Fast Monte Carlo inversion for extracting the optical properties of tubular tissues

Reconstruction of absorption coefficient \mu_{a} and scattering coefficient \mu_{s} is very important for applications of diffuse optical tomography and near infrared spectroscopy. Aiming at the early cancer detection of cervix and stomach, we present a fast inverse Monte-Carlo scheme for extracting \mu_{a} and \mu_{s} of a tubular tissue from the measurement on frequency domain. Results show that the computation time for reconstructing one set of \mu_{a} and \mu_{s} is less than 1 min and the r
