This book provides current, comprehensive, and clear explanations of the physics behind medical and biomedical applications of shock waves. Extracorporeal shock wave lithotripsy is one of the greatest medical advances of our time, and its techniques and clinical devices are continuously evolving. Further research continues to improve the understanding of calculi fragmentation and tissue-damaging mechanisms. Shock waves are also used in orthopedics and traumatology. Possible applications in oncology, cardiology, dentistry, gene therapy, cell transfection, transformation of fungi and bacteria, as well as the inactivation of microorganisms are promising approaches for clinical treatment, industrial applications and research. Medical and Biomedical Applications of Shock Waves is useful as a guide for students, technicians and researchers working in universities and laboratories. Chemists, biologists, physicians and veterinarians, involved in research or clinical practice will find useful advice, but also engineers and physicists may benefit from the overview of current research endeavors and future directions. Furthermore, it may also serve to direct manufacturers towards the design of more efficient and safer clinical, industrial and laboratory equipment.
Over the past twenty years, stress echocardiography has developed into a well-established technique that is versatile, patient friendly, and relatively inexpensive. This new, extensively revised and enlarged edition of Stress Echocardiography documents all of the very significant advances made since the fourth edition. The early chapters place the technique within a historical context and describe its pathophysiological basis. Thereafter, all aspects of stress echocardiography are discussed, clearly and in detail, by the distinguished pioneer, Eugenio Picano, and other contributors carefully selected for their expertise. Both mainstream and emerging applications are explained, and systematic comparisons with competing and complementary cardiac imaging techniques are provided. The text is supported by a large number of high-quality illustrations. This book is invaluable not only to cardiologists but also to non-experts, such as technicians and students.

In the later stages of gestation, fetal functions undergo increasing change and development, preparing the fetus for the transition to its postnatal environment. Rapid maturation is witnessed in breathing, swallowing, sensory functions, sleep, and many other processes, with corresponding behavioral changes. By 35 to 40 weeks of gestation, fetuses are capable of living ex utero without support, but it is increasingly appreciated that even infants born at between 35 and 36 weeks can suffer long-term consequences. This book, which complements the author's previous volume on development of normal fetal movements during the first 25 weeks of gestation, discusses in detail the full range of behavioral phenomena observed during the final 15 weeks of gestation, with careful analysis of their mutual relationships. A key feature is the outstanding photographic material, difficult to obtain at this late stage, and the instructive graphs that are also included. The information provided will alert clinicians to deviations from the norm and to physiologic phenomena that can turn pathologic in infants born prematurely.
The 29th International Symposium on Acoustical Imaging was held in Shonan Village, Kanagawa, Japan, April 15-18, 2007. This interdisciplinary Symposium has been taking place every two years since 1968 and forms a unique forum for advanced research, covering new technologies, developments, methods and theories in all areas of acoustics. In the course of the years the volumes in the Acoustical Imaging Series have developed and become well-known and appreciated reference works. Offering both a broad perspective on the state-of-the-art in the field as well as an in-depth look at its leading edge research, this Volume 29 in the Series contains again an excellent collection of seventy papers presented in nine major categories: (1) Strain Imaging, (2) Biological and Medical Applications, (3) Acoustic Microscopy, (4) Non-Destructive Evaluation and Industrial Applications, (5) Components and Systems, (6) Geophysics and Underwater Imaging, (7) Physics and Mathematics, (8) Medical Image Analysis, (9) FDTD method and Other Numerical Simulations.
