2012 Winter Project Week:TBIValidation

• 

  Projects List

• Visualization of the deformation between acute and chronic images
• 

  Visualization of the deformation field via determinant of Jacobian

• 

  Visualization of the deformation field via vector magnitude

Key Investigators

• Utah: Bo Wang, Marcel Prastawa, and Guido Gerig
• UCLA: Andrei Irimia, Micah Chambers, Jack Van Horn and Paul M. Vespa
• Kitware: Danielle Pace, Stephen Aylward

Objective

• Defining manual segmentation protocol for MR images of TBI
• Comparing the independent segmentation and joint segmentation using Dice test
• Visualizing volume changes, deformation field

Approach, Plan

Our plan for the project week:

• Working with collaborators to define manual segmentation protocol
• Visualizing volume changes and deformation field according to clinicians' requirements.

Progress

To be added.

Delivery Mechanism

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