Figure 1-1: Required work space (mm (inch)) Be sure to leave sufficient room to maneuver the G-Arm, and take the required work space into consideration.

  • Page 17: General Protection

    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.
  • Page 18 Chapter 1 - Overview and Safety Radiation Protection 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 cover of the hole where the X-ray is emitted is the nearest position to the X-ray source that the patient body can reach during normal use, which me- chanically preserves the minimum SSD.

    Acronyms and Abbreviations Chapter 1 - Overview and Safety 1.9.6 Penetration of Fluids The G-Arm system is not waterproof. If liquids drip into the equipment, disconnect the power cord. Do NOT operate the system until it has DANGER been cleaned and inspected by a qualified service engineer. Excessive amount of fluids such as antiseptics, cleaning solutions or body fluids may damage the internal components if seeped through.
