Abstract

Artifacts due to patient motion in the slice-selection direction (Z motion) have been a major source of MR image degradation for many years but have not been addressed as much as in-plane motion due to the complexity of modeling and correcting for the motion. In this paper we present a model and a detection and correction scheme for amplitude aberrations due to motion in the slice-selection direction. 1.
