Global seismic tomography: the inverse problem and beyond
Inverse Problems, 1998Global seismic tomography has produced a great amount of robust information concerning the three-dimensional extent of the Earth's internal structure. This has stimulated a multidisciplinary discussion aimed at understanding the mechanisms which govern the internal evolution of our planet.

The Leading Edge, 2005
One of the main challenges in seismic imaging is the estimation of sufficiently accurate background velocity models in the presence of complex geology. In this paper we show the use of a differential semblance in angle or DSA (Symes and Carazzone, 1991; Brandsberg-Dahl et al., 2003) misfit function to perform ray-based angle tomography on PP and its ...

A Breviary of Seismic Tomography
2008This is the first textbook to cover the essential aspects of the topic at a level accessible to students. While focusing on applications in solid earth geophysics, the book also includes excursions into helioseismology, thereby highlighting the strong affinity between the two fields. The book provides a comprehensive introduction to seismic tomography,

Fundamentals of Seismic Tomography
1994We define tomography as an imaging technique which generates a cross-sectional picture (a tomogram) of an object by utilizing the object's response to the nondestructive, probing energy of an external source. Seismic tomography makes use of sources that generate seismic waves which probe a geological target of interest.

Methodology of Seismic Tomography
2015In this chapter, we first introduce the basic principles of seismic tomography and discuss the common features and differences between seismic tomography and the medical CT-scan. Considering the fact that many different kinds of tomographic studies have been made and a large number of tomography-related technical terms are used in the literature, we ...

Image Reconstruction in Seismic and Medical Tomography
Journal of Environmental and Engineering Geophysics, 2008Abstract Tomography has been used for more than 40 yr in medical science and its success is well known. One of the most important reasons for the success of medical tomography compared to seismic tomography is the data-acquisition geometry.
