fluoroscopic screen

Thus electrokymography and roentgenkymography were among the early ways to record images from a simple fluoroscopic screen.

Edison provided Pupin with a calcium tungstate fluoroscopic screen which, when placed in front of the film, shortened the exposure time by twenty times, from one hour to a few minutes.

This was often done either by filming a simple fluoroscopic screen with a movie camera (variously called fluorography, cinefluorography, photofluorography, or fluororadiography) or by taking serial radiographs rapidly to serve as the frames in a movie (cineradiography).
