Abstract
The invention relates to a radiological image intensifier tube with a video output. The tube has in the same vacuum envelope an image section and an analysis section having a common face occupied by target. An electrical image corresponding to the incident X-ray image is formed in the image section and this image is read in the analysis section by an electron beam scanning the target point by point. This target has in the tubes according to the invention a structure making it possible to limit the X photon-video signal gain and to regulate it between two predetermined values. On its face which receives the photoelectrons e.sup.31 it has a metal barrier layer 1 covering a luminescent layer 2, in contact with a semitransparent layer 3 covering the actual target 4.
