A novel ultrasound method for remote measurement of tissue elasticity is proposed. The method is based on acoustic shear wave and time delay estimation using PCA neural network. Compared to other shear wave elasticity imaging approaches, this method has advantages in that it can be recombined with current blood flow imaging equipment and estimates the tissue elasticity in real time with high resolution. Experiments are performed on a homogeneous tissue-mimicking phantom and results of tissue internal stain due to shear wave propagation are reported
