A new approach for the extraction of the myocardium from MR cardiac scans is presented. Segmentation and recognition of the left ventricle by a sequence of generic image processing operations is carried out in an order determined by a model of domain-specific relational, spatial, and morphological knowledge of the cardiac images. In particular, a new technique for constrained surface deformation by variable morphological dilation is introduced. These methods, incorporated in a prototype system called CARDIAN, have produced encouraging results in initial experiments with MR scans from phantom, dog, and human studies.
