Pulsate X-ray generating apparatus |
摘要 |
A capacitor connected between the anode and cathode of an X-ray tube through an X-ray switch is charged by a DC output voltage including ripple component from a rectifier connected to the secondary of a high-tension transformer. The primary of the high-tension transformer is connected to a switching circuit. A switching control circuit produces a turn-on signal for the switching circuit when a pulse signal derived from a phase detector in synchronism with a given phase of the ripple component, an X-ray exposure instruction signal and a charge instruction signal formed in a comparator are logically processed, and a turn-off signal when the charge voltage of the capacitor reaches a given value. The switching circuit is ON-OFF controlled by the switching control circuit.
