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.
