Abstract
A method and apparatus for generating a shear wave. The method comprises: transducers transmit ultrasound waves to a region of interest once; the ultrasound waves focus on at least two focal points in an acoustic field; and with shear wave sources corresponding to the at least two focal points that propagates in a direction perpendicular to a transmission direction of the ultrasound waves. A method and apparatus for detecting an ultrasound elasticity of a shear wave discloses, in a same ultrasound transmission, multiple focal points are gathered in an acoustic field by the ultrasound waves, under the joint effect of the multiple focal points, and a shear wave zone propagated in a direction perpendicular to a direction in which the ultrasound waves is transmitted is formed, so as to expand a propagation range of the shear wave in a tissue, so that detecting ultrasound waves can perform elasticity detection on the tissue in a large range.
