Reconstructions from photoacoustic imaging data run into the problem that there are too many physical parameters involved (optical absorption and scattering coefficients and the thermodynamic Grüneisen parameter) to be able to recover them uniquely. We want to show how additional measurements from an optical coherence tomography experiment can improve the situation and help to get a full quantitative reconstruction. Such a combined measurement could then be used as an acquisition method for an elastography setup.
