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. An imaging device mounted at the distal end of the device is used to collect both images.
Claims32
A method of fluorescence imaging comprising:
- providing an endoscope having an optical guide that is optically coupled to a first light source and a second laser light source, the endoscope having an image sensor at a distal end;
- collecting a reflectance image with the image sensor and generating a reference;
- collecting a fluorescence image with the image sensor;
- and
- processing the fluorescence image with the reference to provide a processed fluorescence image.
