  Standard photoacoustic tomography (PAT) provides data that consist of
time-dependent signals governed by the wave equation, which are measured on an
observation surface. In contrast, the measured data from the recently invented
full-field PAT is the Radon transform of the solution of the wave equation on a
spatial domain at a single instant in time. While reconstruction using
classical PAT data has been extensively studied, not much is known about the
full-field PAT problem. In this paper, we study full-field photoacoustic
tomography with spatially variable sound speed and spatially variable damping.
In particular, we prove the uniqueness and stability of the associated
single-time full-field wave inversion problem and develop algorithms for its
numerical inversion using iterative and variational regularization methods.
Numerical simulations are presented for both full-angle and limited-angle data
cases
