  • MGH: Greg Sharp

Objective

We are tuning and testing multimodal image registration in plastimatch to allow accurate localization of the trigeminal nerve. The final objective is to register an atlas to patient CT, in order to avoid 3T MRI. The registration would allow the physician to identify the trigeminal nerve on the atlas and plan the Cyberknife treatment accordingly.


Approach, Plan

Our approach is to crop and "threshold" the CT and to crop the atlas to obtain a more robust result. The output of Bspline deformable registration is than compared to the patient 3T MRI (whenever possible in the same modality - T1). The MRIs are acquired generally with CISS sequence.

Our plan for the project week is:

  • solve issues with parameter handling between rigid and non-rigid stage
  • investigate why the cropping is necessary for the registration to produce an output "acceptable" (TO BE DEFINED)
  • investigate the thresholding
