Abstract
We report on the development of a fluorescence imaging system for early detection of cancers in the GI tract. The system comprises a modified light source, endoscope, camera and associated image processing software. The photosensitizing agent is 5-aminolaevulinic acid, metabolized within the tumor to form protoporphyrin IX that absorbs strongly between 390-410 nm and fluoresces at 635 nm.
