Abstract
The present invention relates to a fluorescence endoscope imaging system. The system uses first and second light sources to provide fluorescence and reflectance images of tissue being examined. The imaging system also includes an electronic controller that actuates the illumination of the system by switching current through the first light source between a first illumination level and a second illumination level such that the tissue is illuminated at the first or second illumination level. An imaging device mounted at the distal end of the device is used to collect both images.
