Abstract

The invention discloses a method and a system for evaluating coronary artery segmentation. The evaluation method comprises the following steps: extracting the centerline of the predicted coronary artery segmentation to obtain the predicted centerline; generating a marker centerline by using a marker partition; comparing the prediction centerline with the marker centerline to determine an abnormalposition present in the prediction centerline; an evaluation index of the coronary artery segmentation is determined based on the determined abnormal position. The method and system can effectively evaluate the abnormalities of coronary artery segmentation by reflecting the noise, fracture and false trend of coronary artery segmentation in the process of automatic coronary artery reconstruction.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a coronary artery segmentation evaluation method and system. Background technique [0002] In the past 50 years, the incidence of coronary heart disease has continued to rise globally, and interventional therapy, surgery and drug treatment for coronary heart disease have developed rapidly. Both doctors and patients have a dependence and expectation on the surgical treatment of coronary heart disease, which can be seen from the increasing number of patients with coronary artery revascularization around the world, and this technique has been widely accepted and recognized. Therefore, coronary artery reconstruction has become the most commonly used and most important method in the treatment of coronary artery disease, which has important clinical value and practical significance. [0003] However, in the process of automatic coronary artery reconstruction, DicLoss is used a...
