Diagnostic ultrasound is changing dramatically because of the development of a variety of high resolution real-time scanning instruments. Until recently the standard instrument was the articulated arm contact scanner. Real-time scanners were viewed as adjunct instruments for specific and limited pur poses. The roles are reversing with real-time instruments more frequently accepted as the primary diagnostic tool and the contact scanner becoming the ancillary instrument for use mainly for viewing a large field that cannot be scanned with real-time instruments. Two recent editorials stated that real-time instruments were used as the sole diagnostic instrument for between 80% [Cooperberg (2)] and 98% [Bartrum and Crow (1)] of their abdominal examinations. This book introduces the reader to the field of real-time scanning in the abdomen. It presupposes an understanding of basic physical concepts of ultrasound, the appearance of both normal and pathologic conditions as produced by static articulated arm contact scanning, and a familiarity with the techniques of contact scanning. It is designed to acquaint the reader with the spectrum of real-time instrumentation, provide a basic understanding of the physics of ultrasound as related to these instruments, emphasize the special skills required in the use of this equipment, and describe applications of real-time scanning for various parts of the abdomen. While numerous illustrations of both normal and pathologic anatomy are shown, the book is an all-inclusive study of abdominal pathology as demonstrated by real-time imaging.

Since the beginnings of diagnostic ultrasound in the 1950s, each decade has seen significant advances in this technology. Commer cialization of ultrasound occurred during the 1960s with the introduction of many of the clinical uses that are in existence today. The 1970s showed the most dramatic changes with the commercial introduction of gray-scale and real-time ultrasound. In the 1980s many new advances were introduced, including color Doppler, as well as a wide variety of endoluminal approaches, including endorectal, endovaginal and transesophageal. The decade of the 1990s promises even more significant advances with further transducer miniaturization, three-dimensional ultra sound, and the introduction of a variety of ultrasound contrast agents. With such rapid changes occurring, it becomes important to disseminate knowledge in as rapid a fashion as possible, thus it was quite appropriate that a meeting such as this be held to provide an in-depth review of the many new areas of ultrasound imaging that show promise for the future. Emphasis was on the new uses of ultrasound in gastrointestinal diseases. Many of these advances will, of course, also have applications in many other areas of the body. It is hoped that those in attendance will acquire a much broader understanding of where ultrasound is now and where it is headed in the not too distant future.

by Dr. Jan. J. Smulewicz Ultrasound imaging has reached a stage of sophistication where by diagnostic information can be gained without discomfort to the patient and with complete absence of morbidity and mortality. The procedure is quick, safe, noninvasive and in many instances can supersede and obviate more time-consuming procedures requiring catheterization, injection of a contrast material, and radiographic imaging. In obstetrical problems the danger of ionizing radiation to the fetus is eliminated. In debilitated and very ill patients this simple and painless method becomes the procedure of choice. Unique features of ultrasound equipment allow for pinpoint local ization oflesions and direct visual guidance of percutaneous puncture techniques for aspiration and biopsy. The accuracy of ultrasound guided punctures and the absence of side effects make this modality far superior to percutaneous invasive techniques performed with other imaging systems. Renal cyst puncture and amniocentesis are but two of the procedures in which ultrasonic guidance is the method of choice. v Dr. Hassani has throughly explained and carefully explored the wide variety of exam inations available with ultrasound. The large volume of material and the clear interpre- tion makes this book of great interest to all of the medical profession. In addition to the existing methods available for diagnostic in terpretations, this method of noninvasive diagnosis should find its way into every hospital or center where good medical care is provided.

This open access book deals with imaging of the abdomen and pelvis, an area that has seen considerable advances over the past several years, driven by clinical as well as technological developments. The respective chapters, written by internationally respected experts in their fields, focus on imaging diagnosis and interventional therapies in abdominal and pelvic disease; they cover all relevant imaging modalities, including magnetic resonance imaging, computed tomography, and positron emission tomography. As such, the book offers a comprehensive review of the state of the art in imaging of the abdomen and pelvis. It will be of interest to general radiologists, radiology residents, interventional radiologists, and clinicians from other specialties who want to update their knowledge in this area.

This book explains the exciting field of sonomyography (SMG), which makes it possible to use continuous signals detected by ultrasound images in real time to evaluate muscle functions. After an introduction, the book discusses the methods to extract and analyse different SMG signals, including muscle thickness, penetration angle, fascicle length, contraction activity, and muscle cross-sectional areas, etc. It then describes the mono-modal applications of sonomyography: posture recognition, prosthesis control, muscle training, muscle strength (fall risk assessment), fatigue assessment, and the assessment of dysfunctional muscles. The book also shows how to combine sonomyography with additional muscle assessment methods, in particular EMG, MMG, and motion sensors. Lastly, it provides an overview of the potential applications in sport science, rehabilitation, fitness, and elderly health.

The 11th International Conference on Medical Imaging and Computer Assisted Intervention, MICCAI 2008, was held at the Helen and Martin Kimmel Center of New York University, New York City, USA on September 6–10, 2008. MICCAI is the premier international conference in this domain, with - depth papers on the multidisciplinary ?elds of biomedical image computing and analysis, computer assisted intervention and medical robotics. The conference brings together biological scientists, clinicians, computer scientists, engineers, mathematicians, physicists and other interested researchers and o?ers them a forum to exchange ideas in these exciting and rapidly growing ?elds. The conference is both very selective and very attractive: this year we - ceived a record number of 700 submissions from 34 countries and 6 continents, fromwhich258papers were selectedfor publication,whichcorrespondsto a s- cess rate of approximately 36%. Some interesting facts about the distribution of submitted and accepted papers are shown graphically at the end of this preface. The paper selection process this year was based on the following procedure, which included the introduction of several novelties over previous years. 1. A ProgramCommittee (PC) of 49 members was recruited by the Program Chairs,to getthenecessarybody ofexpertiseandgeographicalcoverage.All PC members agreed in advance to participate in the ?nal paper selection process. 2. Key words grouped in 7 categories were used to describe the content of the submissions and the expertise of the reviewers.
