Further, the image processing control unit 15b outputs and stores the image data of the processing result in the image processing unit 13 to the storage unit 14 or the portable recording medium 5.

  Next, a display screen (GUI screen) displayed on the display unit 12 by the image display device 4 will be described. FIG. 3 is a diagram illustrating an example of a GUI screen that the image display device 4 displays based on control by the image display control unit 15a. As shown in FIG. 3, the display unit 12 displays a window 21 (“diagnosis / diagnosis” window) as a GUI screen. In the window 21, a main display area 22 for displaying a main display image and the like, an image operation area 25 for displaying various image operation buttons shown as icons, and a time scale indicating an imaging period of a series of in-subject images. The color bar 26 and the time bar 27 and the sub display area 28 for displaying thumbnail images and the like are displayed in parallel on the display screen from the top to the bottom in this order.

  In the main display area 22, a main display image 23 which is an image selected from a series of in-subject images based on instruction information input from the input unit 3, and antennas 6 a to 6 on the subject 1. An antenna arrangement diagram 24 schematically showing the arrangement of 6h is displayed. In the main display area 22, the name, ID number, gender, age, date of birth, imaging date of the subject 1 associated with the in-subject image selected as the main display image 23, The imaging time and the like are displayed as character information. In the main display area 22, a predetermined number of main display images of two or more can be displayed according to a predetermined operation.

  Antenna arrangement FIG. 24 schematically shows the arrangement of the antennas 6 a to 6 h together with a partial outline of the subject 1. In addition, in the antenna arrangement diagram 24, the antenna number as the identification number of each antenna is displayed in the vicinity of the antennas 6a to 6h. For example, in FIG. 3, “1” to “8” are shown as antenna numbers. In the antenna arrangement diagram 24, when the in-subject image displayed as the main display image 23 is captured, the maximum strength antenna having the highest reception strength among the antennas 6a to 6h is displayed so as to be distinguishable from other antennas. . For example, FIG. 3 shows a state in which the antenna of antenna number “4” is displayed as the maximum strength antenna so as to be distinguishable from other antennas. As an identifiable display, the image display control unit 15a can display, for example, at least one of display brightness, display hue, display saturation, and the like of the maximum intensity antenna differently from other antennas.

  The color bar 26 displays the average color of each image included in the series of in-subject images as a whole in time series. That is, in the display area at each time point on the color bar 26, the average color of the in-subject image captured at this time point is displayed. Since a series of in-subject images have a specific average color according to the imaged organ, the observer or the like can determine from the transition of the average color along the time axis (horizontal axis in FIG. 3) on the color bar 26, It is possible to easily determine the organ imaged in the in-subject image at each time point.

  In addition, the color bar 26 is configured by dividing the entire display area into four parts in the vertical direction on the display screen, and the divided color bar at each divided stage includes a series of divided images of the in-subject image. The area average color or period area average color of each corresponding step in the area is displayed in time series. That is, the average color of each in-subject image is calculated for each divided image area obtained by dividing the entire image area into four parts in the vertical direction, and the color bar 26 has a divided scale obtained by dividing the display area at each time point into four parts in the vertical direction. For each region, the region average color or period region average color of each divided image region associated with the division order is displayed.

  According to the color bar 26, the observer can not only determine the organ imaged in the in-vivo image at each time point from the transition of the average color along the time axis of the divided color bar of each divided stage. The state inside the imaged organ can be easily estimated in detail according to the divided image region. Thereby, for example, when an average color of red color is visually recognized in the uppermost divided color bar 26a in a certain period, the observer or the like has confirmed that there is a bleeding site inside the organ imaged in this period, It can be recognized that there is a bleeding site in the imaging range corresponding to the uppermost divided image region in the in-subject image. Further, for example, an organ in the imaging range excluding the lumen portion is displayed by displaying the black average color of the image region including the lumen portion and the average color of the other image region on the divided color bar. The internal state can be recognized.

  The time bar 27 displays a slider 27 a that can move in the time axis direction on the time bar 27. The slider 27 a indicates on the time bar 27 the imaging time point of the in-subject image displayed as the main display image 23 and moves on the time bar 27 in conjunction with the display switching of the main display image 23. For example, when any image operation button in the image operation area 25 is operated by a mouse or the like (not shown), the main display image 23 is switched and displayed, and the slider 27a is displayed as the main display image 23 after the switching display. It moves to a position that indicates the time point at which the in-subject image is captured.

