Abstract
An X-ray source device includes a cathode arrangement including a cathode device arranged to emit an electron beam therefrom. An anode arrangement includes an anode spaced apart from the cathode device at a focal distance and arranged to receive the electron beam from the cathode device at one of a plurality of focal spots thereon. The anode is movable such that each of the focal spots is alignable to receive the electron beam, in some instances while maintaining the focal distance of the anode from the cathode device. An associated method of forming an X-ray source device is also provided.

An X-ray source device, comprising:
- a cathode arrangement including a cathode device arranged to emit an electron beam therefrom;
- and
- an anode arrangement including an anode spaced apart from the cathode device at a focal distance thereof and arranged to receive the electron beam from the cathode device at one of a plurality of focal spots thereon, the anode being movable such that each of the focal spots is alignable to receive the electron beam.
A method of forming an X-ray source device, comprising:
- arranging an anode of an anode arrangement in spaced apart relation from a cathode device of a cathode arrangement and at a focal distance thereof, such that the anode receives an electron beam emitted from the cathode device at one of a plurality of focal spots thereon;
- and
- arranging the anode to be movable such that each of the focal spots is alignable to receive the electron beam.
