Computation Of Left Ventricular Motion Patterns Using A Normalized Parametric Domain

Impairment of left ventricular contractility due to cardiovascular diseases is reflected in the regional motion patterns. Computation of such patterns can help in the detection and localization of any cardiac disorder. In this paper we introduce, a general framework, that we call normalized parametric domain, that allows comparison of vectorial data obtained from several patients. We address both, extraction of the LV motion from tagged magnetic resonance sequences, as well as, defining a mapping of the LV to a common normalized domain. Motion patterns are built from 21 healthy volunteers and correlations with tissue structure is explored.
