Radiation Protection

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

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

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

The G-Arm system triggers a warning alarm when 5 minutes of fluoroscopic

imaging time is accumulated during a single study.

The X-ray radiation value varies in proportion to the product of the kV value

and mA value.
