Method for estimating degree of arterial occlusion

Disclosed herein is a method for estimating a degree of arterial occlusion in a subject. The method comprises: (a) providing a plurality of image frames of an artery of the subject taken in sequence; (b) selecting a plurality of cross-sections of the artery based on the plurality of image frames of...

Zusammenfassung:Disclosed herein is a method for estimating a degree of arterial occlusion in a subject. The method comprises: (a) providing a plurality of image frames of an artery of the subject taken in sequence; (b) selecting a plurality of cross-sections of the artery based on the plurality of image frames of the step (a), and determining a maximum diameter and a minimum diameter of each of the plurality of cross-sections of the artery among the plurality of image frames; (c) calculating an average vasodilation ratio of the artery base on the maximum diameter and the minimum diameter of each the plurality of cross-sections of the artery determined in the step (b); and (d) determining the degree of arterial occlusion of the artery based on the average vasodilation ratio calculated in the step (c).
