An imaging system enables cardiac functioning within a particular cardiac chamber to be imaged. The system acquires imaging data that includes intensity values for four-dimensional voxels within a region of interest (ROI). A seed voxel is identified, and neighbor voxels to the seed voxel are also identified....http://www.google.de/patents/US6438403?utm_source=gb-gplus-sharePatent US6438403 - Method and apparatus for cardiac analysis using four-dimensional connectivity
