IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire many-sided and useful information regarding the medical treatment of aneurysm or the like.

SOLUTION: The central point 0 of a CT cross section of a blood vessel part is determined from a CT tomographic image of the blood vessel. Then, a blood vessel part central line C is formed by interpolating an area from the central point 01 to 0n of respective adjacent blood vessel part CT cross sections with a smooth curve in a first step. A blood vessel part vertical section which is vertical to the central line C is formed for each micronic zone of the central line C, and at the same time, the contour shape of the blood vessel vertical section is approximated with a polygonal shape in a second step. The length of the blood vessel wall is determined by accumulate-adding micro distances which are determined for spaces between respective apices of the adjacent polygonal cross sections in a third step. This image processing method comprises those three steps.
