DO NOT take the DSP box, filter box, or power supply into the magnet room. These items are
MR-unsafe.
Radio-frequency heating
The metallic housing and the cables of the camera can absorb energy from the electromagnetic
fields of the MRI scanner. This absorption can lead to heating of the housing. The heating level
depends on the orientation of the camera and its cables relative to the MRI scanner and on the
imaging sequences used. Therefore the temperature of the camera should be checked before it
is touched and no inflammable objects should be attached to the camera.
The camera is tested with different orientations of housing and cables. However, it is not
possible to check all possible situations which might occur in different applications. The cables
can act as antennas and disturb the sensitively adjusted fields of the MRI scanner. If
interferences of MR images or video images occur, one should try to change the directions of the
cables.
Radio-frequency burns
Whenever metallic parts are used in an MRI scanner there is a residual risk of an electric
discharge from this part to the human body. Do not to place the device closer than 10 cm to the
subject or the user.
The risk of an electric discharge can be further reduced if the connection cable is guided on a
direct way (without loops and without crossing the middle axis) out of the bore.
Do not drop the camera
The device is equipped with sensitive optical components. It should not be dropped from larger
heights.
The filter box is only suitable for the Camera “12M-i” with integrated LED. Connecting the
standard 12M or CS camera to the filter box will destroy the integrated electronics.
