Abstract: A method of fabricating a transmission target for an X-ray system is provided. The method includes forming a substrate and etching at least one via in the substrate. The method includes depositing a layer of seed metal on the surface of the substrate. The method includes filling the vias with a target metal to form target metal blocks.

Abstract: A multi-metal patterned anode for an X-ray detector is provided. The anode comprises a substrate and at least one group of disjointed circular features formed on the substrate, wherein the circular features are made from different metals. The circular features in different groups have different radii, and the circular features in the same group have the same radii. The groups of circular features are radially arrayed on the substrate. The substrate is made of diamond or beryllium.

Abstract: A method and apparatus for identifying a material in an object. An image of the object generated from energy passing through the object is obtained by a computer system. The computer system estimates attenuations for pixels in a sensor system from the image of the object to form estimated attenuations. The estimated attenuations represent a loss of the energy that occurs from the energy passing through the object. The computer system also identifies the material in the object using the estimated attenuations and known attenuation information for identifying the material in the object.

Abstract: A method and apparatus for inspecting an object in a virtual reality environment. Computed tomography scan data for the object is identified. A first group of dimensions for a model of the object and a second group of dimensions for the computed tomography scan data for the object are adjusted such that the first group of dimensions for a first group of features in the model corresponds to the second group of dimensions for a second group of features in the computed tomography scan data. The model and the computed tomography scan data are displayed by a game engine in the virtual reality environment on a display system. Graphical indicators in the virtual reality environment are displayed when a difference is present between features in the model and the features in the computed tomography scan data, enabling identifying the difference between the object and the model of the object.

Abstract: A method and apparatus for displaying a three-dimensional radiograph in a security scanner. A first X-ray image of an object is generated by the security scanner from a first viewpoint. A second X-ray image of the object is generated by the security scanner from a second viewpoint. The first X-ray image and the second X-ray image form a stereogram. The stereogram is displayed by the security scanner on a display system for the security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram. A parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of the object on the display system for the security scanner.

Abstract: An X-ray contrast sensitivity gauge is described herein. The contrast sensitivity gauge comprises a plurality of steps of varying thicknesses. Each step in the gauge includes a plurality of recesses of differing depths, wherein the depths are a function of the thickness of their respective step. An X-ray image of the gauge is analyzed to determine a contrast-to-noise ratio of a detector employed to generate the image.
