Ultraviolet Laser-Induced Fluorescence Spectroscopy Diagnosis of Human Stomach Malignant Tissues

To evaluate the potential of laser-induced autofluorescence spectroscopy for the detection of premalignant lesions of human stomach, fluorescence properties of stomach tissues have been investigated in vitro and in vivo. A specially made optical fibre probe and the multichannel fluorescence collection system have been used successfully in our research.
