  • Method for processing digitized ultrasonic signals originating from an ultrasonic probe for the storage of and later reconstruction of the ultrasonic signals from the stored data
    Patent number: 5555180
    Abstract: A method for processing digitized ultrasonic signals originating from an ultrasonic probe for the storage and later reconstruction of the ultrasonic signals from the stored data. Each half-wave from the digitized data is stored as the maximum amplitude, polarity sign, and location on the time axis of the wave. Reconstruction of the signal from the stored data is effected by constructing a series of 180.degree. cosine curves from the stored data and connecting each successive cosine curve with the previous cosine curve.
