Magnetic Resonance Imaging (MRI) machines are incredibly powerful tools — but they’re also very sensitive. That’s why proper MRI shielding, including an MRI Faraday cage and mri magnetic shielding, is essential for safe, accurate scans. In this article, we’ll explain what these terms mean, why they matter, and how National Shielding delivers world-class solutions.
Why MRI Shielding Is Crucial
MRI scanners generate strong magnetic fields and radio-frequency (RF) emissions. Without proper shielding, these can cause electromagnetic interference (EMI), which degrades image quality or even disrupts scanner performance. That’s where MRI shielding steps in. National Shielding has been designing and installing specialized shielding systems for over 25 years.
What Is an MRI Faraday Cage?
An MRI Faraday Cage is a shielded enclosure—typically made of copper or steel—that blocks external RF signals from entering the MRI room. RF interference can corrupt the subtle signals that the MRI scanner detects, so the Faraday cage must be highly effective. National Shielding offers premium options:
- Copper modular shielding — using pre-tested copper panels for strong attenuation.
- Copper soldered shielding — for very high shielding performance with low-profile installation.
- Steel modular shielding — which also gives some magnetic shielding benefits.
All types are manufactured at National Shielding’s Dallas facility and installed by their in-house team.
Understanding MRI Magnetic Shielding
While the Faraday cage takes care of RF interference, mri magnetic shielding addresses static magnetic fields produced by the MRI magnet itself. These powerful magnets can leak into surrounding areas, potentially affecting nearby sensitive equipment or even devices like pacemakers. To prevent that, National Shielding designs magnetic shields using specialized steel and advanced modeling software — the same tools used by MRI manufacturers.
