Title: Reconstruction formulas for Photoacoustic Imaging in Attenuating Media,
Abstract: In this paper we study the problem of photoacoustic inversion in a weakly
attenuating medium. We present explicit reconstruction formulas in such media
and show that the inversion based on such formulas is moderately ill--posed.
Moreover, we present a numerical algorithm for imaging and demonstrate in
numerical experiments the feasibility of this approach.
