Electronics unit with 8 mm
sensors and transmitter.

COMPONENTS

• Electronics unit

• DC magnetic field transmitter

• 8 mm and 5 mm sensors

• Power supply

TRANSMITTER OPTIONS

Mid-Range
Transmitter

Up to ±76.2 cm in any direction
Coverage Set-Up & Use: Our mid-range transmitter is ideal for desktop applications in environments containing conductive metals.

APPLICATIONS

  • 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

FEATURES AND BENEFITS

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.
