Imaging through highly scattering media with transmitted photons with the shortest flight times is limited ultimately by the available number of photons with sufficiently short paths. A method is described that enhances the performance of the time-resolved imaging technique. A least-squares fit was obtained between the measured temporal distributions of transmitted light and a model of photon transport based on the diffusion approximation to the radiative transfer theory. Images constructed from the model estimates of short-path-length photon intensities provide information on internal structure, with a significantly improved signal-to-noise ratio compared with those that would be obtained directly from the data.
