Abstract

Geotomography has emerged from medical tomography but unlike medical tomography it largely does not work well. Why it happens? The answer is trivial: seismic experiments are different from medical and do not suit tomographic procedure. What can be done? To reject tomography as a tool for velocity reconstruction or to adopt it with modifications? Geotomography is probably a unique tool for velocity reconstruction. Conventional velocity analysis is too simplistic and is limited to layered media which do not bear much interest. In this presentation we introduce a possibility to significantly improve tomography and to make use of it in real situations related to typical seismic experiments. We achieve it with the help of the so-called compensation operator which reduces the dependence of results upon angular coverage and thus adjusts it to real world.
