HARDWARE REQUIREMENTS
The CT Sim 5.2 software has been validated using the computer
and flat screen monitor normally provided with the system. If
Gammex supplied computer and monitor are not used, Gammex
cannot guaantee the functionality and performance of the CT Sim
5.2 Software.
If the computer Gammex normally supplied is not used, the
following minimum requirements must be met:
Minimum Requirements, non-Gammex supplied Computer
Microsoft Windows 2000 operating system
Intel Pentium-based 1 GHz microprocessor
1 GB free hard drive space
128 MB RAM
Network Interface card 10/100
CD-ROM Drive
256 color 800 x 600 display adapter
2 Serial/Com Ports
It is very important that only the operating system and the
Gammex 5.2 Software is installed on the computer. Gammex
recommends Dell computers. The functionality and performance of
any system not using the computer normally supplied by Gammex
must be verified by the assembler of the system.

1. Introduction
PRODUCT DESCRIPTION
The Gammex CT Sim Laser System consists of one to several
moveable crosshair lasers (the actual number of lasers depends
upon the laser system), a handheld pendant keypad, a power/control
box, and a PC controller, which are operated by the CT Sim 5.2
software. These lasers define the planes in the CT Simulator room.
A calibration phantom is also included.
A3000A System
This red laser system consists of a moveable ceiling laser,
defining the X plane, and two moveable side wall-mounted lasers,
defining the Z plane.
A4000A System
This red laser system consists of a moveable ceiling laser,
defining the X plane, and two side wall-mounted fixed lasers.
A3100G System
This green laser system consists of a moveable ceiling laser,
defining the X plane, and two moveable side wall-mounted lasers,
defining the Z plane.
A4100G System
This green laser system consists of a moveable ceiling laser,
defining the X plane, and two side wall-mounted fixed lasers.
2. Installation Planning Considerations
Gammex laser alignment systems provide an accurate, repeatable
optical aid for patient positioning. Proper room preparation ensures
precision, maximizes the alignment accuracy and expedites the
installation.
This pre-installation guide presents the preferred methods for stable
mounting of Gammex laser alignment systems. These techniques
should be used for all new construction and can be used with existing
rooms. With new construction, it is essential that these requirements
are incorporated into the room plans as early as possible. For
existing rooms where optimal methods cannot be used, alternate
methods are described. All of the procedures focus on providing
stability for the laser system, since even a slight motion or shift can
degrade performance.
Additional technical support is available from Gammex RMI Service
Representatives, who are available to work with facility planners,
architects and hospital personnel throughout the planning and
installation process. Gammex RMI can be contacted at 1-800-232-
9699 or 1-608-828-7000.
NOTE: These lasers allow for direct mounting on angled
walls without the use of unsightly and potentially unstable
wall brackets. In cases where the walls are not accessible we
offer stable laser stanchion systems to meet every need.

CT Sim Laser Alignment Systems
3. Room Preparation
The primary concern for laser accuracy is stability. If stability is
compromised, it will result in inferior performance. In all cases, it is
important that the mounting surfaces are flat. Concrete subwalls
provide the optimum mounting surface. However, this is not available
in most CT rooms. Adding an aluminum/steel plate is needed in most
cases.
If architectural drawings are available use them to determine the
isocenter and plate location.
For drop ceilings, please do not install the ceiling tiles until installation
is complete. Ceiling tile support runners should not cross over or
obstruct the laser. A minimum of four inches clearance is needed for
cover removal.
MOUNTING TO CONCRETE
No aluminum or steel plate is needed. The minimum space required
is 54 x 15 in. (137 x 38 cm) (H, W) of bare concrete. The center of
the concrete space should be placed at CT isocenter height, 600 mm in
front of the CT scan plane. See figures 1 and 2. Use the mounting
hardware provided.
MOUNTING TO UNISTRUT
A steel, or preferably aluminum mounting plate, is required with
minimum dimensions of 54 x 20 x 3/8 in. (137 x 50.8 x 0.95 cm)
(H,W,D). The plate thickness should not exceed 5/8 inch (1.6 cm).
The center of the mounting plate should be placed at CT isocenter
height, 600 mm in front of the CT scan plane. See figures 1 and 2.
MOUNTING TO EXISTING WALLS
An aluminum mounting plate of sufficient width to span three studs is
required (minimum 20 in.) A steel plate may be substituted with wood
stud construction, but should not be used with metal studs. The plate
should have minimum dimensions of 54" high by 3/8" thick (137 x
0.95). Thickness should not exceed 1/2 in. (1.27 cm). The center of
the plate should be placed at CT isocenter height, 600 mm in front of
the CT scan plane (See figures 1 and 2). Use 3 3/4 in. Number 12
hardened steel deck screws to mount the aluminum plate to the wall
studs (see the deck screw mounting configuration at right).
NOTE: A solid mounting to the studs is required. Mounting
plates must not be attached directly to drywall. Do NOT cover
the plates with drywall after installation.
The wall mounting location must be level to provide a planar surface
for the laser and to allow the laser beams to project perpendicularly to
the isocenter height but located 600 mm out of the scan plane. In
some cases a stand off bracket may be required for the ceiling laser.
This plate can be mounted 3.5 in. (8.9 cm) above the finished ceiling
for flush mount lasers. If room is not available above the ceiling, the
plate can be mounted flush with the ceiling or just below.
NOTE: Walls at an angle to the CT scan plane require special
consideration. Please see Figure 2 and Page 4.

4. Considerations for Angled Walls
The chart below is to help determine the plate shift needed so that
the mounting plate will be centered properly. Plate shifts should
always be towards the smaller angle. See figure 2 on page 3 and
figure 3 on this page.
Walls angled 80-90° will not need a plate shift
Walls angled 75° will need a 1 /2" plate shift
Walls angled 70° will need a 1" plate shift
Walls angled 65° will need a 11 /4" plate shift
Walls angled 60° will need a 111 /16" plate shift
Walls angled 55° will need a 2" plate shift
Walls angled 50° will need a 21 /2" plate shift
Walls angled 45° will need a 3" plate shift
Figure 3: This
illustration shows how
to determine the offset
needed for mounting
templates on angled
walls. Place a protractor
or similar device where
the string or laser line
contacts the wall to
measure the wall’s angle
to the scan plane.

Electrical and Network Requirements
Pre-Installation Guide
5. Electrical and Network Requirements
Note: There should not be ground potential differences
between the PC ground and the controller box ground.
If so, equipotential grounding or additional protective
grounding must be provided.
A separate, 1 inch minimum metal conduit, raceway or equivalent
should be placed between the three lasers and the control room
where the computer will be located. Three separate 110/220 volt
outlets will be needed to power the computer, monitor and controller
box in the control room. See Figure 4
An IP address/default gateway and sub net mask should be
available to Gammex at the time of Installation.
A live network connection along with network cable should be
provided.
The system can be wired as a branch or series circuit.
See Figure 5 on page 6
Figure 4: Conduit Wiring Diagram
Junction Boxes for Z1 and Z2
should be at the bottom or bottom
left of the laser. For the X laser,
mount the junction box on the left
when viewed from the foot of the
treatment couch.