Quantitative ultrasound (QUS) of bone is a relatively recent research field. The research community is steadily growing, with interdisciplinary branches in acoustics, medical imaging, biomechanics, biomedical engineering, applied mathematics, bone biology and clinical sciences, resulting in significant achievements in new ultrasound technologies to measure bone, as well as models to elucidate the interaction and the propagation of ultrasonic wave in complex bone structures. Hundreds of articles published in specialists journals are accessible from the Web and from electronic libraries. However, no compilation and synthesis of the most recent and significant research exist. The only book on QUS of bone has been published in 1999 at a time when the propagation mechanisms of ultrasound in bone were still largely unknown and the technology was immature. The research community has now reached a critical size, special sessions are organized in major international meetings (e.g., at the World Congress of Biomechanics, the annual meetings of the Acoustical Society of America, International Bone Densitometry Workshop, etc...). Consequently, the time has come for a completely up to date, comprehensive review of the topic. The book will offer the most recent experimental results and theoretical concepts developed so far and is intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The central part of the book covers the physics of ultrasound propagation in bone. Our goal is to give the reader an extensive view of the mathematical and numerical models as an aid to understand the QUS potential and the types of variables that can be determined by QUS in order to characterize bone strength. The propagation of sound in bone is still subject of intensive research. Different models have been proposed (for example, the Biot theory of poroelasticity and the theory of scattering have been used to describe wave propagation in cancellous bone, whereas propagation in cortical bone falls in the scope of guided waves theories). An extensive review of the models has not been published so far. We intend in this book to present in details the models that are used to solve the direct problem and strategies that are currently developed to address the inverse problem. This will include analytical theories and numerical approaches that have grown exponentially in recent years. Most recent experimental findings and technological developments will also be comprehensively reviewed.

To continue the support for the growing trend of chemistry involvement in nuclear medicine, the Division of Nuclear Chemistry and Technology (DNCT) of the American Chemical Society (ACS) planned for a symposium to cover this aspect. This was expressed in arequest to me, as a member of the Program Committee, to organize a symposium on topics related to nuclear and radiochemistry applications to nuclear medicine. Realizing the growing interest in imaging, specially with positron emitting radioisotopes, I invited several colleagues to study with me the idea of imaging centers and the involvement of chemists in their structure and function. The formulated Organizing Committee supported this idea which evolved in proposing an extended international symposium to be held in conjunction with the 206th ACS National meeting in Chicago, Illinois, U. S. A. on August 22-27, 1993. The following are the members of the Organizing Committee: Jorge R. Barrio, Ph. D. Thomas E. Boothe, Ph. D. J. Robert Dahl, Ph. D. Robert F. Dannals, Ph. D. Bruce R. Erdal, Ph. D. Mark M. Goodman, Ph. D. George W. Kabalka, Ph. D. James F. Lamb, Ph. D. Ronald G. Manning, Ph. D. Henry C. Padgett, Ph. D. Roy S. Tilbury, Ph. D. Steven W. Yates, Ph. D. and Ali M. Emran, Ph. D.

This book describes the role of basic and advanced imaging techniques in the diagnosis of different types of cardiomyopathy, including dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy and infiltrative/storage cardiomyopathies. While the main focus is on echocardiography, the applications of cardiac magnetic resonance imaging and computed tomography are also described. Throughout, a clinically oriented approach is employed: detailed attention is paid to differential diagnosis and numerous high-quality images depict the main features of the various types of cardiomyopathy. Consideration is also given to the genetics of cardiomyopathies, with analysis of genotype-phenotype relationships. Finally, the potential value of imaging in prognostic assessment and in guiding treatment is described.
There are two major reasons for having this symposium. First, Tohoku Univer sity is the place where ultrasound investigations in Japan originated. Starting from the research studies of Professors H. Nukiyama and Y. Kikuchi of To hoku University, Professor J. Saneyoshi of Tokyo Institute of Technology, and Dr. K. Kato of Osaka University - all graduates of Tohoku University - the results spread to all parts of Japan. More recently we have had acoustic macro scopic studies by researchers like Professor N. Chubachi. As regards tissue char acterization, which was the main theme of the symposium, the collaboration among research workers in Japan and the United States started 10 years ago between Professor F. Dunn of the University of Illinois and staff members of Tohoku University and the Tokyo Institute of Technology. So this conference commemorates the lOth anniversary of that joint research effort. The second reason for this conference is that the application of ultrasound has become wide spread and indispensable in the routine clinical activities of medicine. But there have not been many breakthroughs in terms of quantitative and qualitative measurement of the living body tissues. Also, there are many problems with regard to practical application. There are various points that have not been elucidated yet as to the physical and acoustical characteristics of ultrasound itself. The methodology has not in all cases been well established. Therefore, the scientific elucidation of these areas is essential.
