1. A shear wave elasticity imaging method, comprising:
transmitting a first ultrasound wave to a target area of an object being examined to track a shear wave propagating in the target area;
receiving an ultrasound echo of the first ultrasound wave returned from the target area to obtain a first echo data;
obtaining an elasticity parameter of the target area according to the first echo data;
obtaining a motion parameter that represents a motion of the target area, wherein obtaining the motion parameter comprising:
obtaining at least two frames of ultrasound images of the target area according to the first echo data; and
obtaining a displacement of a tissue in the target area according to the at least two frames of ultrasound images; and
displaying the elasticity parameter and the motion parameter.
