Our Versatile Optical Tracker for Diverse OEM Surgical Applications

The Polaris Vega® ST is a versatile optical tracker that can provide trusted measurements in an array of OEM-supported surgical applications, delivering accurate and reliable 3D tracking data. Tracking is achieved via navigation markers attached to OEM surgical instruments such as probes, shavers, awls, drills, microdebriders, and more.

Exclusive to the Polaris Vega ST is an available Radiation Hardening option. The Radiation Hardening option protects the optical tracker from gamma and neutron radiation through a shielded processor and modified memory management. This extra protection allows the Polaris Vega ST to be safely integrated into OEM surgical navigation systems and workflows used in radiation therapy suites.

More customization options are available to enhance system utility and flexibility. The Positioning Laser assists with positioning the optical tracker and/or surgical equipment within the measurement volume. The Extended Pyramid Volume nearly doubles the measurement volume, which benefits procedures requiring a clear view of several surgical instruments simultaneously.

Exceptional Measurement Accuracy

The Polaris Vega ST delivers high volumetric accuracy to 0.12 mm RMS with low noise. Track passive spheres attached to tools with confidence; hardware characterization and factory calibration optimize accuracy for measurements that are highly repeatable and reliable.
