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.
Claims11
A method for processing an image of coronary arteries of a patient, comprising:
- demarcating a healthy region of the arteries and a stenosed region of the coronary arteries in the image;
- segmenting the healthy region of the coronary arteries using a level set function;
- generating a contour of the healthy region of the coronary arteries based on the segmentation;
- obtaining a first intermediate image from the contour of the healthy region of the coronary arteries;
- obtaining a second intermediate image by performing edge detection on the stenosed region;
- and
- combining the first intermediate image and the second intermediate image to obtain a composite image of a single connected component of the coronary arteries represented by a plane curve on the composite image.
A system for processing an image of coronary arteries of a patient, comprising:
- a device that:
- demarcates a healthy region of the arteries and a stenosed region of the coronary arteries in the image,
- segments the healthy region of the coronary arteries using a level set function,
- generates a contour of the healthy region of the coronary arteries based on the segmentation,
- obtains a first intermediate image from the contour of the healthy region of the coronary arteries,
- obtains a second intermediate image by performing edge detection on the stenosed region, and
- combines the first intermediate image and the second intermediate image to obtain a composite image of a single connected component of the coronary arteries represented by a plane curve on the composite image.
A non-transitory computer-readable medium storing an executable code executed on a computer for processing an image of coronary arteries of a patient, comprising:
- a computer readable program code for:
- segmenting a healthy region of the coronary arteries using a level set function, generating a contour of the healthy region of the coronary arteries based on the segmentation, obtaining a first intermediate image from the contour of the healthy region of the coronary arteries, obtaining a second intermediate image by performing an edge detection on a stenosed region of the coronary arteries, and combining the first intermediate image and the second intermediate image to obtain a composite image of a single connected component of the coronary arteries represented by a plane curve on the composite image.
