Abstract

Shear wave elastography is useful for quantitatively evaluating tissue elasticity by measuring the speed of a shear wave induced within the body by acoustic radiation force. We proposed a pushing-and-tracking sequence, coded push-pulse excitation to increase the signal-to-noise ratio (SNR) of the observed shear wave propagation without increasing measurement time and push-pulse amplitude1). In this study, we irradiate multiple coded-pulse sequences from different locations at the same time and separate overlapped shear waves by decoding to quickly image a wider area with high SNR. The feasibility of the proposed method was validated in phantom experiments.
