This compact optical tracker provides a smaller measurement volume for targeted tracking of smaller tools within a confined area. Weighing less than a kilogram, the lightweight and portable design of the Polaris Vicra allows it to be mounted almost anywhere. A volumetric accuracy of 0.25 mm RMS and 95% confidence interval of 0.5 mm ensure the most subtle tool movements are precisely tracked and localized.

Our standard optical tracker delivers exceptional measurement accuracy and reliability – hallmarks of our entire Polaris line. Volumetric accuracy to 0.12 mm RMS is achieved over a large measurement volume, with tracking data streamed via Ethernet. An optional Extended Pyramid Volume and Positioning Laser augment flexibility and control.

This industry-first optical tracker combines HD video and IR tracking to capture a live or recorded view of tracked tools within the measurement volume. Video data and IR tracking data are aligned in real time to a common frame of reference. Different camera resolutions and settings maximize the capture of high-contrast images.

Our most advanced optical tracker delivers volumetric accuracy to 0.12 mm RMS with minimal noise, latency of just 6 milliseconds, and a frame rate as high as 250 Hz, for measurement data that is capable of real-time integration into robot-assisted surgery systems. Tight data synchronization and Ethernet connectivity add to best-in-class measurement performance.

Principle use case of our technology: Today, doctors expect systems that support them and minimize risks to the patient. Previously, a frequent challenge was combining navigation and operation. You can see the principle behind our navigation technologies here with the example of our Aurora® electromagnetic measurement system.
