Claim One:
1. A method of generating motion-corrected images comprising: acquiring a plurality of acquired projections of a subject in an examination region at each of a plurality of angular orientations; reconstructing and image degrading factor correcting the acquired projections into a motion-artifacted, image degrading factor corrected image; forward-projecting and image degrading factor modeling the motion-artifacted, image degrading factor corrected image along each of a plurality of projection directions corresponding to the angular orientations of the measured projections to generate a plurality of image degrading factor modeled forward-projections; comparing the acquired projections and the image degrading factor modeled forward-projections corresponding to the same angular orientation to generate a patient motion correction vector; applying the patient motion correction vector to the acquired projections to form motion-corrected projections in a common motion state; reconstructing and image degrading factor correcting the motion-corrected acquired projections into a motion-corrected, image degrading factor corrected image.
