Abstract :
A Bayesian optimization scheme is presented for reconstructing fluorescent yield and lifetime, the absorption coefficient, and the scattering coefficient in turbid media, such as biological tissue. The proposed method utilizes measurements at both the excitation and emission wavelengths for reconstructing all unknown parameters. A tissue phantom experiment uses the inversion strategy to reconstruct a spherical heterogeneity containing indocyanine green.
