Left-ventricle myocardium segmentation using a coupled level-set with a priori knowledge

Lynch, Michael, Ghita, Ovidiu and Whelan, Paul F. orcid logoORCID: 0000-0001-9230-7656 (2006) Left-ventricle myocardium segmentation using a coupled level-set with a priori knowledge. Computerized Medical Imaging and Graphics, 30 (4). pp. 255-262. ISSN 0895-6111

This paper presents a coupled level-set segmentation of the myocardium of the left ventricle of the heart using a priori information. From a fast marching initialisation, two fronts representing the endocardium and epicardium boundaries of the left ventricle are evolved as the zero level-set of a higher dimension function. We introduce a novel and robust stopping term using both gradient and region-based information. The segmentation is supervised both with a coupling function and using a probabilistic model built from training instances. The robustness of the segmentation scheme is evaluated by performing a segmentation on four unseen data-sets containing high variation and the performance of the segmentation is quantitatively assessed.
