01 Sensor fusion, visual and active interfaces for minimally invasive surgery

		Optical tracker "Easy Track200" integrated into a surgical microscope to perform navigation during microscope based surgery. Developed within NCCR Co-Me, produced by spin-off Atracsys LLC.

To allow surgeons to benefit from pre- and intra-operative data during minimally invasive surgery, we are developing: 3D model construction/update, physics-based graphics, human-oriented computer vision, optical tracking and large-workspace haptics. We use these techniques to build active user interfaces for biopsy, stent placement, hip replacement, and surgeon-computer interaction.

The underlying technology integrates several disciplines, among these mechatronics and micro-engineering.

Abdominal aortic aneurysm implant planning

Visualization system to improve the choice and placement of prostheses.

Haptics - Biopsy Navigator

Surgical navigation system to improve needle insertion.

Orthopedics - Hip surgery tools

Orthopaedic positioning system for total hip replacement.

Low-cost optical tracking

Compact, low-cost, optical tracking system for real-time, 3D position measurement. (=Easy Track200))

Real-time soft tissue modeling

Development methods for automatic model update and shadow rendering.

Surgeon-computer interaction

System development to operate computers using hand-gestures.
