Abstract: A method of performing shear wave elastography in tissue includes transmitting successively a series of ultrasound push pulses in the tissue in a region of interest (ROI) using a single array transducer. The acoustic intensities of the push pulses are sinusoidally modulated with a modulation frequency, Each push pulse generates an acoustic radiation force that pushes the tissue and creates an individual shear wave propagating through the tissue. The amplitudes of the shear waves, and therefore, the displacements produced by the push pulses, are positively proportionally to the intensities of the push pulses. The successively created individual shear waves with different amplitudes sum together to form a continuous, harmonic summed shear wave with a single frequency the same as the modulation frequency of the push pulses.
