Blood vessel segmentation method and device and computer storage medium

Abstract

The invention discloses a blood vessel segmentation method and device and a computer storage medium, and the method comprises the steps: obtaining and segmenting blood vessel image data, and obtainingan aorta model prediction result and a small blood vessel model prediction result; judging whether the aorta model prediction result and the small blood vessel model prediction result can be communicated into a whole or not; when the aorta model prediction result and the small blood vessel model prediction result cannot be communicated into a whole, performing coronary artery segmentation prediction on the blood vessel image data to obtain a coronary artery model prediction result; and integrating the aorta model prediction result and the small vessel model prediction result according to thecoronary artery model prediction result to obtain a normal coronary artery model prediction result. According to the coronary artery segmentation method, coronary artery region segmentation is more accurate, so that the problem that segmentation at the joint of the coronary artery and the aorta is inaccurate or even abnormal in a traditional method is solved, and a more complete and accurate coronary artery segmentation result is obtained.

Description

technical field [0001] The present invention relates to the technical field of blood vessel images, in particular to a blood vessel segmentation method, device and computer storage medium. Background technique [0002] In the field of modern medical technology, automatic coronary artery reconstruction has important clinical value and practical significance for doctors. To perform automatic coronary artery reconstruction, it is first necessary to perform CT scanning of the coronary artery, and then perform segmentation processing. [0003] In actual situations, both the coronary artery and the aorta are scanned and then segmented during coronary CT scanning, but inaccurate or even abnormal segmentation of the connection between the coronary artery and the aorta often occurs during segmentation, such as the aorta and the coronary artery. It is easy for the coronary artery and the aorta to be located outside the aorta at the coronary ostium connected by the artery, and there ma...
