Optical diagnostics of malignant and benign skin neoplasms

In this work the study of the optical properties of skin tissues using Raman spectroscopy and autofluorescence analysis was performed. The analysis of different skin neoplasms was carried out based on the Raman and autofluorescence spectra stimulated by 785 nm laser. In this study the spectral data was processed by different mathematical methods allowed for effective classification of malignant and benign tumors. The proposed diagnostic methods helped to achieve 82.1-87% differentiation accuracy of skin neoplasms.
