Abstract (en)
[origin: US4960987A] An x-ray image intensifier for use in an x-ray diagnostic system has an electrode system for focusing electrons generated by incident x-radiation on an input luminescent screen onto an output luminescent screen. For reducing manufacturing and assembly costs, the electrodes of the electrode system are applied as a coat on the inside of a one-piece sheet metal part which forms the wall of the x-ray image intensifier between the input and output luminescent screens. The coat is adapted in shape as needed to form the electrodes, and the sheet metal wall, with the electrodes thereon, has different diameters along its longitudinal length matched to the required electrode diameters.
