Interventional MRI procedures, where the surgeon or radiologist is located at the gantry, often require creative communication skills with the technicians in the control room. The problem is that you can’t use conventional headsets because of the magnetic field, which not only interferes with the electronics inside but can also present a danger by sucking the headphones into the tunnel. In addition, the MRI machine itself can be quite noisy. To overcome these problems, Optoacoustics, out of Or-Yehuda, Israel, has developed a nonferromagnetic communication system based on specialized transducers and fiber optic headphones which stay clear of the B-field. So now everyone can wear headsets, and even the patient can listen to music or speak to the surgeon.
