Key Investigators

• Utah: Bo Wang, Marcel Prastawa, and Guido Gerig
• UCLA: Andrei Irimia, Micah Chambers, Jack Van Horn and Paul M. Vespa
• Kitware: Danielle Pace, Stephen Aylward

Objective

• Process more data to test current algorithm
• Segment longitudinal brain MR images with TBI using personalized atlas construction.
• Refine the appearance and atlas construction scheme.

Approach, Plan

Our plan for the project week:

• Get more data from our collaborators to test the current algorithm
• Discuss with collaborators and know more about lesions, tissue compression, necrosis.

Progress

• We got two new subjects from UCLA DBP. We processed the data and tested the current algorithm.
• Talked to our collaborators and learn the knowledge of pathology such as different lesions, necrosis and tissue compression.
• Discussed the possible metrics we could provide to quantitatively analyze the tissue/lesion changes.
