  • Method and apparatus for X-ray radiographic imaging
    Patent number: 8842809
    Abstract: Embodiments of the invention relate to a method for x-ray radiography and apparatus for use in x-ray radiography. Specific embodiments can utilize a grid having a plurality of apertures therethrough with optical waveguides positioned in the apertures. The optical waveguides can incorporate a scintillating material, preferably throughout, that absorbs incident x-ray radiation and emits light that is then guided by the optical waveguide. In a specific embodiment, x-ray radiation incident on a first end of the aperture is absorbed by the scintillating material in the optical waveguide and light is emitted by the same scintillating material, a portion of which is guided by the optical waveguide to a second end of the aperture. In addition, secondary electrons created by absorption of the x-ray radiation by the scintillating material can be absorbed by the scintillating material to create more light such that a magnification effect can occur. The light exiting the second end of the aperture can then be detected.
