Polaris Series

The Polaris® optical tracking solution gives medical simulator manufacturers exceptionally accurate and reliable 3D tracking of simulated medical tools (via attached markers) over a large measurement volume. The Polaris emits infrared light to wirelessly detect and track a tool’s position and orientation in all six degrees of freedom. Trusted by surgeons worldwide for performing computer-assisted surgery and therapy, the Polaris represents the ideal technology for replicating those same procedures in an interactive, virtual environment for surgical training and surgical rehearsal.

The position and orientation of each medical tool is tracked and displayed within the simulation software in real time. Data integration occurs seamlessly and instantly, providing uninterrupted tool interaction. The Polaris enables a closed-loop system for real-time haptic feedback of tool use, allowing for quantifiable evaluation of the trainee’s surgical technique and performance. When combined with actual CT or MRI scans of patients, the result is a surgical simulation system that provides a training experience that’s highly accurate and true to life.

System Components


The flexible Polaris solution is comprised of different hardware components that can be configured for different medical simulator form factors and integration specifications. The large measurement volume provided by the Polaris Spectra® is especially beneficial for larger, fixed medical simulation systems, including the surgical theatre itself.

  • Polaris Spectra®: for simulation environments that require a large measurement volume.

  • Polaris Vicra®: for simulation environments that require a small, targeted measurement volume.

  • Host USB Converter: acts as a communication link and power source for the Polaris Spectra or Vicra and the host computer.

  • System Control unit (SCU): provides the interface between the Polaris, tools (markers), and host computer.
