Analytic signal phase-based myocardial motion estimation in tagged MRI sequences by a bilinear model and motion compensation
We propose a phase-based motion estimation method for tagged MRI sequences. The proposed method has subpixel accuracy and is robust to intensity variation. Our method reduces 33% estimation errors compared with two outstanding methods. The deformation and the local region tracking of the myocardium are presented. Our estimation results on clinical cases are well coherent to medical diagnosis.
