  • Patent number: 6904121
    Abstract: A method reconstructs 3-dimensional information of an object from projection images of said object acquired by a digital tomosynthesis system having an x-ray source following a trajectory relative to the object and a detector. The method comprises determining mathematical relationships between Fourier Transforms of logical slices through the object and Fourier Transforms of projection images of the object. Moreover, a digital tomosynthesis system includes a detector and an x-ray source traversing a trajectory a constant distance from a plane containing the detector. A computer of the digital tomosynthesis system reconstructs 3-dimensional images of an object by determining mathematical relationships between Fourier Transforms of logical slices through the object with Fourier Transforms of projection images of the object.

  • Patent number: 6888924
    Abstract: Geometry of a tomosynthesis system including a detector and an x-ray source is determined using fiducial markers with non-determined positions. The geometry is determined by arbitrarily identifying at least two markers within an imaged volume, at different relative distances between the detector and the x-ray source, without having projections located on a straight line for all different source positions, and locating the projections of the markers within at least two images acquired of the imaged volume. The at least two images correspond to different positions of a focal spot of the x-ray source.

  • Patent number: 6862337
    Abstract: A digital tomosynthesis system acquires a plurality of projection radiographs of an object and reconstructs structures of the object based on the acquired projection radiographs. The digital tomosynthesis system includes an x-ray source and a detector. The x-ray source emits a beam of x-rays, and moves in a linear trajectory relative to the detector.

  • Publication number: 20030149364
    Abstract: A method for generating an image of an object of interest includes acquiring a first three-dimensional dataset of the object at a first position using an X-ray source and a detector, acquiring a second three-dimensional dataset of the object at the first position using an ultrasound probe, and combining the first three-dimensional dataset and the second three-dimensional dataset to generate a three-dimensional image of the object.
