DTI Registration & Resampling Wizard

Objective

This project intends to build a dedicated module/wizard for the common case of registering and resampling a DTI image set to a structural reference scan, commonly a high-resolution T1.

Approach, Plan

The algorithms for the necessary processing (registration, sub/supersampling, DTI estimation, DTI resampling) already exist within Slicer. But the parameters and GUIs of the individual modules are non-intuitive and not readily accessible to the clinician researcher. We therefore seek a wizard module that compiles the main pipeline and default settings into a single GUI. This is a "DTI registration light" that will not offer the full range of customization available in the individual modules and hence is not expected to work on the full spectrum of possible case scenarios.

  • input: DWI volume or DTI volume incl. baseline and mask
  • output: Affine+BSpline registration transform, resampled DTI volume
  • use the BRAINSfit module for registering the DTI baseline to the T1 directly
  • use the masking option avail. in BRAINSfit. Masks for the moving image is derived from the DTI estimation; mask for the fixed image from the same image sent through a preliminary affine registration
  • resampling of the DTI is done via the main algorithm in the Resample DTI Volume module
