Registration and model-based analysis of transaortic valvular flow ultrasound images

Detecting changes in the contractility of the heart muscle, especially in the presence of coronary artery disease, is an important medical task. To test whether there is a relationship between the morphology of the aortic outflow velocity profile and myocardial function a segmentation of the aortic outflow velocity profile is necessary as well as the morphology feature extraction. Our approach is based on atlas-based image segmentation that utilizes specially formulated geometrical transformation, image similarity measure, atlas formation and segmentation propagation. Following atlas-based image segmentation, various cardiac parameters are extracted to describe morphological properties of transaortic valvular flow.
