The underlying goal is to understand the physiology of heart disease. We present here a novel method to compute the 2D-deformation field of the heart (rat or human) from tagged MRI. Previous work is not suitable for wide clinical use for different reasons, including important computing time and lack of robustness. We propose an original description of tags as local minima of 1D signals. This leads us to a new formulation of the tag tracking problem as an Extrema Temporal Chaining (ETC) and a 2D-rendering. 2D-displacements are then interpolated on a dense field. The developed method is fast and robust. Its performances are compared to those of HARP, a leading method in this field.</p> Motion Estimation Crest Line Grid Image Medical Research Project Noninvasive Magnetic Resonance Imaging Dewey 616.0757 Springer Berlin, Heidelberg Lecture Notes in Computer Science (LNIP) 4179 Swiss National Science Foundation Advanced cardiac Magnetic Resonance Imaging for myocardial hibernation 68778 CH Careers 62 Département de radiologie et informatique médicale 227 false 286 Imagerie cardiaque fonctionnelle 541 Advanced Concepts for Intelligent Vision Systems Jacques Blanc-Talon, Wilfried Philips, Dan Popescu, Paul Scheunders 8th International Conference, ACIVS 2006, Antwerp, Belgium, September 18-21, 2006, Proceedings 18-21 septembre 2006 Antwerp (Belgium) 886d4341-11d1-4597-abbb-59c241e81e19 Proceedings chapter (Published version) Restricted EXTREMA TEMPORAL CHAINING A NEW MET.pdf 166792 application/pdf 1c8d04038b893d366c5de294dbfdd21d6b263e6b8b3f4079436d5a7a60ca87ef restrictedAccess Faculté de médecine / Section de médecine clinique / Département de radiologie et informatique médicale
