Module unwrap 

Phase unwrapping methods

Removes 2π wraps from MRI phase data.

• unwrap_romeo / unwrap_romeo_multi_echo — ROMEO, region growing with quality-guided ordering (RomeoParams)
• unwrap_bestpath — best path (3D-SRNCP), globally sorted edge merging (BestPathParams)
• unwrap_prelude — PRELUDE, best-pair-first region merging (PreludeParams); the literature’s reference unwrapper, kept as a baseline rather than a default
• unwrap_medi_region_growing — MEDI’s unwrapPhase (mexUnwrap.c, Tian Liu): magnitude-ordered region growing from the middle of the field of view, no mask, single precision, bit-identical to the MEDI toolbox
• laplacian_unwrap — Laplacian unwrapping, with a LaplacianSolver: Dct (default; unweighted least squares, Neumann BC on the array) or Fft { pad } (Schofield & Zhu sin/cos method on the zero-padded volume, which reproduces STI Suite 3.0’s MRPhaseUnwrap)

All of the above read across slice boundaries. For a 2D multi-slice acquisition, where each slice carries its own receive phase offset, run one of them per slice with unwrap_slicewise / unwrap_slicewise_multi_echo (SliceWiseParams).
