Abstract
The positions where back-projection lines from a plurality of images pass through a predetermined voxel slice of a 3D space are calculated. Letting a predetermined one of the plurality of images be defined as a basic image and the other remaining images as reference images, information about back-projection lines from the basic image is stored in a basic back-projection line information storage part and information about the back-projection lines from the reference images are stored, as information associated with voting, in a voting information storage part. A count is taken of reference back-projection lines which pass through the same passing position of each basic back-projection line, and this count value is used to update the information about the basic back-projection line. After execution of each processing in all voxel slices of the 3D space, the information about the basic back-projection line information is read out of the basic back-projection line information storage part.
