Qualities of Fluoroscopic Screens Radiographic Films and Intensifying Screens

Abstract

In fluoroscopy or, “screening” as it is also called, the X-ray image is immediately converted into a visual image on a fluorescent screen. As opposed to radiographic methods, fluoroscopy is a process that extends over a relatively long period of time, usually several minutes, and it therefore entails the risk of exposing the patient to an impermissible dose of radiation. To reduce this risk to a minimum, the luminous efficiency of the fluorescent screen (fluoroscopy screen) must be as high as possible, that is to say it must convert the maximum amount of X-rays into visible light.
