  • Page 20: Manufacturer's Responsibility

    Phantom Installation, Operation & Service Manual Manufacturer’s Responsibility Although this equipment incorporates protection against X-ray radiation other than the useful beam, practical design does not provide complete protection. Equipment design does not compel the operator or assistants to take the necessary precautions; nor does it prevent the possibility of improper use (authorized or unauthorized persons carelessly, unwisely, or unknowingly exposing themselves or others to direct or secondary radiation).

  • Page 21: Radiation Protection Survey

    Phantom Installation, Operation & Service Manual A common method of determining whether personnel have been exposed to excessive radiation is the use of film badges. These are X-ray sensitive film enclosed in a badge that incorporates metal filters of varying degrees of transparency to X-ray radiation.

    Phantom Installation, Operation & Service Manual 7.4 Technical Theory of Operation 7.4.1 System Overview The Phantom incorporates three major electrical sub-assemblies. The Generator Assembly consists of the high voltage circuitry, the x-ray tube and the collimator (further discussed in section 7.4.2). The Control Assembly houses all of the electronics, microprocessor, high frequency generating circuits and the front panel controls (further discussed in section 7.4.3).
