Abstract
The present invention relates to a spectroscopic imaging system using autofluorescence and reflectance images to diagnose tissue. A preferred embodiment of the invention uses a plurality of light sources to illuminate a tissue region to provide the fluorescence and reflectance images, respectively.
Claims52
A spectroscopic imaging system comprising:
- a light source;
- an imaging detector that detects fluorescent and reflectance data to provide an image of tissue;
- and
- a data processor that processes the image to diagnose the tissue.
The system of claim 19 wherein the detector comprises at least a 500×500 array of pixel elements that form an image of an area of tissue have at least 500×500 image pixels.
A method spectroscopic imaging comprising:
- illuminating a material with a light source;
- detecting light with an imaging detector that detects fluorescent and reflectance data to provide an image of the material;
- and
- processing the data with an data processor that processes the image to characterize the material.
A system for angular gating of light scattering spectroscopy comprising:
- illuminating a material with light from a light source;
- detecting light with a detector that detects light scattered from the material at different azimuthal angles to provide spectral data;
- and
- a data processor that processes the spectral data to characterize the material.
