Nuclear magnetic resonance is now widely used in hospitals and research laboratories worldwide for medical purposes. Biomedical Magnetic Resonance Imaging is the first book to concentrate on how the instrumentation involved works rather than on the applications of the technique. In order to help the reader fully understand how an NMR imaging or spectroscopy system works the book takes an in-depth look at the principles behind the different components of the machine. Starting with a short history of the developments of nuclear magnetic resonance, the authors go on to describe all the different areas of instrumentation, such as the receiver and the magnet. A full explanation of the electronics and computer hardware and software appears for the first time in book form, completing this thorough view of an NMR system. Each chapter builds from a basic to a more sophisticated level of understanding and numerous illustrations help the reader to grasp the concepts. For the most part, mathematical descriptions appear at the ends of chapters, to place the emphasis of the book on the understanding of underlying principles. Biomedical Magnetic Resonance Imaging will be invaluable to all medical physicists, technicians, researchers and engineers working with NMR, containing as it does both theoretical and practical data to enable users to get the most out of their machines.
