X-ray equipment with an X-ray generator and an X-ray tube with at least two electron sources

摘要

The invention relates to an X-ray generator for supplying an X-ray tube (1) which has at least two electron sources (11, 12) for producing a focus spot of different size at the same point on the anode in each case. In this case, the resolution capability can be matched to the respective requirements by allocating in each case one control unit (21, 22) to each electron source, which control unit produces a current (which is dependent on a control signal at a control input of the control unit) between the associated electron source and the anode (10), by both control units acting while an X-ray photograph is being taken, and by the control signals, and hence the ratio between the mAs products supplied by the electron sources, being adjustable.
