Claim 10:
11. A method for distinguishing between different tissues during surgery, the method comprising:
directing radiation having a pre-determined wavelength toward a portion of a patient to illuminate and stimulate at least first and second tissues of the region of the patient into autofluorescence;
collecting radiation corresponding to the autofluorescence of the first tissue and the autofluorescence of the second tissue having wavelengths above a pre-determined wavelength threshold;
distinguishing between the radiation from the autofluorescence of the first tissue and the autofluorescence of the second tissue based on autofluorescence intensity; and
visibly highlighting, in the region of the patient, areas of the autofluorescence of the first tissue.
