Abstract

Time-resolved and continuous wave diffuse transmittances of near IR light through cylindrical phantoms were measured for the purpose of inhomogeneity detection and image reconstruction. Performed model experiment for homogeneous and inhomogeneous cylindrical phantoms provides a complete experimental data set for optical tomography. Some of the acquired data are presented. Possibility to use them for validation of analytical and numerical models of photon propagation is demonstrated. Good agreement with an analytical solution and 2D FEM simulated data was reached. A new index for inhomogeneity detection is introduced and its effectiveness is demonstrated.
