где Φdo - световой поток при максимальном диаметре диафрагмы;
Φdk - световой поток при уменьшенном диаметре диафрагмы;
Do - максимальный диаметр диафрагмы;
Dk - уменьшенный диаметр диафрагмы,
при значениях R, близких к единице, делают заключение о нормальном состоянии ткани, при значениях 2>R>1,1 делают заключение о существенном увеличении клеточной инфильтрации ткани на фоне умеренно выраженного отека, при R>>2 делают заключение о преобладании отека ткани, а при R<0,9 делают заключение о увеличении плотности ткани и/или увеличении степени клеточной инфильтрации.A method for determining the state of biological tissue by bringing a probe radiation source to it, measuring the luminous flux of the reflected light signal, at a certain diameter of the diaphragm of the integrating sphere comparing the data obtained with symmetrical and reference points and calculating the biophotometric coefficient R, characterizing the severity of the pathological process, characterized in that measure the luminous flux of the reflected signal at the maximum aperture diameter, and then reduce the diameter of the apertures to an arbitrary value in the range of 20-80% of the original, the light flux is measured again and determine the K coefficient which characterizes the biological tissue density, according to the formula:
where Φ do is the luminous flux at the maximum aperture diameter;
Φ dk is the luminous flux with a reduced aperture diameter;
D o - the maximum diameter of the diaphragm;
D k - reduced diameter of the diaphragm,
at values of R close to unity, a conclusion is made about the normal state of the tissue, at values of 2>R> 1.1, a conclusion is made about a significant increase in cellular tissue infiltration against a background of moderate edema, at R >> 2, a conclusion is made about the predominance of tissue edema, and at R <0.9, a conclusion is drawn about an increase in tissue density and / or an increase in the degree of cellular infiltration.
