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.
