Abstract

A misregistration correction system that corrects for artifacts generated by the movement of a subject being imaged during the interval between temporally separated images. The system reduces the effects of secondary characteristics on the determination of a vector between a point on a first image and a point on a second image, which vector delineates the motion of the subject.
