Magnetic shielding is not required for every site and is often overlooked in the early planning stages. Essentially, the goal of magnetic shielding is to protect the environment from the MRI magnetic field.

Magnetic shielding is not the same as lead shielding. Lead shielding is identified via “line of sight” whereas magnetic shielding must take into account the geometry of the magnetic field relative to the position of the magnetic shield

Magnetic shielding is usually fabricated with silicon steel in sheet form, but it can also be done in steel plate. Steel plate is not as easy to work with and tends to be more expensive whereas silicon steel is easy to manipulate. The type of material you will need should be determined by your shield designer.

In most cases, your MRI vendor should be able to provide you with magnetic shield design services. There are also independent companies who offer it. And, ETS-Lindgren offers magnetic shield design services as well. You should consider a company that is associated with your shielding vendor. If a design is poorly done, it is all too easy to finger point. An all-in-one solution is usually the best decision.

How do facilities around the globe build MRI shielding systems strong enough to consistently hold all RF shielding in place, yet flexible enough to be completely modular? They simply assign the responsibility to NELCO. Our modular Galvanized Panel System is constructed of rigid panels laminated in galvanized steel. To assure an impenetrable RF seal, we join the panels in continuous “hat and flat” and “corner cove” configurations, then follow up with ground isolation and RF attenuation tests. NELCO also demonstrates strength in selection of site options and accessories for uncompromised customization
