Objective

  • To explore the portability of Optimal Mass Transport (OMT) Non-rigid Registration code to the NAMIC toolkit.
  • To determine applicability of OMT registration algorithm for DWI Distortion Correction.

Approach, Plan

Progress

  • Currently the algorithm and registration framework is available in MATLAB
  • Preliminary results with DWI baseline image correction.
  • DWI and MRI image intensity normalization using CSF and White-Matter/Grey-Matter segmentations performed to make sure both image volumes are on same footing so that Mass Transport mapping is found without introducing structural distortions.
  • Further experiments required to fine tune the normalization step.
  • Slicer command line module created for interfacing with OMT Registration algorithm. A few issues with nrrd files being resolved.
  • Discussions with Core 2 on existing infrastructure within ITK for non-rigid registration and re-use of demons diffeomorphic registration filter framework for OMT Registration filter.
