NDI

Established in 1981 and backed by over 40 years of industry expertise, NDI has more than 40,000 systems installed worldwide, supporting applications across neuro, orthopedics, intervention, radiotherapy, endoscopy, dental, ENT, and surgical robotics. At Target3D World, we stock the full NDI range. Polaris, NDI's flagship optical tracking system, uses infrared technology to track markers and reflective spheres with accuracy up to 0.25mm at distances up to 3 metres, making it a gold standard for image-guided procedures, robotic and computer-assisted surgery, and research applications. For tracking inside the body or wherever line-of-sight isn't possible, Aurora and 3D Guidance use a low-intensity electromagnetic field to track miniature sensor coils embedded in instruments like catheters, needles, and scopes, delivering accuracy from 0.5mm to 1mm without disrupting clinical workflow. We also stock NDI's Optotrak and Certus systems, high-precision optical measurement tools trusted across research and biomechanics for demanding motion analysis applications. Whether you're integrating tracking into surgical robotics, building a research-grade motion lab, or developing OEM medical devices, NDI's combined optical and electromagnetic technology gives you accurate, reliable navigation without compromise.
