We propose a new reconstruction technique tailored for
free-breathing dynamic 3D liver MRI by estimating the
motion between frames to correct inconsistencies in
k-space data. Our approach produced results that
demonstrate it is feasible to achieve a 10x speedup in
acquisition time and remove motion artifacts without
diminishing image quality. The proposed method produced
gains up to 3 dB with respect of traditional CS
framework.
