Abstract

An inverse image reconstruction approach that makes use of an algorithm based on the diffusion approximation of the radiative transport theory and a sequence of picosecond-duration slices of transmitted two-dimensional (2D) light intensity distribution for fast 3D image reconstruction is presented. The results of simulation and experiment for a cylindrical geometry are presented. Object localization in the lateral dimensions is better than that in the axial direction. The observed difference in axial and lateral resolutions are analyzed by introducing the concept of "longitudinal sensitivity".
