Home < 2012 Winter Project Week: Continuous 4D shapes
Snapshot of sub-cortical shape evolution. Color denotes magnitude of velocity.
Key Investigators
James Fishbaugh, Hans Johnson, Guido Gerig
Objective
During the 2011 summer project week, we applied our shape regression framework to sub-cortical shapes from a single HD subject. For this project, we plan to begin processing multiple subjects. We would like to compare the trajectories of various measurements of interest, such as volume, across subjects at different stages of disease progression.
Approach, Plan
- Estimate continuous trajectories for sub-cortical structures for multiple subjects
- Investigate volume changes between subjects at different stages of disease progression
- Explore shape evolution for other potentially significant measurements
