Anisotropic Beam-Stack Kirchhoff vs Wave Equation Imaging on PC Clusters

A-02 ANISOTROPIC BEAM-STACK KIRCHHOFF VS WAVE EQUATION IMAGING ON PC CLUSTERS Abstract 1 This paper discusses advanced imaging in acoustic elastic and anisotropic 3D media on large massively-parallel personal computer clusters. The focus is on parameter estimation methods and the technology pertinent to image data recorded over such models. Both synthetic and real data sets are used to demonstrate that existing technology though computationally intensive is eminently feasible on very attractively priced hardware. While the beam-stack approach to Kirchhoff migration has significant speed advantages full wave-equation methodologies are shown to provide superior accuracy and images.
