Abstract: An X-ray diagnosing device for producing X-ray photographic series, particularly motion pictures, has means for overload protection of the X-ray tube and an indicating device for the permissible scene duration. The invention is particularly characterized by a calculator which is programmed corresponding to anticipated photographing programs, and which produces upon the indicating device the duration of a scene, and indication zero for the pause required for the full scene duration after the last photographing series corresponding to the selected photographing program, and, after the termination of this pause, an indication of the full scene duration.

Abstract: An X-ray diagnosis apparatus for fluoroscopy and exposure includes an image-intensifier-television chain, a device for controlling the dose rate during X-raying, means fixing the exposure data from X-raying data and an automatic exposure timer. The invention is particularly characterized by the provision of a function generator which receives a signal corresponding to the X-raying voltage and produces therefrom an output signal operating the setting means for the exposure voltage, and wherein is programmed the shape of the photographing voltage depending upon the X-raying voltage.

Abstract: An X-ray diagnostic apparatus employed in radioscopy and for X-ray film exposures, including an X-ray tube with a rotating anode, in which the transitional time during changes in operational mode is completely eliminated. A circuit arrangement is included in the X-ray diagnostic apparatus in which each exposure upon actuation of an exposure triggering element immediately follows the preceding radioscopic operation, and wherein a signal corresponding to the actual value of the anode rotational speed is transmitted to a power output adjusting element, the power adjusting element being programmed in conformance with the permissible cycle of the X-ray tube power output in dependence upon the anode rotational speed, and to thereby effect the setting of the X-ray tube power output associated with the respective anode rotational speed.

Abstract: An X-ray generator for an apparatus for the production of tomographic X-ray pictures at varying exposure periods, which is preset through the apparatus motion path of the exposure unit consisting of an X-ray tube and picture target carrier, and which includes setting means for adjusting the X-ray tube voltage and the X-ray tube current and a timing switch for determination of the exposure time. Programmed into the generator is a pair of values from the X-ray tube voltage and X-ray tube current for each exposure time and for each body organ which is to be X-rayed selectable by means of a selector arrangement, as well as including means for the selection of the path of motion.
