ABSTRACT:
A method for retrospectively correcting data prior to image reconstruction using an imaging system, wherein the method includes acquiring a first sinogram of a first slice of an object at a first axial field of view and a second sinogram of the first slice of the object at a second axial field of view different than the first axial field of view, determining at least one boundary of the object in the first sinogram and the second sinogram at the first slice, measuring a shift between the first sinogram and the second sinogram using the determined boundaries, and generating a corrected image using the measured shift.
