A Reconstruction Procedure for Thermoacoustic Tomography in the Case of Limited Boundary Data

Abstract

We derive an explicit method for reconstructing singularities of the initial data in a thermoacoustic tomography problem, in the case of variable sound speed and limited boundary data. In order to obtain this explicit formula we assume the metric induced by the sound speed does not have conjugate points inside the region to be observed.
