Helping you build the future

Custom electromagnetic tracking for medical devices & more

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


While legacy options have fixed, limited sensing volumes, Radwave’s 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 tracking system from scratch can take years, with costs adding up. Our electromagnetic tracking system is ready out of the box and offers quick + 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.

Field Generator / Antenna

The antenna generates a low-intensity electromagnetic field that establishes the sensing volume. Multiple types (and corresponding sensing volume sizes) available.
RWAP1-01 Standard
Thin, light antenna with large sensing volume for placement between the patient and the bed, below the bed, or integrated with the bed.
RWAP2-01 Open Air
Designed for procedures requiring intraoperative fluoroscopy & CT scan, this antenna design creates the needed sensing volume without compromising visibility. Available in 2021.

Additional field generator types & dimensions will be available in 2021.


Small 5 & 6 DOF sensors ready to integrate into your tools and instruments.

Currently available sensors:

RWS5.1 – 5 DOF sensor (0.40mm x 3.90mm)
RWS6.1 – 6 DOF sensor (1.25mm x 3.00mm)

Reference sensors & additional sensors will be available in 2021

Control Unit


Provides sensor & antenna connections, calculates positions & orientations of each sensor, and interfaces with the host computer. Track multiple sensors and tools simultaneously with flexible port configurations and high sampling rates (up to 500Hz) to keep up with the high demand.

  • 1U rack mountable unit (4.5cm high x 33.0cm long x 40.6cm wide)
  • 5 x three-coil sensor port connectors
  • 1 x nine-coil sensor port connector
  • A/C power
  • Sampling Rate from 30 to 500 Hz
  • Ethernet interface with modern TCP/IP connection

Our software is designed for easy setup and rapid application development.

Application Programming Interface (API)

  • Used for communication between the application and the Control Unit
  • Available in C++ or C
  • Available for Windows 10 or Linux

Demonstration Application (Demo App)

  • Uses the API to communicate with the Control Unit
  • Displays system status and version
  • Updates the Control Unit software
  • Displays the Antenna and sensors tracking information
  • Source code files are provided to accelerate development and integration
