Abstract
The present invention relates to systems and methods employed in the use of spectroscopy in the diagnosis of tissue. More particularly, it relates to the use of surface contact and needle probe devices having one or more optical fibers used to direct laser radiation onto tissue to be diagnosed, collecting radiation subsequently emitted by the tissue and delivering that radiation to a system for spectral analysis.
