X-ray apparatus operable at different energy supply sources which respectively deliver different average electrical powers per unit of time

An x-ray apparatus operable at a plurality of different energy supply sources which respectively deliver different average electrical powers per unit of time, said x-ray apparatus comprising:

• an x-ray source which emits a pulsed x-ray beam composed of a plurality of x-ray pulses;
• an x-ray receiver on which said x-ray pulses are incident;
• a voltage generator adapted for connection to a plurality of different energy supply sources which respectively deliver different average electrical powers per unit of time, said voltage generator being connected to said x-ray source for supplying operating voltages to said x-ray source;
• and
• control means connected to said voltage generator for actuating said voltage generator dependent on the available average electric power per unit of time of an energy supply source currently connected to said voltage generator, for causing said x-ray source to emit x-ray pulses having a period, an x-ray energy and a repetition rate for obtaining x-ray images of moving objects in a cine mode without exceeding an average electrical power available from the energy supply source currently connected to said voltage generator;
• and
• means for prescribing at least said available average electric power per unit of time from a supply source currently connected to said voltage generator, and for prescribing at least one of said x-ray energy, said pulse period and said pulse repetition rate to said control means.
