Abstract: A probe irradiates an ultrasound wave to an object to induce a shear wave and first elasticity information is obtained according to a first calculating scheme. An internal region of interest of the object is set based on shear modulus values included in the first elasticity information. Second elasticity information is obtained based on the shear wave induced to the internal region of interest, according to a second calculating scheme. Accurate elasticity information is acquired by using the first and second elasticity information to obtain third elasticity information from which an elastography image is generated for display to a user.

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.
