Polaris Vega® XT

Industry-leading performance and reliability for OEM surgical tool tracking and navigation applications.

NDI’s Premier Optical Tracker for OEM Robotic Surgery Systems

The Polaris Vega® XT combines unrivalled measurement accuracy, high-speed tracking, and low latency facilitating easy integration of 3D tracking within surgeon-controlled workflows, autonomous OEM robotic surgery systems, and applications.

When used as a component of an OEM robotic-assisted surgical system, the Polaris Vega XT can track the positions of the robot base and end-effector in 3D space via attached navigation markers. Markers can also be attached to handheld OEM surgical instruments. The Polaris Vega XT can track the robot, surgical instruments, and patients in real time relative to each other within the same coordinate system, during the same procedure. The positions and orientations of each tracked object(s) are uniquely identified by their distinct marker configurations, and instantly localized and visualized within the OEM host interface.

Polaris Vega XT

Unrivaled Measurement Rate

The Polaris Vega XT has an improved maximum frame rate of 400 Hz and reduced latency below three milliseconds, which allows for fast and efficient transfer of tracking data within robot-control systems. The frame rate remains constant even when multiple tracked tools are in view.

Enhanced Communication Protocol

The Polaris Vega XT optical tracker now supports both TCP and UDP network communication methods. Selectable through the API, the addition of UDP provides users with a better option for wireless host communications in time-sensitive applications.

Exceptional Measurement Accuracy

The Polaris Vega XT delivers volumetric accuracy to 0.12 mm RMS with minimal noise. Track tools with total confidence; hardware characterization, and factory calibration optimizes accuracy for measurements that are highly repeatable and reliable.

Ease and Speed of Integration

The Polaris Vega XT includes software, source code, and API tools to streamline the design and development of tools, and to speed integration with OEM software applications. The software suite also includes utilities to support ongoing system diagnostics and maintenance.
