3D Guidance® Transmitters
Two transmitter sizes are available for a range of OEM tracking applications, from ultrasound probe tracking to guided needle biopsies.
Flexible Integration into OEM Imaging Systems, Trainers, and Carts
3D Guidance® Mid-Range Transmitter
The Mid-Range Transmitter (MRT) offers a flexible setup that can be integrated into OEM applications where the tracking volume needs to cover a larger region. The MRT is a general-purpose transmitter (field generator) and is used in a wide range of OEM system navigation applications in interventional imaging, such as ultrasound probe tracking, ultrasound-guided needle biopsy, and robotic surgery.
The size of the measurement volume is specific to each 3D Guidance sensor, which is determined by the tracking distance achieved on the transmitter’s X, Y, and Z-axes. Larger sensors have a longer tracking distance on each axis, resulting in a larger overall measurement volume.
| Dimensions | 96 x 96 x 96 mm |
| Weight | 2.3 kg |
Maximum Tracking Distance:
Normal Mode: 660 mm (Model 800 Sensor, on positive x-axis)
Extended Volume Mode: 1800 mm (Model 800 Sensor, on positive x-axis)*
| RMS | |
|---|---|
| Accuracy – 6DOF Sensor | |
| Position | 1.40 mm |
| Orientation | 0.50° |
| Translation Range | ± 76 cm in any direction |
| Angular Range | All attitude: ±180 deg azimuth and roll, ±90 deg elevation |
| Update Rate | Up to 765 updates/second |
| Measurement Rate | 80 Hz default; configurable from 20–255 Hz |
3D Guidance® Short-Range Transmitter
The Short-Range Transmitter (SRT) provides a smaller measurement volume for localized tracking in confined, difficult-to-access regions. Its small, lightweight design allows the SRT to be mounted directly on third-party mobile imaging equipment, or inside OEM system surgical simulation phantoms.
| Dimensions | 64 x 46 x 52 mm |
| Weight | 0.29 kg |
Maximum Tracking Distance
410 mm (Model 800 Sensor, on positive x-axis)

| Position | 1.40 mm |
| Orientation | 0.50° |
| Translation Range | ± 45 cm in any direction |
| Angular Range | All attitude: ±180 deg azimuth and roll, ±90 deg elevation |
| Update Rate | Up to 600 updates/second |
| Measurement Rate | 80 Hz default; configurable from 20-255 Hz |
Learn how Electromagnetic Tracking works.
Download our 12-page Education Guide to learn how you can integrate Electromagnetic Tracking Technology into your OEM medical devices to:
- Navigate instruments safely and reliably through complex anatomy.
- Target small treatment areas with
sub-millimeter accuracy and precision. - Visualize real-time position as well as orientation of an instrument.
- Track instruments even when they
are out of sight. - Embed micro sensors into flexible and
rigid instruments.
