The entrance field size of the electro-optical X-ray image intensifier can be specified in several ways depending on the specific SED. Typically, the entrance field size is specified as a nominal entrance field size or as a useful entrance field size. The source to entrance plane distance (SED) for the nominal entrance field size is infinite, while the useful entrance field size is measured at a specific SED, usually one meter. Both the nominal entrance field size and the useful entrance field size are considered in this standard. The nominal entrance field size is calculated from several useful entrance field size measurements. Measurements of the useful entrance field size in the magnification modes of the electro-optical X-ray image intensifier will also be considered. 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 entrance field size of X-ray image intensifiers.
