Expand description

Make magnitude homogeneous by dividing by bias field

This is the main entry point for bias field correction.

§Arguments

  • mag - Input magnitude data (nx * ny * nz)
  • nx, ny, nz - Dimensions
  • vx, vy, vz - Voxel sizes in mm
  • sigma_mm - Smoothing sigma in mm (default 7, will be clamped to 10% FOV)
  • nbox - Number of boxes per dimension for segmentation (default 15)

§Returns

Bias-corrected magnitude
