Basic physical principle of shear-wave elastography (SWE). A perpendicular stress force (acoustic radiation force) is applied to the tissue, which causes the generation of shear waves. The velocity of the shear wave could be measured by obtaining radiofrequency images with a high frame rate, which can be used to generate a tissue displacement map. Tissue displacements are used to calculate the shear-wave velocity (Vs) and shear modulus (G)
