Abstract: In this paper, we propose a differential surface representation for spatiotemporal tracking of myocardial deformation of the left ventricle (LV) from tagged MRI scans. The 4D tracking problem is formulated as a linear optimization function that minimizes the changes in local differential characteristics and differences between projected and tracked in-plane displacements. Compared to existing arts that fit displacements to model in separate components, the proposed method resolves the apparent motion by global and local mesh deformation considerations. The method has successfully been applied to reconstruct the motion for the LV for a set of tagged MRI scans to produce a 0.2 local linear shortening, 10.3° twist, 25% radial compression and 16% longitudinal compression.
