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 measurement data with sub-millimetre accuracy and precision, over a large measurement volume, without wires. Optical measurement is also known for its 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 the Polaris name has been synonymous with the capabilities—and breakthroughs—achieved in OEM surgical navigation through optical measurement technology. Every advancement of the Polaris product suite makes ever-more complex surgical navigation approaches and systems possible, where today’s technology innovations become tomorrow’s standard of care.
