Paper Abstract

We present results on time-resolved transillumination imaging by using the cumulant expansion solution to the transport equation for temporal extrapolation. The resolution study involves measuring the edge response function (ERF) for a mask embedded in a liquid phantom at near-IR wavelengths, obtaining the integration-time-dependent resolution for different phantom widths and verifying this spatial resolution by resolving two objects inside the phantom. We also present results on the values of different parameters of the phantom materials and the feasibility of this method to characterize the absorption and scattering coefficients of a turbid medium.
