Abstract: A method for imaging a tissue includes collecting a light signal from at least part of said tissue, using a fiber optic probe for fluorescence imaging, wherein the fiber optic probe comprises a plurality of optic fibers, and wherein a distal tip of the fiber optic probe is placed at a distance from said tissue, said imaging being made confocal at a proximal tip of said fiber optic probe. A fluorescence imaging system includes an endoscope equipped with a working channel, in which a fiber optic probe has been inserted, wherein the fiber optic probe is movable between a retracted position and at least one position of extension, said fiber optic probe comprising a plurality of optic fibers for performing imaging of a tissue, said imaging being confocal via a processor located at a proximal tip of said fiber optic probe.
