This book presents a selection of papers, written by Nicolaas Bloembergen and his associates during the years 1946-1962, on the subjects of nuclear magnetic relaxation, paramagnetic relaxation and masers, and magnetic resonance spectroscopy of solids. The volume begins with autobiographical notes to provide a personal historical background. Each paper is preceded by commentary with additional information regarding the early development of magnetic resonance in condensed matter. A reproduction of his Ph.D. thesis, ?Nuclear Magnetic Relaxation?, Leiden, 1948, is included in this volume.

TWENTY-FIVE years ago in Russia, Zavoisky made the first experimen tal observation of electron spin resonances; and a year later Purcell, Torrey and Pound at Harvard and Bloch, Hansen and Packard at Stanford ('The Harvard of the West') observed nuclear magnetic resonances for the first time. In both cases (ESR and NMR) the phenomena had been previously predicted, and Gorter - surely one of the most unlucky experimenters of our time - had made his noble attempts to detect magnetic resonances. Purcell et aZ. , having beaten their radar swords into scientific ploughshares, used a re 3 sonant coaxial cavity, filled the inductive part with 850 cm of paraffin, and produced a resonance with a signal-to-noise ratio of 20. They predicted that the sensitivity could be increased several hundred-fold and foresaw applications in determining magnetic mo ments, investigating spin-lattice coupling and measuring magnetic fields. Their letter reached the editor of Phys. Rev. on Christmas Eve 1945, and the basis of NMR in the solid state was laid. Bloch et aZ. , fortunately working independently, established the entirely different, crossed-coil approach to the observation of NMR in a water sample, which they doped with paramagnetic ions to reduce the relaxation times. They had laid the foundation of liquid-state NMR. Their letter to Phys. Rev. was received on 29 January 1946.

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.

This biography is a personal portrait of one of the best-known Dutch physicists, Nicolaas Bloembergen. Born in 1920 in Dordrecht, Bloembergen studied physics in Utrecht, leaving after World War II for the United States, where he became an American citizen in 1958. At Harvard University, he pioneered nuclear magnetic resonance (NMR, used in chemistry and biology for structure identification; moreover leading to MRI), laser theory and nonlinear optics. In 1978 he was awarded the Lorentz Medal for his contribution to the theory of nonlinear optics (used in fiber optics), and in 1981 he received the Nobel Prize for physics, along with Arthur Schawlow and Kai Siegbahn. The book is based on numerous conversations with Nicolaas Bloembergen himself, his wife Deli Brink, his family, and colleagues in science. It describes his childhood and study in Bilthoven and Utrecht, the first postwar years at Harvard, the discoveries of masers and lasers, and the award of the Nobel Prize. It also delves into Bloembergen's involvement in American politics, particularly his role in Ronald Reagan's controversial "Star Wars" program.

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.

The foundation for understanding the function and dynamics of biological systems is not only knowledge of their structure, but the new methodologies and applications used to determine that structure. This volume in Biological Magnetic Resonance emphasizes the methods that involve Ultra High Field Magnetic Resonance Imaging. It will interest researchers working in the field of imaging.

Functional Magnetic Resonance Imaging (fMRI) is now a standard tool for mapping activation patterns in the human brain. This highly interdisciplinary field involves neuroscientists and physicists as well as clinicians who need to understand the rapidly increasing range, flexibility and sophistication of the techniques. In this book, Richard Buxton, a leading authority on fMRI, provides an invaluable introduction for this readership to how fMRI works, from basic principles and the underlying physics and physiology, to newer techniques such as arterial spin labeling and diffusion tensor imaging.
