A new POCSMUSE method is developed to produce
high-quality and artifact-free multi-shot DTI data in
the presence of large-scale intrascan subject motion,
using coil sensitivity profiles, in-plane and
through-plane position measures, and segment-specific
signal variations as constraints. The developed method
can effectively remove artifacts originating from both
in-plane and through-plane motion in multi-shot DTI
data, and is generally compatible with different types
of sampling trajectories
