Chapter 1 - Overview and Safety Required Work Space
16 B6 User Manual
1.8 Required Work Space
Figure 1-1 (p16) demonstrate the work space required for the operator to op-
erate the G-Arm system in any particular area.
1.9 Radiation Protection
X-ray radiation exposure can be harmful to the human body.The cumulative
effect it creates may last for months or years. Operators and service person-
nel should avoid direct exposure to the X-ray beam and take protective mea-
sures to avoid scattered radiation.
No design can guarantee absolute safety or complete protection for those
who fail to take adequate safety precautions. Only properly trained opera-
tors or authorized service personnel are allowed to operate this unit. Both
the operators and service personnel should be aware of the risk of X-ray ra-
diation during routine operation and the risk of high-voltage electric shock
during equipment maintenance.
Figure 1-1: Required work space (mm (inch))
CAUTION
Be sure to leave sufficient room to maneuver the G-Arm, and take the
required work space into consideration.

XGB6-12-1014, Rev 1.04 17
Radiation Protection Chapter 1 - Overview and Safety
1.9.1 General Protection
The owner of the G-Arm system must designate areas suitable for safe oper-
ations and maintenance of the equipment and ensure the G-Arm system are
only used in those areas. For example, allocate a room exclusively to the
equipment, where protective precautions like lead shields and lead screens
are provided to separate the X-ray radiation field from the human bodies ir-
relevant to the purpose of the clinical procedure.
While using the equipment, the owner must ensure that all personnel wear
radiation monitoring devices (operator dosimeter) and appropriate protec-
tive clothing, helmet, apron, goggles, shield, etc.
Remain alert for visual indicators and audible alarms that are activated when
ionizing radiation is being generated by the equipment in the work area.
Additionally, the G-Arm system uses grids to reduce the amount of scattered
radiation.
1.9.2 Keeping Distance
Maintaining a safe distance from the source is another effective protective
method. Locations more than 2 meters away from the X-ray focus is consid-
ered to be safe when equipped with protective devices and protective cloth-
ing.
1.9.3 Reducing Dosage
The collimator are carefully configured so that it regulates itself more pre-
cisely upon SID changes. Better precision in collimator movements boosts
the image quality and minimizes the dosage, and greatly reduces the
amount of scattered radiation.
1.9.4 Exposure Alert
The G-Arm system triggers a warning alarm when 5 minutes of fluoroscopic
imaging time is accumulated during a single study.

●"Exposure Lamps and Audible Signals" (s3.6, p41)
1.9.5 Source-to-skin Distance
The X-ray radiation value varies in proportion to the product of the kV value
and mA value.

Chapter 1 - Overview and Safety Radiation Protection
18 B6 User Manual
International regulations specify that a minimum source-skin distance (SSD)
of 300 mm shall be maintained. However, for specific surgical applications, a
minimum SSD of 200 mm is required.
The coverof the hole where the X-ray is emitted is the nearestposition to the
X-ray source that the patient body can reach during normal use, which me-
chanically preserves the minimum SSD.
The G-Arm system may come with an optional accessory - skin spacer - to
create additional space between the focal spot and the patient body. The
minimum SSDs that the G-Arm system can reach, with or without the skin
spacer installed, are illustrated as in the figure below:
In normal conditions, the SSD shall be far enough to keep the dosage as low
as possible.
Figure 1-2: Minimum Source-skin Distance (SSD)
1 SSD w/ Skin Spacer 2 SSD w/o Skin Spacer
3 Skin Spacer 4 Focal spot
DANGER
Exposing the eyes or the skin to the primary X-ray beam may result in
severe radiation burns in the event of repetitive or prolonged expo-
sures. The hazards are most often associated with exposure to X-ray
radiation including increased risks of cancer and genetic effects in
exposed populations.