  On the other hand, when the slider 27a is moved by a mouse (not shown) or the like, the in-subject image corresponding to the imaging time pointed by the slider 27a after the moving operation is displayed as the main display image 23. . When the slider 27a is continuously moved, the main display image 23 is continuously switched and displayed following the moving operation. According to the slider 27a, the observer or the like moves the slider 27a to an imaging time point corresponding to the in-subject image of the desired organ found with reference to the color bar 26, for example. The main display image 23 can be displayed immediately.

  Further, on the time bar 27, a marker 27b indicating an imaging period of an image group recognized as a noticed image from a series of in-subject images is displayed so as to be distinguishable from other display areas on the time bar 27. . For example, in FIG. 3, the marker 27b is displayed in a color different from that of other display areas, and can be easily visually recognized by an observer or the like.

  The start time (the time at the left end of the marker 27b) and the end time (the time at the right end of the marker 27b) of the imaging period indicated by the marker 27b are determined by the landmark button 29 as an operation icon for adding the label information to the in-subject image. Set by operation. That is, the in-subject image at the time of imaging that is the start time of the marker 27 b is displayed as the main display image 23, and a click operation or the like with a mouse (not shown) is performed on the landmark button 29. The label information indicating the start time is added to the in-subject image. Similarly, the in-subject image at the time of imaging, which is the end time of the marker 27b, is mainly displayed, and the landmark button 29 is operated to add label information indicating the end time to the main-displayed in-subject image. Then, when the start time point and the end time point are set in this way, a marker 27b that clearly indicates the designated imaging period is displayed.

  According to the marker 27b, an observer or the like can easily recognize that the in-subject image within the imaging period indicated by the marker 27b is a particularly noticeable image. Further, by recording the information of the marker 27b, that is, the label information indicating the start time and the end time of the marker 27b in association with the in-subject image, the target image is displayed each time this series of in-subject images is displayed. The existing imaging period can be displayed, the time and labor required for image search by an observer or the like can be reduced, and the attention image can be observed efficiently.

  Note that the left end of the color bar 26 and the time bar 27 as time scales indicates the time point when the first image is captured in time series in the series of in-subject images, and the right end indicates the time point when the last image is captured in time series. Show. Normally, the leftmost imaging time corresponds to the start of reception of image data by the receiving device 3, and the rightmost imaging time corresponds to the end of reception of image data.

  In the sub display area 28, images selected and extracted from a series of in-subject images are displayed as thumbnail images 28a. Specifically, for example, in response to a predetermined button operation or mouse operation, the in-subject image displayed as the main display image 23 at the time of this operation is additionally displayed in the sub display area 28 as a thumbnail image 28a. .

  In the sub display area 28, individual additional information is displayed as character information 28b in the vicinity of each thumbnail image. As the character information 28b, an imaging time of each thumbnail image to be displayed, a relative time based on a predetermined time corresponding to the imaging time, a comment added by an observer, and the like are shown. For example, the character information 28b in FIG. 3 indicates the relative time corresponding to the time point when each thumbnail image is taken with reference to the time point when the first image is taken in time series.

  In the display of the relative time, the reference time can be changed according to a predetermined operation. Specifically, for example, by clicking on one of the displayed thumbnail images, the thumbnail image to be operated is displayed. The imaging time can be used as a reference for relative time. For example, in the character information 28b ′ shown in FIG. 4, as a result of clicking the thumbnail image 28a-n, the relative time reference (time “00:00:00”) is changed to the time of capturing the thumbnail image 28a-n. ing.

  By displaying the relative time on each thumbnail image in this way, the observer can roughly predict the imaging position of the thumbnail image of interest within the subject. Specifically, for example, when an image including a lesioned part is observed with reference to the imaging time of the in-vivo image starting to image the small intestine, based on the relative time of the image, the small intestine start position is used as a base point. The position of the affected part can be estimated.

  The text information 28b and 28b 'displayed in the sub display area 28 can be switched between information contents to be displayed according to a predetermined operation and can be hidden. Further, in the sub display area 28, a line segment in which each thumbnail image is associated with the time point at which each thumbnail image is displayed on the time bar 27 is displayed.

