Abstract

The spectra K((lambda) ) and parameter p equals (epsilon) (1 - (mu) ) for the cases of high pathology of blood in a wide spectral region cannot be reconstructed with a high accuracy, using only for model of weak absorption. The analysis of a large experimental data shows that the possibility of absorption spectra K((lambda) ) reconstruction is taken into account by means losses on boundary of two medium slabs. The new algorithm of inverse problem solving is supposed for increasing of spectra K((lambda) ) accuracy. The absorption coefficients reconstruction of blood healthy persons and patients in a wide spectral region by using supposed algorithm and theoretical ones are analyzed. The possibility of derivative hemoglobins and their decomposition products concentration in blood is shown in future with more accuracy than earlier.
