"This lavishly illustrated book uses high-quality images to present a practical guide to the physics of magnetic resonance. Written by internationally renowned authors, the book places an emphasis on learning visually through images of real cases rather than through mathematical equations and provides the fundamental information needed to achieve the best images in everyday clinical practice. This edition features new images and incorporates information on the latest technical advances in the field, discussing such important topics as 3 T MR, specific absorption rate (SAR), arterial spin labeling, continuous moving-table MR, and time-resolved contrast-enhanced MR angiography." "This book is a valuable reference for radiologists and an excellent resource for residents preparing for board examinations. It is also ideal for MR technologists and students seeking to fully understand the basic principles underlying this important diagnostic tool."--BOOK JACKET.

The Physics and Mathematics of MRI by Richard Ansorge,Martin Graves Pdf

Magnetic Resonance Imaging is a very important clinical imaging tool. It combines different fields of physics and engineering in a uniquely complex way. MRI is also surprisingly versatile, 'pulse sequences' can be designed to yield many different types of contrast. This versatility is unique to MRI. This short book gives both an in depth account of the methods used for the operation and construction of modern MRI systems and also the principles of sequence design and many examples of applications. An important additional feature of this book is the detailed discussion of the mathematical principles used in building optimal MRI systems and for sequence design. The mathematical discussion is very suitable for undergraduates attending medical physics courses. It is also more complete than usually found in alternative books for physical scientists or more clinically orientated works.
