ABSTRACT:
A panel shaped, proximity type, x-ray image intensifier tube for medical x-ray diagnostic use having all linear components and yet a high brightness gain, in the range of 500 to 20,000 cd-sec/m.sup.2 -R, the tube being comprised of a rugged metallic tube envelope, an inwardly concave, iron, nickel, chromium alloy input window, a full size output display screen, a halide activated alkaline-halide scintillator photocathode screen suspended on insulators within the envelope and in between the input window and the output screen, and a high Z glass output window to reduce x-ray backscatter inside and outside of the tube. The tube can be used in a direct view, photofluorographic mode, in a radiographic camera system and with a remote view T.V. system.
