ABSTRACT

A model of photon migration in strongly scattering media with tissue like optical properties and a new method of direct absorbing inhomogeneity detection before image reconstruction using diffuse optical tomography (DOT), are presented. It is demonstrated that photon density maximum moves primarily to the center of an object. The method is based on preprocessing of the surface obtained from a collection of time-resolved data in the Cartesian frame with consecutive conformal mapping to cylindrical frame. The key feature of the method is application of late arriving photons (LAP) only.
