Abstract:
1. A system configured to classify a tissue pathology comprising: an optical probe configured to measure the biomedical optical spectra data from a tissue; and a classification system coupled to the optical probe comprising a plurality of support vector machines with embedded error rejection to classify the biomedical optical spectra data from the tissue; wherein each of the plurality of the support vector machines with embedded error rejection is configured to classify a different region of the optical spectra data from the tissue, the classification comprising: using feature selection to determine the regions of greatest difference between the average spectrum for dysplastic and non-dysplastic tissues classifying a first region of the biomedical optical spectra data from the tissue using a first classifier; classifying a second region of the biomedical optical spectra data from the tissue using a second classifier, the first region being different than the second region; and combining the classification of the first classifier with the classification of the second classifier to determine a classification of the tissue, wherein the first and the second classifier cover optical spectra data from wavelength 330-600 nm and/or 330-400 nm; wherein the classification of the first classifier and the classification of the second classifier is selected from the group consisting of positive, negative and rejected.
