Abstract
An RF coil assembly for use in a Magnetic Resonance Imaging scanner incorporates sound absorbing material in its construction for the purpose of attenuating the sound perceived by a patient lying inside the RF coil. Unlike a conventional RF coil assembly in which rigid components are used to support the coil within the magnet bore, the quiet RF coil assembly is constructed without rigid support components. In one embodiment, open cell foam may be used to support the RF coil components and the entire assembly is wrapped in a. flexible cloth-like material.
