Quantitative Photoacoustic Imaging in the Acoustic Regime using SPIM

, 2017
While in standard photoacoustic imaging the propagation of sound waves is modeled by the standard wave equation, our approach is based on a generalized wave equation with variable sound speed and material density, respectively.
