Project Description
Objective
- Develop a system to use calibrated, tracked ultrasound (US) 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: US image and probe tracking information (PLUS system).
- Code development: pre-op to intra-op image matching using local image features.
Progress
Developed and tested code for:
- Input of PLUS US data
- Computation of local feature correspondences between different US sweeps
Result
Example result: Correspondences computed between different US sweeps, PLUS kidney data
