Paper Abstract

To estimate the error of scattering coefficient spectrum determined by using double-integrating sphere system and inverse Monte Carlo method, optical properties of tissue phantom were measured. The tissue phantom was composed of hemoglobin, intralipid and gelatin. The thickness of samples (0.1-1.0 mm) and hemoglobin concentration (0.5-4.0 mg/ml) were changed and the effects of optical properties spectra were investigated. As the results, when the value of μa was large, μ's spectrum was not consistent with scattering theory. The higher hemoglobin concentration of samples was the lager the errors of μ's spectra were. The thinner the sample was, the smaller the errors were. However μa spectrum was not accurate when the sample was thin. It was predicted that when the sample thickness was 0.1 mm μ's spectrum was accurate. And when the sample thickness was 1.0 mm, μa spectrum was accurate.
