• Develop a system to use calibrated, tracked ultrasound to intra-operatively track and visualize pre-operatively defined neurosurgical targets.
• Challenges: 2D-3D registration, intra-operative deformation and missing tissue, inter-modal image registration.

Approach, Plan

• Data preparation: ultrasound image and probe tracking information (PLUS system).
• Code development: pre-op to intra-op image matching using scale-invariant features.
