2010 Summer Project Week Quantification Of Lesion Diffusion Disruption

• 

  Projects List

• 

  Tracts interrupted by lesions with FA values.

Key Investigators

• ABMIG: H. J. Bockholt
• MRN: Mark Scully

Objective

Quantify the effect lesions have on diffusion.

Approach, Plan

Our initial approach for quantifying diffusion interruption is to compile statistics on the distributions of FA at varying distances from lesion tissue. Assuming there are significant differences more advanced methods, such as using graph laplacians to estimate probable tracts will be investigated.

Progress

Using diffusion tools in slicer FA images were created in the same space as the lesion images. ITK code for summarizing statistics is almost complete.

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a Slicer3 commandline extension.
