Abstract:
1. A method, comprising: (a) determining a motion correction estimate for projection data corresponding to a volume of interest (VOI) in a functional image of a subject based on the VOI; (b) motion correcting the projection data corresponding to the VOI with the motion corrected estimate to generate current motion corrected projection data; (c) estimating at least one kinetic parameter value based on the current motion corrected projection data, wherein the at least one kinetic parameter value; is a current kinetic parameter value: (e) determining a next motion correction estimate for the current corrected projection data corresponding to the VOI based on the VOI; (f) motion correcting the current corrected projection data corresponding to the VOI with the next motion corrected estimated to update the current motion corrected projection data; (g) setting the current motion corrected projection data equal to the updated current motion corrected projection data; and (h) estimating a next kinetic parameter value based on the current motion corrected projection data.
