| titleOfInvention | Method of biological tissues analysis for protoporphyrin fraction |
| abstract | FIELD: medicine; surgery. n SUBSTANCE: method involves spectroscopy with helium-neon laser-induced (632.8 nm) fluorescence excitation and recording of autofluorescence spectra as a data array consisting of fluorescence strengths for sequence of wave lengths 649 nm to 850 nm in pitch 0.43 nm {Z 1 , Z 2 , Z 3 …Z n }. It is combined with forming a data array consisting of fluorescence strengths of keratin {Y 1 , Y 2 , Y 3 …Y n } and portoporphyrin IX {X 1 , X 2 , X 3 …X n } for the same wavelengths. Portoporphyrin IX fraction is defined as proportional to specific fraction of its fluorescence within total autofluorescence spectrum calculated by formula: where {k 1 , k 2 …k n } and {l 1 , l 2 …l n } are calculated by formulas: where α and β are calculated by formulas: where {a 1 , a 2 …a n }, {b 1 b 2 …b n }, {ab 1 ab 2 …ab n }, {f 1 f 2 …f n }, {fa 1 fa 2 …fa n }, {fb 1 fb 2 …fb n } are calculated by formulas: n n n n n n n where Xav, Yav and Zav are calculated by formulas: X av = (X 1 +X 2 +X 3 …X n )/n; Y av = (Y 1 +Y 2 +Y 3 …Y n )/n; Z av = (Z 1 +Z 2 +Z 3 …Z n )/n, where n is a number of records in the data arrays consisting fluorescence intensities. n EFFECT: method allows for biological tissues analysis for portoporphyrin IX fraction with elimination of errors related to complex compound character of total autofluorescence spectrum. n 2 dwg, 2 ex |
