Project Description

Automatic RF door for MRI applications

The door of the MRI examining room is one of the key elements of an RF shield. It must reconcile the perfect RF tightness with robustness and ease of use. ITEL provides an innovative automatic door, accurate in every detail to meet all needs.

Made with the best materials, the automatic door uses a compressed air mechanism to ensure the RF sealing, yet maintaining an opening and closing of the door with minimum effort of the operators. The RF contact is guaranteed with a conductive gasket, which replaces the traditional “finger”, thus minimizing the demands of maintenance and repair. Together with the door is provided a silenced air compressor, with automatic condensate drain to reduce the need for maintenance of the same.

The RF contact mechanism, automatically activated on opening and closing, foresees an automatic unlocking in the event of lack of compressed air, always guaranteeing the possibility of entry and exit from the MRI room according to the highest hospital safety standards.

The lack of height difference between the threshold and the room floor allows easier access for stretchers and wheelchairs, in order not to cause any inconvenience to patients and operators.

Particular care was taken in the design of the door, in particular as regards sound insulation. By using sound-absorbing materials of greater thickness and special devices in the structure, a good noise reduction is achieved, useful in particular sequences of the MRI machine.

The reinforced frame, brushed steel, and the strong hinges, custom designed for the automatic door, ensure opening and closing unchanged over time, thus ensuring the long-term RF and sound isolation.

The exterior and interior sides of the door can be provided in standard hospital Blue or White (other colours available as an option).
