ABSTRACT:
A method and circuit arrangement for improving the definition of the focal spots of X-ray tubes which comprises periodically varying the bias voltage applied to the concentrating electrode of the tube, focalizing the eletron beam emitted by the filament, between a negative minimum or zero value and a negative maximum value, with a voltage waveform whose frequency is higher than 10 kilohertz, wherein this bias voltage has to assume at least the two extreme values frequently, while a direct-current high voltage is being applied between the cathode (filament) and the anode (target) during the exposure time.
