6.2 HF shielded room
The purpose of a HF shielded room (Faraday cage) is to shield the inner room of the cage from
disturbing HF electromagnetic radiation. The fundamental prerequisite for this is that:
▪ the room is designed to be free of unfiltered power lines and uncontrolled electromagnet ra-
diation penetration.
▪ the room is earthed solely at the central earth point of the MR system and is otherwise elec-
trically insulated and thereby free of ground loops.
