Book Description
Fundamentals of In Vivo Magnetic Resonance Authoritative reference explaining why and how the most important, radiation-free technique for elucidating tissue properties in the body works In Vivo Magnetic Resonance helps readers develop an understanding of the fundamental physical processes that take place inside the body that can be probed by magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS), uniquely bridging the gap between the physics of magnetic resonance (MR) image formation and the in vivo processes that influence the detected signals, thereby equipping the reader with the mathematical tools essential to study the spin interactions leading to various contrast mechanisms. With a focus on clinical relevance, this book equips readers with practical knowledge that can be directly applied in medical settings, enabling informed decision-making and advancements in the field of medical imaging. The material arises from the lecture notes for a Stanford University Department of Radiology course taught for over 15 years. Aided by clever illustrations, the book takes a step-by-step approach to explain complex concepts in a comprehensible manner. Readers can test their understanding by working on approximately 60 sample problems. Written by two highly qualified authors with significant experience in the field, In Vivo Magnetic Resonance includes information on: The fundamental imaging equations of MRI Quantum elements of magnetic resonance, including linear vector spaces, Dirac notation, Hilbert Space, Liouville Space, and associated mathematical concepts Nuclear spins, covering external and internal interactions, chemical shifts, dipolar coupling, J-coupling, the spin density operator, and the product operator formalism In vivo MR spectroscopy methods MR relaxation theory and the underlying sources of image contrast accessible via modern clinical MR imaging techniques With comprehensive yet accessible coverage of the subject and a wealth of learning resources included throughout, In Vivo Magnetic Resonance is an ideal text for graduate students in the fields of physics, biophysics, biomedical physics, and materials science, along with lecturers seeking classroom aids.

Book Description
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.

Book Description
MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.

Book Description
qMRI is a rapidly evolving scientific field of high current interest because it has the potential of radically changing the clinical and research practices of magnetic resonance imaging (MRI). This focuses solely on the theoretical aspects of qMRI, which are treated and analyzed at three different spatial scales, specifically: i) the quantum physics scale of individual spins; ii) the semi-classical physics scale of spin packets; and iii) the imaging scale of voxels. Topics are presented paying particular attention to theoretical unification and mathematical uniformity.

Book Description
The first edition of this book was written in 1961 when I was Morris Loeb Lecturer in Physics at Harvard. In the preface I wrote: "The problem faced by a beginner today is enormous. If he attempts to read a current article, he often finds that the first paragraph refers to an earlier paper on which the whole article is based, and with which the author naturally assumes familiarity. That reference in turn is based on another, so the hapless student finds himself in a seemingly endless retreat. I have felt that graduate students or others beginning research in magnetic resonance needed a book which really went into the details of calculations, yet was aimed at the beginner rather than the expert. " The original goal was to treat only those topics that are essential to an understanding of the literature. Thus the goal was to be selective rather than comprehensive. With the passage of time, important new concepts were becoming so all-pervasive that I felt the need to add them. That led to the second edition, which Dr. Lotsch, Physics Editor of Springer-Verlag, encouraged me to write and which helped launch the Springer Series in Solid-State Sciences. Now, ten years later, that book (and its 1980 revised printing) is no longer available. Meanwhile, workers in magnetic resonance have continued to develop startling new insights.
