IMAGE REGION CORRELATING DEVICE, THREE-DIMENSIONAL MODEL GENERATING DEVICE, IMAGE REGION CORRELATING METHOD, AND IMAGE REGION CORRELATING PROGRAM

摘要

An image region correlating device that correlates a plurality of image regions of a blood vessel that branches by continuously capturing images from each of a first imaging angle and a second imaging angle that are different from each other of a blood vessel (1201) through which a contrast medium is passing and acquiring a plurality of image sets constituted of first projection images from the first imaging angle and of second projection images from the second imaging angle, acquiring information about the luminance variation in the contrast medium at prescribed time intervals for a branch-point first image region (Pk) in each of the first projection images among the image sets, acquiring information about the luminance variation in the contrast medium at prescribed time intervals for each of a plurality of second image regions that are branch-point image regions in each of the second projection images among the image sets and that are candidate image regions for corresponding to the first image region, calculating the degree of similarity between the luminance variation information acquired prior and each of the plurality of pieces of luminance variation information acquired after, and designating, on the basis of the calculated degrees of similarity, the second image region that corresponds to the first image region.
