Free Water Elimination (FWE) for Diffusion MRI

Overview

Implements free water elimination (FWE) models for preprocessing diffusion MRI data.

---

Available Models

• Free water DTI as implmented in dipy (Hoy et al., 2014)
• Beltrami regularized gradient descent free water DTI (Golub et al., 2020)

Example

from fwe import free_water_elimination

free_water_elimination(
  dwi_fname    = "sub-01_dwi.nii.gz",
  bval_fname   = "sub-01.bval",
  bvec_fname   = "sub-01.bvec",
  mask_fname   = "sub-01_mask.nii.gz",
  fwe_model    = "dipy_fwdit",
  output_fname = "sub-01_fwe.nii.gz"
)
