Software for the fiber tracking and statistical analysis along the tracts has been implemented. The statistical methods for diffusion tensors are implemented as ITK code as part of the [[NA-MIC/Projects/Diffusion_Image_Analysis/DTI_Software_and_Algorithm_Infrastructure|DTI Software Infrastructure]] project. The methods have been validated on a repeated scan of a healthy individual. This work has been published as a conference paper (MICCAI 2005) and a journal version (MEDIA 2006). Our recent IPMI 2007 paper includes a nonparametric regression method for analyzing data along a fiber tract.

Objective

We are developing a hybrid neuronavigation system which combines a Brainlab navigation system with optical tracking, an Aurora electromagnetic (EM) tracking device and 3D Slicer to enhance current neurosurgical practice. We will add micro EM sensors to neurosurgical tools in order to track their tip location and integrate position and orientation into a 3D Slicer navigation environment.

Approach, Plan

Our approach is to use Brainlab to perform patient to image registration and patient tracking, and to use the Aurora device to track the tip location of the tools. OpenIGTLink will be used to interface patient images and tracking data into 3D Slicer<foo>.

Progress

This work has been granted funding by CIMIT and is scheduled to be completed in 2010. Talked to Brainlab to set up a lab based hybrid optical EM tracking system to experiments. Started Slicer3 module for navigation. Got information from Georgetown and Johns Hopkins on tips to using the Aurora tracking device and assuring accurate tracking.
