Helping you build the future

Accurate Object Tracking for Advanced Surgical Procedures

Radwave® is a modular, customizable electromagnetic tracking platform that reliably delivers high performance and accuracy for biomedical & other applications. Discover how Radwave® overcomes the obstacles of electromagnetic tracking technology offered elsewhere, including limited sensing volume & EM interference.


While legacy options have fixed, limited sensing volumes, our patent-pending modular design enables large, flexible configuration that can be tailored to your needs.

Accurate & Reliable

Detect metal & electromagnetic interference in ways that no other tracking system can, using proprietary algorithms and components to maintain accuracy.

Fast & Cost-Effective

Building a custom tracking system from scratch can take years, with costs adding up. Radwave® electromagnetic tracking system is ready out of the box and offers quick and cost-effective integration with your device.

Strong Experienced Team

Our team of industry leaders with over 100 years of combined experience knows how to design, develop, and deploy an electromagnetic tracking technology for your medical device.

Integration-ready Components

We work directly with you to equip your device with custom electromagnetic tracking hardware and sensors, tailored to your needs.
