Characteristics of electro-optical X-ray image intensifiers for medical electrical equipment - Determination of the conversion factor1 Scope This International Standard applies to electro optical X ray image intensifiers for medical use, as components of diagnostic X ray equipment. This International Standard describes a method of determining the conversion factor of X ray image intensifiers. It is applicable only to devices whose output light spectra do not significantly deviate from that of a P 20 phosphor.
