[Effect of voltage errors of an x-ray diagnostic apparatus on the quality of the x-ray image].

The technical suitability of key assemblies in the roentgen unit and the quality of X-ray examinations depend upon a proper choice of permissible voltage setting errors in the X-ray tube. To determine the permissible voltage setting errors in the roentgen apparatus a criterion for the required accuracy of such settings has been suggested and the voltage error in Soviet-made units operating in medical establishments assessed experimentally.
