miniBIRD® 500 & 800






miniBIRD offers full functionality of our other DC magnetic trackers, with miniaturized sensors as small as 5mm wide. The miniBIRD 800 is also available as an ISA-based configuration that supports simultaneous tracking of two 8mm sensors.


  • 3D image rendering in ultrasound
  • Measurement of anatomical structure and function
  • Laproscope, endoscope, and surgical instrument tracking and placement
  • Intrabody navigation, localization and guidance
  • Real-time simulation and visualization
  • Monitoring of human and animal motion for biomechanical analysis


Miniaturized Sensors
  • Excellent for internal measurements.
Pulsed DC magnetic technology
  • Minimal sensitivity to metal. (Medical grade stainless steel does not affect tracker).

  • Five times less susceptible to distortion caused by nearby metal than AC technology.
6 degrees-of-freedom
  • Unrestricted range of motion.
1-4 sensors with dedicated processors
  • Simultaneous tracking of multiple sensors with highest measurement rates.
Proven technology
  • Seamless integration.
