Heart modeling and segmentation. (a) Heart surfaces including four chambers and attached large vessels are modeled by subdivision surfaces, where white dots are control vertices. The LV wall is generated by warping the mid-surface using the thickness explicitly defined. (b) Segmented heart boundaries shown on the views of four chambers, left two chambers, two ventricles and left ventricular outflow tract. Three borders are used to divide the endocardium and epicardium for the LV wall.
