Abstract

Ce dispositif d'examen par rayons X comportant un tube intensificateur d'image radioscopique et une chaîne de télévision est muni d'un matériau d'enregistrement d'image photographique pouvant être élaboré directement contre la fenêtre de sortie dudit tube intensificateur. De ce fait, l'optique de base entre le tube intensificateur et le tube d'enregistrement d'image de télévision ne doit pas comporter de système de division usuel basculant, ce qui permet de rendre optimale ladite optique de base pour obtenir un système compact dont la transmission des images est optimale. Du fait que l'enregistrement après la fenêtre de sortie, la quantité de rayonnement nécessaire peut être beaucoup plus petite alors qu'en même temps la quantité de matériau photographique diminue. Application à l'appareillage radiologique.This X-ray examination device comprising a fluoroscopic image intensifier tube and a television channel is provided with a photographic image recording material which can be produced directly against the exit window of said intensifier tube. Therefore, the basic optics between the intensifier tube and the television image recording tube must not include the usual tilting dividing system, which makes it possible to optimize said basic optics to obtain a compact system. whose image transmission is optimal. Since recording after the exit window, the amount of radiation required can be much smaller while at the same time the amount of photographic material decreases. Application to radiological equipment.
