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.

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.
