Photon migration in a cylindrical phantom: numerical and experimental studies

By using both picosecond time-resolved spectroscopy and Monte Carlo simulations, we studied photon migration in a cylindrical phantom. Fan beam style source-receiver geometry was considered. The influence of inhomogeneities inside the phantom on impulse response of short incident light was studied considering a black body located at various positions inside the scattering medium. Applicability of time gating technique to the fan beam geometry for enhancement of image resolution was also examined.
