Please understand their meanings clearly before reading this manual.
Signal word Meaning
DANGER Indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION Indicates a potentially hazardous situation which, if not avoided, may result
in minor or moderate injury.

2. Safety Precautions
Please observe the following precautions to ensure the safety of the service engineer as well as
operators when servicing this equipment. For detailed information about each precaution, refer to the
main body of this manual.
CAUTION: 1. If the system transformer is installed beside the console, adequate distance
must be kept between them. Otherwise, the displayed images may be
adversely affected.
2. In general, the scanning room must be provided with an independent air
conditioning system.
Even if the room is maintained within the permissible temperature range,
gradual temperature shifts (for example, a slow increase in room
temperature from morning to evening) may adversely affect system
performance.
3. The air conditioning system in the scanning room must be installed so that
the CT system is not exposed to direct airflow. Failure to do so may cause
the temperature inside the CT system to fluctuate, possibly affecting the
displayed images adversely.
CAUTION: 1. An independent power supply must be provided for this system at the cubicle output
stage. Otherwise, this system may adversely affect other facilities or equipment.
2. Use only noise filters manufactured by Toshiba. The noise filter of this system is
designed taking into account extreme phenomena such as lightning. If a noise filter
made by a manufacturer other than Toshiba is used, the system may not be protected
adequately.
3. Although two different hardeners are available for the epoxy resin (winter-use hardener
and summer-use hardener), the winter-use hardener must be used.
The summer-use hardener is not suitable for work in hospitals or clinics because it
requires a long hardening time and, in some cases, the application of heat may be
necessary to achieve hardening.
4. Observe the following precautions when applying epoxy resin during floor-leveling work.
•Good ventilation must be provided since the epoxy resin is a volatile chemical.
•This job must be performed with a plastic floor-covering sheet laid on the floor.
•Gloves, eye protection, etc. must be worn when handling the resin.
•Before mixing the liquid agents, they must be accurately weighed using an oil
replenishment container.
•The oil replenishment container that has been used for weighing must not be used to
apply the resin.

room and the entrance.
(Refer to subsection 7.2 "X-ray Shielding in the Scanning Room".)
(3) Ceiling height
The ceiling should be 2500 mm or higher at a floor level considering that equipment such as

Since the gantry includes components such as detectors or electronic circuits which permit
high-precision measurement, air conditioning is required to maintain high precision. For
details, refer to subsection 9.1 "Air Conditioning".
(6) Illumination
Illumination should be adjustable, because it is easier to specify the desired scan slice
position using the positioning projectors when illumination is decreased.
(7) Wiring pits and ducts

5.2 Scan Control Room
The console (CPU BOX, monitors×2, keyboards×2, mice×2) is installed in the scan control room.
CAUTION: If the system transformer is installed beside the console, adequate
distance must be kept between them. Otherwise, the displayed images
may be adversely affected.
(1) Window
The window for monitoring the scanning room should be in front of or on the side of the
console. The lowest window frame should be 90 cm from the floor for easy patient
monitoring. A curtain should be provided for the window facing the outside.
(2) Entry
Doors should be provided at both the corridor and scanning room.
Take extreme care for X-ray leakage from the scanning room door.
(3) Illumination
For easy image reading, install freely adjustable or two-step-adjustable illumination.
(4) Receptacles
At least two standard outlets should be provided near the console for installation of the 3D
workstation and InnerVision PC.
A public telephone line jack for InnerVision should also be provided.
In addition to the above, the wiring and power distribution ducting or pit should be installed in

5.5 System Operating Environment and EMC
Recently, the EMC (electromagnetic compatibility) problem in hospitals has drawn attention. To
prevent the problem from occurring and to ensure that the system operates in a stable manner,
this system conforms to IEC60601-1-2, the international standards regarding EMC.
The standards specify the requirements taking into account the following points:
<1> Adverse effect on other systems due to noise generated by this system
<2> Adverse effect on this system due to noise generated by other systems
<3> Adverse effect on this system due to static electricity
In actual hospitals, not all systems meet the standards.
Systems such as laser surgical unit, microwave accelerator, microwave thermal therapy system,
etc. emit high-level electromagnetic waves due to their characteristics. This system may adversely
affect ultrasound systems which use faint signals.
With regard to static electricity, the level may easily exceed the level specified in the standards
depending on the operating environment.
Therefore, take extreme care when determining the installation location.
For example, the system should be installed at a location as far from equipment emitting strong
electromagnetic waves as possible.
There are methods for reducing mutual influence to preventive the EMC problem. Refer to
subsection A.1 "HANDLING EMC" of the appendix.
