| Outline of Final Research Achievements |
We studied to develop a total imaging system for skin tissue, in which hyper-spectral images are acquired, simulated reflectance spectrum is fitted to measured spectrum in the 9-layered Monte Calro skin model, absorption and scattering coefficients are estimated for each of nine layres, and 3-D photon fluence distribution is obtained. In this study, especially, the photon fluence based on the reflected component only is treated to reconstruct the skin surface image with possibly realistic color. This may be useful for comparison with clinical skin images or visual observation by a medical doctor.
