  • Patent number: 10522317
    Abstract: An X-ray tube includes an anode that conducts a high voltage that can be greater than 120 kV, and in particular greater than 300 kV, and heats up during operation. The anode is connected in a thermally conductive way to a heat sink, which has a base body composed of a metal with a heat absorbing surface for coupling to the anode as a heat source and a heat dissipating surface that is enlarged by means of heat dissipating elements that are connected to the base body. The heat dissipating elements are composed of an electrically insulating material having a thermal conductivity on the same order of magnitude as that of the metal of the base body, and have a height (H) starting from the base body of the heat sink so that there is a sufficient insulation breakdown resistance relative to the surroundings of the X-ray tube.

  • Patent number: 10216866
    Abstract: Systems and methods for modeling are provided. The method can include acquiring scan data associated with a plurality of x-ray projections of an item. The method can further include determining at least one closed boundary curve associated with the item. For example, the method can determine a first maximum area based on the scan data and determine at least one edge of the first maximum area. The method can further generate a model of the item using the closed boundary curve and a first material specific parameter for a material within the closed boundary curve. The method can utilize the model to generate computed scan data, compare the computed scan data to the scan data, and determine a goodness of fit. The method can further adjust the model of the item by altering at least one of the closed boundary curve and the material specific parameter.

  • Patent number: 10163200
    Abstract: This disclosure relates to a system and method for detecting an item having at least one symmetry property inside an inspection object based on at least one transmission image. The method includes the steps: (a) detection of edges of individual items contained in the transmission image in order to produce an edge image; and (b) detection of the item by determining a symmetry line that can be associated with an item with at least one symmetry property contained in the transmission image based on pairs of edge picture elements of the edge image that are positioned symmetrically to each other relative to the symmetry line; and in step (b), in determining the symmetry line in the edge image, the only edge picture elements that are taken into account are those for which the symmetry line lies in an item contained in the transmission image, to which item the edge belongs.
