AORTA ABLATION AND FLUORESCENCE SPECTRUM INDUCED BY ULTRAVIOLET LASER
紫外激光消融主动脉斑块和感生荧光光谱观测

A XeCl excimer laser was used to irradiate normal and atherosclerotic plaque tissue of aorta vessel. The tissue formed a crater by laser ablation. The depth and volume of the crater versus irradiated time show line-logarithm relation. Fluorescence spectra induced by 308nm ultraviolet laser appear two fluorescence peaks at visible region. The ratio of the intensity of these two peaks can be used as criterion for normal or plaque tissue.
