Abstract

The invention discloses a blood vessel center line extraction method and device. The method comprises the following steps: carrying out refining treatment on a predetermined blood vessel by adopting a topological refining mode to obtain an initial center line of the predetermined blood vessel; starting from a root node of the initial center line, performing segmentation marking on the initial center line to obtain a preprocessed center line; and performing redundant segment deletion operation on the preprocessed center line to obtain a target center line of the predetermined blood vessel. According to the method, the technical problem of low reliability of a blood vessel center line extraction mode in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of computer-aided medical treatment, in particular to a method and device for extracting a blood vessel centerline. Background technique [0002] At present, in the study of computer-aided diagnosis of coronary artery disease, segmentation of coronary arteries and extraction of coronary artery centerlines are the primary tasks of research. Accurate contours and centerlines can establish accurate vascular tree models, and can obtain accurate stenosis and calcification, etc. The disease coefficient can better assist doctors in clinical diagnosis and treatment. When extracting the centerline of blood vessels, judging the quality of an algorithm usually depends on the following indicators: whether the skeleton is broken, whether the skeleton can retain the topological information of the blood vessel, whether the skeleton is centered, whether the width of the skeleton is 1, etc. [0003] Since the coronary branc...
