<p>Structures in the vicinity of a target point (point of interest) within a diagnostic image are enabled to be observed in detail from multiple directions. Overview images (8, 9) that represent the overview of a structure (e.g., the large intestine) are generated based on volume data, and displayed on the screen (5) of a display. Points within the overview images and points corresponding thereto in the volume data are set as target points. Target volumes that include the target points and line of sight vectors within the volume data having the target points as endpoints and a movable viewpoint as a starting point are set within the volume data. The directions of the line of sight vectors are changed, and the target volumes are projected onto projection planes perpendicular to the directions of the line of sight vectors to generate detailed images (11) that represent details of the structure in the vicinity of the target points. The detailed images (11) which are generated accompanying changes in the line of sight direction are displayed sequentially or alongside each other on the screen.</p> |
