Medical RF Shielding for MRI Rooms
Astra Shield specializes in Medical RF Shielding for MRI Rooms, offering customized Radio Frequency (RF) and magnetic shielding solutions for leading MRI manufacturers. Our focus is on designing and installing high-performance MRI room shielding systems that precisely meet the specifications of both MRI magnet manufacturers and healthcare facilities. The goal is to ensure compatibility, patient safety, and optimal imaging performance by providing full protection against RF interference, magnetic field leakage, and ionizing radiation, all in compliance with global standards.
Astra Shield Design, Manufacture and Install the RF Enclosures as below:
- RF Shielded Enclosures : Modular cage designs using high-performance galvanized steel, copper, or aluminum panels, with integrated EMI/RFI gaskets for seamless performance and optimization for low-frequency and broadband RF attenuation.
- MRI RF Doors & Windows : Manual and automatic RF shielded doors (honeycomb or solid core), and shielded viewing windows with multi-layered glass and fine mesh technology. These are designed for frequent hospital use, ease of operation, and high durability.
- Site Preparation : This involves anti-vibration floor systems, ferromagnetic material screening, non-magnetic construction protocols, site conditioning, and coordination with OEMs and hospital infrastructure teams.
- Magnetic Shielding : Passive magnetic shielding based on site-specific fringe field analysis.
- Electrical and Ancillary Systems : Power line filters, waveguides, penetration panels, and HVAC integration, all compatible with emergency grounding and safety systems.
Astra Shield's solutions adhere to key Standards & Compliance including:
- IEC 60601-1-2 : Electromagnetic compatibility for medical devices.
- ACR Guidelines : Compliance with American College of Radiology MRI safety zones and room layout standards.
- OEM Compliance : All designs are reviewed and approved in coordination with OEM requirements and commissioning teams.
