Query: Inverse Problems of Combined Photoacoustic and Optical Coherence
  Tomography   Optical coherence tomography (OCT) and photoacoustic tomography (PAT) are
emerging non-invasive biological and medical imaging techniques. It is a recent
trend in experimental science to design experiments that perform PAT and OCT
imaging at once. In this paper we present a mathematical model describing the
dual experiment.
  Since OCT is mathematically modelled by Maxwell's equations or some
simplifications of it, whereas the light propagation in quantitative
photoacoustics is modelled by (simplifications of) the radiative transfer
equation, the first step in the derivation of a mathematical model of the dual
experiment is to obtain a unified mathematical description, which in our case
are Maxwell's equations. As a by-product we therefore derive a new mathematical
model of photoacoustic tomography based on Maxwell's equations.
  It is well known by now, that without additional assumptions on the medium,
it is not possible to uniquely reconstruct all optical parameters from either
one of these modalities alone. We show that in the combined approach one has
additional information, compared to a single modality, and the inverse problem
of reconstruction of the optical parameters becomes feasible.
