Paper Abstract

Laser-induced fluorescence (LIF) is a promising method for pre-malignant lung tissue diagnosis and it is very important to find effective common diagnosis criteria needed by clinic. In this paper, some differences between normal and cancer lung tissue, such as I444/I414 ratio, main peak width, and integral area were exhibited and discussed. By using the fourth harmonic at 266nm of a Q-switched Nd:YAG laser as an excitation source, Optical Multi-channel Analyzer (OMA) as a detector, laser-induced fluorescence spectra of normal and cancer lung tissue in-vitro were measured. According to the spectra characteristics, three independent diagnosis criteria were obtained and analyzed. The total specificity is above 95%.
