A panel shaped, proximity type, multi-stage x-ray image intensifier tube for medical x-ray diagnostic use having all linear components and yet a high brightness gain, the tube being comprised of a rugged metallic tube envelope, an inwardly concave , metallic input window, a full size output display screen, a planar, activated alkali-halide scintillator photocathode screen, a fiberoptic plate between the scintillator-photocathode screen and the output display screen, the plate having an intermediate display screen on one flat side facing the scintillatorphotocathode screen and a second photocathode on the otherside, which faces the output display screen, and with the scintillatorphotocathode screen and the fiberoptic plate being suspended on insulators within the envelope and in between the input window and the output screen. Separate, high, negative electrostatic potentials are applied between the scintillator-photocathode screen and the intermediate display screen and between the second photocathode and the output display screen. The tube can be used in a direct view, photofluorographic mode, in a radiographic camera system and with a remote view T.V. System.
