of exposure. Note that this effect may influence both the efficiency and the safety
of the procedure, because it violates the local heating.
Thus, the optimization of the laser emitter for selective heating of multicomponent media is an ambiguous problem.
For these purposes various mathematical models have been developed, which
are usually designed to solve a specific task. In most cases, the problem of choice
of the laser source and its performance are decided on the basis of the absorption
and relaxation times of the objects (media). Modeling of this kind is usually
designed to solve the problem of optimizing the parameters of the laser transmitter
and evaluate the results obtained under the influence of the preselected laser on the
biological environment. In order to correctly construct a mathematical model that
describes the interaction of laser radiation with tissue, it is first and foremost a
establish good understanding of the structure of biological tissues, their optical and
thermal properties, as well as the main effects in the propagation of radiation in
biological tissues.
The monograph discusses problems related to the study of mechanisms of
interaction of laser radiation with biological tissues, the study of effects of laser
interaction with biological tissues methods of the asymptotic theory of diffraction,
and computer modeling. By virtue of models described in the monograph, on the
basis of result of influence of laser biological tissue under certain conditions, can be
consistently changed to input characteristics to produce an optimization of the
spectral and energy parameters of laser emitters to achieve the desired effect in each
case.
The book presents the original results of theoretical studies of electromagnetic
waves in media-simulating biological-layered structure. Concepts and methods for
studying the laser radiation interaction with multicomponent heterogeneous tissue
with a complex structure of the asymptotic theory of diffraction methods are presented. These methods can serve as the basis for creating a software for the
biomedical diagnostics.
The monograph is addressed to researchers and specialists in biomedical physics
interested in the development and application of laser and optical diagnostic
methods in medical research.
The monograph consists of ten chapters.
In Chap. 1, we consider the structure and optical properties of biological tissues,
blood, and human skin.
In Chap. 2, we expand methods of light scattering for the quantitative study
of the optical characteristics of the tissue, and the results of theoretical and
experimental studies of photon transport in biological tissues.
In Chap. 3, we describe the optical characteristics, namely, dispersion and
absorption spectra of an ensemble of spherical particles randomly oriented inside an
optical cavity. The study is based on the self-consistent matching of new data from
the inhomogeneous optical cavity with data from the scattering of an ensemble of
spherical particles of different size, randomly oriented in free space.
