NDI Navigation Markers – Detect OEM Instruments with Pinpoint Accuracy
Navigation markers are a key component of the Polaris® optical navigation solution. When attached to OEM instruments, navigation markers function as triangulation points for the instrument within the treatment space. This is due to the marker’s unique retro-reflective surface, which allows the Polaris optical tracker to ‘see’ it during tracking. The navigation marker and the Polaris optical tracker work together to localize, detect, and track OEM instruments with pinpoint accuracy.
NDI’s passive markers include the NDI Passive Sphere™ (for snap-fit posts), the Disposable Reflective Marker Sphere (for Brainlab threaded posts), and the Radix™ Lens.
Snap-Fit Sphere
The NDI Passive Sphere is a single-use, sterile 11.8 mm passive marker sphere compatible with instruments with snap-fit mounting posts.
Radix Lens
A wipeable, retro-reflective lens for use with optical navigation
applications. The smooth plastic surface makes it highly impervious to liquid and particulate contamination.
Threaded Sphere
(Brainlab® Systems Only)
A single-use, sterile 13 mm passive marker sphere for use with Brainlab image-guided surgery systems and instruments with threaded posts.
Active Markers
The Polaris optical tracker detects the infrared light emitted by the active markers and calculates the position and orientation of tools that incorporate them.
