Book Synopsis Ultra-Low Field Nuclear Magnetic Resonance by : Robert Kraus Jr.
Download or read book Ultra-Low Field Nuclear Magnetic Resonance written by Robert Kraus Jr. and published by Oxford University Press. This book was released on 2014-02-26 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Download or read book Compact NMR written by Bernhard Blümich and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-08-22 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.

Available in PDF, EPUB and Kindle. Book excerpt: The term magnetic resonance covers a wide range of techniques, spectroscopy, relaxation and imaging. In turn, these areas are evolving and leading to various new applications of NMR and ESR in food science and nutrition. This book is part of the continuing series of proceedings of the biennial conferences on applications of magnetic resonance to food science. As always, the aim of the book is to bring the reader up-to-date with the state-of-the-art of the subject. The speakers came from Europe, North and South America, Asia and Australasia giving a global perspective to the event. The range of the conference was broad covering sensory science, authenticity, functionality, solid state methods and new methods. Magnetic Resonance in Food Science is a global survey written by leading authorities. It provides readers with an awareness of current activity in the field and potential applications.
Book Synopsis Concomitant Gradients in Low-field NMR Studies of Restricted Diffusion by : Jason Louis Hobson
Download or read book Concomitant Gradients in Low-field NMR Studies of Restricted Diffusion written by Jason Louis Hobson and published by . This book was released on 2006 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linear magnetic field gradients are used in conventional magnetic resonance (MR) imaging in order to spatially encode and/or resolve nuclear spin distributions. These gradients are normally thought of as being unidirectional, but are always accompanied by orthogonal field components and gradients. These concomitant gradients can largely be ignored as long as the curvature they induce in magnetic field lines is small compared to inverse dimensions of the field of view. Recent attempts to acquire MR images in milliTesla magnetic fields have sparked interest in trying to understand the potential influence of concomitant field gradients. In this thesis a series of NMR experiments intended to probe diffusion of 3He gas within a restricted geometry and in very-low magnetic fields are described. Data from these experiments show clear evidence for the perturbing influence of concomitant gradients, and can be qualitatively understood in terms of a simple model that ignores diffusion.
Book Synopsis A Handbook of Nuclear Magnetic Resonance by : Ray Freeman
Download or read book A Handbook of Nuclear Magnetic Resonance written by Ray Freeman and published by Longman Scientific and Technical. This book was released on 1987 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author argues that it is not virtually impossible to cover the entire field of high-resolution NMR methodology in a single volume; there are just too many pulse sequences and variations. The guiding theme of this revised handbook is that if we can understand a few basic experiments, the rest of this giant edifice can be constructed one building block at a time, and that there is no real need for a comprehensive catalogue that lists every possible NMR experiment.

This book was released on 2010-04-07 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: 40th anniversary of "medical uses of SQUID" th It is my great pleasure and honor to invite you to the 17 International Conference on Biomagnetism – Biomag2010 held in Dubrovnik, Croatia from Sunday, March 28 through Thursday, April 1, 2010. The interdisciplinary field of biomagnetism includes dynamic and evolving SQUID-based technologies offering advanced real-time methods for noninvasive assessments of magnetic signals from the brain, heart and other organs as well as a range of modeling, mathematical and computational methods for functional source localization approaches. Excellent spatial resolution and unique, millisecond, temporal resolution of biomagnetic techniques allow insights into cortical neurodynamics and neurobiological basis of the human brain as well as assessment of heart and other organs functions in health and disease. Biomag2010 will be a great opportunity for an exchange of ideas and presentation of the latest developments in instrumentation, modeling approaches, basic and clinical biomedical studies. We are particularly proud to announce the celebration of the 40th anniversary of the first SQUID-based MCG measurements published on April 1, 1970. Since then ''medical uses of SQUID'' were dynamic and growing, including the most recent developments, in combination with a low field MRI, toward a ''direct neuronal imaging''. Dubrovnik, the host city of the Biomag2010, a jewel on the Adriatic, will be a superb and stimulating setting for both scientific and social aspects of this meeting. I am looking forward to hosting you in Dubrovnik, Croatia in spring of 2010.
Book Synopsis Analysis of NMR Spectra by : R. A. Hoffman
Download or read book Analysis of NMR Spectra written by R. A. Hoffman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance spectroscopy, which has evolved only within the last 20 years, has become one of the very important tools in chemistry and physics. The literature on its theory and application has grown immensely and a comprehensive and adequate treatment of all branches by one author, or even by several, becomes increasingly difficult. This series is planned to present articles written by experts working in various fields of nuclear magnetic resonance spectroscopy, and will contain review articles as well as progress reports and original work. Its main aim, however, is to fill a gap, existing in literature, by publishing articles written by specialists, which take the reader from the introductory stage to the latest development in the field. The editors are grateful to the authors for the time and effort spent in writing the articles, and for their invaluable cooperation. The Editors Analysis of NMR Spectra A Guide for Chemists R. A.
