2.4. MRI Environment Hazards
Installation of materials inside the MRI suite must be done with extreme caution and only by authorized personnel. Care
must be taken to keep ferromagnetic materials such as tools, filter plates, screws, etc. at least three meters
(approximately 1 feet) away from the energized magnet. Absolutely no work should be done near the filter panel when
a scan is in progress.
All cabling inside the MRI environment should either be connected or terminated properly. Failure to do so may
result in skin burns related to RF energy. All cables should be run straight and never looped, as this may also cause
serious skin burns inside the MRI room.
In addition, no persons with ferromagnetic prosthetic devices such as pacemakers or joint replacements should enter the
MRI suite at any time. Extremely high magnetic forces have the potential to dislodge ferrous items at high velocities that
can result in serious injury or death.

4. Room Layout Overview for Installation
WARNING: Absolutely no ferromagnetic tools should be brought inside the MRI Suite!
Below is the standard setup for the Serene Sound system. Your individual installation may vary, but will generally be
distributed in three areas: 1) Control Room, 2) Computer/Equipment Room and 3) Magnet Room.
The Control Room setup consists of placement and connection of the Serene Sound Controller, Technologist Remote Control
and Stereo system.
A single Laser Link Fiber Optics cable bundle will run from the Serene Sound Controller through the penetration panel
waveguide to the Serene Sound Transducer. With the exception of the headset, all Magnet Room Serene Sound components
must be installed to the side of the magnet shroud, also the transducer power cable should never be in parallel with magnetic
coil. Additionally, these components should be placed in a light traffic area.

5. Installing the MR Laser Link Cable and Transducer Power Supply
Cables
The preferred method of routing the fiber optic cable is to run the cable from the control room through the
overhead ceiling drop tiles and down into the computer room in front of the filter panel through the Fiber
Optics Waveguide. Excess fiber cable can be stored above ceiling tiles. It can then be run alongside the
other MRI cables going to the magnet. The cable should end where you intend to locate the transducer.
Note: Care must be taken to ensure the cable is not bent in radius of less than 15cm
(90 degrees or right angle) or damage to the optical fibers will occur.
The routing of the transducer power cables will vary somewhat depending on the facility layout and the
magnet type. For most facilities and magnets, the typical procedure would be as follows:
 Determine the length of cable needed from the location of the transducer to transducer power
supply. Note: Transducer power supply needs to be at least 1 feet from the nearest wall power
plug. If the power cable is too long RTC recommends not looping the power cable and tying it
down with the tie wraps in long circle method. See photos below.
Incorrect Method Correct Method
 Route the transducer power cable that will be used, following a similar path to the fiber optic
cable. Avoid running the power cable close and/or in parallel with the high energy RF
cables for the magnet, as the RF energy may interfere with reliable operation of the system.
