内容提要：
Fluorescence photoacoustic tomography (fPAT) is a molecular  imaging modality that combines photoacoustic tomography (PAT) with  fluorescence imaging to obtain high-resolution imaging of fluorescence  distributions inside heterogeneous media. The objective of this work  is to study inverse problems in the quantitative step of fPAT where we  intend to reconstruct physical coefficients in a coupled system of  radiative transport equations using internal data recovered from  ultrasound measurements. We derive uniqueness and stability results on  the inverse problems and develop some efficient algorithms for image  reconstructions. Numerical simulations based on synthetic data are  presented to validate the theoretical analysis.
