Abstract

A method for locally correcting motion in an image reconstructed by a reconstruction system (42) of an imaging system (10) with raw data includes estimating a characteristic feature of a region of interest within the reconstructed image from the raw data, correcting the raw data associated with the region of interest for motion with the estimated region characteristic feature, and reconstructing a motion-corrected image corresponding to the region of interest with the corrected raw data.
