Abstract
The present invention is directed to an anode for an X-ray tube. The X-ray tube has an electron aperture through which electrons emitted from an electron source travel subject to substantially no electrical field and a target in a non-parallel relationship to the electron aperture and arranged to produce X-rays when electrons are incident upon a first side of the target, wherein the target further comprises a cooling channel located on a second side of the target. The cooling channel comprises a conduit having coolant contained therein. The coolant is at least one of water, oil, or refrigerant.
Claims20
An anode for an X-ray tube comprising
- a. an electron aperture for receiving electrons emitted from an electron source travel;
- b. a target in a non-parallel relationship to said electron aperture and arranged to produce X-rays when electrons are incident upon a first side of said target, wherein said target further comprises a cooling channel located on a second side of said target;
- and
- c. a channel extending from said electron aperture to said target wherein electrons passing through said channel are subjected to substantially no electrical field.
An X-ray tube comprising:
- an anode further comprising at least one electron aperture for receiving electrons emitted from an electron source, a target in a non-parallel relationship to said electron aperture and arranged to produce X-rays when electrons are incident upon a first side of said target, wherein said target further comprises a cooling channel located on a second side of said target, a channel extending from said electron aperture to said target wherein electrons passing through said channel are subjected to substantially no electrical field, and at least one of aperture comprising 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.
