POCSMUSE is a general post-processing algorithm capable
of reducing motion-related artifacts in MRI data, using
the RF coil sensitivity profile as a constraint. It can
be applied to reduce artifacts of various patterns,
ranging from breathing-induced artifacts in abdominal
FSE imaging to aliasing artifacts due to shot-to-shot
phase variations in interleaved DWI. POCSMUSE is
compatible with existing motion artifact correction
schemes, and can be used to further improve the image
quality in data produced by existing artifact correction
procedures.
