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.