  In addition, since the size of the display area is limited in the sub display area 28, up to a predetermined number of thumbnail images 28a can be collectively displayed. For example, FIG. 3 shows a case where a maximum of five thumbnail images can be displayed at once. When the number of extracted thumbnail images 28a is larger than a predetermined number that can be collectively displayed, the thumbnail images exceeding the predetermined number are switched and displayed according to the operation of the scroll bar 28c displayed in the sub display area 28. Each thumbnail image displayed in the sub display area 28 is displayed as a main display image 23 in response to a predetermined button operation or mouse operation.

  Here, a processing procedure of the landmark setting process as a process in which the image display device 4 according to the present embodiment displays a marker on the time bar 27 will be described. FIG. 4 is a flowchart showing a landmark setting processing procedure. As shown in FIG. 4, the image processing control unit 15b determines whether or not the landmark button 29 has been operated as a determination of the start of the landmark setting process (step S101). (S101: No), this determination process is repeated at a predetermined cycle.

  On the other hand, when the landmark button 29 is operated (step S101: Yes), the image display control unit 15a displays a landmark setting dialog for acquiring the details of the sign information (step S102). In step S102, the image display control unit 15a performs control to display the landmark setting dialog 30 so as to overlap the window 21, for example, as shown in FIG.

  In the landmark setting dialog 30 shown in FIG. 5, “feature area start” as an item for setting the marker information indicating the start time of the marker shown on the time bar 27 and the marker information indicating the end time are set in the same manner. “End of feature area” as an item to be set, “No setting” as an item for which neither setting is performed, and “Relative time reference as an item for setting a reference for relative time as character information added to the thumbnail image 28a” "Is displayed and one of the items is selected.

  In the landmark setting dialog 30, an “OK” button for confirming the selected item and a “cancel” button for canceling the setting operation by the landmark setting dialog 30 are displayed. When the “OK” button or the “Cancel” button is operated, the landmark setting dialog 30 is automatically closed after predetermined processing.

  Next, the image display control unit 15a determines whether or not a setting item has been selected on the landmark setting dialog 30 (step S103), and if selected (step S103: Yes), setting of the set item is performed. The contents are temporarily stored (step S104). On the other hand, when the setting item is not selected (step S103: No), the process proceeds to step S105. The determination process in step S103 may be performed when a predetermined time has elapsed since the execution of step S102.

  Subsequently, the image display control unit 15a determines whether or not the “OK” button has been operated on the landmark setting dialog 30 (step S105). If the “OK” button has been operated (step S105: Yes), the selected setting is performed. The marker information is updated according to the item (step S106), and the marker is displayed on the time bar 27 based on the updated marker information (step S107). Thereafter, the updated sign information is recorded in the storage unit 14 (step S108), and the process proceeds to step S111.

  On the other hand, when the “OK” button is not operated (step S105: No), the image display control unit 15a determines whether or not the “cancel” button is operated on the landmark setting dialog 30 (step S105). S109) If not operated (step S109: No), the processing from step S103 is repeated. When the “Cancel” button is operated (step S109: Yes), all the processes related to the landmark setting process are canceled (step S110), the landmark setting dialog 30 is closed (step S111), and this series The landmark setting process is terminated.

  In step S107, the image display control unit 15a has the item selected on the landmark setting dialog 30 "start characteristic area", and the object associated with the label information in the series of in-subject images. If there is no other in-sample image, for example, as shown in FIG. 6, the display area on the time bar 27 before the imaging time of the in-subject image associated with the label information is displayed by the marker 27c. To do.

  In step S107, the image display control unit 15a determines that the image display control unit 15a has the selected item “end of characteristic region” and the label information is associated with a series of in-subject images. If there is no other in-sample image, for example, as shown in FIG. 7, the display area on the time bar 27 after the imaging time of the in-subject image newly associated with the label information is displayed by the marker 27d. To do.

  Further, in step S107, the image display control unit 15a determines that the selected item is “characteristic region start” (or “characteristic region end”), and the end point (or start point) in the series of in-subject images. When there is an in-subject image associated with the label information indicating, a display area sandwiched in accordance with each index information on the time bar 27 is displayed by the marker 27b, for example, as shown in FIG. indicate.

  As described above, in the image display device 4 according to the present embodiment, the marker 27b indicating the imaging period of the image group recognized as the target image is displayed on the time bar 27 indicating the imaging period of the series of in-subject images. ˜27d and the like are displayed so as to be distinguishable from other display areas on the time bar 27, so that an observer or the like can easily recognize the imaging period in which the image of interest exists, and the image of interest is displayed for each observation.
