Impervius RF/MRI

RF and MRI shielding products each need to be designed to serve very specific needs. NELCO offers the strength and flexibility of our MRI Galvanized Panel System, the durability and versatility of our MRI Soldered Copper System, and the blocking and containment abilities of our MRI Magnetic Shielding. NELCO can design the systems, provide quality materials, install the components, and conduct final RF compliance testing. We also upgrade existing shielded rooms to allow for new MRI units, hospital renovations, and aesthetic improvements. Present your situation to NELCO, and we’ll present you with the best system.

1MRI Copper Panel System

The IMPERVIUS modular wood frame, copper-wrapped RF Shielding System is by far the most sought-after shielding solution for many reasons. Over 70% of all MRI sites are shielded with a modular copper panel shielding system. All components required for the RF shield are provided and installed by NELCO Worldwide, including RF door, RF window, RF filters & waveguides. Site-specific magnetic shielding and MRI-specific equipment interfaces are also installed by NELCO Worldwide.

Features & Highlights

Fire-retardant wood frame, wrapped with high-quality copper, offers walls that are self-supporting and lightweight ceiling panels (2.4 lb/ft2) which reduce the load on parent ceiling structures.

Modular panels are mechanically bolted into place and are easily disassembled for magnet delivery into the RF shield and close up.

Copper shielding material is the best shielding material to resist galvanic corrosion, providing longevity exceeding the life of the MRI equipment.

Lightweight, modular bolted-panel design allows for fast installation and lends itself to support the constructibility of most architectural room designs.

RF attenuation exceeds the requirements of all MRI vendors.

Interface to the RF shield with all other trades is simple and straightforward.

FAQs

Do you test for leakage?
Yes, NELCO tests all installed MRI shielding systems twice – once after installation, and once again after all finish work is completed.

Does NELCO offer full design and construction service for MRI/RF rooms?
Yes. We can act as a single-source solution providing full design and construction services. We’ll design the system, provide quality materials, install the components, and conduct final RF compliance testing. We also specialize in upgrading existing shielded rooms to allow for new MRI units, hospital renovations, and aesthetic improvements.

2MRI Soldered Copper System

When you trust the company, you trust the product. For optimal resilience, our Soldered Copper Sheet Shielding System combines the durability of copper with the versatility of material that can be formed into any shape for a completely custom fit. To ensure an impenetrable RF seal, we solder all joints, and then follow up with complete attenuation and ground testing. NELCO also offers a robust selection of site options and accessories to customize your copper shielding system. You can depend on lasting durability from NELCO.

Features & Highlights

Versatility
Soldered copper easily conforms to whatever the shape/design of the room layout; odd angles, multiple corners, etc… do not require additional time/cost;

Time Savings
Requires least fabrication time, fastest shipping time

Design
Seams form a monolithic RF membrane, so no mechanical joints

Testing
Meets or exceeds all MRI vendor specifications

3MRI Galvanized Panel System

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.

Features & Highlights

Versatility
In addition to RF shielding, Galvanized panels provide some level of 50/60 hz EMI protection

Durability
Sturdy panel structure not easily damaged in onsite construction

Time Savings
Fast onsite installation of panels, including floor shielding

Modularity
Panel system is easily disassembled and reassembled.

Testing
Meets or exceeds all MRI vendor specifications

Warranty
Standard 5 year warranty

FAQs

Do you test for leakage?

NELCO’s RF and MRI shielding solutions are engineered to eliminate interference, optimize performance, and ensure secure, reliable environments for medical, industrial, and research applications alike.

4MRI Magnetic Shielding

The challenge of complete MRI shielding is that it must serve two opposing purposes: In addition to blocking out distorting radio frequencies, it must also contain the 5-gauss magnetic field within the controlled area. NELCO Magnetic Shielding keeps the magnetic field generated by the MRI from expanding into adjacent areas such as patient waiting rooms, spaces used for other modalities, and service areas used by staff. Because each site is unique, and the type of magnet varies, NELCO works closely with clients and MRI manufacturers to confidently address every specific need.

5MRI Windows

MRI windows must serve a dual purpose: Block out distorting radio frequencies, and contain the 5-gauss magnetic field within the controlled area. NELCO windows keep the magnetic field generated by the MRI from expanding into adjacent areas such as patient waiting rooms, spaces used for other modalities, and service areas used by staff. Because each site is unique, and the type of magnet varies, NELCO works closely with clients and MRI manufacturers to confidently address every specific need.
