1. a method comprises:

  • Apply the first ultrasonic pulse to produce the shearing wave along first direction in described biological tissue to biological tissue;

    The ultrasonic pulse be focused is transmitted in described biological tissue along second direction;

    Reception is from one or more first ultrasonic signals that generate in response to focused on ultrasonic pulse of described biological tissue;

    One or more the first ultrasonic signals based on received detect the described shearing wave in described biological tissue;

    Determine first group of at least one the shearing wave propagation characteristic be associated with detected shearing wave;

    Apply the second ultrasonic pulse to produce the second shearing wave along third direction in described biological tissue to biological tissue;

    By the second ultrasonic pulse of being focused along four directions to being transmitted in described biological tissue;

    Reception is from one or more second ultrasonic signals that generate in response to the second focused on ultrasonic pulse of described biological tissue;

    One or more the second ultrasonic signals based on received detect described the second shearing wave in described biological tissue;

    Determine second group of at least one the shearing wave propagation characteristic be associated with detected the second shearing wave;

    Determine the 3rd group of at least one shearing wave propagation characteristic based on described first group of at least one propagation characteristic and second group of at least one propagation characteristic;

    AndShow described the 3rd group of at least one shearing wave propagation characteristic.
