Neurosurgery Surgical Navigation System

Compact Size with Exceptional Measurement Accuracy and Reliabilityinput:
output:The Polaris Lyra, NDI's compact optical tracker, is the optimal solution for applications that concentrate on a single body segment due to its small footprint, short stand-off, and expansive measurement volume. The Polaris® suite of products is characterized by a high measurement rate, high accuracy, and low data latency, which contribute to their trusted reliability.Exceptional Performance and Accuracyinput:
output:Sub-millimeter measurement accuracy and repeatability are achieved by the Polaris Lyra in tracking 6D tool positions. The movements of OEM surgical tools are precisely tracked and localized, with a measurement rate of up to 125 Hz.input:
output:Measurement Volume Optimizationinput:
output:The measurement volume is designed to facilitate the tracking of specific tools within localized regions. The geometries of Polaris Lyra tools are correspondingly reduced, enabling the development of OEM instruments that are more ergonomic and lightweight, and that support extremely precise movements.input:
output:Hardware Design with a Compact Sizeinput:
output:Polaris Lyra is characterized by its compact design and a weight of less than 1.0 kg. The camera can be mounted in close proximity to the application area due to the short stand-off. Its performance is improved by a pre-calibrated measurement volume and a rapid system start-up, which further enhances its portable design.input:
