Claim 0:
1. A near-infrared fluorescence endoscopic dental imaging system, comprising:
an endoscope forming a plurality of lumens therein;
a spectrometer optically coupled to a first lumen of the endoscope;
a near-infrared camera optically coupled to a second lumen of the endoscope;
a data processor in communication with the spectrometer and the near-infrared camera;
a bifurcated fiber disposed in the second lumen, the bifurcated fiber having a first channel optically coupled to the spectrometer and a second channel optically coupled to a near-infrared illumination source; and
a display system in communication with the data processor,
wherein the near-infrared camera is configured to capture a near-infrared two-dimensional dental image of a specimen having indocyanine green (ICG) and transmit the near-infrared two-dimensional dental image to the data processor,
wherein the spectrometer is configured to capture fluorescent light from the specimen having the indocyanine green (ICG) and provide a spectroscopic signal to the data processor,
wherein the display system is configured to communicate with the data processor to receive the near-infrared two-dimensional dental image and the spectroscopic signal and to display a two-dimensional dental image of the specimen,
wherein the near-infrared two-dimensional dental image of the specimen captured by the near-infrared camera provides an overview of a wide angle imaging field of the specimen and the fluorescent light from the specimen captured by the spectrometer provides a wavelength-resolved spectroscopy of a selected imaged area within the near-infrared two-dimensional dental image, and
wherein the near-infrared camera has a spatial resolution less than 100 mm in near-infrared.
