  • Ultrasound imaging system having post-beamformer signal processing using deconvolution algorithm
    Patent number: 6245016
    Abstract: A post-beamformer signal processing algorithm is utilized in a system for improving ultrasound B-scan resolution and contrast. The algorithm is based on a model of the imaging process that represents: 1) the shape of the pulse transmitted by the transducer and the frequency-dependent attenuation of that pulse as it propagates through tissue and back to the transducer; and 2) the effects of changes in frequency-dependent attenuation and in scatterer density as the pulse propagates across tissue boundaries and through cystic and calcified structures. The system provides substantial improvements in resolution and contrast as compared to standard envelope-detected imagery.
