April 2017

Following dozens of iMRI research installations, Optoacoustics' will bring a fully scalable version of its wireless IMROC-IR™ Communications System to clinical MRI practitioners at the 25th Annual ISMRM Meeting in Honolulu next week.

The IMROC system's multi-channel noise canceling features enables doctors, staff and patients to converse freely during MRI scans as an essential component of interventional MRI suites. With its wireless IMROC-IR in 2011, Optoacoustics pioneered complete 'walk-and-talk' communications flexibility to as many as 8 participants in the most advanced MRI environments.

"For years, working together productively in MRI was stilted by the unbearable noise," explains Dr. Yuvi Kahana, CEO of Optoacoustics. "Our multi-channel headsets got everyone talking again – no more yelling or hand signals. It works great and we've now scaled the System down to make it possible for smaller hospitals and clinics to add the IMROC to their MRI facilities."


With patient comfort an increasingly critical requirement for successful MRI scans, the IMROC-IR provides not only a quieter and calmer experience, but also the ability to casually converse with others from inside the bore. And its multi-channel capability enables fully selectable dialogs between anyone in the MRI suite.

"Even the youngest patients can stay in constant contact with their parents during the scan," Kahana adds. "We're very excited about the potential for introducing our wireless headsets to facilities of all sizes."

Like Optoacoustics' other MRI communications systems, IMROC is considered the gold standard both for its high sound quality and day-to-day working robustness. IMROC is US FDA 510(k) cleared.
