摘要：

In this paper, a phase based motion estimation method is presented. We also introduce a motion trajectory estimation technique. Our method is applied to cardiac motion estimation using MRI tagged image sequences. We show that our method provides roughly 15% less error than a recent motion estimation method proposed in the literature. Moreover, the estimated motion trajectories could be a good indicator of cardiac diseases.
