Abstract: A method of generating an ultrasound elastic image includes: inducing a shear wave that propagates in a second direction by transmitting a first ultrasound signal including a push signal to an object in a first direction, by a curved array probe; transmitting a second ultrasound signal to the object and receiving an echo signal reflected by the object in response to the second ultrasound signal, via the curved array probe; and generating an elastic image of the object by using the received echo signal. The second ultrasound signal includes a plane wave having a straight line waveform parallel to the second direction.

Abstract: A method of analyzing elastography of tissue using a one-dimensional (1D) ultrasound probe. The method includes: acquiring two-dimensional (2D) ultrasound images with respect to a region of interest (ROI) of an object to be diagnosed, to which a shear wave is induced, using the 1D ultrasound probe; measuring a displacement of the shear wave from the acquired 2D ultrasound images; estimating a change rate in the displacement of the shear wave along a y-axis direction orthogonal to a 2D plane on which the 2D ultrasound images are shown, using the measured displacement; and analyzing elastography information of tissue in the ROI using the measured displacement and the estimated displacement change rate.
