MRI Shielding for the Research Environment
Research institutions and universities push MRI technology to its limits. Ultra-high-field scanners operating at 7T, 9.4T, and beyond demand shielding performance that far exceeds what is required in clinical settings. The tolerance for RF leakage is measured in fractions of a decibel, and the consequences of inadequate shielding — corrupted research data, months of lost experimental time, and compromised grant deliverables — are severe.
We have extensive experience designing and installing MRI shielding for academic medical centers, neuroscience research institutes, and university imaging laboratories. Our engineering team understands the unique requirements of research-grade installations and delivers enclosures that meet the exacting specifications these environments demand.
Ultra-High-Field Shielding Challenges
As field strength increases, the Larmor frequencies used for imaging move higher into the RF spectrum, and the scanner becomes more sensitive to external interference. A 7T or 9.4T scanner can detect RF noise that a 1.5T system would never notice. This means the shielding enclosure must provide significantly higher attenuation across a broader frequency range, with particular attention to frequencies above 300 MHz where many urban and campus RF sources operate.
Construction quality becomes critical at these performance levels. Every seam, joint, penetration, and door contact point must be executed with precision. We use proven construction techniques and premium shielding materials selected specifically for ultra-high-field performance, and we verify every enclosure with comprehensive testing before the scanner is installed.
Research-Grade Shielding Effectiveness Specifications
Clinical MRI installations typically require shielding effectiveness in the range of 80 to 100 dB. Research installations routinely demand 100 dB or more across a wider frequency band, with some ultra-high-field projects specifying 110 dB or higher at the scanner's operating frequency. Meeting these specifications requires a fundamentally different approach to design, material selection, and quality control.
We work directly with your research team, MRI physicist, and scanner manufacturer to define the SE specifications appropriate for your specific application. Every enclosure is validated through rigorous shielding effectiveness testing at multiple frequencies and measurement points, with detailed documentation suitable for grant compliance reporting and institutional records.
Animal Imaging & Preclinical MRI Facilities
Preclinical MRI scanners used for small-animal and large-animal research present their own shielding requirements. These systems often operate at very high field strengths — 9.4T, 11.7T, or higher — in rooms that must also accommodate anesthesia delivery systems, physiological monitoring equipment, and specialized animal handling infrastructure. The shielding enclosure must attenuate external RF while managing the electromagnetic compatibility of all this ancillary equipment inside the room.
We design animal imaging suites that integrate the shielding enclosure with the room's operational requirements, including proper penetration design for gas lines, monitoring cables, and ventilation systems that support both animal welfare and image quality.
Multi-Modal Imaging Suite Design
Many research institutions combine MRI with other imaging modalities — PET/MRI, MEG, EEG, and optical imaging — in integrated suites that require careful electromagnetic management. The shielding enclosure must protect the MRI scanner from external interference while also preventing the MRI system's strong magnetic field and RF emissions from disrupting adjacent sensitive instruments.
Our engineering team has experience designing shielded environments for multi-modal research facilities. We coordinate with the investigators and equipment manufacturers for each modality to develop an enclosure strategy that supports the full range of research applications planned for the space.
Our Research Installation Experience
We have completed shielding installations for research institutions across the United States, including projects involving 7T human scanners, 9.4T preclinical systems, and combined PET/MRI suites. Our team understands the academic project environment — including the complexities of university procurement, facilities management coordination, and the need to work around active research schedules.
We also understand that research installations evolve. Today's 7T room may need to accommodate a next-generation scanner in the future. Our designs account for potential EMI challenges and future upgrade paths, so your investment in shielding infrastructure continues to serve your research program as technology advances.
Frequently Asked Questions
What shielding effectiveness is required for a 7T MRI scanner?
Most 7T scanner manufacturers specify shielding effectiveness of 100 dB or higher at the operating frequency (approximately 298 MHz). The exact requirement depends on the scanner model and the site's electromagnetic environment. We work with the OEM and your MRI physicist to determine the precise specification for your installation.
Can you shield a room for both MRI and MEG or EEG?
Yes. Multi-modal suites require careful coordination of shielding strategies to protect each instrument. We work with the equipment manufacturers and your research team to design an enclosure that meets the electromagnetic requirements of all modalities in the suite.
Do you have experience with university procurement and facilities processes?
Yes. We have completed projects at numerous universities and understand the procurement, contracting, and facilities coordination processes typical of academic institutions. We can provide the documentation and compliance information needed for institutional purchasing requirements.
Can existing research MRI shielding be upgraded for a higher-field scanner?
In some cases, existing enclosures can be upgraded to meet higher SE specifications through targeted improvements to materials, doors, penetrations, and sealing. We evaluate the existing installation and recommend the most cost-effective path to achieving the required performance for your new scanner.
