Expand description

HARPERELLA — integrated phase unwrapping and background removal

Estimates exterior Laplacian by enforcing uniform SMV across the FOV.

§Arguments

  • phase - Wrapped phase in radians (nx * ny * nz)
  • mask - Binary brain mask (nx * ny * nz), 1 = inside
  • grid - Volume dimensions and voxel sizes
  • params - Algorithm parameters
  • progress - Progress callback (iteration, max_iter)

§Returns

(tissue_phase, mask) — unwrapped background-free tissue phase and brain mask
