Specialized construction firms (such as ETS-Lindgren or National MRI Shielding) are generally enlisted in the design and building oversight for the RF-shielded magnet room. For RF shielding, EEP generally uses aluminium or copper (sheet or foil) and under certain conditions, galvanised steel to form the Faraday cage. EEP also design and install the associated quench system as well as magnetic field shielding to support the MRI installation. EEP creates an electromagnetic sterile zone in the form of a Faraday cage complete with appropriate electrical filtration supported by EEP shielded equipment enclosures if required. Together these elements go to form a continuous RF shield around, above and below the MRI scanner. Together these elements form a continuous RF shield around, above and below the MRI scanner.
We provide RF shielding - sometimes referred to as a 'Faraday Cage', to cover a wide frequency range from below 1kHz to 40GHz.
The critical Faraday cage is constructed using pre-formed aluminium panels, an EEP shielded RF door and generally a laminated mesh window as well.
EEP Shielded Faraday Cage installations are used to RF shield all types of permanent and superconducting magnet MRI scanners.


Protection generally comprises a Faraday cage coupled with the necessary surge suppression systems. Such a conductive box used to shield out stray electromagnetic interference is also known as a Faraday cage. EEP provides RF shielding for MRI rooms – in the form of 'Faraday Cages', which cover the requirements of all the major MRI scanner manufacturers. 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. 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.
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.


To function properly, an MRI scanner needs to sit in a special room or chamber shielded against Radio Frequency (RF) interference. Appropriate physical access points to the Faraday cage are provided, including a ceiling void access hatch. At the range of frequencies used for MRI the skin conductive depth for copper is very small (on the order of 0.1 mm), meaning that only a thin layer of metallic shielding is required. EEP installations are used to protect MRI scanners, buildings, rooms, cabins or transportable containers. The schematic illustrates the various components that go into making up a typical EEP MRI room. As a pre-cursor to building the room, EEP can also undertake an optional site vibration survey to ensure the ground conditions meet with MRI manufacturers’ specified limits.

    Oneself from the fact of a Pole Shift, only time will tell will enter an obstacle course that.
