Improve myocardial strain estimation based on deformable groupwise registration with a locally low-rank dissimilarity metric

Abstract Background Current mainstream cardiovascular magnetic resonance-feature tracking (CMR-FT) methods, including optical flow and pairwise registration, often suffer from the drift effect caused by accumulative tracking errors. Here, we developed a CMR-FT method based on deformable groupwise re...
