In accordance with at least some embodiments of the present disclosure, a process for enhancing a motion-blurred image is presented. The process may include obtaining a prior image based on a plurality of projections, wherein the plurality of projections are computed tomography (CT) images obtained in multiple motion phases. The process may further include performing an enhancement operation based on the prior image to generate an enhanced prior image, generating a plurality of re-projections by forward-projecting the enhanced prior image, generating a plurality of phase-correlated difference images based on the plurality of projections and the plurality of re-projections, filtering the plurality of phase-correlated difference images to generate a plurality of filtered phase-correlated difference images, and generating a plurality of phase-correlated images based on the plurality of filtered phase-correlated difference images and the enhanced prior image.
