摘要

PROBLEM TO BE SOLVED: To combine SPECT (Single Photon Emission Computed Tomography) images in which motion of a heart containing a twist has been eliminated from electrocardiogram synchronous SPECT images.

SOLUTION: A SPECT image processor 100 comprises: a storage unit 11 for storing an electrocardiogram synchronous SPECT image composed of a plurality of phase images where one cycle of heartbeat has been divided into a plurality of segments and photographed by using an electrocardiogram synchronous SPECT; a motion vector calculation unit 13 for employing two phase images of phases adjacent to each other regarding a plurality of phase images stored in the storage unit 11 to calculate motion vector groups showing motion of a heart between the two phases, for motion between all phases; and an image combination unit 17 for combining a plurality of phase images into one combined SPECT image by employing a plurality of phase images stored in the storage unit 11 and a plurality of motion vector groups calculated by the motion vector calculation unit 13.
