  • Patent number: 10595805
    Abstract: Systems and methods for generating imaging biomarkers that indicate detectability or conspicuity of lesions that may be present in mammographic images are provided. In general, a task-based measure of a signal-to-noise ratio (“SNR”) measurement of a detection task is computed over a number of small regions-of-interest (“ROIs”) in an image, and the computed parameter is used to predict what detection rates should be if a lesion was present in the image. As such, the computed parameter can be used to define an imaging biomarker that is a “masking measure” that indicates the degree of conspicuity of lesions that may be present in a given a mammographic image.

  • Patent number: 8120683
    Abstract: An integrated application specific integrated circuit having a detection layer, a time delayed integration capability, data acquisition electronics, and a readout function is provided for detecting breast cancer in women. The detection layer receives x-ray radiation and converts the received energy to electron pairs, one of which is received by pixels. The time delay integration is on the chip and a part of the readout architecture. The detector may be a hybrid silicon detector (SiPD), a CdZnTe detector, or a GaAs detector.

  • Patent number: 7286632
    Abstract: A method and apparatus for determining a degree of deflection in a breast compression plate. The mammography apparatus further includes an optical measuring device. The method and apparatus involve (a) providing a pattern on the breast compression plate, the pattern being imagable by the optical measuring device, and having a plurality of local pattern indicia; (b) adjusting the breast compression plate to a selected height; (c) imaging the breast compression plate using the optical measuring device to provide an image of the pattern, the image having a plurality of local image indicia including an associated local image indicia for each local pattern indicia in the plurality of local pattern indicia; and (d) for each local pattern indicia in the plurality of local pattern indicia, determining an associated local deflection of the breast compression plate from the associated local image indicia.

  • Publication number: 20060167355
    Abstract: A method, computer software product and computer system for analyzing digital mammograms. The method, computer software product and computer system involve a generating phantom thickness object; receiving a set of dimensions for a breast; and, transforming the phantom thickness object to conform to the set of dimensions for the breast to provide the three-dimensional breast thickness object.
