  • Patent number: 10448911
    Abstract: Medical images are acquired in a tomosynthesis process. Processed 3D volume data representing a target acquired from scanning may be viewed from a set of forward projection directions, in which one or more forward projections through the processed 3D volume data is oblique relative to a central acquisition direction of the scanning process. The first set of forward projections is then displayed as a set of synthetic mammograms. Therefore, a medical practitioner can more easily identify abnormalities within a target volume, because the relative displacement of abnormalities at different depths in the target volume will change at different rates dependent on the viewing angle as the viewing position is moved around the target.

  • Patent number: 10296808
    Abstract: The present invention relates to X-ray imaging technology as well as image post-processing. Particularly, the present invention relates to a method for computer aided detection of structures in X-ray images as well as an X-ray system. A computer aided detection algorithm visibly determines tissue structures in X-ray image information and subsequently matches the shape of a determined tissue structure with a library of known tissue structures for characterizing the type of determined tissue structure. The determination of a tissue structure and thus the characterization of the type of the tissue structure may be enhanced when employing also spectral information, in particular energy information of the acquired X-ray image.
