Abstract

The influence of three reconstruction algorithms on spatial resolution of optical diffuse tomography by Photon Average Trajecotries (PAT) method was investigated. The resolution was estimated using the model of spatially invariant linear filter by the conventient procedure usually used in CT. The resolution of absorbing inhomogeneities of model objects is shown to go for a theoretical limit of PAT method and the algorithms considered appears to reconstruct optical diffuse images without complementary limitations on spatial resolution.
