Abstract

This paper completely describes the fully automatic segmentation system for left ventricular myocardium segmentation from CT images by using active contour model. The system follows a coarse-to-fine strategy by first restricting the left ventricle and then damaging the myocardial surfaces of the left ventricle for segmentation. Particularly, the blood surface of a CT image is removed and illustrated as a triangular surface. Then, the ventricle is localized as a salient element on these surface victimization geometric and anatomical characteristics. After that, the heart muscle surfaces square measure initialized from the localization result and evolved by applying forces from the image intensities with a constraint supported the initial heart muscle surface locations.
