Abstract

The invention discloses a coronary artery recognition method and device. One embodiment of the method comprises the following steps: acquiring two quasi-center lines of a coronary artery; calculatingthe minimum distance from each measurement point on the two quasi-center lines to the left ventricle, the left atrium, the right ventricle and the right atrium respectively to obtain a first distance,a second distance, a third distance and a fourth distance correspondingly; sorting the first distance, the second distance, the third distance and the fourth distance corresponding to each measurement point from small to large; selecting left coronary artery feature points and right coronary artery feature points from all the measurement points on the two quasi-center lines based on the sorting result of each measurement point, and counting the number of the left coronary artery feature points and the right coronary artery feature points on each quasi-center line; and determining whether thecoronary artery corresponding to the quasi-center line is the left branch or the right branch based on the number of the left coronary artery feature points or the number of the right coronary arteryfeature points. Therefore, the accuracy of coronary artery left and right branch identification is improved.

Description

technical field [0001] The invention belongs to the technical field of medical imaging, and in particular relates to a coronary artery identification method and device. Background technique [0002] In modern medicine, in order to identify the left and right branches of the coronary artery, it is usually based on the point coordinates on the centerline of the coronary artery and combined with a specific algorithm to accurately identify the left and right branches of the coronary artery. [0003] However, due to variations in coronary arteries when lesions occur, it is difficult to identify the left and right branches of coronary arteries with traditional identification methods for some mutated coronary arteries. In order to improve the accuracy of identifying the left and right branches of the coronary artery, it is urgent to provide a more robust method for identifying the left and right branches of the coronary artery to meet the diagnostic needs of patients.
