  • Patent number: 10624609
    Abstract: Systems and methods for performing shear wave elastography using push and/or detection ultrasound beams that are generated by subsets of the available number of transducer elements in an ultrasound transducer. These techniques provide several advantages over currently available approaches to shear wave elastography, including the ability to use a standard, low frame rate ultrasound imaging system and the ability to measure shear wave speed throughout the entire field-of-view rather than only those regions where the push beams are not generated.

  • Patent number: 9237878
    Abstract: A method for generation and analysis of shear waves in a subject with an ultrasound system. Multiple short ultrasound push pulses are applied, as a set and optionally more than once, to one or more push origins at the subject to produce first and second shear waves of large amplitudes and desired spatial distributions, which are separated in space and time and which have opposite polarity such that initial movements of the subject tissue, respectively caused by the first and second shear waves, occur in opposite directions. At least one mechanical property of the subject (including that represented by shear wave group velocity, phase velocity, and attenuation of a shear wave) is determined based at least in part on a distance between wavefronts of the first and second shear waves.

  • Patent number: 8734350
    Abstract: A system and method for measuring mechanical properties of a tissue using an ultrasound system is provided. Ultrasound energy is applied to the tissue using the ultrasound system in order to produce shear waves that propagate in the tissue. Measurement data are then acquired by directing ultrasound detection pulses into the tissue. Information about the intensity field of the ultrasound energy used to produce the shear waves is obtained and used to produce a correction factor. This correction factor is applied to the measurement data to correct the measurement data for errors arising from the geometry of the ultrasound energy used to produce the shear waves. From the corrected measurement data, mechanical properties of the tissue are calculated.
