Let the measured (wrapped) phase be where is an
n-dimensional index specifying the spatial location (or voxel). The
objective is to find the unwrapped phase denoted such that:
|
(1) |
where the integer value at each voxel specifies the corrective
offset required. The unwrapped phase should be smooth and not contain
the jumps that are typically seen in the wrapped phase.
