2011 Winter Project Week:UncertaintyVisualization

• 

  Projects List

• 

  Scatter plot of the original FA data through the genu of the corpus callosum of a normal brain.

• 

  Regression of FA data; solid line represents the mean and dotted lines the standard deviation.

Key Investigators

• SPL: Petter Risholm, William Wells

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

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