Book Synopsis Optical Polarimetric Modalities for Biomedical Research by : Nirmal Mazumder
Download or read book Optical Polarimetric Modalities for Biomedical Research written by Nirmal Mazumder and published by Springer Nature. This book was released on 2023-07-25 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book provides a basic understanding of the properties of polarized light, a description of the polarization microscope, and a mathematical formalism of Mueller matrix polarimetry. The authors discuss various advanced linear and nonlinear optical techniques such as optical coherence tomography (OCT), reflectance and transmission spectroscopy, fluorescence, multiphoton excitation, second harmonic generation, Raman microscopy, and more. They explore the exciting potential of integrating polarimetry with these techniques for possible applications in different areas of biomedical research, as well as the associated challenges. Including the most recent developments on the topic, this book serves as a modern guide to polarization microscopy and advancements in its use in biomedical research.

Book Synopsis Development and Use of Polarized Light Methods to Assess Structure and Composition of Biological Tissue by : Michael F. G. Wood
Download or read book Development and Use of Polarized Light Methods to Assess Structure and Composition of Biological Tissue written by Michael F. G. Wood and published by . This book was released on 2011 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of polarized light for characterization of biological tissues has received increased attention in recent years due to the wealth of information available in the interactions of polarized light with tissue and the noninvasive nature of optical radiation. While the depolarizing effects of multiple scattering complicate the use of polarimetry in tissue, many biological constituents affect the polarization of light such as collagen, muscle fibers, and glucose. Thus, if the effects of scattering can be accounted for--or utilized in the analysis--polarized light can potentially be used as a probe of tissue status.This thesis presents advancements in the techniques for the simulation of polarized light in tissue-simulating media, and explores two biomedical applications. Previous Monte Carlo models for simulation of polarized light propagation in tissue-simulating media do not include the effects of birefringence and optical activity, two polarizing effects of useful diagnostic potential. To overcome this limitation, our model was extended to include both these effects simultaneously, and then experimentally validated using a novel polarization phantom system. The use of polarized light for characterization of the myocardium, and specifically towards monitoring stem cell regenerative treatments of myocardial infarction, was investigated experimentally as a novel application for polarimetry. The potential for this technique is based on the changes in myocardial structure that occur with infarction and subsequent regeneration, and the associated changes in tissue birefringence. The use of polarized light for noninvasive tissue analyte monitoring, particularly glucose, was also investigated based on the optical activity exhibited by many tissue analytes due to their chiral structure. In this study, a novel combined optical polarization and intensity approach was developed and tested on Monte Carlo simulated data. The studies presented in thesis introduce new methods for polarization simulation and analysis in biological tissue and demonstrate potential for polarimetry in monitoring myocardial regeneration and noninvasive measurements of tissue analytes.

Book Synopsis Optical Polarization in Biomedical Applications by : Valery V. Tuchin
Download or read book Optical Polarization in Biomedical Applications written by Valery V. Tuchin and published by Springer Science & Business Media. This book was released on 2006-10-12 with total page 281 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. 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.

Book Synopsis Laser Applications in Medicine and Biology by : M.L. Wolbarsht
Download or read book Laser Applications in Medicine and Biology written by M.L. Wolbarsht and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability,and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses.
