Warning
WAR NIN G
.The MR400 shall meet its full function and performance specifications when
positioned in the MR room of a 3T magnet, up to the 5000 gauss line, 4W/kg
SAR, and 7.2 µT B1
rms
in all orientations. Always secure the MR400’s wheel
locks when the unit is placed within the MR system room. Failure to properly
position the MR400 and its accessories in the MR system room will result in
system or accessory failure, and possible patient or user injury.
CAUTIONS
If the MR400 rolls to the face of the MR system due to magnetically induced pull force, do
not attempt to dislodge the MR400 by pulling from the display panel or guide handle;
instead, dislodge the MR400 by gently pulling from the lowest point of the base. This will
prevent the base of the unit from experiencing higher MR pull forces in the vertical
direction.
Position the MR400 in a manner which does not block access to the device or wall plug
connectors.
Field strength variations in a particular MR system room (which may be due to active
shielding technology, manufacturer variability, future enhancements, etc.) can make
distinguishing the 5,000 gauss level (as measured from the center line of the MR bore)
difficult. These variations may require moving the MR400 away from the MR system if
system abnormalities or malfunctions are observed. Prior to clinical use, ensure that the
allowable distance of the MR400 from the MR system is maintained for proper operation.
