Abstract :
Summary from only given. Optical diffusion imaging, where the scattering and absorption properties of tissue are reconstructed from noninvasive measurements, offers potential advantages of safety and diagnostic specificity over other imaging modalities. In addition, fluorescent contrast agents may provide enhanced chemical specificity, with greater potential to distinguish between diseased and healthy tissue. Imaging simulations of fluorescence lifetime and yield have assumed known scattering and partially known absorption properties. In this work we demonstrate a Bayesian reconstruction in which absorption and scattering parameters at the excitation and emission wavelengths are imaged, in addition to the fluorescent yield and lifetime.
