2011 Winter Project Week:GAMBITCorticalThicknessAnalysis

• 

  Projects List

• 

  ARCTIC: Automatic Regional Cortical ThICkness

• 

  GAMBIT: Group-wise Automatic Mesh-Based analysis of cortIcal Thickness

• 

  Brain development

Cortical thickness overlayed on inflated cortical surfaces

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:

• Voxel-based regional cortical thickness analysis
• Mesh-based local cortical thickness analysis

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

• ARCTIC: Automatic Regional Cortical ThICkness
• GAMBIT: Group-wise Automatic Mesh-Based analysis of cortIcal Thickness

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

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)
