  • Apparatus and method for analyzer-based contrast imaging with a polychromatic beam
    Patent number: 11576636
    Abstract: A method and system for detecting an image of an object in an analyzer-based system with a polychromatic x-ray beam from an x-ray source, wherein an analyzer crystal and a detector simultaneously acquire a rocking curve of the x-ray beam for all energies of the x-ray beam. The x-ray beam is diffracted through the object using an asymmetrical monochromator. A detector movement is synchronized with one of the x-ray source or the object. The synchronization includes moving the detector at a first rate that is different than a second rate of the object or the x-ray source, wherein a ratio between the first rate and the second rate is determined by the magnification of the system.
    Type: Grant
    Filed: May 6, 2020
    Date of Patent: February 14, 2023
    Assignee: ILLINOIS INSTITUTE OF TECHNOLOGY

  • Apparatus and method for enhanced early photon detection in optical projection tomography
    Patent number: 10986998
    Abstract: A system and method for optical tomography including illuminating an object with pulsing stimulus light and pulsing the stimulus light at a repetition frequency having a pulse period that is greater than a dead-time of a detector. Coordinating the pulse with the dead-time of the detector allows for higher powered light source and improves early photon detection.
