Optical Measurement that Drives Breakthroughs in Surgical Navigation

The Polaris Vega® optical measurement solution has three models of optical trackers that can be integrated into the workflow of OEM surgical navigation systems: the Polaris Vega XT, Polaris Vega VT, and Polaris Vega ST. All three Polaris Vega models share a common optical measurement technology platform, using near-infrared (IR) light to track the real-time positions of OEM surgical instruments via attached navigation markers. Tracking occurs wirelessly over a large measurement volume.

All Polaris Vega models are engineered and built to sub-millimetre measurement accuracy and reliability specifications, delivering trusted tracking performance for the most complex surgical navigation procedures. However, no two tracking applications are exactly alike, which is why each Polaris Vega model has distinct technical specifications and customization options. Add a full library of API commands, and near-countless rigid body and tool design possibilities and every Polaris Vega is as unique as the OEM’s surgical navigation system and application.

Polaris Vega® ST

With a frame rate of 60 Hz, volumetric accuracy to 0.12 mm, and data streaming via Ethernet connectivity, this versatile optical tracker can be integrated into a wide range of surgical navigation solutions.

Polaris Vega® VT

With HD video and IR tracking capabilities providing a live video stream of tracked surgical instruments, this specialized optical tracker can be used in a variety of augmented reality applications.

Polaris Vega® XT

With a volumetric accuracy of up to 0.12 RMS, latency of just 4 milliseconds, and frame rates as high as 250 Hz, our premier optical tracker can be used with a variety of robot-assisted surgical applications.

NDI tracking and measurement products are general metrology components that can be integrated into customer products, research experiments, and/or as components of medical devices that require precision measurement and tracking. While NDI components and technology can be integrated into original equipment manufacturer (OEM) medical devices, they are not specifically intended for a given application and, as such, have not been developed or manufactured in accordance with medical device standards. It remains the responsibility of the OEM customer or end-user to determine and test the suitability of NDI components and technology for their intended use, including performing any required ethics approval, verification, and validation required to demonstrate suitability and compliance. System-level testing, certification, and validation are the responsibility of the original equipment manufacturer or the applicable end-user and should be completed prior to the use of NDI products or technologies in any application.
