1. A method for compensating for motion in an imaged object, the method comprising: obtaining nuclear medicine (NM) image data for an object acquired from an NM imaging system, the NM image data including single photon emission computed tomography (SPECT) image data; performing resolution recovery on the NM image data; reconstructing the resolution recovered NM image data into a plurality of subsets; morphing the reconstructed NM image data in at least one of the plurality of subsets; normalizing the NM image data based on a magnitude of the morphing; and summing the NM image data to generate an NM image compensated for motion of the object.
