Medical electrical equipment - Characteristics of electro-optical X-ray image intensifiers - Part 6: Determination of the contrast ratio and veiling glare index (IEC 61262-6:1994); German version EN 61262-6:1994
An X-ray intensifier reduces the irradiation of the patient. It is a significant part of the image system. The test procedures for the contrast ratio and veiling glare index enable manufacturers and test houses to increase the image quality.
