We have developed a technique to estimate the spatial distribution of the absorption coefficient (a) of turbid medium by the time-resolved measurement of backscattered light, and verified its feasibility in simulation and experiments. For accurate estimation of the a distribution, accurate scattering property of the medium is essential. Here, we newly developed a technique to estimate the accurate scattering coefficient (s) by reducing the effect of the absorption heterogeneity. To estimate the a more accurately, we also devised a new technique in which we attach a diffuser plate with known s at the body surface. The feasibility and the usefulness of these techniques were verified in the Monte Carlo simulation. |
