Probabilistic cardiac atlas. A labeled probabilistic atlas was used to provide prior knowledge of the cardiac anatomy during the segmentation process. Multiplanar reconstructions of the atlas are shown where each voxel is assigned a probability of belonging to left ventricular blood pool (yellow), left ventricular wall (green), right ventricle blood pool (red) and background (blue). (A) Left ventricular short axis. (B) Vertical long axis. (C) Horizontal long axis.
