A method, in an embodiment, is for setting an X-ray intensity using a structured anode or a field emitter cathode or a finger-shaped cathode head. Other embodiments include an associated X-ray device, an associated single X-ray tube CT scanner, an associated dual X-ray tube CT scanner, and an associated computer program product.

Dose modulation

A cathode has a cathode head in which is arranged at least one emitter that emits electrons upon application of a heating voltage. At least one series resistor is connected in the voltage feed to at least one emitter. The use of such a cathode in an x-ray tube enables x-ray exposures with a high quality.
