Abstract

The applicability of backprojection algorithms of filtered shadows that have been earlier developed for computer tomography is shown for the case of optical tomography of strongly scattering media. This opportunity is based on the presence of a long rectilinear part in the approximation of the statistical Photon Average Trajectories of photons propagating through the scattering medium. The results of numerical experiments showed that the quality of reconstruction using filtered backprojection algorithms do not surrender to that for multi-iterative algorithms, at much shorter reconstruction time.
