dc.description.abstract |
We have simulated diffuse reflectance spectra of skin by assuming a wavelength-
independent scattering coefficient for the different skin tissues and using the
known wavelength dependence of the absorption coefficient of oxyand
deoxyhaemoglobin and water. A stochastic Monte Carlo method is used to convert
the wavelength-dependent absorption coefficient and wavelengthindependent
scattering coefficient into reflected intensity. The absorption properties of
skin tissues in the visible and near-infrared spectral regions are estimated by
taking into account the spatial distribution of blood vessels, water and melanin
content within distinct anatomical layers. The geometrical peculiarities of skin
histological structure, degree of blood oxygenation and the haematocrit index
are also taken into account. We demonstrate that when the model is supplied with
reasonable physical and structural parameters of skin, the results of the
simulation agree reasonably well with the results of in vivo measurements of
skin spectra. |
