摘要： A three-dimensional medical image is obtained, and displayed on a display screen. An input position by a user on the display screen and an input operation by the user are received. If the received input position is located in a center region of the display screen, rotation processing is performed on the three-dimensional medical image based on the received input operation. If the received input position is located in a region other than the center region, region specification processing is performed on the displayed three-dimensional medical image based on the received input operation. The region specification processing specifies a closed curve on the display screen based on the received input operation, and deletes a part of the three-dimensional medical image, and the part being an inside or an outside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.

摘要： A plurality of images for observation in different observation formats and thumbnail images corresponding to each image for observation are generated from volume data obtained for the same subject on different imaging dates/times. A plurality of image windows, which can be switched between an active state and an inactive state, are arranged on a diagnosis screen, and images for observation generated from volume data obtained on specified imaging dates are displayed in each image window. In one embodiment, thumbnail images having the same observation format as an image for observation are displayed in the vicinity of the image for observation within an image window in the active state.

摘要： A CPR image that represents a range corresponding to at least a portion of a blood vessel is generated from volume data obtained by imaging, and arranged in a predetermined region of a display screen. Band shaped condition display regions are arranged outside the predetermined region such that they are parallel to the blood vessel represented by the CPR image. Index values, such as stenosis rates and whether plaque is present, are calculated by analyzing the volume data. The calculated index values are converted to colors (RGB values) by referring to a conversion table. The condition display regions are displayed in colors according to the values of the index values.
