The invention relates to an
ultrasonic imaging system for elasticity measurement. The
ultrasonic imaging system comprises a probe, an
ultrasonic imaging device, a controlling and
processing device and a
display device, wherein the probe comprises a low-
frequency oscillation driving device for generating oscillation and forming a shearing wave propagating from
human body surface to tissues, and an
ultrasonic transducer array for sending an ultrasonic
signal to the tissues and receiving an ultrasonic
echo signal; the ultrasonic imaging device is used for driving the
ultrasonic transducer array to send the ultrasonic
signal and receive and process the ultrasonic
echo signal according to loaded imaging parameters; the controlling and
processing device is used for controlling the low-
frequency oscillation driving device and the ultrasonic imaging device to process the ultrasonic
echo signal so as to obtain a two-dimensional ultrasonic image and elasticity information of the tissues; and the
display device is used for displaying the two-dimensional ultrasonic image and the elasticity information. The
system and elasticity measuring method can simultaneously obtain the two-dimensional ultrasonic image and the elasticity information of the tissues, thereby improving
clinical diagnosis accuracy; and the probe can realize precise positioning under the guiding of the two-dimensional ultrasonic image without considering displacement compensation, thereby improving convenience and accuracy of
tissue elasticity measurement.
