Claims25
An x-ray target assembly for generating x-rays comprising:
- a target substrate;
- and
- an emissive coating applied to a portion of the target substrate, the emissive coating comprising one or more of a carbide and one or more of a carbonitride.
A method of fabricating an x-ray tube target assembly comprising:
- forming a target substrate that includes Mo and alloys there of;
- and
- forming an emissive coating on the substrate, wherein the emissive coating includes one or more of a carbide and one or more of a carbonitride.
An imaging system comprising:
- an x-ray detector;
- and
- an x-ray emission source having:
- a cathode;
