Claim One:
1. A method of employing multimodal spectroscopy to classify pancreatic tissue in vivo comprising the steps of: illuminating pancreatic tissue in vivo to produce a measurable spectroscopic event; collecting spectroscopic response data from the spectroscopic event, wherein the response data includes measurements derived from steady-state reflectance, steady-state fluorescence, and time-resolved fluorescence signals associated with the tissue; comparing the response data with a photon-tissue interaction model for the reflectance and fluorescence spectra to extract tissue parameters from the measured data and a multi-exponential decay model of the time-resolved fluorescence in order to extract amplitudes and lifetimes from the measured data; and classifying the tissue as either normal, adenocarcinoma or pancreatitis based on the comparisons.
