Image area associating device, a three-dimensional model generating device, image area mapping methods, and image area mapping program

摘要

A blood vessel (1201) at the time when the contrast agent passes therethrough is successively imaged from first and second imaging angles different from each other, and the first projection image at the first imaging angle and the second imaging angle A plurality of image sets each including a contrast medium for a predetermined period of time for the first image region (Pk) as a branch destination in the first projection image among the image sets, For each of a plurality of second image regions which are image regions of a branch destination in the second projection image among the respective image sets and which are candidate image regions corresponding to the first image region , The information on the luminance change of the contrast agent for a predetermined time is acquired respectively and the similarity between the information on the previously acquired luminance change and the information on a plurality of luminance changes obtained later is calculated, And determines a second image region corresponding to the first image region on the basis of the degree of similarity and associates a plurality of image regions of a blood vessel having a branch.
