OMT Deformation Grid on MRI

OMT Deformation Grid on DWI

Key Investigators

• Allen Tannenbaum, Tauseef ur Rehman, Ivan Kolesov(Georgia Tech)
• Marek Kubicki, Sylvain Bouix (BWH)

Objective

To determine applicability of OMT registration algorithm for DWI Distortion Correction.

Approach, Plan

• Work with Core 3 to obtain an accurate white matter segmentation from both DWI and MRI datasets
• Investigate different methods for normalizing intensity profiles for MRI and DWI images to setup the problem for mass transport based registration
• Work with Core 3 to compare results with other approaches
• Apply the localized intensity normalization approach to 3D datasets

Progress

• Currently the algorithm and registration framework is available in MATLAB
• Localized intensity normalization using windowing approach developed and tested in 2D
