  • Ultrasonic tissue imaging method and apparatus with doppler velocity and acceleration processing
    Patent number: 5285788
    Abstract: An ultrasound tissue imaging system having an acoustic transducer, B-mode imaging means to produce with said transducer an electronically scanned B-mode image of tissue under examination, Doppler imaging means that accepts and processes large amplitude, low frequency signals to produce with said transducer an electronically scanned acoustic image of moving tissue, and color display means for displaying the B-mode image as a two-dimensional image with echo intensities encoded using a first mapping function and for simultaneously displaying Doppler information from moving tissue as a two-dimensional image using a second and distinct mapping function that is spatially coordinated with and superimposed upon said B-mode image to augment the B-mode image.
    Type: Grant
    Filed: October 16, 1992
    Date of Patent: February 15, 1994
    Assignee: Acuson Corporation
    Inventors: James W. Arenson, Ismayil M. Guracar, Janna G. Clark, Marc D. Weinshenker
