Abstract

Accurate delineation of the volumetric motion of left ventricle (LV) of the heart over time from tagged MRI is an important area of research. We have built a system that takes tagged short-axis (SA) and long-axis (LA) image sequences as input, fits a 4D B-spline model to the LV of the heart by simultaneously fitting knot solids to the SA and LA frame sequences via matching 3 sequences of model knot planes to LV tag planes for 4D tracking. The advantage of the 4D model is that 3D material point localization and displacement reconstruction is achieved in a single step. The generated 3D displacement fields are validated with a cardiac motion simulator, and 3D motion fields capturing in-vivo deformations in a parcine model of a LV with postero-lateral myocardial infarction are illustrated.
