[Experimental study of colorectal cancerous autofluorescent spectra induced by laser]

The researches reported in this article are focused on the autofluorescent signal collection of colorectal tissues by laser induced autofluorescent diagnostic system, and on the signal processing by power spectra and networks methods, Pretty good clinical diagnostic sensitivity and specificity are acquired. These may serve as a foundation on which to develop a system for diagnosis of colorecal cancer.
