The apparatus, method and computer-readable medium may photograph an object using an X-ray of at least two energy bands to output X-ray images, predict a component ratio of the object using the X-ray images, calculate a length of the object for each of the at least two energy bands using an intensity of the X-ray images, when the object is configured in the predicted component ratio, and verify whether an error in the component ratio occurs by comparing the lengths of the object calculated for each of the at least two energy bands. | 2011-05-12 |
20110110490 | METHOD AND APPARATUS FOR X-RAY RADIOGRAPHIC IMAGING - 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. | 2011-05-12 |
