1. A system for ultrasound elastography, comprising:
an ultrasonic probe that emits an ultrasonic beam to a target to be detected and receives ultrasonic echoes from the target to obtain received signals;
a processor that performs an elasticity process on the received signals from the ultrasonic probe to obtain a plurality of elasticity images; and
a display device that displays one or more of the plurality of elasticity images;
wherein the processor is configured to:
extract elasticity information representing an elasticity of the target from the plurality of elasticity images corresponding to the received signals from the ultrasonic probe;
calculate at least a quality parameter reflecting quality of each elasticity image of the plurality of elasticity images corresponding to the elasticity information;
identify whether a dynamic process start point frame exists in a sequence of corresponding frames of the plurality of elasticity images, wherein the dynamic process start point frame is a frame with the quality parameter that meets a preset quality requirement; and
in response to determining that the dynamic process start point frame exists in the sequence of corresponding frames of the plurality of elasticity images:
obtain a current frame, wherein the current frame is any frame behind the dynamic process start point frame;
determine whether the quality parameter of the current frame meets the preset quality requirement; and
when the quality parameter of the current frame meets the preset quality requirement, weight the current frame and a previous frame and output a weighted result,
wherein the display device is further configured to display the corresponding weighted result, that is determined to be outputted by the processor.
