Paper Abstract

A new nonperturbative method for studying diffuse photon imaging using frequency domain continous (CW) near-infrared (NIR) light source is developed. In solving the forward problem, this new method is in principle more accurate than the simple perturbation theory. Based on this method, a new image reconstruction algorithm is developed for the inverse problem. A test of this new imaging algorithm is provided by reconstructing images of cylindrical inclusions in uniform turbid media of cross-sectional sizes comparable to realistic human brains and breasts. Preliminary images obtained represent quite well the dimensions of the actual cylindrical object cross sections, with a spatial resolution of around 0.5 cm.
