The theoretical analysis and numerical simulations show that the time reversal image I is very similar to the initial pressure function φ and that a resolution of σ≈0.036mm is feasible (for exact measurement data).
Reconstruction Algorithms for Photoacoustic Tomography in Heterogeneous Damping Media

Multi-Scale Factorization of the Wave Equation with Application to Compressed Sensing Photoacoustic Tomography
A multiscale factorization for the wave equation is proposed, which separates the data into a low frequency factor and sparse high frequency factors, and transfers sparsity in measurements domain to spatial sparsity of the initial pressure, which allows the use of sparse reconstruction techniques.
The quasi-reversibility method to numerically solve an inverse source problem for hyperbolic equations
A numerical method is proposed to solve an inverse source problem of computing the initial condition of hyperbolic equations from the measurements of Cauchy data by the quasi-reversibility method, and it is rigorously proved that the convergence of this method as the noise level tends to 0.

Reconstruction and time reversal in thermoacoustic tomography in acoustically homogeneous and inhomogeneous media
The paper starts with a comparative discussion of features and limitations of the three types of recent approaches to reconstruction in thermoacoustic/photoacoustic tomography: backprojection
Photoacoustic tomography in absorbing acoustic media using time reversal
The reconstruction of photoacoustic images typically neglects the effect of acoustic absorption on the measured time domain signals. Here, a method to compensate for acoustic absorption in
Exact and approximative imaging methods for photoacoustic tomography using an arbitrary detection surface.
Two universal reconstruction methods for photoacoustic computed tomography are derived, applicable to an arbitrarily shaped detection surface, by calculating the far-field approximation, a concept well known in physics, where the generated acoustic wave is approximated by an outgoing spherical wave with the reconstruction point as center.
Reconstructions in limited-view thermoacoustic tomography.
Three types of reconstruction methods are utilized: a filtered backprojection (FBP) approximate inversion, which is shown to work well for limited-view data, a local-tomography-type reconstruction that emphasizes sharp details (e.g., the boundaries of inclusions), and an iterative algebraic truncated conjugate gradient algorithm used in conjunction with FBP.
