4. Mounting options
The device can be mounted directly to any suitable object via the two 2 mm holes in the backplate.
Standard mounting options are:
1. direct mounting of the camera using the mounting holes
2. use of an articulated arm (optional accessory) for mounting the camera e.g. to the head coil
3. use of a ball joint mount (optional accessory) e.g. for use inside the MR bore
4. use of a tripod adapter (optional accessory) for mounting the camera on a tripod
You can find photos of the optional accessories in section 11 of this manual.
5. Connection of camera/LED to filter box
The powering of the camera and the LED is arranged via the filter box. The camera/LED is
connected to the filter box with the shielded camera connection cable which includes the power and
the signal lines.
The filter box prevents the transmission of disturbing signals into the MR cabinet. It avoids
interferences in the video signals and the MRI imaging.
The filter box includes a low pass filter that suppresses frequencies higher than 1 MHz with over 100
dB. This filter prevents damage and interferences caused by the high frequency signals of the MR
scanner. In addition, the filter box includes an optical isolation of the video signals. In that way a full
separation of the MRI equipment from the external power network is guaranteed.
Note:
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!
