摘要: The present invention provides systems and methods for the spectroscopic determination of the physical characteristics of the tissue under observation by an autofluorescence or other endoscope without the requirement of contacting the tissue directly. The optical probe contained in the endoscope itself is passive and may be either built into the endoscope or positioned in a biopsy channel of same. The spectroscopic information, combined with other information provided by the endoscope such as total fluorescence, improves the sensitivity and specificity of the identification of precancerous or cancerous lesions.
