Overview of Optical and Thermal Laser-Tissue Interaction and Nomenclature
The development of a unified theory for the optical and thermal response of tissue to laser radiation is in its infancy. This book describes our current understanding of the physical events that can occur when light interacts with tissue. We present a sequence of formulations that estimate the optical and thermal responses of tissue to laser radiation. Part I considers basic tissue optics. Tissue is treated as an absorbing and scattering medium and methods are presented for calculating and measuring light propagation. Also, methods for estimating tissue optical properties from measurements of reflection and transmission are discussed. Part II concerns the thermal response of tissue owing to absorbed light, and rate reactions are presented for predicting the extent of laser-induced thermal damage. Methods for measuring temperature, thermal properties, and rate constants are detailed. Part III is devoted to examples that use the theory presented in Parts I and II to analyze various medical applications of lasers.
