We propose a motion compensation framework for 3D free-breathing abdominal MRI. This approach uses a general matrix description that incorporates motion compensation directly into the reconstruction process. The proposed method is compared with a recently introduced motion compensation technique based on image warping and the conventional gated approach. Results show the proposed approach produces images sharper than the image warping approach and gated reconstruction.
