The Polaris Vicra® shares the same trusted measurement performance as all Polaris optical trackers, but in a smaller form factor. Its compact size can allow medical device OEMs to integrate the Polaris Vicra into surgical workflows that require smaller instruments and where equipment or operative space is limited. Exceptional Measurement Accuracy The Polaris Vicra tracks 3D tool positions with sub-millimetre measurement accuracy and repeatability. The most subtle OEM surgical tool movements are precisely tracked and localized in real-time, with volumetric accuracy to 0.25 mm and 95% confidence interval of 0.5 mm. Compact Hardware Design The Polaris Vicra features a compact form factor and weighs just 0.8 kg. It can be mounted or transported almost anywhere – even in areas where equipment or operative space is tight. Its portable design is enhanced with a pre-calibrated measurement volume and quick system start-up. Optimized Measurement Volume The Polaris Vicra has a smaller measurement volume that is optimized for targeted tool tracking within localized areas. Polaris Vicra tool geometries are correspondingly reduced, which allows for lighter and more ergonomic OEM instruments that allow very precise movements. Customizable System Implementation The Polaris Vicra comes with different software utilities to customize how the optical tracker and tools interface with the OEM host application. Tool geometries and other tracking parameters are set by a tool definition file, while a built-in API speeds application development and integration.
