“…The first, Euclidean distance δ, is simply a measure of the squared error between the resulting tomo gram and the actual test profile. It is defined by [12] (Xj X)) 1 (7) where η is the number of cells, Xj is the reconstructed estimate, and X) is the assigned test profile. Another, in a sense more qualitative, method of com parison is that of boundary definition by minimum variance partitioning [13].…”

The application of tomograpbical techniques to geophysical monitoring and exploration has been extended to media where refraction and reflection effects may be significant. The result is an iterative refinement scheme which is unstable in its original formulation. This paper presents the stability improvements of selective smoothing and path elimination which enable the reconstruction process to converge to an accurate solution. By use of the objective error measures of Euclidean distance and boundary definition by minimum variance partitioning, tomograms produced by this improved technique are shown to be superior to those obtained by traditional straight-tine geotomography. Guidelines for practical applica tion are presented.

“…The solution for the problem of incorporating diffraction for geophysical tomography may be an iterative refinement process similar to the one developed in this paper. It should be noted that Boerner et al have extended Devaney's scalar theory for the case of vector diffraction tomography [7].…”
