Abstract (en)

[origin: WO2009031092A1] A magnetic resonance examination system comprises an examination zone (1), a gradient coil (2) to generate a gradient magnetic field in the examination zone and a cover (3) positioned between the gradient coil and the examination zone. An RF antenna (4) mounted on an antenna-carrier (5) and positioned between the cover and the gradient coil. The combination of the cover and the antenna-carrier form a double wall with a gap between them. The cover and the antenna-carrier are together located between the gradient coil and the examination zone and effectively counteract the propagation of acoustic noise from the vibrating gradient coil to the examination zone and to the outside of the magnetic resonance examination system.
