Claim Text:
1. A three-dimensional image processing apparatus, comprising: a memory configured to store data of a plurality of projected images, which is photographed from different directions in a first three-dimensional coordinates system, regarding a stent inserted into a subject body; a coordinates acquisition circuit configured to acquire three-dimensional coordinates regarding two stent markers given to a central axis of the stent, based on two-dimensional coordinates of the two stent markers and photographing directions regarding two projected images of the plurality of projected images; a coordinates transformation circuit configured to set a second three-dimensional coordinates system having three orthogonal axes, wherein one axis of the three orthogonal axes is a straight line connecting the three-dimensional coordinates of the two stent markers, the second three-dimensional coordinates system being a three-dimensional orthogonal coordinates system that is translated and/or rotated with respect to the first three-dimensional coordinates system; and a reconstruction circuit configured to reconstruct three-dimensional image data by defining voxels in the second three-dimensional coordinates system from the plurality of projected images.
