  • Three component x-ray bone densitometry
    Patent number: 6909771
    Abstract: The in vivo three component areal density composition of a patient along a transmitted x-ray beam is derived by raster-scanning a collimated x-ray beam across a bony region of the patient, with each point scanned at different energies, and using matrix equations with a priori spectra information to solve for the relative areal density of soft tissue, fat and bone.
    Type: Grant
    Filed: November 20, 2003
    Date of Patent: June 21, 2005
    Assignee: Board of Regents, The University of Texas System
    Inventors: Robert G. Waggener, Elizabeth Wieckowska
