Television X-Ray Movies: Dose and Contrast Factors

A television link with nonlinear circuits aids X-ray movie production by allowing concentration on a small brightness range, and dose can be determined by the detail to be observed rather than by film properties. A continuously-moving-film camera viewing a single line on the kinescope, or a video tape recorder, need lose the effect of no interacting quantum. The frame rate aspect is considered and a systematic exposure procedure is given. An X-ray beam monitor is also described. The probable course of certain future developments is given as well as suggestions for the best use of existing detectors.
