We present a new technique to enable high-quality and
artifact-free abdominal MRI data. The developed ReKAM
module incorporates bootstrapping in k-t space and
multiplexed sensitivity encoding to produce high-quality
image. The ReKAM module can effectively remove
motion-related artifacts resulting from global and local
motion during free-breathing abdominal MRI scan, without
navigator echo or any pulse sequence modification.
