1. A method to enhance a motion-blurred image, comprising: receiving a plurality of projections, wherein the plurality of projections contain computed tomography (CT) data obtained in multiple motion phases; generating a multi-phase image based on the plurality of projections; generating an enhanced multi-phase image by performing a destreaking operation on the multi-phase image to reduce one or more motion-induced artifacts in the multi-phase image; generating a plurality of re-projections by forward-projecting the enhanced multi-phase image; generating a plurality of difference projections by comparing the plurality of projections and the plurality of re-projections; generating a plurality of phase-correlated difference images by performing a reconstruction operation based on the plurality of difference projections; and generating a plurality of phase-correlated images based on the plurality of phase-correlated difference images and the enhanced multi-phase image.
