In this talk we show the use of high frequency asymptotic approximation to the solution of the wave equation in photoacoustic tomography (PAT). We consider ray tracing, a technique that involves solving the wave equation along the trajectories of a Hamiltonian system. We evaluate the quality of the ray tracing solutions to both the forward and inverse problem against a full wave solution obtained using a k-space method implemented in k-Wave Toolbox . The major benefit of ray tracing approach versus the full wave solution is that the solution along each ray can be obtained independently and at a much lower cost than the full solution.  B. E.
