Electromagnetic/optical surgical navigation device tracking system

Surgical navigation systems are intraoperative real-time devices that enable navigated surgery by using CT-based three-dimensional planned references with identified anatomical landmarks to guide the intraoperative positioning of tools and implants relative to rigid anatomical structures. These image-guided planning and navigation systems enable navigated surgery in cranial and other anatomical regions , with applications including support for achieving pre-defined screw positioning during spinal and trauma surgical procedures.
