MRI Magnetic Shielding: Ensuring Safety and Clarity with National Shielding

Magnetic Resonance Imaging (MRI) is one of the most advanced diagnostic technologies in modern healthcare. However, installing an MRI system comes with unique challenges. One of the most crucial requirements is MRI magnetic shielding, which protects both the scanner and its surroundings from magnetic and radiofrequency (RF) interference.
At National Shielding, we specialize in delivering world-class MRI magnetic shielding solutions for hospitals, clinics, and diagnostic centers. With years of experience, our team ensures safety, compliance, and high-quality imaging results.
What is MRI Magnetic Shielding?
MRI machines use strong magnetic fields and RF waves to generate detailed images of the human body. Without proper shielding, these fields can interfere with surrounding equipment, or worse, affect patient and staff safety.
MRI magnetic shielding involves creating a controlled environment by using specialized materials such as:
- RF shielding (copper or aluminum) to block external radio signals.
- Magnetic shielding (steel plates or laminations) to confine magnetic fields.
This ensures that the MRI operates at peak performance while minimizing external disruptions.
Why is MRI Magnetic Shielding Important?
1. Patient and Staff Safety
MRI machines generate strong static magnetic fields (up to 3 Tesla or higher). Without shielding, these fields can extend beyond the scanner room, attracting metallic objects and creating dangerous projectiles. Shielding ensures the magnetic field is contained.
2. Accurate Imaging
RF interference from mobile devices, Wi-Fi, or nearby electronic equipment can cause noise in MRI images. Proper shielding eliminates distortion, guaranteeing clearer diagnostic results.
3. Regulatory Compliance
International healthcare standards mandate shielding for MRI installations. Hospitals must meet these standards to operate MRI facilities legally and safely.
4. Protecting Equipment
Sensitive medical equipment outside the MRI suite can malfunction due to magnetic interference. Shielding safeguards other hospital devices.
Components of an Effective MRI Magnetic Shielding System
At National Shielding, we design shielding solutions tailored to each facility. The main components include:
🔹 RF Shielding
- Copper or aluminum panels create a Faraday cage.
- Prevents unwanted RF signals from entering or leaving the MRI room.
- Ensures image clarity by blocking interference.
Magnetic Shielding
- Specialized steel plates or laminations redirect and absorb stray magnetic fields.
- Protects nearby spaces from magnetic interference.
🔹 Magnetic Shielded Doors and Windows
- High-performance doors with copper mesh or steel layers.
- Observation windows with RF shielding glass.
Ventilation and Waveguides
- Airflow systems designed to maintain shielding integrity.
- RF-tight filters allow ventilation without interference.
