    摘要: A method and system for automatically associating coronary arteries with regions of the myocardium to which the arteries supply blood is described. The method uses three dimensional image data of a patient, and an axial image slice is used to identify candidate locations of the aorta. Candidate aorta centroid locations are evaluated to eliminate spurious identifications, and the identified aorta is used to locate the left ventricle of the heart with respect thereto. Arteries of the coronary artery tree may be located by segmentation of contrasted images, and the individual arteries may be identified by skeletonization of the segmented arteries. The skeletonized arteries are projected onto an image of the patient heart, and may be associated with specific regions of the myocardium.
