Sunday Evening: |
Origins of Tissue Optical Properties and their Role in Light Transport |
Chair: Steven Jacques, Oregon Medical Laser Center
Summary: Light scattering depends on a tissue's ultrastructual composition and absorption depends on a tissue's chemical composition. Together absorption and scattering determine how light transports through the tissue. This session summarizes the current understanding of these relationships.

Optical Spectroscopy for Detection and Monitoring Neoplasia |
Chair: Rebecca Richards-Kortum, University of Texas at Austin
Summary: This session will highlight recent efforts to develop and test optical spectroscopy to identify and monitor neoplastic lesions in situ. New developments in the clinical application of reflectance, fluorescence and Raman spectroscopies will be considered. Special emphasis will be given to models to understand the morphologic and biochemical basis of spectroscopic signatures of neoplasia.
