The ZMBBI equipment description includes specifications about the MR systems, available coils, RF shop and instrumentation shop resources, spaces, and staff available to MR Center users.

Researchers have the option of two different systems for audio stimulus and 2-way communication: the Optoacoustics OptoActive II audio system, and the Avotec Silent Scan 3300 system.

The Optoacoustics OptoActive II system

This is an active noise cancellation headphone system for MRI use. The system uses real-time algorithmic, active harmonic noise cancelling, as well as Optoacoustics’ proprietary passive noise reduction techniques, to reduce 95 percent of MR EPI main gradient resonance for the patient.

OptoAcoustic headphones

The headphones are slim and fit most participants' heads inside the headcoil.

OptoActive Noise-Canceling Headphones in headcoil

Participant responses can be heard and recorded by using the OptoAcoustic FOMRI-III™ Microphone. This can be mounted securely on the head coil.


Additional information, including FAQs, can be found in the OptoAcoustics OptoActive II audio system brochure.



Avotec Silent Scan 3300

This is a fully- calibrated MRI audio delivery and two-way communication system.

The Avotec system is appropriate when headphones won't fit in the headcoil, and an earbud/ earplug audio system is needed.
