Characteristics of electro-optical X-ray image intensifiers for medical electrical equipment. - Determination of the detective quantum efficiency Ingestion-build-209418 Test methods are also included1 Scope This International Standard applies to electro optical X ray image intensifier for medical use, as components of diagnostic X ray equipment. This International Standard describes a method of determining the detective quantum efficiency (DQE) of X ray image intensifiers by analysis of the single gamma ray photon scintillation pulse height spectrum. The method of this standard applies only to electro optical X ray image intensifiers having
