  • The main processing steps can be summarized as followings: 1) To arrange the ultrasound signals obtained at the proximal and distal locations into segments; 2) To obtain the transient time shifts of each segment between two consecutive frames; 3) To calculate the displacement waveforms using the transient time shifts and the speed of ultrasound in soft tissue; 4) To detect the peaks of the sinusoidal displacement waveforms; 5) To detect the time delay between each pair of the peaks obtained at the same depth; 6) To calculate the overall time delay between the two waveforms by averaging all the time delay values; 7) To calculate the shear wave velocity using its propagation time and distance.
