X-ray sources
First Claim
1. An anode for an X-ray tube comprising a first part and a second part, wherein the first part and second part, in combination, form more than one aperture, wherein at least one of said apertures comprises an electron aperture through which electrons emitted from an electron source travel subject to substantially no electrical field, a target in a non-parallel relationship to said electron aperture and arranged to produce X-rays when electrons are incident upon said target, and wherein at least one of said apertures comprises an X-ray aperture through which the X-rays from the target pass through and are at least partially collimated by the X-ray aperture.

Abstract
An anode for an X-ray source is formed in two parts, a main part (18) and a collimating part (22). The main part (18) has the target region (20) formed on it. The two parts between them define an electron aperture (36) through which electrons pass reach the target region (20), and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced.

11. An X-ray tube comprising:
- an anode further comprising a first part and a second part, wherein the first part and the second part, in combination, form more than one aperture, wherein at least one of said apertures comprises an electron aperture through which electrons emitted from an electron source travel subject to substantially no electrical field, a target in a non-parallel relationship to said electron aperture and arranged to produce X-rays when electrons are incident upon said target, and wherein at least one of said apertures comprises an X-ray aperture through which the X-rays from the target pass through and are at least partially collimated by the X-ray aperture and an electron source.
