The patient should be positioned as far away from the X-ray source as possible in order to keep the absorbed dose to the patient as low as reasonably achievable.
CAUTION
Additional objects in the beam, such as tables and patient supports, may cause the imaging system to increase the amount of radiation, in order to obtain an optimal image. Prevent additional exposure by removing unnecessary objects from the path of the beam.
1.4.2 Ingress of fluids WARNING: The X-ray system is not rated for water-tight operation. If liquids drip into the equipment, disconnect the power cord and do not operate the system until it can be cleaned and inspected by a qualified service engineer. Excessive amounts of fluids such as antiseptics, cleaning solutions or bodily fluids may damage internal components if they are allowed inside the equipment. Use drapes, if necessary, to protect equipment when performing procedures and do not apply excessive amounts of fluid when cleaning.
1.4.3 Cooling efficiency Draping some parts of the X-ray equipment may restrict airflow to components that provide heat sinking and to vents designed to cool the equipment. Drape equipment and cover vents only when exposure to excessive fluids is unavoidable and extended use of the equipment is not required.
1.4.4 Burns WARNING: Extended use of imaging equipment may cause components such as X-ray tubes to reach temperatures capable of inflicting burns. Use care when positioning equipment to avoid placing hot components in close proximity to patients and personnel. An anesthetized or unconscious patient is incapable of sensing and reacting to a hot component.
1.4.5 Performance criteria The system is designed to perform its intended function during normal operation. In the presence of electromagnetic interference some degradation of displayed live video may occur but the system will return to normal operation when the interference is eliminated. Any loss of function will be readily apparent to the operator and will not cause a safety hazard. Electromagnetic interference will not cause permanent damage to the system.
