Abstract
An exemplary embodiment includes an x-ray generator, an x-ray tube, and an x-ray image intensifier television chain, which comprises an x-ray image intensifier, an optical coupling member, a television pick-up tube of the vidicon type, a video amplifier, a regulating installation for the illumination level of the television pick-up tube, a control device for the control of the functional sequences and for the generation of the synchronous clock pulse frequencies, a deflection and focusing unit, and a video monitor. The control device is so designed that through the latter the regulating installation is capable of being switched over to a higher setpoint value; the deflection and focusing unit, to an operation for scanning with reduced frequency; and the x-ray generator to pulse operation with an increased dose rate.
