Paper Abstract

The paper presents a new method for malignant tumor diagnosis by rapidly detecting the argon laser induced autofluorescence spectra. The diagnostic system consists of an argon laser and an optical multichannel analyzer. With a special processing program, the spectral signal acquisition and the specific index Is/I analyzing could be done simultaneously in real time by a micro-computer. The system can not only be used for spectral measurement of separate points individually, but applied to continuous IsI scanning of entire suspicious areas as well. By this technique, the Lewis lung tumors less than 1 mm were identified in in-vivo experiments, and the human cancer of 2 mm was found in clinical detections.
