Abstract

A fluorescence imaging system was constructed to take images of oral cavity for oral cancer and precancer detection. Being applied at oral cavity for one hour, ALA would be metabolized by cells to be PpIX, which emitted red fluorescence (630nm) while illuminated by violet light {wavelength 410nm). The results show that explicit red color was presented at those cancerous / precacnerous areas on the image. The abnormal area could be easily identified. This imaging technique is potential for oral cancer / precancer diagnosis.
