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.

MRI with hyperpolarized carbon-13 agents is a powerful emerging imaging modality that can measure real-time metabolism in cells, animals, and humans. It uses endogenous, non-toxic contrast agents that a hyperpolarized, resulting in up to 100,000-fold increases in sensitivity. This technique uses no ionizing radiation, and is being applied in a range of human trials. It's primary use is for metabolic imaging, but it can also measure perfusion, pH, and necrosis. Hyperpolarized Carbon-13 Magnetic Resonance Imaging and Spectroscopy is designed to be a one stop shop for understanding hyperpolarized 13C MRI. This book explains the principles of this imaging modality, the requirements for performing studies, shows how to interpret the results, and gives an overview of current biomedical applications. It is suitable for engineers, scientists and clinicians in radiology and biomedical imaging who want to understand this technology. - Presents the physics and hardware of dissolution dynamic nuclear polarization - Explains the behaviour of hyperpolarized carbon-13 agents and how to image them - Detailed guidance on experimental design and data interpretation - Identifies promising and potential applications of hyperpolarized carbon-13 MR

Nuclear magnetic resonance imaging is one of several new experimental tech niques which have rec{ ,tly been applied to food systems. NMR in general and nuclear magnetic resonance imaging are powerful probes of the microscopic and macroscopic changes occurring in foods during processing, storage and utilization. The training that food scientists and food engineers have received in the past has often omitted specific courses in physical chemistry that form the theoretical and practical foundation necessary to fully utilized magnetic resonance experimental techniques. The goal of Magnetic Resonance Imaging in Foods is to introduce food scien tists and food engineers to magnetic resonance imaging and provide a basis for further study. As such the book begins with two chapters of an introductory nature. The first chapter introduces magnetic resonance phenomena, NMR in general, and MRI in detail. Particular emphasis is given to the limitations and typical ranges available for studying particular phenomena, for example, the range of diffusivities that can be studied using commercial grade NMR equipment. Chapter 2 gives a brief introduction to the classical physical model of NMR first introduced by Felix Bloch in 1946 and aspects important to the interpretation of MRI data. This chapter is provided for the researchers and students interested in more details of the basic theory. Chapter 2 can be skipped by those individuals not requiring more information on the basic theory of NMR. The next several chapters of the book are on applications of MRI to food systems.

Sensor technologies have experienced dramatic growth in recent years, making a significant impact on national security, health care, environmental improvement, energy management, food safety, construction monitoring, manufacturing and process control, and more. However, education on sensor technologies has not kept pace with this rapid development ... until now. Resistive, Capacitive, Inductive, and Magnetic Sensor Technologies examines existing, new, and novel sensor technologies and—through real-world examples, sample problems, and practical exercises—illustrates how the related science and engineering principles can be applied across multiple disciplines, offering greater insight into various sensors’ operating mechanisms and practical functions. The book assists readers in understanding resistive, capacitive, inductive, and magnetic (RCIM) sensors, as well as sensors with similar design concepts, characteristics, and circuitry. Resistive, Capacitive, Inductive, and Magnetic Sensor Technologies is a complete and comprehensive overview of RCIM sensing technologies. It takes a unique approach in describing a broad range of sensing technologies and their diverse applications by first reviewing the necessary physics, and then explaining the sensors’ intrinsic mechanisms, distinctive designs, materials and manufacturing methods, associated noise types, signal conditioning circuitry, and practical applications. The text not only covers silicon and metallic sensors but also those made of modern and specialized materials such as ceramics, polymers, and organic substances. It provides cutting-edge information useful to students, researchers, scientists, and practicing professionals involved in the design and application of sensor-based products in fields such as biomedical engineering, mechatronics, robotics, aerospace, and beyond.
