May enable refined LV motion tracking in cardiac MRI; hypothesis-generating and requires prospective validation before clinical use.
Presents a novel computational framework using two-dimensional harmonic estimation and sequential filtering for the temporal analysis of left ventricular wall motion from cardiac MRI.
McEachen et al. (2002) studied Left ventricular endocardial wall motion. Recursive filter for temporal analysis was evaluated on Temporal analysis of left ventricular endocardial wall motion. A recursive filter using two-dimensional harmonic estimation and flow vector computation successfully modeled the periodic nature of cardiac motion in magnetic resonance images.
