Abstract: Abstract of thesis entitled Coil Array Optimization and Wireless Transceiver Design for MRI submitted by Wei Juan for the degree of Doctor of Philosophy at The University of Hong Kong in February 2007 In recent years, parallel imaging has revolutionized the field of fast MRI. Array coils with independent receivers and the use of the additional spatial encoding enable parallel imaging techniques much more efficiently. Recently, due to the cost reduction of RF receivers, the number of array channels has risen to 96. This thesis presents the author's investigations into the optimization of RF coil array for ultra high field MRI and the design of a wireless RF transceiver for MRI signal transmission. On the optimization of RF coil array, the author emphasizes the parallel imaging performance which is closely related to the uniqueness of each element sensitivity pattern. For such applications, the design process begins by choosing the number, shape and arrangement of the elements. Then the electromagnetic field modeling is applied to predict sensitivity patterns and the noise covariance matrix to calculate parameters such as G-factor and SNR dedicated to the evaluation of parallel imaging performance. However, the mutual coupling of coil array causes the shift of the resonant frequency of the elements and degrades their sensitivity. There are some decoupling techniques, such as the "geometric," "preamplifier" and "reactive" methods, but they make the coil array design much more complicated. An investigation into the intrinsic coupling characteristics of array elements is also presented in this thesis to provide a simple guidance to minimize the mutual coupling for array design. In recent years, there has been a trend to dramatically increase the number of receive channels of coil array to shorten imaging time without sacrificing much of their SNR. However, with many elements, the cable crosstalk and RF burn become the serious problem. Wireless transmission is a promising alternative to coaxial cables for the MRI coil array to avoid this problem. Although wireless links have been widely used in the field of telecommunications, some special critical issues for MRI are highly imposed in order to maintain the image quality. In this thesis, the wireless transmission system based on IEEE 802.11b standard is implemented. With this new technique the MR images of both phantom and human head are successfully obtained from XinaoMDT 0.3T MRI system (Langfang, China). In summary, the author optimizes the different RF coil arrays based on the simulations and bench tests to present guidelines for future coil array design. The implementation of digital wireless transmission and the MR images obtained have demonstrated the potential of wireless multi-channel transmission for MRI array.

This book covers all areas of smart antennas, electromagnetic interference, and microwave antennas for wireless communications. Smart antennas or adaptive antennas are multi-antenna components on one or both sides of a radio communication connection, combined with advanced signal processing algorithms. They've evolved into a critical technology for third-generation and beyond mobile communication systems to meet their lofty capacity and performance targets. It seems that a significant capacity gain is achievable, particularly if they are employed on both sides of the connection. There are several essential characteristics of these systems that need scientific and technical investigation. Included in the book are beamforming, massive MIMO, network MIMO, mmwave transmission, compressive sensing, MIMO radar, sensor networks, vehicle-to-vehicle communication, location, and machine learning.

This book describes the design of the first functioning single-sided tomograph, the related measurement methods, and a number of applications in medicine, materials science, and chemical engineering. It will be the first comprehensive account of this new device and its applications. Among the key advances of this method is that images can be obtained in much shorter times than originally anticipated, and that even vector maps of flow fields can be measured although the magnetic fields are highly inhomogeneous. Furthermore, the equipment is small, mobile and affordable to small and medium enterprises and can be located in doctors’ offices.

These volumes are an abstraction from the Encyclopedia of Nuclear Magnetic Resonance of articles concerned with magnetic resonance imaging and spectroscopy. The volumes cover imaging in all its forms, and spectroscopy in as far as it relates to in vivo studies, and clinical applications involving in vitro investigations of tissue. The various articles which comprise these two volumes are organised into topic-based sections. Some of the articles appear as they were originally presented in the Encyclopedia, where there is little new information, and some have been more or less substantially revised in the light of what has happened since the articles were first written. A number of new articles have been added where topics have either developed from fragmentary discussions in the early 1990s, or have been created ab initio since the publication of the Encyclopedia. These extensive volumes are unique in their coverage, with a balance between imaging physics, spectroscopy and clinical studies. In many ways, they reflect the scope covered by the major international in vivo NMR Societies, with a conscious effort to allow the reader to understand all the elements that make up modern clinical magnetic resonance. Equally, the topic is so huge, and still evolving so fast in detail, rather than concept, that they can act as no more than an introduction, though at quite a demanding level. The reader will appreciate the extent, nature and dynamics of human and animal magnetic resonance, and will have the route map to allow them to find any further information they may need.
