Objective
To incorporate into Slicer, processing and analysis methods for DTI and HARDI being developed at the Section of Biomedical Image Analysis (SBIA), UPenn [1]. The main components will be plugins for DTI registration and manifold-based statistics followed by methods for HARDI registration and statistics.
Approach, Plan
- DTI registration: has been developed in SBIA over a period of 2 years, mainly using in-house code (not in ITK). This will be incorporated as a plugin.
- DTI Statistics: SPM-like package for statistics on the full tensor. The proposed format is again a plugin as it is based on code already existing in SBIA in C, C++.
- HARDI registration: This is being developed in ITK, building on HARDI representation format currently under development
- HARDI statistics: being developed in ITK
Progress
- DTI Registration: plugin is ready and will be demonstrated
To do: Replace the affine registration component, help file, speed, version control
- Need help with:
1. General representation for registration in ITK 2. Code for Demons DTI registration for comparison 3. Visualization: tensor glyphs and ODFs
