<p>A film feeding mechanism for use during medical x-ray techniques, particularly angiography. Sheets of film (46) are fed sequentially at high speed into a film exposure device (34), in a manner so as to reduce damage to the films, including the build-up and discharge of static charge on the films. In the film exposure device (34), a free-floating lower clamping assembly (144) clamps each film (46) from the center of the film progressively outward towards its leading and trailing ends, to eliminate wrinkling of the film.</p> |
