  • Ultrasound imaging system with pivoting breast compression plates
    Patent number: 9107630
    Abstract: An ultrasound breast imaging assembly includes first and second compression plates angled with respect to one another, a breast compression area defined between the first and second compression plates, at least one pivot assembly, and an ultrasound probe. The pivot assembly allows relative motion between the first and second compression plates. The ultrasound probe, which is configured to translate over one of the first and second compression plates, includes an active matrix array (AMA) positioned on one of the first and second compression plates.
    Type: Grant

  • Tone scale transformation for radiological images
    Patent number: 8064665
    Abstract: A method for transforming radiological image data from a digital receiver obtains digital image data values from the digital receiver and compensates for exposure response differences between a screen film system and the digital receiver. Modulation transfer function differences between the screen film system and the digital receiver are compensated and noise content at frequencies approaching the Nyquist frequency for the digital receiver is suppressed.
