Problems solved by technology

Since the method will include some non-coronary blood vessels in the segmentation of candidate coronary artery components, the ability to segment and identify the ends of blood vessels is not strong enough, resulting in a decrease in the accuracy of the segmentation results

Abstract

The invention relates to an image processing, in particular to a coronary artery segmentation method and device. The method comprises the following steps: segmenting and expanding a cardiac region through a cardiac segmentation model to obtain a coronary artery region; segmenting and predicting the coronary artery region by a coronary artery model to obtain a coronary artery prediction result; based on at least one endpoint on the coronary artery prediction result, optimizing the endpoint on the coronary artery prediction result by a coronary artery optimization model to obtain a coronary artery sub-region optimization prediction result; splicing the optimized prediction results of coronary artery sub-region on the corresponding endpoints of the prediction results to obtain the optimized prediction results of coronary artery segmentation, which improves the segmentation accuracy of coronary artery.

Description

Technical field [0001] The present invention relates to image processing technology, in particular to a coronary artery segmentation method and device. Background technique [0002] To maintain the normal life activities of various tissues and organs of the human body, the heart needs to be constantly beating to ensure blood circulation. The aorta is the largest artery. It originates from the heart and is responsible for the blood supply to the whole body. As a muscular power organ for pumping blood, the heart itself also needs sufficient nutrition and energy. Coronary arteries are blood vessels dedicated to nutrition for the heart. They originate from the root of the aorta and are divided into left and right branches and run on the surface of the heart. Both are emitted from the heart and supply oxygen and nutrients to the organs. [0003] At present, people have developed many kinds of cardiovascular imaging technologies to visually view the structure of coronary arteries aroun...
