ABSTRACT:
The invention relates to a circuit arrangement useful in an X-ray diagnostic apparatus for supervising the loading of an X-ray tube. A first signal which is dependent on the anode temperature controls an indication and/or a blocking device. A second signal is formed which corresponds to the maximum temperature (T.sub.max) minus a value (.DELTA. T) which is dependent on the exposure load to be expected. The two signals are compared with each other and the indication or blocking device is released if the temperature (T.sub.i) represented by the first signal is lower than the temperature (T.sub.max -.DELTA. T) represented by the second signal.
