摘要：

Two-dimensional (2D) shear modulus reconstructions are performed on an agar phantom using our previously developed ultrasound lateral Gaussian envelope cosine modulation method (LGECMM) together with multidimensional displacement vector measurement methods, i.e., the multidimensional cross-spectrum phase gradient method (MCSPGM), the multidimensional autocor-relation method (MAM) and the multidimensional Doppler method (MDM). The accuracies of the obtained 2D reconstructions are compared with each other in addition to those of 1D reconstructions obtained from the respective ratios of lateral and axial strains.
