The objective of this work is to evaluate the feasibility of using non-rigid registration techniques to estimates myocardial motion from CINE-MR images without user interaction. Myocardial displacement field was obtained using a pair-wise non rigid registration technique that computes incremental motion for every consecutive pair of images in the sequence. We use a semi-local parametric deformation...
Many different techniques have been proposed to compute motion fields on Tagged MR imaging. However, most of them require tags segmentation or endo- epicardial contours segmentation. Automatic estimation of the myocardial motion field was extracted using a consecutive non-rigid registration algorithm based on a semilocal Bspline parametric model. The sequence was also represented in the Bspline space...
