Why Choose Optical Measurement?

Optical measurement (optical tracking) has long been an important component of OEM surgical navigation systems, where it can provide measurement data for real-time surgical tool tracking. The Polaris optical trackers deliver reliable measurement data with sub-millimetre accuracy and precision over a large measurement volume. NDI’s wireless Polaris® has established itself for robust and reliable tracking performance in almost any environment.

When integrated into the workflow of surgical navigation systems, the Polaris optical tracker acts as the link between patient image sets and the physical 3D space. It enables the positions and orientations of surgical tools to be instantly localized and visualized within the operative field. Multiple tools can be tracked at once without interrupting the surgical workflow.

For more than 20 years NDI’s Polaris has been considered synonymous with the capabilities and breakthroughs it has achieved in OEM surgical navigation through its optical measurement technology. Every advancement of NDI’s Polaris product suite makes increasingly complex surgical navigation approaches and systems possible. Today’s technological innovations become tomorrow’s standard of care.

Polaris Vega XT

Principles of Operation

The Polaris Vega® and Polaris Vicra® optical measurement solutions work by using near-infrared (IR) light to wirelessly detect and track navigation markers attached to OEM surgical instruments. They do so over a large measurement volume, and with exceptional tracking accuracy and precision. Optical measurement technology is also known—and trusted—for its reliable tracking performance in almost any clinical environment.

Every advancement of the Polaris® product suite represents new opportunities for medical device OEMs to innovate ever-more-complex surgical navigation systems and approaches. Where today’s technology breakthroughs become tomorrow’s standard of care. It’s why the Polaris solutions have been integrated into the workflows of OEM surgical navigation systems for more than 20 years.

1. Markers can be attached to OEM surgical instruments.

2. The Polaris optical tracker floods the measurement volume with infrared (IR) light.

3. This light is reflected from the markers back to IR sensors on the Polaris optical tracker.

4. The points where the light intersects are used to triangulate the markers’ 3D (X-Y-Z) coordinates within the measurement volume.

5. Coordinate data are mapped to the associated instrument and used to calculate the transformations (poses) of the instrument.

6. Tracking data are communicated to the host application for real-time visualization & navigation of instruments relative to patient image sets.
