Abstract

The present invention relates to a system and a method for processing an initial image of coronary arteries. In accordance with the proposed method, a healthy region and a stenosed region of said arteries are first demarcated in the initial image. A first intermediate image is obtained by generating a contour of said healthy region of said arteries by segmentation of said healthy region using a level set function. A second intermediate image obtained by performing edge detection on said stenosed region. The first and second intermediate images are then combined to obtain a composite image of a single connected component represented by a plane curve on said composite image.
