Recent advancements in nano/micro materials and related characterization approaches allow the design of a new type of ultrasound contrast agents (UCAs) with enhanced multifunctional behaviour. This is chance is also supported by the recent achievements in modelling and signal processing. This book provides the state of art of the research activity of two successful European projects, TAMIRUT and SIGHT, addressing an integrated system, encompassing the contrast agent, the hardware equipment and the processing strategies, as a key tool for a combined diagnostic and therapeutic approaches (theranostics) in medical ultrasound. The work provides a highlight of the state of art in the research of novel ultrasound contrast agents (UCAs). Main progresses on the multifunctional aspects of next-generation UCAs concern targeting and drug release properties, perfusion and biointerface behaviour, ultrasound scattering performance, signal processing, electronic equipment.

This book will familiarize the reader with recent advances in echo imaging technology with special emphasis on echo enhancing agents. Several important strides have been made in this field during the past few years, especially in the contrast enhancement of conventional and color Doppler images. The book begins with chapters on the history of contrast echocardiography, the principles of contrast echo and descriptions of new contrast agents capable of transpulmonary passage following intravenous injection. Safety issues in contrast echocardiography are also discussed. The second section of the book deals with clinical uses of echo contrast agents. Their usefulness in the identification of cardiac structures and assessment of pathological lesions using both transthoracic and transesophageal echocardiography are fully discussed. Technical and practical considerations in the use of various contrast agents are also described. The use of contrast echo in the identification of cardiac sources of embolism as well as possible mechanisms and clinical significance of spontaneous contrast echoes are also covered. Six chapters fully discuss the basics of contrast enhancement of conventional and color Doppler images and its clinical utility in the noninvasive assessment of pulmonary artery pressure, regurgitant and stenotic lesions and in the delineation of coronary arteries. Another chapter describes the non-cardiac applications of the echo contrast enhancement technique. The final section of the book investigates the role of echo contrast enhancement in quantitative cardiovascular analysis.

Journalists, always very direct and in search of sensation, essentially asked me two questions on the occasion of this workshop: What were the goals of the meeting? With the improvement of diagnosis through the development of image techniques, didn't the contrast media already have their future behind them? Many answers were provided during the course of the workshop, and in order to best answer the journalists I proposed the following synopsis. 1. Since the 1979 Colorado Springs workshop organized by E. Lasser, progress has been so rapid and the newly available works so numerous that another meeting on an international level for the purpose of pre senting and discussing these advances appeared indispensable. Why not then in Europe and why not in Lyon? To expand on this progress, by 1981 the new contrast media with less-hyperosmolar molecules, still in the trial stage in 1979, were al most all available commercially for angiography, albeit at prohibitive prices. The advantages of these various media are becoming better known; moreover, in the wake of Lasser's work, our understanding of the pathophysiology of their noxious effects is also advancing rapidly owing to the use of models (for the target organs: heart, vessel wall, nervous system, kidney; and for the more general reactions: blood cells, coagulation, complement system, circulating enzymatic systems). In addition, further new molecules are currently being studied in re search laboratories. 2.

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

The value of ultrasound contrast agents (USCA) in everyday clinical practice depends on the pharmacokinetics, the signal processing, and the contrast-specific imaging modalities. Second-generation USCA, are blood pool agents that do not leak into the organ tissue to be examined but remain in the intravascular compartment increasing the Doppler signal amplitude during their dynamic vascular phase. Taking advantage of the stability of their microbubbles, they can withstand the acoustic pressure of insonation much better than first-generation contrast media, which results in an increased half-life of the agent and, consequently, in a prolonged diagnostic window. Concomitant with the improvement of contrast agents, different contrast-specific imaging modalities have been developed which, used in combination with USCA and a low mechanical index, allow continuous real-time grey-scale imaging. These recent technical improvements have opened new possibilities in the use of USCA in a variety of indications. Written by internationally renowned experts, the contributions gathered in this book give an overview of current and possible future new applications of USCA in routine and clinical practice.
