RF Shielding for the BSD-2000

Affordable, fast installation, alternative to traditional RF shielding

Add RF shielding to any space without the major disruption construction can cause. Using high efficiency LED lighting with existing air handling, fire alarm and suppression. Most installations can be completed in three days.

Create a site plan. The average size cage is 12' x 16', but the modular design allows for flexibility in layout. The floor is raised to allow for cabling.

Start with an empty room. Check your site plan to determine power requirements for the Pyrexar BSD-2000 system.

Using the site plan, tape out the cage footprint. The BSD-2000 is operated from outside of the cage area, so plan for a user workstation and RF amplifier placement

Unpack all of the kit components. Place the heavy duty nylon sheet over the work area in order to isolate the RF shielding from the building.

Place all of the base frame connectors in their approximate location, being mindful of the cable trough placement.

The modular design allows for manufacturing and installation efficiencies. Floor supports are identical lengths and are connected using hex bolts.

Installed uprights are connected with overhead crossbeams.

Crossbeams continue providing increasing stability as the structure forms. The door frame will be located to the left in this example.

Pre-cut heavy plywood panels drop into the frame to create the sub-floor.

Once the floor (and the cable trough) is installed, mesh wall panels are installed between the frame uprights.

The door panel assembly is installed. A ramp will be added to accommodate the step up into the cage.

The cage system has a variety of floor finishes. Grey vinyl flooring that best matched the existing room is used in this example.

A filter panel is built in to prevent RF leakage between the Sigma Base and the RF amplifiers.

One of the primary benefits of the mesh shielding is that it allows constant communication between the patient and the operator. Interior lights provide work room illumination and create wall transparency from the outside in. Lowering the interior lights and illuminate the outer room for the ability to see outside the enclosure.

The BSD-2000 generates Non-Ionizing Radiation, in the form of radio frequency (RF), during deep regional hyperthermia treatments. Phased Array RF energy excites cells in the body, producing cell friction, which generates localized heat.  Stray RF field emissions can interfere with communication products, like FM radio.  Much like the EMF shielding required for MRI systems, the US FCC (Federal Communications Commission) requires the blocking of these competing frequencies from leaking out of the treatment room.

Shielding can be an expensive and disruptive process for any cancer treatment center. There is a high quality, lower cost, solution alternative*, that can be installed without affecting the existing lighting, air handling, fire monitoring, and fire suppression systems. This product is modular and can be installed in as few as three days by a small installation crew. For an overview of the installation process, see the slide show above.   Go to the MROSB website for more information, or price quote.
