Abstract
A combined X-ray fluoroscopy and radiography device includes an X-ray image-intensifier 4, video apparatus 24, 26, means for disposing a photographic film 27, dispensed from feed-spool chamber 28 to take-up chamber 29, in the optical path directly adjacent the intensifier output screen 14, and a ring 30 urging the film against the intensifier exit window during an exposure. The exit window comprises a fibre optic plate 6. To prevent damage, a replaceable fibre optic plate 15 is applied thereto. Exposure is sensed optically via the film, and exposure or video input intensity is adjusted by controlling intensifier gain, e.g. by varying the intensifier accelerating voltage in conjunction with a metal film covering the fluorescent screen 14, whose electron permeability varies by 1:10 for a 1:2 accelerating voltage change. Auxiliary optical means project identification symbols onto the film 27 and/or camera 24. The film image can be secured in a window in an indexed card of an addressable indexed-card information storage and retrieval system for addressable retrieval and automatic projection. <IMAGE>
