Problems solved by technology

There is also a method of judging the dominance of the coronary artery based on the position of the root node of the coronary artery (left / right), and when the origin of the coronary artery, that is, the root node is abnormal, the judgment may not be accurate

Abstract

The embodiment of the invention provides a coronary artery dominant type determination method and device. The method comprises the steps of carrying out the detection of a coronary artery angiography image, and obtaining the semi-heart region information and coronary artery position information in the coronary artery angiography image, based on the coronary artery position information, determining the center line of the coronary artery, wherein the center line is a curve representing the topological structure of the coronary artery, and determining the coronary artery dominant type based on the position relationship between the neighborhood information of each point on the center line and the semi-heart region information. The method can automatically judge the dominant type of the coronary artery, is high in accuracy, can assist a doctor in diagnosing the coronary artery, and saves the workload of the doctor.

Description

technical field [0001] The present disclosure relates to the technical field of medical image processing, and in particular to a method and device for determining coronary artery dominance. Background technique [0002] The judgment of coronary artery dominance is a judgment to analyze which coronary artery (left / right) undertakes more blood supply tasks on the surface of the heart. Using Schlesinger's (Schlesinger) classification principle, the dominant type of coronary artery can include three types: right-dominant, balanced, and left-dominant. [0003] In the related art, the method for judging the dominant type of coronary arteries may be that the coronary arteries are independently segmented from the coronary angiography image, and presented to doctors in a 3D mode. Doctors can judge the dominant type of coronary arteries by themselves based on experience, and doctors need to spend extra energy to make judgments. There is also a method of judging the dominance of the ...
