Описание: From the early examples of what was to be called MRI, extending the te- nique to higher fields than those of less than 0. 1 T used in the first large-volume instruments was a goal, but the way there was unclear. The practical success of large superconducting magnets was a surprise, and the astonishment continued as they developed fields from 0. 3 T to 0. 6 T to 1. 5 T, and even more, up to the now common 3T systems, and a few 4T machines, and now to about 100 times the fields used in the first medium- and large-bore devices. In the early machines, low radiofrequencies of 4 MHz or so meant that RF coil designs were simple (even inexperienced undergraduates could design and build such circuits with little knowledge of more than DC electrical circuits), and the forces on gradient coils were small. The effects of magnetic susceptibility in- mogeneity in and around the object being imaged were negligible, and RF penet- tion depths were not a problem for human-scale samples. Everything began to change as higher fields and higher frequencies came into use, and the earlier idyllic simplicities began to seem quaint. The trend continued, however, driven by the increased signal-to-noise ratios and the resultant higher resolutions and speed available, and sophisticated engineering became more and more essential, not only for magnets but for gradient systems and radiofrequency transmitters and receivers, but also for better software for modeling and correcting distortions.
Описание: Magnetic resonance imaging (MRI) is a medical imaging technique used to visualize detailed internal structure of the body. This book discusses the recent developments in the field of MRI and its application to the diagnosis of human brain disorders. In addition, it reviews the newly emerging concepts and technology, based on the multi-coherence imaging (MQCI). It explains how computer packages can be used to generate images in diseased states and compare them to in vivo results. This will help improve the diagnosis of brain disorders based on the real-time events happening on atomic and molecular quantum levels. This is important since quantum-based MRI would enable clinicians to detect brain tumors at the very early stages.
Описание: Janne Marie Soetbeer determines the optimal dynamical decoupling (DD) scheme for efficient reduction of electron spin coherence loss in model systems for spin labelled biomolecules depending on their particular relaxation behavior. Extending the nth order DD scheme to double electron-electron resonance (DEER) experiments require the addition of multiple pump pulses for ? 1. Incomplete excitation of pump spin packets introduce signal artefacts which are minimized by pump pulse optimization including linear-chirp and asymmetric hyperbolic secant pulses. Prolonging the dipolar evolution time with decreased signal artefact allows to extent the measurable interspin distances in biomolecules which were otherwise not accessible due to spin echo relaxation.

Описание: While we still intend to produce a volume only if a suitable number of excellent chapters in the forefront of biological magnetic resonance are available, our philosophy is to present a pedagogical yet critical description and review of selected topics in mag- netic resonance of current interest to the community of biomedical scien- tists.

Описание: We take great pleasure in presenting Vol. IV of Biological Magnetic Resonance, a series that continues to give us pride. In this volume, we are pleased to have our first chapter on the applications of ESR to problems in medicine, written by Butterfield. Armitage and Otvos describe their extensive Cd-l13 NMR study in a chapter that should delight the spectroscopists as well as the biochemists, since the systems investigated have not yet been modeled. Kaptein presents an eloquent exposition of the principles and applications to biological systems of the photo-CIDNP technique, to which he has made pioneering contributions. Perkins tells everything one always wanted to know about the applications of ring current calculations in structural studies of biological macromolecules. Our philosophy has been, and continues to be, to present topics of current interest by authors who are active in their field, while maintaining the inter national flavor of the series. Ideally, the coverage of each topic should approach that found both in a textbook and in a reference book, rather than being a mere literature review. We are grateful to the authors for their cooperation in this respect. We continue to solicit the comments and suggestions of our readers and our colleagues, and thank those who have already responded, including the reviewers in the periodicals. Lawrence J.

Описание: Constitutes a compilation of the experiments and theories in MRI/MRS, which is the use of the stable isotope 13-C. The 13-C is used to probe the chemistry, mechanism, and function in living systems. This work discusses topics such as `Tracer Theory and the Suitability of 13-C NMR`, and `Applications of 13-C to Studies of Human Brain Metabolism`.
Описание: Here is an overview of the application of high order derivative spectrophotometry and Electron Spin Resonance spectroscopy in biology and ecology. Discussion includes the characteristics of the principle methods as well as the generation of reliable spectra.
Описание: Presents a symposium that was devoted to celestial mechanics whose aim has become the study of such `objects` as the planetary system, planetary rings, the asteroidal belt, meteor swarms, satellite systems, comet families, the zodiacal cloud, and the preplanetary nebula.

Описание: Although the nuclear magnetic resonance (NMR) phenomenon had been predicted theoretically (and to some degree demonstrated experimentally) appreciably earlier, it required the advances in electronics that took place during World War II to turn NMR into a practical technique, as demonstrated independently in 1946 by Bloch and Purcell.
