Objective

• Combining structural and DTI information for assessment of recovery and treatment efficacy for TBI.
• Coregistration of structural and DTI data of TBI.
• Applying 4D model to DTI data to investigate the changes between acute and chronic time points.

Approach, Plan

• Register DTI to structural images.
• Apply deformation between acute and chronic time points to the co-registered DTI images
• Evaluate initial result with our collaborators

Progress

• using Slicer registration modules to do coregistration between structural and diffusion MRI.
  • talked to James about using Slicer modules to do coregistration, tried his script of using Slicer modules to process TBI data.
  • talked to Martin about coregistration of structural and diffusion MRI in Slicer.
  • tried affine, Bspline, demons registration modules.
• worked with Andrei and Anuja together to solve the problem of loading DICOM images.
• discussed with Andrei and Micah about recent progress and future plan.
• attended the TBI DBP Team Meeting.
