Quantitative Susceptibility Mapping gives a systematic account of the fundamentals of physical concepts, technical algorithms, and biomedical applications associated with magnetic resonance imaging of tissue magnetism. Recent progresses in MRI phase analyses and in numerical optimization solvers of inverse problems and promising applications in studying iron and oxygen metabolisms and hemorrhage have attracted many people to investigate quantitative susceptibility mapping (QSM). The objective of this book is to provide a comprehensive and timely introduction for the newly formed and rapidly growing QSM community. Emphasis has been placed on clarity throughout the narrative. Detailed considerations are presented to clarify the subtleties of the physics of magnetism and magnetic resonance signals: - Thorough demonstrations of the forward problem from magnetic susceptibility to field. - Comprehensive descriptions of major approaches to solving the field to susceptibility inverse problem. - Specific examples of clinical and scientific applications. Engineers, physicists, and clinicians at all levels, from students to established investigators, will find Quantitative Susceptibility Mapping a useful aid in understanding the physical principles of magnetic resonance imaging of tissue magnetic properties.

Principles of Magnetic Resonance Imaging provides a contemporary introduction to the fundamental concepts of MRI, applies these concepts in biomedical applications, and relates these concepts to the latest MRI developments. A unified approach based on spin phase factor averaging is supplied to connect microscopic molecular processes with macroscopic MRI contrasts: relaxation, transport and magnetism. Graphic illustrations of Bloch Equation solutions and various biophysical processes are presented for visualizing abstract ideas. Simplified calculations and specific examples are given for precise appreciation of fundamental concepts. Insightful interpretations and clinical examples are furnished for exemplifying biomedical information in MRI. This book contains three parts: I. Section the body into voxels. Part I describes the Fourier encoding matrix for imaging, its realization in magnetic resonance (MR) using gradient fields, and k-space sampling.II. What's in a voxel? Part II examines the effects of biophysical processes on MRI voxel signal. Spin phase factor averaging over the observation time and voxel space is provided as a unified biophysical model for explaining major MRI contrasts: Proton-proton interaction in a short range defined by local cellular contents (relaxation) causes T2 signal decay and T1 energy loss.Proton motion (transport) including diffusion, perfusion, flow and biomechanical motion can be measured as a phase contrast or signal decay using a gradient field.Electron-proton interaction (magnetism: nonlocal effects of magnetic susceptibility and local effects of chemical shift) can be quantitatively analyzed from MRI signal phase.The connection of MRI contrast physics to tissue molecular contents is conceptualized in the following three terms: 1) cellularity for T2 weighted imaging and diffusion weighted imaging (the latter emphasizing cellular geometry), 2) vascularity for T1 weighted imaging with Gadolinium injection, MR perfusion, and MR angiography, and 3) biomolecularity for MR spectroscopy and magnetic susceptibility imaging.III. How to operate an MRI machine? Part III describes MRI safety issues, hardware, software including advanced imaging methods, MRI scanning, and routine MRI protocols.As examples of applying basic physics concepts, this MRI book further illustrates the latest technological innovations, including: B_(1+)and B_(1-) mapping; Chemical exchange saturation transfer (CEST); Electric property tomography (EPT); Magnetic particle imaging (MPI); MR elastography (MRE); Moving spin tagging including ASL, SPAMM and DENSE; Navigator motion compensation; Parallel or accelerated imaging including SENSE, GRAPPA, compressed sensing and other Bayesian approaches; Quantitative susceptibility mapping (QSM)

Introductory Medicine for Engineers provides a concise introduction of the basic concepts of clinical medicine and hospital culture to engineers. This book aims to bridge the gap between engineering discipline and medical practice, so that engineers may feel confident in working with medical professionals to advance healthcare technology. This book is largely developed from the Clinical Summer Immersion Program for Biomedical Engineering PhD Students at Cornell University, which the author has been directing for the past decade. Introductory descriptions of medicine and medical practice covered in this book include - General cultures and customs of a hospital - Medical terminology - Diagnosis based on medical imaging - Surgical devices and basic surgical treatment - Process of medicine - Basics of pharmaceuticals

This book analyzes the social, economic, and political impact of Han Chinese migration into the borderlands that became Inner Mongolia during the Qing period. Linking local history to global movements, Yi Wang traces Inner Mongolia's integration into what would become the nation-state of China and from there into a global capitalist economy.

Focusing on the urban changes that took place under the market economy after 1978 and beyond, the book addresses the demolition of courtyard houses in Beijing's old city, the relocation of low-income families from the old city, the government's role regarding housing in the city, and residential segregation in Beijing.

This thesis focuses on magnetic reconnection processes in the boundary layer of the interplanetary magnetic cloud. In addition, after analyzing the particle flux variations in Magnetic Cloud Boundary Layer, the thesis proposes a possible new criterion for the identification of magnetic reconnection in the solar wind.
