1. An elasticity imaging method, comprising:
transmitting an ultrasound wave to a target tissue;
receiving an ultrasound echo of the ultrasound wave returned from the target tissue;
obtaining an interference characteristic information, wherein the interference characteristic information represents a degree of interference to the target tissue;
displaying an interference characteristic waveform corresponding to the interference characteristic information;
determining whether the interference characteristic information meets a preset condition based on a degree of change in an amplitude value of the interference characteristic waveform;
when the interference characteristic information meets the preset condition, obtaining an elasticity image of the target tissue according to the ultrasound echo; and
when the interference characteristic information does not meet the preset condition, stopping obtaining the elasticity image of the target tissue according to the ultrasound echo,
wherein the interference characteristic information meeting the preset condition comprises: a maximum amplitude value or a maximum difference value of amplitude values of the interference characteristic waveform is not greater than a preset threshold, and the interference characteristic information not meeting the preset condition comprises: the maximum amplitude value or the maximum difference value of the amplitude values of the interference characteristic waveform is greater than the preset threshold.
