Dose Group Setting

Input Voltage 100V AC: Enable or disable “AC100V power” according to the AC power used. If AC 100V power is enabled, the Dose Group will be set as Normal 50 and HLF 50 automatically. This setting will be only selected when the input voltage is 100V AC, but it is inapplicable for 110V or 120V. NOTE

The following section describes the instruction how to set Dose Group and X-ray Control according to the following Table “Exposure Management Matrix”. If the instruction contradicts the corresponding regulatory requirements of certain countries or regions (for example, some regulatory requirements are updated), change the setting according to the regulatory requirements.

Select Dose Group option by country to set the dose limitation in normal (standard) and HLF exposure. The available options are: Normal 88 and HLF 100 Normal 50 and HLF 50 Normal 50 and HLF 100 Refer to the following table “Exposure Management Matrix” to set Dose Group.

6-7


The skin dose rate in the Dose Group represents the value for conditions of free-in-air irradiation at the patient skin: 30cm along the beam axis from the image intensifier surface. 1. Two dose groups in normal (standard) fluoro mode -Normal50: The skin dose rate does not exceed 50mGy/min in standard fluoro mode, such as Australia, Japan, New Zealand, etc. -Normal88: The skin dose rate does not exceed 88mGy/min in standard fluoro mode, such as USA, , etc. 2. Two dose groups in HLF mode: -HLF50: The skin dose rate does not exceed 50 mGy/min in HLF mode, such as Japan, etc. -HLF100: The skin dose rate does not exceed 100 mGy/min in HLF mode, such as Australia, Italy, UK, New Zealand, etc. For the country, such as USA, if the skin dose rate shall not exceed 176 mGy/min in HLF mode from its regulatory requirements, the system will use HLF100 in HLF mode because the maximum skin dose rate of the X-ray tube cannot exceed 100 mGy/min. 3. For some country, its dose limitation should be the combination of the above normal and HLF groups. For example, -Australia: Normal50 and HLF100 -China: Normal88 and HLF100 4. For countries or regions that have a higher standard fluoro dose (at the patient skin) rate limit than USA, the dose limits are set to the same value as for USA. 5. For countries or regions that have a higher HLF dose (at the patient skin) rate limit than USA, the dose limits are set to the same value as for USA. 6. For countries or regions that do not specify standard fluoro dose at patient skin, the dose limits are set to the same value as for USA. 7. For countries or regions that do not specify HLF dose at patient skin, the dose limits are set to the same value as for USA. 

Periodic Maintenance


9.1.

Overview

This procedure describes how to conduct performance checks and maintenance procedures. Use the procedure in conjunction with PM checklist in section 9.2. Follow the procedures in the order they appear here and record all required information on the checklist. Serious injury and property damage can result from incorrectly performed service procedures. Observe all operating and safety procedures in this document. WARNING

9.1.1.

Procedures should be performed by service personnel specifically trained by GE Healthcare do Brasil Comércio e Serviços para Equipamentos Médico-Hospitalares LTDA to calibrate the Brivo OEC 850 C-Arm and Workstation.

Safety

Ingress of Fluids WARNING

The system must never be operated or stored in locations where conductive fluids, like water and saline solution, might spill on the equipment.

Always unplug the AC power cable from the wall outlet before cleaning the equipment. Do not allow water, soap, or other liquids to drip into the equipment and cause short circuits, electric shock and fire hazards. Unauthorized Modifications Under no circumstances should the safety interlock in the system be byed, jumped, or otherwise disabled.

NOTE

All GE Healthcare systems comply with International Electro Technical Commission safety standard IEC-60601. Do not connect any external device to the system that does not meet the requirements of IEC 60601-1:1995. Only devices provided or approved by GE Healthcare do Brasil Comércio e Serviços para Equipamentos Médico-Hospitalares LTDA should be connected to the system.

Motorized Mechanical Operation The Vertical Column is motorized and should be observed continuously during operation to avoid pinching or colliding with people and object. If covers are removed, use extreme care when operating motorized features. Do not carelessly place objects on the equipment or bump or lean against the equipment. Do not wear loose clothing that may be caught by mechanical mechanisms. Keep hands and fingers clear of motorized equipment while the motors are in operation.

9-2


Electrical Shock WARNING

WARNING

This system can generate lethal voltages. Practice safe electrical testing procedures when performing periodic maintenance procedures. After taking X-rays, the high voltage cables can retain a lethal charge, even if you power down the system. Even though the s are recessed, high voltages can arc several inches from their terminals if the cables are removed from the connector wells. Take care when disconnecting high voltage cables even when the power is turned off. If you remove these connections, immediately discharge their s against the high voltage tank case (ground).

X-radiation Exposure The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray shielding in place. Use lead shielding and draping to protect personnel. WARNING

CAUTION

Lead aprons, radiation monitors, and appropriate radiation shields must be utilized for the protection of all personnel in the vicinity while performing tests. Living human anatomy should never be used as a phantom or demonstration aid. Do not produce radiation in hallways. Many of the PCB's in this system contain components, which are sensitive to ElectroStatic Discharge (ESD). Observe ESD safety procedures.
