Optical Microphone for MRI - The voice of the patient
Optoacoustics optical microphone answers the challenge of communication during
an MR procedure, delivering patient comfort and safety. MRI exams typically
range in length from 20 minutes to 2 hours, requiring patients to remain still
for extended periods of time. Any movement during the scan can cause distorted
images, only creating even longer scan times, as they will have to be repeated.
Furthermore, the noise levels generated by scanners range anywhere from 110
- 130dB. This creates an uncomfortable environment and broadens the gap between
the patient and the outside.

SAFETY
Currently, there is no effective direct communication between the patient and
the staff. The alternatives to speech, are panic alarm buttons or the patient's
signaling to alert the control room technician of a problem. These alternatives
do not identify or define the situation.
Optoacoustics optical solutions enable speech so the patient and technician are
connected and in contact at all times.
Naturally, due to the enormous magnetic field, MRI labs cannot tolerate metal
objects as found in standard microphones. Optoacoustics optical solutions are
entirely passive, so multiple microphones can be used effectively inside the
lab.
The optical microphone can work as a stand-alone, independent solution enabling
the patient to communicate to the staff or compliment a current simplex communication
system.

HOW IT WORKS:
The revolutionary optical microphone records sound by sensing changes in light.
The Optical microphone head does not contain any metal and is connected to
the electronic system via fiber optic cable. Therefore, the optical microphone
is absolutely safe for MRI environment.
