    Abstract: A method and an apparatus for locally applying material to the surface of an anode of an X-ray source as well as a corresponding anode is presented. Anode material such as a repair material for filling a recess (121) in an X-ray emitting surface (115) is applied to the X-ray emitting surface of an anode (101). The location where such material is to be applied may be detected using a laser beam (133). The applied repair material including particles (41) of anode material such as tungsten, rhenium or molybdenum, is subsequently locally sintered using a high-energy laser beam (151). The sintered material may then be melted using a high-energy electron beam (163). Using such method, a damaged surface of an anode may be locally repaired. Alternatively, structures of different anode materials or of protrusions having different levels can be provided on the X-ray emitting surface (115) in order to selectively manipulate the X-ray emitting characteristics of the anode (101).

    Abstract: A soft x-ray generator includes a unique pulse trigger assembly which reliably and reproducibly provides a plasma to initiate the discharge between a cathode and an anode, and having a cone-shaped geometry. The soft x-ray generator of the present invention also includes a rotating anode which is generally disk-shaped with an outer circumferential edge which can be rotated with respect to the cathode to expose different sections of the anode to the plasma discharge, thereby reducing anode wear and providing longer term operation. Anode erosion is also reduced by the liquid cooling of the anode during use. The generator utilizes a relatively low capacitance for the cathode-to-anode discharge and a relatively high voltage and pulse repetition rate (frequency) to achieve continuous reproducible results.

    Abstract: An X-ray tube and an X-ray source including the same are provided. An anode housing portion (3) of an X-ray tube is provided with a pair of conductive flat surface parts (13d) so arranged as to be parallel to a reference surface perpendicular to an electron entering surface (5d) of an X-ray target and to sandwich the X-ray target. The reference surface includes a first reference line connecting the center of the electron exiting opening of an electron gun (11) and the center of the electron entering surface of the X-ray target and a second reference line intersecting with the first reference line on the electron entering surface and connecting the center of the electron entering surface and the center of an X-ray exiting window. With this constitution, the shape of the entering electron beam can be approximated to a circle by the action of the electric field produced between the electron entering surface of the X-ray target and the electron gun. Unlike conventional X-ray tubes, the tube does not have any hood electrode, the FOD can be shortened. Hence, a sharp magnified fluoroscopic image can be captured, and the magnification of the magnified fluoroscopic image can be increased.

    Abstract: An X-ray source (1) and an X-ray tube (4) in which a section (42) for shielding the securing portion (W) of a target support (18) and a second end opening (34) is formed when viewed from a first end of a bulb (20). Consequently, discharge between the first end of the bulb (20) and the securing portion (W) can be suppressed. Since a second end of the bulb (20) is formed as a constricted portion (37) and the second end opening (34) of the bulb (20) is secured to the target support (18), the shapes of the bulb (20) and the shielding section (42) can be simplified compared with conventional X-ray tubes where an inner tube section is formed in the bulb. With such a simple constitution, the stability of the electric field in the bulb (20) is enhanced at the time of X-ray generating operation and discharge in the bulb (20) can be suppressed effectively.
