    摘要: The present invention relates to a method and apparatus for diagnosing the condition of gastrointestinal tissue. The method and apparatus excite fluorophores within a portion of gastrointestinal tissue with a laser to cause the fluorophores to emit fluorescent radiation. The presence of abnormal tissue is then determined by detecting the radiation emitted by the excited fluorophores and comparing the emitted radiation to a reference emission for fluorophores within normal tissue at predetermined wavelengths.
