Formalization of PDT-photosensitizer spectral data with spectral coordinates method

Abstract

A new method for spectral data formalization was developed. Spectral coordinates allows extracting specific properties of spectral components in order to convert physical experimental data into diagnostic data. Also visualization method is presented which allows placing spectral coordinates as a point onto orthogonal coordinates in order to perform statistical data accumulation, data clustering, and making following diagnostic assumptions. As experimental test data spectra collected in-vivo in patients were used.
