In the news and technology forums recently are such advances as: 

• 3D coronary artery fly-through images that allow cardiologists to visualize lipid or calcium deposits, immune cells that could indicate inflammation, and stent placement.  This new development is based on second generation optical coherence tomography (OCT).
  
  
• Detecting cancer in surgical margins using Raman spectroscopy.
  
  
• Locating sentinel lymph nodes during surgery using fluorescence imaging.
  
  
• Non-invasive alcohol detection based on near-infrared reflectance spectroscopy.

These bleeding-edge technologies are in late-stage development in the laboratory, undergoing clinical trials, or recently released on the market. How do they work and what else lies in store?

This presentation offers an overview of optical spectroscopy and imaging techniques, covering the above applications and more. It provides introductory information for several widely-used methods such as diffuse reflectance spectroscopy, fluorescence, Raman scattering, OCT and diffuse optical tomography (DOT); and explains how the collected information is utilized.
