• RF shielding for MRI
rooms is necessary to prevent noise of radio frequency from entering into the MRI scanner and distorting
the image. The three main types of shielding used for MRIs are copper, steel,
and aluminium.
• RF shielding should not
be confused with magnetic
shielding, which is used to
prevent the magnetic field of the MRI magnet from interfering with pacemakers and other
equipment outside of the MRI room.
• After the MRI room
has been completely shielded, all utility services such as electrical for
lights, air conditioning, fire sprinklers and other penetrations into the room
must be routed through specialized filters .
