    Abstract: The x-ray target assemblies have an oxide dispersion strengthened (ODS) refractory metal alloy substrate that is bonded to a carbon-containing heat sink. The x-ray target assemblies have excellent bonding between the substrate and the heat sink. The improved bonding is achieved by placing an oxide-free barrier layer between the ODS metal substrate and the heat sink. The oxide-free barrier layer minimizes or eliminates chemical reactions that would otherwise be possible between the dispersed oxides and the carbon-based heat sink during the manufacturing process. Preventing these undesired reactions while manufacturing the x-ray target assembly yields a device with improved bonding between the heat sink and the substrate, compared to devices manufactured without the barrier layer.

    Abstract: The present invention refers to X-ray tubes of the rotary-anode type for generating a fan beam of X-rays. More particularly, the invention is concerned with a system and method for compensating a class of system-related disturbances of the focal spot position FS on a target area AT of the rotating anode RA and particularly for compensating the anode wobble in an X-ray tube XT of the aforementioned type, which occurs as a periodically wobbling inclination angle of the anode disk's rotational plane with respect to an ideal rotational plane (z=0) which is oriented normal to the rotational axis z of the rotary shaft S on which the anode disk RA is inclinedly mounted due to an inaccuracy during its production process. For this purpose, the electron beam generated by a thermoionic or other type of electron emitter of the tube's cathode C and thus the focal spot position FS on a target area AT of the anode disk's X-ray generating surface (anode target) are steered such that the focal spot FS stays within the plane PCXB of the central X-ray fan beam CXB.

    Abstract: A rotating anticathode X-ray generating apparatus which is configured such that an X-ray is generated by an irradiation of an electron beam emitted from a cathode includes a rotating anticathode with an electron beam irradiating portion to generate the X-ray through the irradiation of the electron beam so that a direction of the electron beam is set equal to a direction of a centrifugal force caused by a rotation of the rotating anticathode; and a film for covering at least the electron beam irradiating portion so as to prevent an evaporation of a material making the rotating anticathode.

    Abstract: A multiple focal spot X-ray tube (100) comprising an electron source (105), which is adapted to generate an electron beam (106), an anode (110), which is arranged within the electron beam (106) and which comprises a first focal spot portion (120) and a second focal spot portion (130), whereby the second focal spot portion (130) is spatially separated from the first focal spot portion (120). The X-ray tube (100) further comprises a first electron beam manipulation unit (125), which is adapted to interact with the electron beam (106), when the electron beam (106) impinges onto the first focal spot portion (120), and a second electron beam manipulation unit (135), which is adapted to interact with the electron beam (106), when the electron beam (106) impinges onto the second focal spot portion (130). By assigning one electron beam manipulation unit (125, 135) to each of the focal spot portions (120, 130), a precise focusing of the X-ray beam can be realized individually for each focal spot of the X-ray tube (100). Preferably, the first and the second focal spot portions have a distance along the axis of a rotating anode.

    Abstract: An x-ray tube target and method of repairing a damaged x-ray tube target. The x-ray tube target includes an original substrate and a portion of the original substrate that includes a new portion of a substrate and a new target track that is attached to a void in the original substrate. The method includes removal and replacement of damaged materials on used anode targets of x-ray tubes, thereby enabling recovery of used anode targets without the use of expensive and time consuming layer deposition methods. The method also avoids the high costs and long development cycles associated with known repair and refabrication methods for anode targets of x-ray tubes.