Cardiovascular fluid mechanics is now used as a tool in determining diagnosis, treatment, and prognosis by physicians and surgeons working in the fields of cardiology and angiology. The text is based on a considerable amount of clinical and experimental data on blood flow in the heart and large vessels obtained using various methods such as ultrasound pulsed Doppler velocimetry (including Doppler color flow imaging), catheter-tip electromagnetic velocimetry, hot-film anemometry, and laser Doppler velocimetry. The book will introduce medical researchers and clinicians to this rapidly developing field and allow them to apply the knowledge and the methods of fluid mechanics to practical medicine.
A basic text and instruction manual of diagnostic ultrasound which is directed towards the student or health care provider- non-radiologist and non-sonographer- wishing to begin performing and understanding ultrasound. It covers basic concepts of diagnostic ultrasound. While the emphasis is on obstetric ultrasound, it also includes applications for gynecology, trauma, abnormal fluid collections, liver and biliary diseases, hydronephrosis and renal disease, and small parts (e.g. breast, thyroid, testicle, extremity, etc.). A primary goal is to teach the practitioner how to use ultrasound to help determine which patients should be referred to a center where a higher level of care can be provided. The book was initially conceived and created for practitioners in rural low resource areas but would be useful in a wide variety of settings.
Diagnostic and Therapeutic Ultrasound has recently taken an explosive growth for better safer, economic, mobile and high quality healthcare. This technology is very appealing for medical applications because it is non-ionizing, non-invasive and it is available in most of the medical and clinical facilities. Its low cost, when compared with other medical image modalities, makes it one of the preferred tools for medical monitoring, follow-up and diagnosis. Besides the traditional fields of Cardiology and Obstetrics, where it is extensively used for long time, it has became also very useful in the diagnosis of diseases of the prostate, liver and coronaries and carotids atherosclerosis. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts. The extraction of useful information from Ultrasound data for diagnosis is a challenge task that makes this medical image modality a very active field of research. The difficulties are being overcome and novel and advanced methods are being proposed for detection, characterization and segmentation of abnormalities in several organs. In fact, Ultrasound application range is vast, covering almost all organs of the human body, including the brain where Tran-cranial Doppler Ultrasound is very important to assess the brain vasculature. This book presents some of the recent advances in Ultrasound imaging technology covering several organs and techniques in a Biomedical Engineering (BME) perspective. The focus of the book is in the algorithms, methodologies and systems developed by multidisciplinary research teams of engineers and physicians for Computer-Aided Diagnosis (CAD) purposes. Cardiovascular and Cancer, the most common life-threatening diseases in western countries, are two of the most important topics focused in the book. However, other advanced issues are also presented such as Intravascular Ultrasound, 3D US and Ultrasound in Computer-Aided Surgery (CAS). Some chapters are direct contributions from medical research groups where Ultrasound has also received great attention in the last decade. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities.
This unique ultrasound atlas is dedicated entirely to pathology of the scrotal contents. The 357 illustrations constitute the major proportion of the book, each of them is accompanied by a labelled diagram and detailed description. The atlas covers the essential embryology and ultrasound anatomy, the principal clinical presentations encountered in practice by the clinician and radiologists, and the differential diagnosis of intrascrotal cysts and calcifications. For each chapter there is a short but precise text, supplemented by tables or decision-making algorithms followed by the relevant images.
