Research of the spectral diffuse reflectance of melanoma in vivo

The structure and principle of operation of information-measuring system of diagnostics of normal and pathological biological tissues from the spectrum of diffuse reflection. Research of spectrum of diffuse reflection of patients with melanoma and comparison of characteristics of normal skin relatively healthy recipient. The measurement results can be used by an expert system based on fuzzy logic for decision support physician about diagnosis and correction methods of treatment.

Multispectral control of water bodies for biological diversity with the index of phytoplankton

We performed mathematical modeling population dynamics of phytoplankton in aquatic ecosystems based on interspecific interactions and nutrient pollution and toxic substances. We proposed a method of measuring control multispectral television ecological status of water bodies on the parameters of phytoplankton.

The optical diagnostics of parameters of biological tissues of human intact skin in near-infrared range

Melanoma skin is difficult to diagnose in the early stages of development despite its location outside. Melanoma is difficult to visually differentiate from benign melanocytic nevi. In the work we investigated parameters of human intact skin in near-infrared range for different racial and gender groups. This allows to analyze statistical differences in the coefficient of diffuse reflection and use them in the differential diagnosis of cancer by optical methods subject.
