Overview

MRI: Essentials for Innovative Technologies describes novel methods to improve magnetic resonance imaging (MRI) beyond its current limitations. It proposes smart encoding methods and acquisition sequences to deal with frequency displacement due to residual static magnetic field inhomogeneity, motion, and undersampling. Requiring few or no hardware modifications, these speculative methods offer building blocks that can be combined and refined to overcome barriers to more advanced MRI applications, such as real-time imaging and open systems. After a concise review of basic mathematical tools and the physics of MRI, the book describes the severe artifacts produced by conventional MRI techniques. It first tackles magnetic field inhomogeneities, outlining conventional solutions as well as a completely different approach based on time-varying gradients and temporal frequency variation coding (acceleration). The book then proposes two innovative acquisition methods for reducing acquisition time, motion, and undersampling artifacts: adaptive acquisition and compressed sensing. The concluding chapter lays out the author’s predictions for the future of MRI. For some of the proposed solutions, this is the first time the reported results have been published. Where experimental data is preliminary or unavailable, the book presents only numerical solutions. Offering insight into emerging MRI techniques, this book provides readers with specialized knowledge to help them design better acquisition sequences and select appropriate correction methods. The author’s proceeds from the sale of this book will be entirely donated to Bambin Gesù Children’s Hospital in Rome.

MRI Essentials for Innovative Technologies describes novel methods to improve MRI beyond its current limitations and combines rigorous development of mathematical concepts with descriptive presentations of the emerging MRI techniques. ...Although this book covers a specialized area of MRI and the emerging technologies around this imaging modality, the text is comprehensible to most readers. -IEEE Pulse Magazine, April 2014 The deep physical insight into the relationship between spin dynamics and gradient field modulation expressed in this book paves the way to a completely new family of pulse sequences that may represent a new line of development for MRI. As a whole, this excellent book should be found on the bookshelves of all those specializing in the field of magnetic resonance. -From the Foreword by Antonello Sotgiu, Professor and Chairman, Department of Health Sciences, University of L'Aquila, Italy [This book] is complete, readable and usable both for research and for specialized learning purposes in areas of advanced MRI imaging techniques. Dr. Placidi indicates a path useful to both physicists and engineers for implementation, and to radiologists and clinicians in thinking of possible new ways to apply the suggested methods. -From the Foreword by Roberto Passariello, MD, Professor and Chairman, Department of Radiological Sciences, Policlinico Umberto I, Sapienza University of Rome, Italy
