Persaio® Overview


This product is out of stock.

Persaio® is an active noise cancellation system for use in MRI research studies*. The system eliminates the need for the creation of special scan sequences in order to obtain vocal response data by seamlessly integrating with standard scans. Employing a single MR-compatible microphone and the Repetition Time (TR) Persaio utilizes patent-pending technology to reduce scanner noise dramatically (up to 30 dB in real-time) allowing researchers to hear their participants' speech clearly. The unaltered audio and the noise-cancelled audio can be played or recorded. Persaio works with electrical and optical TR pulses. Persaio is designed with an integrated, high-quality optical microphone. However, it can be used with pre-existing MR patient microphones.

*Optimized for EPI scan sequences!
