Patent ID: 8384735

Claim:
An image display apparatus, comprising: image display means for displaying a two dimensional display target image, which represents a cross-sectional surface of a three dimensional image, in which the positions of each pixel are enabled to correspond to positions within an original image that represents a subject in the three dimensional image, based on the original image; structure information obtaining means for obtaining structure information, in which structure identifying information that identifies each of a plurality of predetermined anatomical structures within the subject and structure position information that represents the positions of the anatomical structures within the original image are correlated; structure identifying information specifying means for receiving specification regarding which of the structure identifying information, each corresponding to an anatomical structure, is specified as display target structure identifying information to be displayed along with the display target image; and structure position specifying means for specifying the position of the anatomical structure, which is identified by the structure identifying information, within the display target image, based on the structure information and the correspondence of positions between the original image and the display target image; wherein the structure identifying information specifying means receives specification of a group constituted by a plurality of anatomical structures, to enable specification of structure identifying information that identifies the anatomical structures included in the group as the display target structure identifying information; and the image display means displaying the display target structure identifying information along with the display target image in response to receiving the specification of the display target structure identifying information, and the display target structure identifying information is displayed within the display target image at a display position determined corresponding to the position specified by the structure position specifying means, according to a preset rule.
