Simultaneous extraction of endocardial and epicardial contours of the left ventricle by distance regularized level sets

Purpose: Segmentation of the cardiac left ventricle (LV) is still an open problem and is challenging due to the poor contrast between tissues around the epicardium and image artifacts. To extract the endocardium and epicardium of the cardiac left ventricle accurately, the authors propose a two-layer...
