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

摘要

An x-ray system which can be operated at various energy supply sources which can respectively deliver different average electric powers per unit of time, has an x-ray source supplied by a voltage generator, an x-ray receiver and a control unit to which the average electrical power to be drawn from the respective energy supply source can be prescribed. The control unit actuates the voltage generator so that, given the prescribed available average electrical power per unit of time, x-ray pulses can be generated with a period, an x-ray energy and a pulse repetition rate so that x-ray images of moving objects can be acquired in cine mode, with the average electrical power per unit of time drawn from the respective energy supply source not being exceeded, and with at least the x-ray energy or the pulse period or the pulse repetition rate of the x-ray pulse to be generated being prescribed.
