Patent ID: 6998949

Claim:
A magnetic resonance imaging (MRI) system comprising an examination volume, a main magnet system for generating a magnetic field in the examination volume, and a gradient magnet system for generating altering gradients of the magnetic field in the examination volume, the gradient magnet system being accommodated in at least one housing having a main wall facing the examination volume and a substantially conical wall facing away from the examination volume, said main wall and said conical wall enclosing a substantially angular tip portion of the housing, characterized in that the MRI system comprises a plurality of acoustic resonators which each comprise an elongate resonance volume with an open end and a closed end and a length between the open and the closed end, said open end being arranged near the angular tip portion, and said length being substantially equal to k/4*λ, wherein k=1, 3, 5, 7, . . . , and λ is the wavelength of an acoustic wave caused by mechanical vibrations of the angular tip portion.
