Indirect x=ray picture production - using motorised aperture synchronised to deviation coil equipped large picture tube amplifier

摘要

Indirect X-ray diagnostic picture production equipment with a large area picture tube amplifier designed for higher resolution. The X-ray tube (1) is driven from a high voltage generator (2). An aperture control (3) is placed in the primary beam in front of the patient (4). The beam traversing the patient is received in the picture amplifier (5) which has magnetic deviation coils (6) to focus the entire received beam on the output grid (7). Optical conversion (8) takes place for the TV camera (9) to pick up the signal amplify (10) it, store it (11) and display it on a TV monitor (12). The feature is the motor driven aperture (3), synchronised with the scanning and control of the deviation coils (6) in the picture tube amplifiers (5,7) so that each individual picture following in sequence receives amplification and no unnecessary X-ray transmission takes place.
