Abstract:
1. An ultrasound system, comprising: an ultrasound probe configured to receive ultrasound signals for obtaining a plurality of frames while applying compression to a living body during a predetermined time; a beam former configured to convert the received ultrasound signals into digital signals; an ultrasound data forming section configured to form ultrasound data corresponding to the plurality of frames using the digital signals output from the beam former; and a processor in communication with the ultrasound data forming section, wherein the processor is configured to: extract frames from a (n−1) calculate a first displacement between the n calculate a first strain using the first displacement between the n calculate strain mean values using the first strain, detect an optimal frame for forming an elastic image among the extracted frames based on the strain mean values, calculate strain based on a displacement between the optimal frame and the n form the elastic image using the strain corresponding to the optimal frame.
