Essentials Of Ultrasound Imaging

Essentials of Ultrasound Imaging offers a fast track introduction to the science, physics and technology of ultrasound imaging systems. Uniquely, principles are revealed by examples from software simulation programs, thus allowing the reader to engage with the concepts having minimal mathematical background. The material is organized around a functional block diagram which is, in turn, related to physical processes and implementations of the functional concepts on commercial and research imaging systems. Examples from a Verasonics Vantage Research Ultrasound System provide unparalleled insight into each step of ultrasound image creation including signal processing, transducer operation, different types of beamforming, and image formation. The last chapter examines the potential and capabilities of ultrasound imaging and measurement for future applications. With a thorough grounding of the physics and methods of ultrasound imaging, this book is suitable for students learning about ultrasound and researchers involved, or starting out in, ultrasound research development who might not have the background to understand the latest developments. Gives an understanding of wave propagation, piezoelectric transducers, beam focusing, Doppler imaging of fluid flow, types of ultrasound systems, and real-time image formation and resolution Explains basic mathematical and scientific concepts underlying ultrasound imaging and physics Follows the passage of pulse-echo waveforms through the changes made by wave propagation, array beam formation, absorption, and system processing to image formation Describes the concepts written in MATLAB® that are illustrated by numerous examples from unique simulations of physics, processing, and imaging and from experiments and signals within an ultrasound research system Presents an accompanying simulator software package, in executable form, designed to demonstrate concepts with minimal mathematical background, together with a curriculum of hands-on experiments using an ultrasound research system, both available from Verasonics

One of the first applications of ultrasound was in submarine sonar equip ment. Since then ultrasound has found increasing applications, particularly in industry, but increasingly in biomedicine. For many years ultrasound has been used in physical therapy, although only in the past decade or two has it evolved from laboratory curiosity to a well-established diagnostic imaging modality. Ultrasound is now a widely accepted, indeed pervasive, diagnos tic and therapeutic tool in the medical field, and its applications are increasing rapidly. Our intent in developing this book is to provide a coherent tutorial intro duction to the field of medical ultrasound at a level suitable for those en tering the area from either medical or scientific backgrounds. The topics discussed should be of interest to nearly all medical and health care per sonnel needing to understand or operate ultrasonic devices, including clini cians, medical technicians, physiotherapists, medical physicists, and other biomedical scientists interested in the field. The book opens with a description of the basic principles of propagating acoustic waves, explains how they interact with a wide range of biological systems, and outlines the effects they produce. To provide practical infor mation to operators of ultrasound equipment, we have included thorough coverage of the details of ultrasonic instrumentation and measurement techniques, and set forth the framework for an effective quality assurance program.

Diagnostic Ultrasound Imaging provides a unified description of the physical principles of ultrasound imaging, signal processing, systems and measurements. This comprehensive reference is a core resource for both graduate students and engineers in medical ultrasound research and design. With continuing rapid technological development of ultrasound in medical diagnosis, it is a critical subject for biomedical engineers, clinical and healthcare engineers and practitioners, medical physicists, and related professionals in the fields of signal and image processing. The book contains 17 new and updated chapters covering the fundamentals and latest advances in the area, and includes four appendices, 450 figures (60 available in color on the companion website), and almost 1,500 references. In addition to the continual influx of readers entering the field of ultrasound worldwide who need the broad grounding in the core technologies of ultrasound, this book provides those already working in these areas with clear and comprehensive expositions of these key new topics as well as introductions to state-of-the-art innovations in this field. Enables practicing engineers, students and clinical professionals to understand the essential physics and signal processing techniques behind modern imaging systems as well as introducing the latest developments that will shape medical ultrasound in the future Suitable for both newcomers and experienced readers, the practical, progressively organized applied approach is supported by hands-on MATLAB® code and worked examples that enable readers to understand the principles underlying diagnostic and therapeutic ultrasound Covers the new important developments in the use of medical ultrasound: elastography and high-intensity therapeutic ultrasound. Many new developments are comprehensively reviewed and explained, including aberration correction, acoustic measurements, acoustic radiation force imaging, alternate imaging architectures, bioeffects: diagnostic to therapeutic, Fourier transform imaging, multimode imaging, plane wave compounding, research platforms, synthetic aperture, vector Doppler, transient shear wave elastography, ultrafast imaging and Doppler, functional ultrasound and viscoelastic models

Each title in this series features highlighted facts in an easy-to-use, bulleted format that should make study quick, efficient and enjoyable. Interesting and entertaining illustrations and boxed material help the reader to master and remember important concepts.

The present volume on basic physics of ultrasonographic imaging procedures provides clear and concise information on the physics behind ultrasound examinations in diagnostic imaging. It attempts to present the subject from a simple approach that should make it possible for the target groups to comprehend the important concepts which form the physical basis of ultrasonic imaging. The main target group of this manual is radiological technologists and radiographers working with diagnostic ultrasound in developing countries. Clinicians and nurse practitioners may also find the simple presentation appealing. A conscious effort has been made to avoid detailed mathematical treatment of the subject. The emphasis is on simplicity.

This report defines the essential training and skills necessary for the effective employment of diagnostic ultrasound in different health care settings. It reviews the present situation in ultrasonography and the trends in the utilization of diagnostic ultrasound in clinical practice. The report also examines worldwide practice with respect to ultrasonography training for physicians, sonographers, and other categories of medical professionals, such as midwives, nurses, and assistant physicians. It presents outlines of recommended training curricula for physicians in general, advanced, and specialized ultrasonography and discusses various other factors that must be taken into account in organizing the training process. The report describes the recommended training for allied health professionals specializing in ultrasonography and presents the basic science and instrumentation aspects of the curricula. It then discusses the level of competence that should be reached by those trained in the use of diagnostic ultrasound, as well as the recommended standards for training programs, including the requirements for instructors and training centers. Recommendations for the implementation of training programs are included. An appendix outlines the applications of diagnostic ultrasound. (Contains 36 references.) (MDM).
