Abstract
Background Cardiac motion analysis can play an important role in diagnosis of cardiac disease. Tagged magnetic resonance imaging (MRI) has the ability to directly and non-invasively alter tissue magnetization and produce tag patterns on the deforming tissue [1-3]. This abstract proposes a novel optical flow method for computing the left ventricular systolic dynamics using harmonic phase (HARP) [4] images extracted from tagged MRI data.

Cardiac motion analysis can play an important role in diagnosis of cardiac disease
We have presented a novel optical flow method for cardiac motion tracking
Four physical constraints were incorporated into the optical flow energy function to obtain a robust and accurate motion field
Summary
Cardiac motion analysis can play an important role in diagnosis of cardiac disease. Tagged magnetic resonance imaging (MRI) has the ability to directly and non-invasively alter tissue magnetization and produce tag patterns on the deforming tissue [1,2,3]. Ground-truth motion fields with SinMod [5] and the proposed method.
