RF cabins for MRI facilities
Wardray Premise

RF cabins for MRI facilities

MRI scanners need to be housed in a faraday cage (ie an RF cage / cabin) as radio frequency (RF) waves cause scanner interference and artefacts on MRI scans. The RF cabin shields the equipment from this external RF interference.

Depending on the size of the MRI host room and the proximity of external large moving steel objects (such as lifts & vehicles) the MRI room may require additional magnetic / steel shielding.

Wardray Premise Ltd manufacture and install RF cabins for MRI facilities, along with magnetic shielding calculations and the installation of any subsequent steel shielding required. Wardray have an installed base in excess of 320 cabins, and continue to develop their product, their latest developments include:

  • independent acoustic testing of the Wardray RF cabin with the test concluding that the “Weighted Standardised Level Difference” of the MRI booth is within the range of 40-45 DnT, w; and
  • the development of a fingerless RF door.

The Wardray RF cabin is available for customers to review at their factory in , West Yorkshire. Being able to examine an RF cage away from a building site allows potential customers to understand the construction process and obtain an appreciation of what’s hidden behind the walls of a finished MRI facility.
