This chapter considers examples of how the optical properties and architecture of a tissue affect the imaging and spectroscopy of the tissue. Examples include (1) why skin and gingiva look pink not orange, (2) adding cream to coffee to illustrate the interactive effect of absorption and scattering on observed color, (3) quantifying the blood volume of microvasculature with vessels of an apparent diameter, and (4) how optical properties affect the observed fluorescence of a tissue. Also, the chapter considers how optical properties affect photon-tissue interactions during therapeutic and surgical laser/light procedures. Examples include (1) how tissue properties affect the dosimetry of photodynamic therapy (photo-chemical interaction), (2) how tissue properties control the volume of tissue heated by a pulsed laser (photo-thermal interaction), and (3) how tissue properties influence spallation, cavitation, and explosive vaporization (photo-mechanical interactions). |
