Abstract: 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.

Abstract: An apparatus has an arrangement for the transmission, via conductors, of electrical energy and/or signals from an apparatus part to electrical devices which are displaceable relative to the apparatus part. The arrangement has a rotatable reel onto which another conductor is wound when one conductor is unwound.

Abstract: An X-ray exposure apparatus has an X-ray exposure system that rotates during an image exposure wherein sharp images are generated despite the motion employs a digital filtering of the image information ensues taking the exposure time and the motion of the X-ray exposure system into consideration, thereby eliminating motion artifacts.

Abstract: X-ray apparatus with a ceiling suspension has a motor for displacing and positioning the X-ray apparatus and a motion control circuit which superimposes a dynamic motion factor on the motor output so that pendulum motions during an acceleration of the apparatus are counteracted. For this purpose, a filter is connected in the motion control circuit in front of the setting element of the motor, the filter being dimensioned so as to correspond to the characteristic system behavior, and compensates oscillations of the apparatus.
