Abstract: A method of measuring propagation of a shear wave by using an ultrasound transducer includes generating a shear wave inside the object, setting a region of interest (ROI) on which propagation of the shear wave is to be observed, and determining a position of a second focus on which ultrasound signals are to be directed to obtain information about the ROI, irradiating the ultrasound signals toward the second focus, and receiving echo signals reflected from the ROI.

Abstract: A method of displaying an elastography image and an ultrasound diagnosis apparatus performing the method are provided. The method includes transmitting an ultrasound signal to an object, receiving a response signal to the transmitted ultrasound signal, determining ultrasound image data based on the received response signal, determining displacement image data based on the determined ultrasound image data, generating elastography images based on the determined displacement image data, dividing the elastography images into sections based on a criterion, and determining a representative elastography image of each of the sections based on one or more elastography images in each of the sections and quality information of the one or more elastography images, the quality information being based on a strain of a first elastography image among the one or more elastography images. The method further includes displaying the representative elastography image.

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.
