Radio Frequency Shielding NuShield® is used to block Radio frequency waves for noise and artefact free Imaging in MRI Scanner, Good and long-lasting RF Cage is most essential part of a MRI Scanner, Our RF Cages made of Copper and Galvanised Iron assures more thank 100db attenuation and installed according to OEM specifications. The NuShield® RF Doors designed and manufactured in our factory carries lifetime warranty and ensures trouble free operations.

The patients with claustrophobia will find difficulty in staying longer period inside MRI bore due to is narrow tunnel and gradient noise, To give comfort to patients a patient centric ambience is very much essential for MRI Exam Room. Our Customised Interior solutions consist of Picture Ceiling Made of MRI Compatible LED lights and Drivers, Wall Vinyl with choice of pictures as per customer choice, GI, Aluminium or Gypsum False Ceiling, Choice of High-quality Vinyl Floor, Acoustic insulation and Decorative acoustic Boards Makes RF Shielding more Beautiful. RF Cage Can be decorated with various ambience solutions Like MRI compatible Projector, RGB Lights, In-Bore Experience etc. to enhance patient experience and comfort.

Passive Shielding is used to restrict 5 Gauss line within limits to enable people movement close to MRI Room. Passive Shielding is made of Non grain oriented electrical low carbon (< 0.006%) silicon iron B/H Hc 90A/m or less (less = better) as per the recommendation given by OEM. Generally Passive shielding calculation are done by OEMs Only.

MRI equipment generates strong RF (radio frequency) interference which can disrupt smooth working of other electronic equipment in the nearby vicinity. Vice versa, external RF signals may be picked up by the MRI system which will adversely impact the accuracy of the imaging data. Thus MRI rooms have to be effectively shielded from both incoming and outgoing RF interference. To provide RF shielding, a Faraday’s cage have to be build to cover the MRI scan machine with varied metals like Copper, Galvanized Iron and Aluminium depending on numerous specifications and customer requirements. The shield should have good attenuation of more than 90DB to perform which will isolate the MRI scan machine from rest of structures of building, electronics equipment’s etc.

The critical MRI scan room is shielded using a pre-formed Aluminum/copper/galvani ed iron panels, a shielded RF door and laminated mesh window.All other services in room such as air condition,helium vent,water supply, medical air, fire fighting systems are routed through specialized waveguides mounted on walls. All these elements will form ‘NuShield’, a comprehensive RF shielding solution.

<ul> <li>Nushield is basically a Faraday cage constructed of panels of high-quality copper foil,Aluminum or Galvanized Iron</li><li>The self-supporting structure of pre-fabricated wall elements makes them independent of the surrounding walls,greatly simplifying assembly and installation.</li><li>All fittings are non magnetic materials. Doors, windows and penetrations for supply services are also shielded or fitted with filters to prevent RF leakage.</li><li>RF enclosures are delivered to site in prefabricated modules or assembled by NuMed trained technician thus consuming lesser turn around time.</li><li>With the exception of the floor, the RF cage can be dis-mantled and erected at another location if necessary.</li>/ul>
