RF SHIELDED EXAM ROOM OF MAGNETIC RESONANCE IMAGING SYSTEM

摘要

The present invention provides an exam room shielding (10) for electromagnetically shielding a magnetic resonance in imaging system (2), the exam room shielding (10) comprising 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), wherein both longitudinal ends (13) of the tubular shielding device (12) are circumferentially connected to openings (14) of the side walls (11), and the side walls (11) of the shielding (10) 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).The present invention further provides a magnetic resonance imaging system (2) comprising an exam room (1), wherein the exam room (1) has the above exam room shielding (10). The present invention also provides a system (6) comprising the above magnetic resonance imaging system (2) and an additional treatment or diagnosis device (7) 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.
