Abstract: The X-ray tube having a rotating and linearly translating anode includes an evacuated shell having a substantially cylindrical anode rotatably mounted therein. The substantially cylindrical anode may be rotated through the usage of any suitable rotational drive, and the substantially cylindrical anode is further selectively and controllably linearly translatable about the rotating longitudinal axis thereof. A cathode is further mounted within the evacuated shell for producing an electron beam that impinges on an outer surface of the substantially cylindrical anode, thus forming a focal spot thereon. X-rays are generated from the focal spot and are transmitted through an X-ray permeable window formed in the evacuated shell.

Abstract: The present invention relates to an X-ray tube in which X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. The anode has a straight main body and a protruding portion, extending along an axis line direction of the main body from a tip of the main body. An inclined surface, onto which the electrons emitted from the electron gun collide, and a pair of side surfaces, disposed in parallel while sandwiching the inclined surface, are formed on the protruding portion. A distance between the pair of side surfaces of the protruding portion is shorter than a width of the main body in the same direction as the distance.

The electron beam scanner also includes a target arranged concentric with the detector and located opposite the detector across the scan field, the target having end portions circumferentially overlapping the detector and radially aligned with the gap between the detector rings, such that when the electron beam impinges on the target the target transmits radiation through the gap across the scan field to an associated section of the detector.

Abstract: An x-ray computed tomography apparatus has one anode ring in a vacuum housing surrounding an examination volume, wherein a focus of an x-ray source revolves on the anode ring to expose the examination volume with an x-ray beam from different directions, and a detector system arranged on a rotating frame that can rotate around a system axis. The detector system serves to detect the x-ray radiation exiting from the examination volume, wherein the detector system and the focus can rotate around the system axis synchronously and in the same rotation direction with a rotation angle offset by 180°. The apparatus also includes a computer to process the measurement values acquired by the detector system. The anode ring can be driven such that it rotates around the system axis, and the rotation direction of the anode ring and the rotation direction of the focus around the system axis are opposite while a rotation of the focus around the system axis ensues.
