12 sub-cortical shapes
Longitudinal Shape Regression - Huntington's Disease
Key Investigators
- Utah: James Fishbaugh, Marcel Prastawa, Guido Gerig
- Iowa: Hans Johnson
Objective
To begin processing longitudinal Huntington's disease data and to apply our shape regression framework to available data. We are interested in the evolution of sub-cortical structures in the brain.
We would like to estimate continuous growth scenarios for several shapes of interest, which can eventually be combined with a framework for 4D registration or 4D atlas construction, to statistically analyze the growth variability within a population.
Approach, Plan
- Segment sub-cortical structures
- Estimate growth trajectories
Progress
Snapshots of the evolution of several sub-cortical structures. Click here for an animation.
