Classical algorithms used for traveltime tomography are not necessarily well suited for
handling very large seismic data sets or for taking advantage of current supercomputers …

Tomographic imaging of seismic velocities is probably the most novel application of the
seismic method to high resolution exploration and monitoring of the subsurface. It is a …

SUMMARY A tomographic inversion technique that inverts traveltimes to obtain a model of
the subsurface in terms of velocities and interfaces is presented. It uses a combination of …

A tomographic inversion procedure is described and applied to a synthetic three‐
dimensional (3‐D) seismic refraction data set, demonstrating that tomography is capable of …

Wave-equation traveltime tomography tries to obtain a subsurface velocity model from
seismic data, either passive or active, that explains their traveltimes. A key step is the …

Nonuniqueness in traveltime tomographic velocity analysis is largely the result of
insufficiency in model parameterization. Traditional tomography parameterizes the model …

We have used a dense wide-angle data set to test a two-step procedure for the separate
inversion of first-arrival and reflection traveltimes. Data were collected in a complex thrust …

This paper describes the application of tomography to seismic travel-time inversion. There
are various implementations of travel-time tomography. In reflection tomography, sources …

In this paper, we propose a wave-equation-based travel-time seismic tomography method
with a detailed description of its step-by-step process. First, a linear relationship between the …

This paper presents a new traveltime inversion method based on the wave equation. In this
new method, designated as wave-equation traveltime inversion (WT), seismograms are …
