Abstract
An x-ray anode for an x-ray emitter has a structured surface provided for impingement with electrons. According to an embodiment of the invention, the structured surface has a surface structure which alternates periodically at least in sections and which varies in the micrometer range with respect to its depth extension and periodicity.

An x-ray anode for an x-ray emitter, the x-ray anode comprising:
- a structured surface provided for impingement with electrons, the structured surface including a surface structure that periodically alternates at least in sections and that has a varying depth extension, wherein
- the varying depth extension and a periodicity of the surface structure are up to 40 μm.
A method, comprising:
- using an x-ray emitter to generate x-ray images, the x-ray emitter including an x-ray anode, the x-ray anode having a structured surface provided for impingement with electrons, the structured surface including a surface structure that periodically alternates at least in sections and that has a varying depth extension, wherein
- the varying depth extension and a periodicity of the surface structure are up to 40 μm.
A method for producing an x-ray anode including a structured surface provided for impingement with electrons, the structured surface including a surface structure that periodically alternates at least in sections and that has a varying depth extension, wherein the varying depth extension and a periodicity of the surface structure are up to 40 μm, the method comprising:
- introducing the surface structure into the material of the x-ray anode via an ablation method or via an additive manufacturing method.
