FIELD: medicine.SUBSTANCE: radiation is supplied onto a tissue into one or more points at wavelengths ? from the range of 350-1600 nm; a diffuse reflection P(L, ?) is measured at wavelengths of the supplied radiations for each lighting point; an absolute R(L, ?) or normalised r(L, ?) spectral-spatial profile of a tissue diffuse reflection coefficient, while the optical and biophysical parameters (X) are determined on the basis of analytic expressions representing multiple regressions between X and R(L, ?) or between X and r(L, ?) produced by measuring or calculating by Monte-Carlo method R(L, ?), r(L, ?) for a number of biotissue samples or control phantoms with the known optical and biophysical parameters; an implementing ensemble of the optical and biophysical parameters of the biotissue and respective spectral-spatial profiles R(L, ?), r(L, ?) for the ranges of the tissue optical and biophysical parameters.EFFECT: enhancement, higher measurement accuracy of the given parameters of the calibration measurements and use of the prior information.5 cl, 6 tbl, 7 dwg |
