NDI PolarisVega -Model ST -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 that can be 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 by way of 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 that are 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 that require a clear view of several surgical instruments at once.
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.
- Volumetric Accuracy1,2 RMS : Pyramid Volume: 0.12 mm Extended Pyramid: 0.15 mm
- 95% Confidence Interval1,2 : Pyramid Volume: 0.20 mm Extended Pyramid: 0.30 mm
The Polaris Vega ST has a built-in API and available software to facilitate tool development and accelerate integration into OEM and end-user software applications. The NDI ToolBox software includes utilities for ongoing system diagnostics and maintenance.
- Tool Types : Passive, Active Wireless
- Maximum Number of Tools : Load up to 25 tools (maximum of 6 active wireless)
- Maximum Number of Markers per Tool : 6 single-face/20 multi-face
The Polaris Vega ST can include optional radiation hardening to maintain accurate and reliable performance in harsh environments, such as those found in radiation therapy suites. Consistent operation in variable room conditions add to product robustness.
- Measurement Rates : 20, 30, 60 Hz
- Average Latency : < 16 ms (typical) at 60Hz
- Measurement Volumes : Pyramid, Extended Pyramid (optional)
The Polaris Vega ST comes with Gigabit Ethernet capable of streaming high-speed tracking data back to the OEM host application. The Ethernet connection also provides power to the Vega and allows for greater flexibility and interoperability of equipment within the operative space
- Data Communication : Gigabit Ethernet
- Maximum Number of Tools : Network Synchronization
- Data/Power Interface : Ethernet, RJ45
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.
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.
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.
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.
