Abstract

With the view toward the realization of optical CT imaging, we have developed the simultaneous estimation technique of scattering (μ'_s) and absorption (μ_a) distributions and verified the feasibility in simulation. The usefulness of the proposed technique was verified in experiment with three-layer-structure models. The μ_a estimation error was less than 20% in the range of μ'_s = 0.75 – 2 /mm. Through this analysis, the usefulness of the proposed technique was verified.
