Electro-Magnetic Interference (EMI)

Note: If power sub-stations exist under or above the scan room, or near the control room, consider EMI
testing to determine if your proposed room meets the published acceptable EMI room limits. This
also includes high voltage lines under the scan or control room floor.
4.1

Gantry and Table

Locate gantry in ambient static magnetic fields of less than 10
guarantee specified imaging performance. Ambient AC magnetic fields must be below 10
(10 milligauss) peak.
WARNING GANTRY & TABLE ARE ALLOWED TO BE INSTALLED ONLY IN X-RAY PROTECTED
REQUISITES ROOMS, WHICH PROVIDE AN ATTENUATION OF AT LEAST 12dB FOR RADIO
FOR ROOM DISTURBANCES FROM 30 MHz TO 1 GHz.
(The Warning statement above is specified by IEC 60601-1-2, First Edition, 1993)
4.2

Color Monitor

Locate color monitors in ambient static magnetic fields of less than 5 x 10
to guarantee color purity and display geometry. See
4.3

Console / Computer Equipment

Locate computer equipment in ambient static magnetic fields of less than 10
milligauss) to guarantee data integrity. See
4.4

Magnetic Media

Locate magnetic media in ambient static magnetic fields of less than 10
4.5

PDU

The PDU produces an electromagnetic field that radiates outward from its cabinet in all directions.
Do not place the gantry or patient table within 0.3 meters (12 in.) of the edge of the Power
Distribution Unit. Do NOT place other sensitive electronics (e.g. the computer equipment) within 1.0
meters (39 in.) of the edge of the Power Distribution Unit in any direction, including above or below
it. See
Note: The UPS is not classified as sensitive electronics.
