2011 Winter Project Week:UncertaintyVisualization

• 

  Projects List

• 

  Composite image where the marginal distributions of deformed fibertracts and fMRI activated regions are visualized..

• 

  The marginal distributions of a deformed fMRI activated region is visualized.

Objective

We are developing methods for visualizing registration uncertainty.

Approach, Plan

Our approach for summarizing and visualizing registration uncertainty is described in [Risholm 2010].

Our plan for the project week is to incorporate the generation of marginal probability maps as a command line module in Slicer3.

Progress

1. We have a registration framework which produces uncertainty information.
2. A VTK class for generating marginal probability maps of deformed objects.

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a

1. ITK Module
2. Slicer Module
   1. Built-in
   2. Extension -- commandline Yes
   3. Extension -- loadable
