摘要:
A radiation source for a radiation-based image acquisition device has an electron emitter to generate a focal spot for x-ray generation at a rotating anode. An arrangement is provided to generate an asymmetrical power input profile of the focal spot parallel to the movement direction of the rotating anode.
