Abstract

An ultrasonic imaging of a low-frequency elastic wave which propagates inside the soft tissue-like medium is proposed. This method uses both the fundamental ultrasonic wave and the tissue harmonics ultrasonic wave which is produced by the nonlinear characteristic of the medium in order to reconstruct the wavefront of the low-frequency vibration. The accuracy of elastic wave velocity estimation of the proposed method is evaluated by numerical analysis. Examples of two-dimensional maps which show the elastic wave propagation inside the medium are shown.
