(Image list screen display)
The image list display device 1 first causes the monitor 3 to identify and display a list of medical images and a graphical image representing the attributes of the medical images. The graphical image is an image indicating which imaging part is an image of a medical site to be displayed in a list and an image indicating which image type.

  FIG. 3 is a schematic diagram showing a list display screen displayed on the monitor 3. As shown in FIG. 3, the display screen is divided into a list display area 21 and a graphical image display area 22.

  In the list display area 21, a list of medical images is displayed. The list is a list in which examination information character strings 211, series information character strings 212, and image identification information character strings 213 of medical images are used as list display items, and the list display items are represented in a hierarchy. The examination information character string 211 is a character string for classifying examinations, and is, for example, a shooting date. The series information character string 212 is a character string for classifying the series, and is, for example, a series number and the number of images included in the lower layer. This series is classified by the imaging method, imaging site, image type, presence / absence of image processing, and the like. The image identification information character string 213 is a character string representing a UID that identifies a medical image.

  FIG. 4 is an enlarged schematic view of the graphical image portion of the list display screen. As shown in FIG. 3 or 4, a human body image 221 and a type display image 222 are displayed in the graphical image display area 22. The human body image 221 is a graphical image imitating the whole image of the human body. The type display image 222 is a graphical image representing the image type of a medical image. For example, a non-contrast image (a in FIG. 4), a contrast image (b in FIG. 4), an MPR image (c in FIG. 4), a volume image (d in FIG. 4), a three-dimensional image, and a four-dimensional image (in FIG. 4) e).

  The human body image 221 is displayed by identifying an imaging region of a medical image to be displayed in a list on a model image. For example, if an image obtained by photographing the head, the lower limbs, and the upper abdomen is present in the medical image to be displayed in a list, the head (f in FIG. 4), the lower limb (g in FIG. 4), and the upper abdomen ( In FIG. 4, h) is identified and displayed. If there is no image in which the chest and lower abdomen are captured in the medical image to be displayed in a list, the chest (i in FIG. 4) and the lower abdomen (j in FIG. 4) are not identified and displayed. This presence identification display is such that a portion corresponding to a photographing portion of a medical image is painted in a predetermined color, highlighted, or the like. The predetermined color is a color for recognizing that there is a medical image obtained by photographing the painted portion, and is predetermined in blue, red, or the like.

  The type display image 222 corresponding to the image type of the medical image to be displayed in a list is identified and displayed so as to be distinguished from other type display images 222. For example, if a medical image to be displayed in a list includes a non-contrast image, a contrast image, and a four-dimensional image, a type display image 222 (a, b, e in FIG. 4) representing these images is identified and displayed. The various display images representing the MPR image (c in FIG. 4) and the volume image (d in FIG. 4) are grayed out. This presence identification display is a case where the color of the frame of the type display image 222 is set to a predetermined color, highlighted display, or the like. The predetermined color is a color for recognizing that there is a medical image having an image type corresponding to the type display image that is identified and displayed, and is predetermined in blue, red, or the like.

  FIG. 5 is a schematic diagram of a graphical image portion showing that there are a plurality of medical images of the same imaging region and the same image type. If images of the same imaging region exist in a plurality of medical images to be displayed in a list, the region on the human body image 221 corresponding to the imaging region is identified and displayed by a different display method. If there are images of the same image type in a plurality of medical images to be displayed in a list, the type display image 222 corresponding to the image type is identified and displayed by a different display method. For example, if there are a plurality of medical images in which the head and upper abdomen are imaged, the head (f in FIG. 5) and the upper abdomen (h in FIG. 5) of the human body image 221 are the lower limbs (g in FIG. 5). Is further displayed with a different display method. If there are a plurality of contrast images and MPR images in the medical images to be displayed in a list, the contrast display images and MPR image type display images 222 (b and d in FIG. 5) are converted into non-contrast image and MPR image type display images 222 (in the drawing). Identification and display are performed by a display method different from a and c).
