MRI MEDICAL SHIELDED ROOMS From initial design consultation through to completion European EMC Products (EEP) o昀昀er a complete MRI Solution. EEP provide Radio Frequency (RF) shielding for MRI examination rooms in the form of a faraday cage. These faraday cages cover the requirements of all the major MRI scanner manufacturers such as Siemens, Philips Medical, General Electric and Toshiba. MRI scanners are placed inside a Radio Frequency (RF) Shielded Room to prevent external interference a昀昀ecting the 昀椀nal images. All MRI shielded rooms are RF Tested on completion to standard IEEE 299 Standard Method for Measuring the E昀昀ectiveness of Electromagnetic Shielding Enclosures. IN-HOUSE DESIGN No two rooms are the same! EEP have over 25 years of experience designing and installing MRI rooms. From either construction drawings or a site inspection, EEP design team will create the faraday cage to suit your host room. Drawings will show details of the faraday cage structure, door & window positions, ceilings, 昀椀lters, penetrations & room 昀椀nishes. Once design drawings have customer approval, EEP commence manufacture of the faraday cage ready to meet your pre-determined installation date. +44 (0)1799 523 073 | [email protected] | www.euro-emc.co.uk

MRI FARADAY CAGE When creating an RF shielded room, EEP construct a faraday cage using copper clad panels. Acoustic insulation is 昀椀tted and the necessary electrical power and data cabling is installed along with various services, all of which are shielded using suitable 昀椀lters. A breakout area of any wall or roof area can be incorporated for ease of magnet delivery or removal. MRI ROOM DOOR The MRI shielded door is an important part of any MRI shielded room, therefore the design and quality of the construction is essential. MRI shielded doors reduce the electronic interference, as well as operating as an acoustic door. The doors can be manufactured to be manually or pneumatically operated with varying acoustic requirements. MRI ROOM WINDOW Being able to see a patient during an MRI scan is important both for the clinical sta昀昀 and for the patient. As well as needing good visibility, the MRI window must o昀昀er the same level of shielding as the rest of the faraday cage. The EEP window has two layers of blackened mesh to meet the RF performance. These must be positioned at a precise angle to each other to prevent visual distortion called fresnel interference. EEP can supply windows of varying sizes and frame designs. MRI INTERNAL FINISHING Once the faraday cage is complete EEP can o昀昀er the follow internal 昀椀nishes: • Internal Wall cladding either using High Pressure Laminated Wall Panels (HPL) or wall board and plastic 昀椀nishes. • Non-ferrous suspended ceiling installation populated with high grade commercial ceiling tiles. • Choice of 昀氀ooring from medical grade commercial vinyl. • Flooring to include welded seams and cap and cove around perimeter. • Internal decoration, where necessary, to match surrounding areas. +44 (0)1799 523 073 | [email protected] | www.euro-emc.co.uk

WAVEGUIDES & PENETRATIONS EEP design, manufacture and install a wide range of RF (radio frequency) shielded waveguides and penetrations which include medical gases pipework, 昀椀bre optic pipe penetrations, gas & water pipes and air conditioning ducts. Fibre optic cables or gases can be fed through dielectric material penetrations without degrading the performance of a shielded room. MRI MAGNETIC FIELD SHIELDING Shielding against magnetic 昀椀elds is crucial in any MRI installation for the safety of people, the MRI scanner itself and other medical equipment in the surrounding area. Magnetic 昀椀elds are generated by permanent magnets, electromagnets, electric motors, electrical distribution systems and MRI scanners. When these magnetic 昀椀elds need to be contained or controlled, EEP can design and install shielding. Shielding against magnetic 昀椀elds created by MRI scanners is extremely important to ensure that: • MRI scanners are una昀昀ected by nearby ferrous masses (e.g. lifts or vehicles). • Medical equipment in an adjacent area can function without interference. • Shielding ensures that a safe environment is created for people 昀椀tted with electronic implants such as a pacemaker. Prior to commencing the full design and installation of the physical magnetic 昀椀eld shielding, EEP can also plot the magnetic lines of force to verify where the magnetic 昀椀eld strength is located. MRI QUENCH PIPES At EEP we are well versed with the cryogenic engineering practices required to cope with the physical impact on the MRI quench pipe system that a helium discharge produces. Helium quench pipes form a crucial part of any super conducting MRI scanner installation. In an emergency, the potentially lethal gaseous liquid helium used in the scanner must be vented directly and safely into the atmosphere, therefore it is paramount the quench pipe system withstands the drastic shift in temperature from ambient to that of liquid helium (-269°C / 4° Kelvin) within seconds. All our installations adhere to stringent installation standards. +44 (0)1799 523 073 | [email protected] | www.euro-emc.co.uk

MRI LIGHTING – SILENTLITE® The Silentlite® lighting system is a complete MRI lighting solution. The controller contains the power supply unit, control boards, back up batteries and RF 昀椀lters. It is mounted on the outside of the faraday cage. All connections are 昀椀ltered, therefore no radio frequency interference is induced, conducted, or radiated into the chamber. Silentlite® produces virtually no electromagnetic emissions and consumes just 25% of the power of halogen lighting, helping reduce energy costs. The LED panels are extremely lightweight and 昀椀ts within a standard 600mm x 600mm ceiling grid for easy installation. MRI LIGHTING – SILENTLITE® VIRTUAL SKYLITES Silentlite® virtual skylites and virtual wall panels are a high-de昀椀nition image, MRI compatible, decorative LED panel mood lighting system. The LED picture panels are positioned ideally to provide a focal point for the patient and their aim is to assist in creating a more calming and relaxing environment whilst they undergo their scan. The picture ceiling also aids in making the room feel less clinical. Our Virtual Skylights are not solely for use in MRI rooms. Both ceiling and wall panels can be manufactured for use in a variety of healthcare facilities/areas such as X-Ray Rooms, CT Rooms, Dental Practices, Clinics and Consulting Rooms. They can be 昀椀tted as a standalone product against an existing lighting system. MRI POWER FILTERS Power Line Filters can be used to supply power to the entire MRI room, providing shielding e昀昀ectiveness within the room itself. Power line 昀椀lters for MRI rooms range from 5A to 63A and are required to protect equipment within a shielded area from the damaging and disrupting e昀昀ects of electromagnetic signals. Control Line Filters can be used to supply power to instruments and equipment within a shielded environment. These 昀椀lters suppress the electrical noise outputted by various connected electrical equipment at high frequencies, helping towards reducing the total amount of electrical noise within the shielded environment. Control line 昀椀lters are available from 2 to 12 line. Signal Line Filters are versatile pieces of electrical 昀椀ltration which generally are a low current 昀椀lter that is small in size and works at high frequencies which help to reduce the noise to the equipment. Signal line 昀椀lters are generally used for telephone, data, communication cabling or 昀椀re alarms. Much like the control line 昀椀lter they suppress the electrical noise, are generally smaller in size and o昀昀er the same performance required for the speci昀椀c application. The signal line 昀椀lters are available in 1-12 line. MRI ROOM RF TESTING & MAINTENANCE On completion of an MRI room, EEP conduct a full RF test of the room to ensure conformance. To improve longevity of MRI Rooms it is recommended to conduct regular maintenance of the MRI room. EEP can o昀昀er maintenance and servicing contracts to suit. +44 (0)1799 523 073 | [email protected] | www.euro-emc.co.uk
