Validation and Development of a New Automatic Algorithm for Time-Resolved Segmentation of the Left Ventricle in Magnetic Resonance Imaging

Figure 2

Initialization of segmentation (Step 3). The initializations of endocardial (red) and epicardial (green) borders resulting from Step 3 in the algorithm, shown in end-diastole (a) and end-systole (b) in the midventricular slice also used for Figure 1. The endocardial initialization is an estimation of the midmural line and the epicardial initialization is an estimation of the epicardial border.
