Abstract
A first-order estimation method of shear wave velocity, includes the steps of demodulating entry data, and obtaining a complex angle value, matrix average, offset matrix, displacement matrix and shear wave velocity. According to the method, the main contour of the displacement curve is extracted by the quadrature decomposition of matrix, thereby improving the signal quality of the shear wave estimation. Unlike conventional method which needs estimating twice, the shear wave displacement curve can be estimated directly to reduce estimation errors and improve estimation efficiency.
