Available in PDF, EPUB and Kindle. Book excerpt: 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 relationships between changes in the mean and variance of coordinate distributions of azimuths and ellipticity of polarization images of histological skin sections and the time intervals after injury. Complex differentiation of lifelong and postmortem skin injuries of biomannequins and establishment of their time intervals throughout the entire monitoring interval of changes in the mean and variance of coordinate distributions of phase shifts between orthogonal components of the amplitude of laser images of a series of corresponding histological sections are also presented in this book.

This book was released on 2020-04-08 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new diagnostic approach that utilizes complex statistical, correlation, fractal, and singular analysis of spatial distribution of the Stokes vector of scattered polarized light in different diffraction zones. The technique is able to identify changes in the distribution of optical axes and the birefringent indices of multi-layered fibrillar networks of biological tissues. The book also presents various scenarios for the formation of polarization singularities in laser speckle images of phase-inhomogeneous, multi-layered biological tissues in terms of the characteristic values of Mueller-matrix images. Moreover, in the context of potential diagnostic applications, it discusses the states of polarization singularities and their changes associated with the pathological abnormalities of the extracellular matrix of human tissues, its spatial peculiarities and structural orientation.

Download or read book Information Technology in Medical Diagnostics written by Waldemar Wójcik and published by CRC Press. This book was released on 2017-07-20 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many centuries, people have tried to learn about the state of their health. Initially, in the pre-technological period, they had to rely only on their senses. Then there were simple tools to help the human senses. The discovery of X-rays, which allowed people to look “inside” the body, turned out to be a major breakthrough. Contemporary medical diagnostics is increasingly being assisted by information technology that allows, for example, thorough image tissue analysis or pathology differentiation. They also allow very early preventive diagnostics. Influenced by information technology, “classic” diagnostic techniques change and new ones arise. Information Technology in Medical Diagnostics presents selected and extended conference papers from Polish, Ukrainian and Kazakh scientists. They address problems of the application of new methods of image processing for analysis of medical images, new methods of classification of medical data as well as new medical imaging methods. Some of the presented technologies are inspired by the functioning of living organisms. Information Technology in Medical Diagnostics is of interest not only to academics and engineers, but also to professionals involved in biomedical engineering, and seeking for solutions for issues that cannot be solved with the help of “traditional” technologies.

This book was released on 2006-10-12 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.
