Module Description

DTI-Reg is an open-source C++ application that performs pair-wise DTI registration, using scalar FA maps to drive the registration.

Usage

This module is especially appropriate when one wants to map a DTI atlas to an individual subject, or to perform registration between individual subjects.

Examples

Registration from DTI source image (DTI_source.nrrd) to DTI target image (DTI_target.nrrd)

Example 1: Simple affine registration

Affine registration using BRAINS

DTI-Reg --fixedVolume DTI_target.nrrd --movingVolume DTI_source.nrrd --outputVolume DTI_source_warp.nrrd --BRAINSRegistrationType Affine

Affine registration using ANTS

DTI-Reg --fixedVolume DTI_source.nrrd --movingVolume DTI_target.nrrd --outputVolume DTI_source_warp.nrrd 
--method useScalar-ANTS --ANTSRegistrationType Affine

Example 2: Simple warping (default)

Warping using BRAINS

DTI-Reg --fixedVolume DTI_target.nrrd --movingVolume DTI_source.nrrd --outputVolume DTI_source_warp.nrrd

Warping using ANTS

DTI-Reg --fixedVolume DTI_source.nrrd --movingVolume DTI_target.nrrd --outputVolume DTI_source_warp.nrrd 
--method useScalar-ANTS

Example 3: Warping with intermediate FA maps saved as output images

Warping using BRAINS

DTI-Reg --fixedVolume DTI_target.nrrd --movingVolume DTI_source.nrrd --outputVolume DTI_source_warp.nrrd 
--outputMovingFAVolume DTI_source_FA.nrrd --outputResampledFAVolume DTI_source_FA_warp.nrrd --outputFixedFAVolume DTI_target_FA.nrrd

Warping using ANTS

DTI-Reg --fixedVolume DTI_source.nrrd --movingVolume DTI_target.nrrd --outputVolume DTI_source_warp.nrrd 
--method useScalar-ANTS
--outputMovingFAVolume DTI_source_FA.nrrd --outputResampledFAVolume DTI_source_FA_warp.nrrd --outputFixedFAVolume DTI_target_FA.nrrd
