Relaxation in Magnetic Resonance by Charles P. Jr. Poole Pdf

Relaxation in Magnetic Resonance contains a series of lecture notes for a special topics course at the University of South Carolina in 1967. This book contains 21 chapters that summarize the main theoretical formulations and experimental results of magnetic resonance relaxation phenomena in several physical systems. This text deals first with the various methods in determining the relaxation behavior of the macroscopic spin system, such as Bloch equations, saturation methods, and transient resonant absorption. The subsequent chapters discuss the homogeneous and inhomogeneous resonant lines in solids and liquids and the significance of the Kubo-Tomita and Redfield theories in magnetic resonance. This book then considers the background research on electron spin resonance and relaxation in ionic solids. The concluding chapters explore the acoustic absorption coefficient and dielectric constant calculation; the relaxation processes in paramagnetic substance; and the characteristics of Mössbauer spectra and their application in magnetic relaxation. This book will be useful to both graduate students embarking upon thesis problems in relaxation and more advanced workers who seek an overall summary of the status of the field, as well as to physicists and chemists.

The Theory of Nuclear Magnetic Relaxation in Liquids by James McConnell Pdf

This book provides a complete exposition of the theory of nuclear magnetic relaxation caused by the thermal motion of the molecule containing the relaxing nucleus. The author begins by defining the physical quantities encountered in nuclear magnetic resonance studies and surveying pioneering investigations in the field. Nuclear magnetic relaxation by scalar, dipolar, quadrupolar and spin-rotational interactions and by anisotropic chemical shift are then examined in detail. Relaxation rates are expressed in terms of spectral densities, and the values of the spectral densities for various molecular shapes are calculated by random walk or Brownian motion dynamics. The text should be within the grasp of readers who have taken undergraduate courses in electromagnetic theory and in classical and quantum mechanics, although topics in these fields of particular relevance are to be found in appendices. This book will be of value to postgraduate students and research workers using n.m.r. in physics and physical chemistry departments, and by scientists in industrial and medical research.

Nuclear Spin Relaxation in Liquids by Jozef Kowalewski,Lena Maler Pdf

Nuclear magnetic resonance (NMR) is widely used across many fields of science because of the rich data it produces, and some of the most valuable data come from studies of nuclear spin relaxation in solution. The first edition of this book, published more than a decade ago, provided an accessible and cohesive treatment of the field. The present second edition is a significant update, covering important new developments in recent years. Collecting relaxation theory, experimental techniques, and illustrative applications into a single volume, this book clarifies the nature of the phenomenon, shows how to study it and explains why such studies are worthwhile. Coverage ranges from basic to rigorous theory and from simple to sophisticated experimental methods. Topics include cross-relaxation, multispin phenomena, relaxation studies of molecular dynamics and structure and special topics such as relaxation in systems with quadrupolar nuclei, in paramagnetic systems and in long-living spin states. Avoiding overly demanding mathematics, the authors explain spin relaxation in a manner that anyone with a familiarity with NMR can follow. The focus is on illustrating and explaining the physical nature of relaxation phenomena. Nuclear Spin Relaxation in Liquids: Theory, Experiments and Applications, 2nd edition, provides useful supplementary reading for graduate students and is a valuable reference for NMR spectroscopists, whether in chemistry, physics or biochemistry.

Fast Quantitative Magnetic Resonance Imaging by Guido Buonincontri,Joshua Kaggie,Martin Graves Pdf

Among medical imaging modalities, magnetic resonance imaging (MRI) stands out for its excellent soft-tissue contrast, anatomical detail, and high sensitivity for disease detection. However, as proven by the continuous and vast effort to develop new MRI techniques, limitations and open challenges remain. The primary source of contrast in MRI images are the various relaxation parameters associated with the nuclear magnetic resonance (NMR) phenomena upon which MRI is based. Although it is possible to quantify these relaxation parameters (qMRI) they are rarely used in the clinic, and radiological interpretation of images is primarily based upon images that are relaxation time weighted. The clinical adoption of qMRI is mainly limited by the long acquisition times required to quantify each relaxation parameter as well as questions around their accuracy and reliability. More specifically, the main limitations of qMRI methods have been the difficulty in dealing with the high inter-parameter correlations and a high sensitivity to MRI system imperfections. Recently, new methods for rapid qMRI have been proposed. The multi-parametric models at the heart of these techniques have the main advantage of accounting for the correlations between the parameters of interest as well as system imperfections. This holistic view on the MR signal makes it possible to regress many individual parameters at once, potentially with a higher accuracy. Novel, accurate techniques promise a fast estimation of relevant MRI quantities, including but not limited to longitudinal (T1) and transverse (T2) relaxation times. Among these emerging methods, MR Fingerprinting (MRF), synthetic MR (syMRI or MAGIC), and T1‒T2 Shuffling are making their way into the clinical world at a very fast pace. However, the main underlying assumptions and algorithms used are sometimes different from those found in the conventional MRI literature, and can be elusive at times. In this book, we take the opportunity to study and describe the main assumptions, theoretical background, and methods that are the basis of these emerging techniques. Quantitative transient state imaging provides an incredible, transformative opportunity for MRI. There is huge potential to further extend the physics, in conjunction with the underlying physiology, toward a better theoretical description of the underlying models, their application, and evaluation to improve the assessment of disease and treatment efficacy.

Nuclear Magnetic Resonance and Relaxation by Brian Cowan Pdf

This book provides an introduction to the general principles of nuclear magnetic resonance and relaxation, concentrating on simple models and their application. It includes an introduction to the ideas and applications of nuclear magnetic resonance and emphasizes the concepts of relaxation and the time domain. Some relatively advanced topics are treated, but the approach is graduated and all points of potential difficulty are carefully explained. An introductory classical discussion of relaxation is followed by a quantum-mechanical treatment. A selection of case studies is considered in depth, providing applications of the ideas developed in the text. There are a number of appendixes, including one on random functions. This treatment of one of the most important experimental techniques in modern science will be of great value to final-year undergraduates, graduate students and researchers using nuclear magnetic resonance, particularly physicists, and especially those involved in the study of condensed matter physics.
