Claim:
An image display apparatus capable of displaying a plurality of cross sectional images made from three-dimensional medical image data, comprising: a selecting unit configured to select a first position of interest and a second position of interest in a three-dimensional image; a determining unit configured to determine display switch parameters, for controlling display switching of a number of cross sectional images, by setting a transition time according to a distance between the selected first position of interest and the selected second position of interest in the three-dimensional image in one of three axial directions in which the distance is the largest such that the display switch parameter in the one axial direction becomes equal to a predetermined value, and by setting the display switch parameters in the other axial directions based on the set transition time; and a displaying unit configured to display the cross sectional images by switching the cross sectional images in parallel from the selected first position of interest toward the selected second position of interest according to the display switch parameters determined by the determining unit.
