The multi-breath-hold approach with slice/slab tracking enables high resolution abdominal MRI, but artifacts derived from nonuniform receive coil sensitivity still remains. We developed a novel technique to reduce residual motion artifacts using information entropy as a cost function to optimize correction phase. This method remarkably reduced artifacts in phantom and volunteer studies without explicit knowledge of coil sensitivity.
