Abstract
Results obtained with an experimental Optical Tomography system, using a frequency domain technique and a cylindrical geometry are presented. In particular, problems occurring in the reconstruction of Optical Tomography images due to uncertainties in the values for relative refractive index and system calibration factor have been investigated. It is shown that considerable errors can arise in the values for the reconstructed absorption and diffusion images as a result of these uncertainties, and that these uncertainties can give rise to artifacts in the reconstructed images. In addition, the degeneracy between the absorption coefficient, (mu) a, and the diffusion coefficient, D, is shown for reconstruction from DC data, with the conclusion that for optimal reconstruction DC data cannot be discarded, and therefore an accurate system calibration remains a necessity.
