Claim:
An image display device, characterized by comprising: contour area extracting means that extracts a contour area comprising plural contour points at which a body tissue of an examinee is imaged, from a medical image obtained by imaging a hollow organ having a cavity space inside the body tissue of the examinee; radial line setting means that sets a radial center in a cavity area of the medical image in which the cavity space is imaged, sets a radial line extending from the radial center to the contour area and sets a boundary point at one point on the radial line; copy means that copies image information of a pixel that is on the radial line and inside of the boundary point to a pixel that is on the radial line and outside of the boundary point; image generating means that generates, on the basis of the copied image information of the pixel point, a reversed image in which an area at the inside of the boundary point is depicted at the outside of the boundary point; and image display means that displays the reversed image.
