Abstract
Epifluorescence stereoscope system and angioscope analyzer system for photodiagnosis with a photosensitizer (mono-L-aspartyl chlorin e6: NPe6) assembled diode laser system. Using epifluorescence stereoscopesystem, fluorescence image pattern of NPe6 that accumulated in the submucosal tumor on esophagus. Atheroscleroticlesions on coronary artery were measured for the photodiagnosis with a Npe6 using an angioscopeanalyzer system.
