Abstract

An x-ray tube assembly includes an x-ray tube with a vacuum envelope in which an emitter and an anode are arranged. The emitter is configured to be heated by an external coil emitter heating current supply. The emitter is configured as a flat emitter and an adaptation circuit is arranged between the flat emitter and the coil emitter heating current supply. A coil-emitter-based x-ray tube assembly may be replaced by a flat emitter-based x-ray tube assembly without constructional changes.
