Optical Navigation Technology

The Polaris family of optical trackers is used to track the position and orientation of surgical instruments in 3D space in real-time. These trackers use infrared light to detect reflective markers attached to the instruments and triangulate their positions. The tracking data is then processed by a host application, which displays the instruments’ locations and paths like how a GPS tracks a device’s location.

Electromagnetic Tracking Solutions

NDI’s Aurora® Electromagnetic tracking technology uses an electromagnetic field to accurately localize and track OEM medical instruments in 3D space. It provides real-time tracking of microsensors that can be embedded into rigid and flexible OEM medical instruments such as ultrasound probes, endoscopes, catheters, guidewires or even at the tip of a needle. 

How Passive Marker Spheres Work

NDI pioneered the development of the passive marker sphere, which is attached to surgical instruments and acts as a location point in the OR. NDI Passive Spheres are used to calibrate the NDI Polaris tracker and optimize measurement performance.
