Objective: We want to add various statistical measures into our PDE flows for medical imaging. This will allow the incorporation of global image information into the locally defined PDE frameowrk.

Progress: We developped flows which can separate the distributions inside and outside the evolving contour, and we have also been including shape information in the flows.

Completed:

• A statistically based flow for image segmentation, using Fast Marching

Code

• The code has been integrated into the Slicer
• A user-oriented tutorial for the Fast Marching algorithm is available at:Slicer Module Tutorial
