Diffuse optical tomography errors resulting from uncertainty in the background optical properties

摘要

Abstract: We investigated the influence of uncertainties in the scattering and absorption coefficients of the background, the system error, the depth position of the object on the reconstructed image values of diffuse optical tomography using cw illumination. Nth born perturbation approach was used for generating forward data, and k-space diffraction tomography was used as inverse algorithm. We also examined the influences on reconstructing the perturbation in oxy-, deoxy-hemoglobin concentrations and their ratio.!12
