Laser Polarimetry of Biological Tissues

This book highlights the results of numerical computer-aided smart methods as part of a comprehensive statistical, correlated, and fractal analysis of laser polarimetry. It includes a comprehensive approach to differentiation of lifelong or postmortem origin of injuries and determination of their antiquity based on the analysis of statistical and spatiotemporal frequency evolution of photometric, polarization, and phase parameters of laser images of histological sections of the skin of biomannequins. It discusses the relationship between the coordinate distributions of the intensity of laser images from skin tissues of biomannequins and the nature of its damage. It presents the analysis of r...

Phase Mapping of Human Biological Tissues

This book presents numerical computer-aided smart-methods as part of a comprehensive statistical, correlation and fractal analysis of laser polarimetry data. It highlights relationships between polarization (azimuth distributions, polarization ellipticities, Stokes vector parameters, Mueller matrix elements) parameters of laser images of biological tissues of a human corpse in different spectral ranges and temporal dynamics of their postmortem morphological changes. The book discusses the effectiveness of correlation analysis of two-dimensional distributions of polarization inhomogeneous images of histological sections of the main types of biological tissues in determining the time of death....

Mueller-Matrix Tomography of Biological Tissues and Fluids

This book presents experimental investigations and digital image processing, highlighting the interaction of polarized radiation with phase-inhomogeneous and optically anisotropic biological layers. The promising and efficient use of vector-parametric description of the formation of polarization-inhomogeneous object fields is noted. Applications of a set of Mueller-matrix polarimetry methods are highlighted. The book includes- structural and logical scheme of multi-parameter (singular, interference and layer-by-layer Stokes-polarimetric), polarization-correlation study of the structure of distributions of the number of singularities, maps of local contrast of interference distributions and layer-by-layer maps of microscopic polarization azimuth and ellipticity; determination of relationships between changes in the magnitude of statistical parameters characterizing polarization-correlation distributions and pathology of prostate tumors.

Correlation and Autofluorescence Microscopy in Forensics Medicine: Time of Death Detection Using Polycrystalline Cerebrospinal Fluid Films

This book highlights the first systematic synthesis of various research approaches in forensic medical diagnosis of the morphological and polycrystalline structure of human biological tissues and biological fluids. One of the global challenges in such diagnosis is the assessment of actual time of death. The relevance and objectivity of such studies are given by the innovative use of complex multifunctional methods using lasers and Mueller-matrix polarimetry, which is presented in this book. As a result, within the framework of the statistical, correlation and fractal approaches, diagnostic relationships were established between the time parameters of the transformation of the topographic structure of polarization-inhomogeneous microscopic images of biological preparations and necrotic changes in the morphological structure of biological tissues of the deceased. On this foundation, new forensic medicine criteria have been developed for objective determination of time of death.

Optical Anisotropy of Biological Polycrystalline Networks

This book highlights the analysis of new azimuth-independent methods of Stokes polarimetry and Mueller-matrix reconstruction of distributions of optical anisotropy parameters using spatial-frequency filtering of manifestations of phase (linear and circular birefringence) and amplitude (linear and circular dichroism) anisotropy for diagnosing changes in the orientational-phase structure of fibrillar networks of histological sections of biological tissues and polycrystalline films of biological fluids.

Multi-parameter Mueller Matrix Microscopy for the Expert Assessment of Acute Myocardium Ischemia

This book provides an essential overview of the basic principles of imaging modalities, accompanied by examples of their applications in modern clinical and associated pre-clinical studies. The monograph is based on the original results of investigation of the efficiency use of laser light and Mueller-matrix polarimetry approach for assessment of myocardial tissues towards confirmation the cause of death. A morphological analysis of necrotic changes in the myocardial tissue of patients that died due to heart attack, coronary heart disease and acute coronary insufficiency was carried out and the data and histological sections of the myocardium inspected utilizing Mueller-matrix mapping of tis...

Optical Polarimetric Modalities for Biomedical Research

This book focuses on polarization microscopy, a powerful optical tool used to study anisotropic properties in biomolecules, and its enormous potential to improve diagnostic tools for various biomedical research. The interaction of polarized light with normal and abnormal regions of tissue reveals structural information associated with its pathological condition. Diagnosis using conventional microscopy can be time-consuming, as pathologists require an hour to freeze and stain tissue slices from suspected patients. In comparison, polarization microscopy more quickly distinguishes abnormal tissue and provides better microstructural information of samples, even in the absence of staining. This b...

Optical Polarization in Biomedical Applications

Optical Polarization in Biomedical Applications introduces key developments in optical polarization methods for quantitative studies of tissues, while presenting the theory of polarization transfer in a random medium as a basis for the quantitative description of polarized light interaction with tissues. This theory uses the modified transfer equation for Stokes parameters and predicts the polarization structure of multiple scattered optical fields. The backscattering polarization matrices (Jones matrix and Mueller matrix) important for noninvasive medical diagnostic are introduced. The text also describes a number of diagnostic techniques such as CW polarization imaging and spectroscopy, polarization microscopy and cytometry. As a new tool for medical diagnosis, optical coherent polarization tomography is analyzed. The monograph also covers a range of biomedical applications, among them cataract and glaucoma diagnostics, glucose sensing, and the detection of bacteria.

Greece’s Ostpolitik

The book examines the rapprochement between Greece and Eastern Europe during the Cold War. ''Ostpolitik'', which translates to ‘‘Opening to the East’’ is used to describe the policy of conducting affairs with the Soviet Bloc. Using primary sources from Greece, Eastern European States, Cyprus, NATO, the United States, Germany and United Kingdom, this book provides historical and foreign policy analysis of a tumultuous period in the Eastern Mediterranean. The book first illustrates Greece's position in the Cold War confrontation before moving to more detailed analysis of the Eastern Bloc's policies towards Greece and Cyprus with an emphasis in the harmonious relationship between the Gr...
