摘要:A method for retrospectively correcting data prior to image reconstructionusing 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 theobject at a second axial field of view different than the first axial field of view, determiningat least one boundary of the object in the first sinogram and the second sinogram at thefirst slice, measuring a shift between the first sinogram and the second sinogram usingthe determined boundaries, and generating a corrected image using the measured shift.
