EEP provides RF shielding for MRI rooms – in the form of 'Faraday Cages', which cover the requirements of all the major MRI scanner manufacturers.
MRI Shielded Room Applications:
- EEP Shielded Faraday Cage installations are used to RF shield all types of permanent and superconducting magnet MRI scanners.
Faraday Cage Specification:
- To provide Radio Frequency shielding, EEP uses aluminium, or in certain conditions galvanised steel, to form the Shielded Faraday cage.
To function properly, an MRI scanner needs to sit in a specialised room or chamber shielded against Radio Frequency (RF) interference. Without such protection the very weak RF signals that emanate from the patient when scanned would be overwhelmed.
The following schematic illustrates the various components that go into making up a typical EEP Shielded MRI room.
The critical Faraday cage is constructed using pre-formed aluminium panels, an EEP shielded RF door and a laminated mesh window. Together these elements form a continuous RF shield around, above and below the MRI scanner.
Acoustic insulation is provided and fitted behind a decorative internal lining, as well as floor and ceiling finishes. Appropriate physical access points to the Faraday cage are provided, including a ceiling void access hatch. The necessary electrical power and data cabling is installed along with various services; all of which are shielded using suitable filtration.
As a pre-cursor to building the room, EEP can also undertake optional site vibration and magnetic field fluctuation surveys to ensure the ground conditions meet with MRI manufacturers' specified limits.
EEP also design and install the associated emergency MRI helium quench system, as well as magnetic field shielding to support the MRI installation. For more information on this and our doors, see FAQ 'Shielded Doors', 'Helium Quench Pipe Systems' and 'Magnetic Field Shielding'.
