摘要

By radiating X-rays of the same intensity from the blood vessel (1201) when the contrast medium passes through the first and second imaging angles, the first and second X-ray images are captured by the X-ray image acquisition unit (11) For the first image region corresponding to the blood vessel portion in the first X-ray image, the absorption characteristic acquisition part (12) acquires the absorption characteristic of the X-ray from the luminance of the contrast agent in the blood vessel part in the second X-ray image For each of a plurality of second image regions which are corresponding image regions and which are candidate image regions corresponding to the first image region, the absorption characteristics of X rays are obtained from the brightness of the contrast agent as absorption characteristic acquisition parts (13), calculates the similarity between the acquired absorption characteristics by the similarity calculation unit (14), respectively, and calculates the second image area having the highest similarity in the area corresponding to the first image area If there is, the corresponding area determining unit (15) determines it.
