Photoacoustic Tomography With Spatially Varying Compressibility and Density
Zakaria Belhachmi, Thomas Glatz, Otmar Scherzer
This paper investigates photoacoustic tomography with two spatially varying acoustic parameters, the compressibility and the density. We consider the reconstruction of the absorpti…

A Direct Method for Photoacoustic Tomography with Inhomogeneous Sound Speed
Zakaria Belhachmi, Thomas Glatz, Otmar Scherzer
The standard approach for photoacoustic imaging with variable speed of sound is time reversal, which consists in solving a well-posed final-boundary value problem for the wave equa…
