Expand description

Truncated k-space division (TKD) for dipole inversion

Computes susceptibility map from local field using direct k-space division with threshold-based truncation.

§Arguments

  • local_field - Local field values (unwrapped phase / TE / gamma / B0)
  • mask - Binary mask (1 = inside ROI, 0 = outside)
  • grid - Volume grid (dimensions and voxel sizes)
  • bdir - B0 field direction (bx, by, bz)
  • params - TKD parameters (truncation threshold)

§Returns

Susceptibility map (same size as input)
