Abstract
A technique for reducing acoustic noise emitted by a magnetic resonance imaging system includes providing energy dampening elements in the scanner, such as within the gradient coil assembly, between the gradient coil assembly and the primary magnet, and around the outer and inner peripheries of the primary magnet and RF coil. The elements may be formed to conform to the structures of the scanner, and may be tile-like elements which can be fitted to new scanners and retrofitted to existing equipment.
