Compact optical tracking units for confined clinical spaces
Small-footprint optical tracking units designed for instrument tracking inside confined clinical and surgical suites, providing high positional and orientation accuracy and a measurement volume suitable for OEM integration.
Optical marker assemblies (active and passive)
Marker systems in active and passive implementations, including disposable reflective markers and lens-based markers for optical localization of instruments and patient anatomy.
Electromagnetic tracking subsystems for OEM integration
EM tracking subsystems that include electronics units, field generators, and pre-characterized micro-sensors to enable real-time instrument tracking without line of sight.
Desktop and embedded tracking electronics (standalone and drive-bay)
Electronics units available as standalone desktop units or as embedded modules that compute position/orientation matrices and expose data to host applications; units support multiple simultaneous 6DOF sensors and configurable measurement rates.
Pre-assembled, pre-characterized electromagnetic micro-sensors
Small coil-based sensors supplied fully assembled, wired with connectors, and delivered with characterization data, intended for embedding into flexible and rigid instruments including needle tips, catheters, scopes, and guidewires.
Tool definition and calibration software
Software packages to configure, define, and characterize developer kits and tracking tools, producing tool transforms and integration-ready configuration for host applications.
