【Abstract】 <Abstrcat>Drug-fluorescence spectroscopy system for diagnosis and localization of early nasopharyngeal carcinoma has been developed based on the technique of laser-induced fluorescence. The architecture of fluorescence spectroscopy system which is one of the most important parts of the nasopharyngeal carcinoma localization system and the spectrum scanning control were discussed in detail. The results show that it is not only meets the demand of spectroscopy precision and acquisition density of fluorescence spectroscopy signal but enhances the SNR as well, which provides reliable technical supports for diagnosis and localization of early nasopharyngeal carcinoma by means of drug-fluorescence spectroscopy.更多还原
