Motion Compensated Dynamic MRI Reconstruction With Local Affine Optical Flow Estimation
Motion Compensated Dynamic MRI Reconstruction With Local Affine Optical Flow Estimation
This paper proposes a novel framework to reconstruct dynamic magnetic resonance imaging (DMRI) with motion compensation (MC). Specifically, by combining the intensity-based optical flow constraint with the traditional compressed sensing scheme, we are able to jointly reconstruct the DMRI sequences and estimate the interframe motion vectors. Then, the DMRI reconstruction …
