3D left ventricular segmentation using double active contours and double active surfaces

We propose a 3D left ventricular segmentation method for cardiac MR images. There are two steps in our method. In the first step, we improve our double active contours for segmenting the endocardial and the epicardial boundaries simultaneously without requiring any training sets. In the second step, we designed a double active surface method to segment the volume within the endocardium and the thickness of the myocardium simultaneously from a set of 2D contours generated from the first step. Our results show successful simultaneous segmentation of the 3D left ventricular model of the heart.
