Guardian™ G1 Wireless Audio System • No long pneumatic tubes to manage for improved workflow • MR Conditional wireless audio system for use with high feld MRI up to 3.0T • Integrates audio entertainment, the technologist’s voice, and AutoVoice for optimum patient communication • Dramatically attenuates gradient noise and hearing protection tested according to ANSI S3.19-1974 • Standard 3.5mm audio jack allows patients to listen to music from most audio devices • FDA cleared Studies show1 that even with standard ear protection, MRI can damage hearing ability or cause tinnitus for weeks after an exam. Sometimes, the damage is permanent. Meet Guardian™ G1: redefining the standard in hearing protection and patient comfort for MRI. Excessive gradient noise during an MRI examination can cause discomfort, stress, and over time, may lead to hearing damage. The noise reduction rating (NRR), a unit of measurement used to determine the effectiveness of hearing protection, is an important consideration when selecting an MR audio system. The Guadian™ Wireless Audio System has an NRR of 29 decibels (dB), allowing its use without additional earplugs at noise levels up to 128 dB. To facilitate its use in studies utilizing a head coil that cannot accommodate an over-the-ear headset, the Guardian™ Wireless Audio System includes a wireless earbud solution also rated at 29 dB NRR. Prior to the introduction of the Guardian™ Wireless Audio System, most other MR audio systems have employed 1960s pneumatic tube technology. Wireless, tubeless technology is more comfortable than pneumatic tube systems and eliminates the possibility of the headphone displacement when the table advances. The speakers reside inside the headphones near the ear to provide the highest quality sound.

The Guardian™ G1 Wireless Audio System installs directly to the existing technologist console making for a clean installation and allowing for both audio entertainment as well as technologist communication. Technologist push-to-talk voice and AutoVoice commands automatically interrupt the music for clear communication to the patient.
