In this work, we extend multiplexed sensitivity-encoding
(MUSE) to address the issues related to shot-to-shot
large-scale motion. Our method groups shots into
clusters, reconstructs each cluster with MUSE by taking
advantage of the same magnitude property inside each
cluster, and corrects the inter-shot motion by image
registration techniques. The proposed can robustly
deliver high quality image even when there is large
scale inter-shot motion.
