, a plurality of analysis images may be displayed on the display unit 140 in a superimposed manner.

[0106] For example, in blood flow analysis, to check the state of the subject's left lung, two analysis images may be displayed superimposed on each other so that the left halves of the two blood flow analysis images are aligned. Also, analysis images whose analysis results do not interfere with each other (e.g., structural analysis and ventilation analysis images) may be displayed superimposed as layers.

[0107] In the above embodiment, although a display order is set, if the user does not understand the display order, the user may not be able to know which analysis result will be displayed next when the analysis results are switched, but the present invention is not limited to this. For example, control unit 110 may display information about a second analysis image that will be displayed after the currently displayed first analysis image on display unit 140 simultaneously with the first analysis image.

[0108] For example, Fig. 7 shows an example in which information about a second analysis image is displayed below a first analysis image (original image) on the display screen. In Fig. 7, information indicating that the next image to be displayed is a "ventilation analysis" is shown as an example of information about the second analysis image.

[0109] Furthermore, in the above embodiment, a 2x1 display was shown as an example of displaying multiple analysis images simultaneously, but the present invention is not limited to this, and displays other than a 2x1 display, such as a 2x2 display (see Figure 8), may also be used.

[0110] Furthermore, in the above embodiment, the image analysis device 15 is exemplified as the display control device, but the present invention is not limited to this, and other devices such as the PACS 14 may be the display control device.

[0111] In the above embodiment, the display control device is a device (image analysis device) having a display unit, but the present invention is not limited to this and may be a device without a display unit. This device may be configured to acquire analysis results, etc., analyzed by the image analysis device, set a display order, and display the analysis results in the set display order on a separate display device.

[0112] Furthermore, the above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be carried out in various forms without departing from the gist or main features thereof. [Explanation of symbols]
