摘要： The present invention is directed to an ultrasound system and a method of forming an elastic image, which are capable of preventing the distortion of the elastic image. The persistence of the previous frame and the present frame is performed after moving the boundary pixels set up in the previous interest frame to the boundary pixels in the present interest frame. This is so that the distortion of the elastic image may be reduced and the signal to noise ratio may be increased.
