Objective
We are developing methods to study the connectivity of the developing brain in humans and macaques. The goals for this project week is the development of 1)a visualization strategy of ODF/HARDI information in Slicer (work with Bloy/Verma/Westin) and 2)a global fiber tractography method using HARDI/ODF information. Long-term goals of the project include application of the tractography results for deformable registration purposes and study of connectivity patterns in brain development.
Approach, Plan
- Compare and select the most appropriate higher order diffusion representation for our human and macaque data from early brain development DWI studies
- Visualization (development/implementation of modules for Slicer3), in collaboration with Bloy/Verma/Westin
- Fiber tractography and connectivity information analysis
Progress
We have the matlab implementation of various QBall techniques and have applied those techniques to neonatal human data and primate data. We're also learning to use the CAMINO package and its use for our purpose. We just started the development for the global fiber tractography.
