ARTERY BLOOD VESSEL DETECTION DEVICE AND ARTERY BLOOD VESSEL EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an artery blood vessel detection device capable of surely extracting an artery in a short axis cross section image.;SOLUTION: An artery blood vessel detection device comprises: a compression release state determination control part 102 for determining a compression state and a release state of a biological tissue using a movement vector which indicates movement of a pixel between frames, from a moving image of a short axis cross section image; an artery blood vessel determination control part 104 for determining that the blood vessel is an artery blood vessel 20, based on a fact that, an area of a lumen N of a tubular organ which exists in the short axis cross section image in the compression state satisfies a preset artery blood vessel lumen determination condition; and an artery blood vessel tracking control part 110 for creating a template of whole artery blood vessel based on a position of the lumen of the determined artery blood vessel 20, then tracking movement of the lumen of the artery blood vessel in a step in which the short axis cross section image shifts to a release state from the compression state, using the template, then identifying the artery blood vessel in the short axis cross section image in the release state. Therefore, the artery blood vessel 20 can be accurately and automatically extracted from the short axis cross section image Ga.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2017,JPO&INPIT
