System and method for ultrasound elastography and method for dynamically processing frames in real time

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 the elasticity of the target from a plurality of elasticity images corresponding to the received signals from the ultrasonic probe;
• calculate at least a quality parameter reflecting reliability 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 defined as a frame with a quality parameter that meets a preset quality requirement;
• and
• determine, when it is determined that the dynamic process start point frame exists in the sequence of corresponding frames of the plurality of elasticity images, whether to weight a current frame and a previous image and output a weighted result according to a result of judging whether the quality parameter of the current frame meets the preset quality requirement;
• wherein the display device is further configured to display the weighted result when it is determined to output the weighted result of the current frame and the previous frame.
