摘要: A method for laser induced fluorescence of tissue in which laser radiation is used to illuminate and induce fluorescence in the tissue under study to determine the chemical composition or pathologic condition of tissue. The laser radiation and the retrieved fluorescing radiation can be conveyed through a catheter using an array of optical fiber. The fluorescence spectrum of the tissue can be displayed and analyzed to obtain information regarding the chemical composition and medical condition of the tissue inside the human body.

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.
