Sulcal depth overlayed on inflated cortical surfaces

Key Investigators

  • UNC: Clement Vachet, Heather Cody Hazlett, Martin Styner

Objective

We would like to create end-to-end applications within Slicer3 allowing voxel-based and mesh-based group analyses of cortical thickness.

Such a workflow applied to the young brain (2-4 years old) is our goal in order to start a longitudinal study of early brain development in autism (UNC DBP).

See our Roadmap for more details.




Approach, Plan

Our approach is described in the following wiki pages:

Two 3D Slicer high-level modules -directly available as extensions- have been developped in that regard:

Our plan for the project week is to improve GAMBIT's overall distribution:

  • Include/Improve download/compilation of external packages
  • Improve ShapeWorks integration within Slicer3 (meeting with SCI members)

Progress

  • Attended the Particle Shape Correspondence Breakout
    • ShapeWorks will be available soon as a SVN repository on NITRC (from CVS on GForge) and directly integrated within 3D Slicer as an extension
  • GAMBIT now includes download/compilation of external packages: ABC, ShapeWorks, BRAINSFit, BRAINSResample, BRAINSDemonWarp...

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a:

  1. ITK Module
  2. Slicer Module
    1. Built-in
    2. Extension -- commandline - YES
    3. Extension -- loadable
  3. Other (Please specify)
