摘要：

Isotropic traveltime tomography applied to numerical anisotropic model data causes artifacts that manifested themselves as ×-like inhomogeneities in the resulting tomograms. Even relatively weak anisotropy cannot be ignored if accurate estimates of velocity distribution are required. However, a low resolution image of an isotropic salt dome was fairly well reconstructed, even in the presence of anisotropy, using the dual tomography technique. -from Authors
