X-ray tube having scintillator-photocathode segments aligned with phosphor segments of its display screen

Patent ·
OSTI ID:5478643
An x-ray amplifier tube of the proximity design in which the scintillator screen, the photo-cathode screen and the output phosphor display screen are all segmented, with the segmentations of each screen being in registry with those of the other screens. In some embodiments one or more apertured masks are interposed between the scintillator-photocathode screen assembly and the output phosphor display screen, or ahead of the scintillatorphotocathode screen assembly, the apertures of the masks being in registry with the segmentations of the scintillator-photocathode screen and the output phosphor display screen.
