A blood vessel segmentation method, device and computer storage medium

Abstract

The invention discloses a blood vessel segmentation method, equipment and computer storage medium. The method includes: acquiring and segmenting blood vessel image data, obtaining the prediction result of the aorta model and the prediction result of the small blood vessel model; judging the prediction result of the aorta model and Whether the prediction results of the small blood vessel model can be connected as a whole; when the prediction results of the aorta model and the prediction results of the small blood vessel model cannot be connected as a whole, perform coronal segmentation prediction on the blood vessel image data to obtain A prediction result of the coronary ostium model; integrating the prediction result of the aorta model and the prediction result of the small vessel model according to the prediction result of the coronary ostium model to obtain the prediction result of the normal coronary artery model. The invention makes the segmentation of the coronary ostium area more accurate, thereby overcoming the inaccurate or even abnormal segmentation of the joint between the coronary artery and the aorta in the traditional method, thereby obtaining a more complete and accurate coronary artery segmentation result.

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...
