Frequently Asked Questions

RF (Radio Frequency) shielding creates an electromagnetic barrier that prevents external radio waves from entering a protected space and keeps internal emissions contained. This is critical for MRI systems, which operate at specific frequencies and require interference-free environments to produce accurate diagnostic images. Without proper RF shielding, MRI scanners experience image artifacts, reduced quality, and potentially invalid scan results.

Decibel (dB) attenuation measures how effectively shielding blocks RF signals. A higher dB rating means better shielding performance. For example, 100 dB attenuation reduces RF signal strength by a factor of 10 billion. MRI facilities typically require 100 dB or greater attenuation to meet manufacturer specifications and ensure optimal imaging performance.

Installation timelines vary based on room size and complexity. A typical MRI suite takes 2-4 weeks for complete RF enclosure installation, including wall panels, door systems, waveguides, and final testing. Larger facilities or complex configurations may require additional time. We work closely with your construction schedule to minimize delays.

RF panel systems use prefabricated modular panels that bolt together to create the shield. Board systems involve applying conductive materials (copper, aluminum, or specialized paints) directly to walls. Panels offer faster installation and easier modification; board systems provide seamless coverage and better aesthetics. Both achieve comparable attenuation when properly installed.

Begin planning at least 6-9 months before your target MRI installation date. This allows time for site evaluation, shielding specification, architectural coordination, construction, equipment delivery, and certification testing. Our team can work with your architects and MRI vendor from the earliest planning stages to ensure specifications are met.

MRI rooms require a structurally sound floor capable of supporting the magnet weight (typically 5,000-15,000+ lbs for clinical systems). The floor must be non-conductive or properly grounded to prevent interference with the magnetic field. We coordinate with structural engineers to ensure the floor meets all requirements before shielding installation begins.

Yes. MRI room doors must be RF-shielded with continuous conductive gaskets to maintain shield integrity when closed. Standard observation windows can be replaced with RF-shielded glass panels that include conductive mesh or coating. These components are essential for achieving required attenuation levels while allowing visibility and safe access.

Waveguides are tube-like passages that allow cables, pipes, and vents to pass through the RF shield while maintaining shielding effectiveness. They act as filters that trap electromagnetic waves at the shielding frequencies. Every MRI room requires waveguides for electrical conduit, HVAC ducting, patient monitoring lines, and other infrastructure.

Several regulations apply: The Joint Commission and state health departments require compliance with facility standards; NRC governs radioactive materials; FDA regulates MRI as a medical device. Additionally, MRI manufacturers (Siemens, GE, Philips, Canon) publish specific installation requirements that must be followed for warranty validity and optimal performance.

RF shielding should be tested after initial installation, after any structural modifications, and periodically as part of quality assurance programs. Many facilities include annual attenuation testing in their compliance protocols. We recommend testing whenever doors are replaced, new penetrations are created, or after any construction work near the shield.

ALARA stands for "As Low As Reasonably Achievable" — a radiation protection principle that minimizes exposure to patients and staff. For diagnostic imaging, this means using appropriate shielding, dose optimization protocols, and only performing scans when medically necessary. Our shielding solutions support ALARA compliance across all imaging modalities.

This depends on adjacent spaces. MRI itself doesn't produce ionizing radiation, but if the room also houses CT, X-ray, or PET equipment, lead shielding may be required for those modalities. We assess each facility's layout and adjacent room uses to determine if radiation shielding (lead) is needed in addition to RF shielding.

We specialize in RF shielding, specialized wallcoverings, and surface engineering. We coordinate with your general contractor for structural work, electrical, and HVAC. Our project managers oversee the shielding scope and ensure integration with other trades for a complete, turnkey result.

Yes. We frequently upgrade existing MRI facilities to accommodate newer, higher-field systems (e.g., upgrading from 1.5T to 3T) or to address shielding degradation. Upgrades may involve adding shielding layers, replacing doors, modifying waveguides, or complete shield replacement depending on the situation.

Our installations include a comprehensive warranty covering materials and workmanship. We also offer ongoing maintenance contracts that include periodic testing and certification. Specific warranty terms are outlined in project proposals based on scope and specifications.

We provide installation services throughout the continental United States. Our teams are strategically located to respond quickly to projects nationwide. For projects outside this area, we work with trusted regional partners or can arrange specialized installation teams as needed.
