  • Imaging method based on attenuation, refraction and ultra-small-angle-scattering of x-rays
    Patent number: 6947521
    Abstract: A method for detecting an image of an object by measuring the intensity at a plurality of positions of a transmitted beam of x-ray radiation emitted from the object as a function of angle within the transmitted beam. The intensity measurements of the transmitted beam are obtained by a crystal analyzer positioned at a plurality of angular positions. The plurality of intensity measurements are used to determine the angular intensity spectrum of the transmitted beam. One or more parameters, such as an attenuation property, a refraction property and a scatter property, can be obtained from the angular intensity spectrum and used to display an image of the object.

  • Diffraction enhanced x-ray imaging of articular cartilage
    Patent number: 6577708
    Abstract: A method and system for detecting an image of an object, particularly a soft tissue material. A generated x-ray beam is transmitted through the soft tissue material. A transmitted beam is directed at an angle of incidence upon a crystal analyzer. An image of the object is detected from a beam diffracted from the crystal analyzer either at or near a peak of a rocking curve of the crystal analyzer. The method and system of this invention is particularly useful for analyzing images of cartilage.
