Finished Room Requirements; Walls; Penetration Wall Closet - GE SIGNA Voyager Pre-Installation

6 Finished Room Requirements

1. Non-ferrous/non-metallic materials or components should be used in the Magnet room
2. Ferrous components or material in the Magnet room that could be removed for servicing,
cleaning, or replacement must be secured to prevent the ferrous material from becoming a
projectile (ferrous components or material must also be identified as ferrous to prevent
untrained personnel from working on the ferrous material while the magnet is energized)

6.1 Walls

See Acoustic Room Specifications. Hard, bare wall surfaces may create a harsh scan room
environment. Finished walls with acoustic detailing can reduce reflected noise.
1. GE Healthcare recommends walls to protect the RF shielding
2. Walls and any millwork, permanent casework, cabinets, storage areas, acoustic coverings,
etc. must remain outside the minimum service area
3. Metallic electrical conduit inside walls and ceilings may be used. Conduit for receptacles
must be metallic

6.2 Penetration Wall Closet

An enclosure (i.e., PEN closet) must be provided to restrict access to the PEN panels and for
storage of excess interconnections. The ISC and ICC Pen Panels may be enclosed by Single
Closet (ISC & ICC side by side) or separate closets.
1. The PEN closet must meet the minimum PEN Wall closet outline shown in
and ICC Wall Opening
2. The PEN closet may be expanded to provide an area for excess cable storage with the
following requirements:
a. Excess cable must not interfere with access or servicing of the ISC or ICC PEN Walls.
b. The area within the PEN closet to store the cable should be sized to accept a 11.8 in
(300 mm) cable loop.
3. PEN closet must allow free air exchange of 400 cfm (680 m
room and PEN closet for MR system blowers. Airflow may be achieved through door louvers
or other openings in the PEN closet that meet all other PEN closet requirements
NOTE: The primary source of airflow must be from the Magnet room. Openings into the
area above a false ceiling or other storage areas should be minimized.
4. The doors of PEN closet must NOT interfere the access to remove the each cabinet's PEN
Wall cover.
