  • Phase retrieval in phase contrast imaging
    Patent number: 6493422
    Abstract: A method of obtaining in image of the phase change introduced by an object in penetrating radiation incident on the object includes irradiating the object with penetrating radiation having high lateral spatial coherence, and receiving at least a portion of the radiation at a detector after the radiation has merged from the object and thereby obtaining and storing at least two intensity records for the received radiation each including intensity values at predetermined intervals. These values are utilized to derive a grid of values defining an image of the phase change introduced by the object in the penetrating radiation. The intensity records are obtained at a uniform finite distance after the radiation has emerged from the object, and are for respective different energy distributions of the detected radiation. Apparatus is also disclosed.
    Type: Grant

    Date of Patent: December 10, 2002
    Assignee: X-Ray Technologies Pty, Ltd.
