Best-In-Class Tracking Platform & Sensor Technology

EM Tracking Platform
by

Designed from the ground up using advanced technologies and modern components to deliver high-performance object tracking.

Top Features:

  • Seamless integration into MIS and robotic procedure
  • Accurate and reliable with high sampling rates
  • Able to track many different sizes and types of sensors
  • Translucent antenna during fluoroscopy with uncompromised image quality
  • Customisable sensing volume that can grow or shrink to match the procedure’s needs
  • Rapid integration using encrypted, modern API with open-source SDK

Radwave™ Electromagnetic Tracking platform provides exceptional accuracy, reliability, and performance needed for advanced robotics and minimally-invasive surgical (MIS) procedures.

Sensor Platform 
by 
TT’s sensor technologies deliver the highest degree of accuracy and precision, even in challenging settings where other EM systems have been limited by interference or sensing volume constraints. We have sensors in both 5 degrees of freedom and 6 degrees of freedom configurations. TT’s sensor technologies are easily integrated into a variety of interventional and minimally invasive devices.

TT Electronics is ISO 13485 certified and offers FDA registered and clean room manufacturing facilities. Our clean room facilities are flexible and expandable. They can be configured to meet the specific needs of each unique project with maximum efficiency.

TT Electronics’ sensor technologies deliver the highest degree of accuracy and precision.
