摘要:
An exam room shielding (10) for electromagnetically shielding a magnetic resonance imaging system (2) includes: a ceiling, a floor, side walls (11) interconnecting the ceiling and the floor, and a tubular shielding device (12), which is arranged to surround an examination tube (3) of the magnetic resonance imaging system (2). Both longitudinal ends (13) of the tubular shielding device (12) are circumferentially connected to openings (14)of the side walls (11) which form the outline of an U-shaped room (15) with the longitudinal ends (13) of the tubular shielding device (12) interconnecting the lateral flanks (16) of the U-shaped room (15). A magnetic resonance imaging system (2) includes an exam room (1), with the above exam room shielding (10). An additional treatment or diagnosis device (7) can be located at an outer circumference of the tubular shielding device (12). This separates the space inside the exam room into a compartment free of RF noise, i.e. the space surrounded by the exam room shielding, for MR scanning, and a compartment outside the shielding, in which an operator can move for operating the MR imaging system and/or preparing a person for a MR scan.
