摘要：

In ultrasound Elastography, the resolution and accuracy of strain estimation are bounded by the sampling period when the echo signal is digitized. In this paper, we describe three new algorithms which based on multiresolution, time-shift property of Fourier Transform and sine function interpolation, respectively, for improving the precision of peak position estimation of cross-correlation function between echo signals obtained pre- and post- target tissue compression. Experimental results demonstrate that these methods bring about good effects.
