  • Methods and apparatus for measuring body circumference
    Patent number: 8295570
    Abstract: Methods and apparatus for measuring body circumference are provided. One method includes acquiring dual-energy two-dimensional (2D) scan information from a dual-energy x-ray scan of a body and generating a dual-energy image of the body using the 2D scan information. The method further includes determining a circumference of at least one portion of the body based on the dual-energy scan information and the generated dual-energy image.
    Type: Grant

    Date of Patent: October 23, 2012
    Assignee: General Electric Company
    Inventors: Paul Markwardt, Randall Payne, Robert Washenko
  • Transverse scanning bone densitometer and detector used in same
    Patent number: 8165266
    Abstract: A scanning bone densitometer includes an x-ray source to produce x-rays and an x-ray detector receiving x-rays emitted from the x-ray source. The x-ray detector includes a cadmium tellurium (CdTe) semiconductor. The scanning bone densitometer also includes a controller moving the x-ray source and the x-ray detector along a transverse scanning path to acquire a plurality of scan images of an object of interest.

  • Monolithic X-ray detector with staggered detection areas
    Publication number: 20050247882
    Abstract: A monolithic solid-state detector using a staggered arrangement of pixels in multiple rows improves spatial resolution without requiring reduction in pixel size. Parallelogram shapes of CZT monolith allow tiling in one dimension without inefficient zones between monoliths. A scanning device using linear array of detectors with non-rectangular shape and staggered rows of detection elements such that no dead zones occur within a scan field.

  • Bone densitometer providing improved longitudinal studies
    Publication number: 20050096527
    Abstract: An x-ray densitometry system provides improved analysis of bone images taken of a patient over a course of time by comparing the images to deduce positioning errors and/or to correct positioning errors for improved quantitative assessment of the bone.