This book describes in detail the physical and mathematical foundations of ultrasonic phased array measurements.The book uses linear systems theory to develop a comprehensive model of the signals and images that can be formed with phased arrays. Engineers working in the field of ultrasonic nondestructive evaluation (NDE) will find in this approach a wealth of information on how to design, optimize and interpret ultrasonic inspections with phased arrays. The fundamentals and models described in the book will also be of significant interest to other fields, including the medical ultrasound and seismology communities. A unique feature of this book is that it presents a unified theory of imaging with phased arrays that shows how common imaging methods such as the synthetic aperture focusing technique (SAFT), the total focusing method (TFM), and the physical optics far field inverse scattering (POFFIS) imaging method are all simplified versions of more fundamental and quantitative imaging approaches, called imaging measurement models. To enhance learning, this book first describes the fundamentals of phased array systems using 2-D models, so that the complex 3-D cases normally found in practice can be more easily understood.In addition to giving a detailed discussion of phased array systems, Fundamentals of Ultrasonic Phased Arrays also provides MATLAB(r) functions and scripts, allowing the reader to conduct simulations of ultrasonic phased array transducers and phased array systems with the latest modeling technology."
"Endourology" provides a summary of the different endourological modalitites, especially the more advanced and controversial techniques, such as the antegrade resection of urethral valves, the transperineal I 125 seed implanations, the spoonloop resectoscope, flexible endoscopy, teflon injection to correct vesicoureteral reflux, stone manipulation in calyceal diverticula, as well as the extraperitoneal pelvioscopy. These techniques are supported by descriptions of the standard endourological procedures.
Marking the 200th National Meeting of the American Chemical Society, The Division of Nuclear Chemistry and Technology hosted a group of about 90 scientists from 15 different countries to discuss the new trends in radiopharmaceutical synthesis, quality assurance and regulatory control. This event took place in Washington, D.C. on August 27-30, 1990. When I first suggested the idea for this symposium, a group of scientists who pioneered the proposed topics offered their help to organize and run such a big task with me. Their names are listed here in appreciation. Thomas E. Boothe Cyclotron Facility, Mt. Sinai Medical Center, Miami Beach, Florida, USA Robert F.

Their effort is sincerely acknowledged.
The opacification of the left ventricle by echo cardiographic contrast agents (echoventriculography) represents an alternative to cineventriculography, as determinations of left ventricular volume and ejection fraction are accurate and highly reproducible, when methods like color superposition and statist- ical imaging techniques are used in order to improve the outlining of the cavity and endocardial border. Detection of perfusion defects is possible [40]. The enhancement of myocardial contrast during the perfusion phase after injection into the left ventricle or the aorta further improves the endo- cardial border delineation. For practical purposes, the direct injection of echocardiographic contrast is inferior to the indirect opacification after per- ipheral venous injection which can be achieved with sonicated albumin, Albunex(R), SH U 508 A, HOE 155. These drugs are presently under clinical investigation. In up to 90% of the patients, left heart opacification is possible, yielding 30% intensity of the right ventricle. When these drugs are available, sophisticated computed methodologies have to be included in the echocardio- graphic machines in order to improve the determination of the left ventricular volume and ejection fraction [44]. In the future, cineventriculography will be rarely performed as echoventriculograms already show left ventricular contraction. This will possibly result in reduced side effects and costs.

The International Symposium of Acoustical Imaging has been widely recognized as the premier forum for presentations of advanced research results in both theoretical and experimental development. Held regularly since 1968, the symposium brings together th leading international researchers in the area of acoustical imaging. The 24 meeting is the third time Santa Barbara hosted this international conference and it is the first time the meeting was held on the campus of the University of California, Santa Barbara. As many regular participants noticed over the years, this symposium has grown significantly in size due to the quality of the presentations as well as the organization itself. A few years ago multiple and poster sessions were introduced in order to accommodate this growth. In addition, the length of the presentations was shortened so more papers could be included in the sessions. During recent meetings there were discussions regarding the possibility of returning to the wonderful years when the symposium was organized in one single session with sufficient time to allow for in-depth presentation as well as discussions of each paper. And the size of the meeting was small enough that people were able to engage in serious technical interactions and all attendees would fit into one photograph. In light of the constraints of the limited budget with respect to the escalating costs it was not considered feasible. |
