Abstract
In this paper, anatomical characteristic of convexity of left ventricles (LV) is incorporated in the level set segmentation framework to improve the accuracy of the algorithm. In order to maintain the convexity of endocardial and epicardial contour, we use the two-layer level set model combined with periodical convexification of the level sets, which eliminates the troublesome interference caused by the papillary muscle and the trabeculae. We use the MICCAI 2009 left ventricle segmentation challenge data to test and validate our method. Qualitative experiments demonstrate the effectiveness of our algorithm.
