Visualization of Wrist Bones and Ligaments

We work on visualizing diffusion tensor MRI(DTI) data sets. We extract the diffusion information from the diffusion tensor fields by constructing goemtric models that match different types of diffusions. The models are displayed on various graphics environment, including the Cave and the fishtank VR system. The doctors are using our system to discover features and patterns in DTI data sets.

Project status: Active
