U L T R A S O U N D : ITS C H E M I C A L , P H Y S I C A L A N D B I O L O G I C A L E F F E C T S Edited by K. S. Suslick. VCH Publishers Inc., New York, 1988, 336 pp., $65.00. This book on the effects of ultrasound is a new production of a format which has proven useful and enduring in the past. The eight chapters are: "Acoustic Cavitation and Bubble Dynamics" by Atchley and Crum, "Other Nonlinear Acoustic Phenomena" by Rooney, "Industrial Applications of Ultrasound" by Shoh, "Homogeneous Sonochemistry" by Suslick, "Heterogeneous Sonochemistry" by Boudjouk, "Sonoluminescence" by Verrall and Sehgal, "Biological Effects of Acoustic Cavitation" by Frizzell, and "Biological Effects of Ultrasound in Clinical Applications" by ter Haar. The book is nicely manufactured, with readable printing. However, the figures are in a variety of styles and appear to be photocopies of previously published material. The most recent citations listed in the chapters are from 1986. As indicated by the title, effects are strongly emphasized, so that many applications (e.g., medical imaging) and other topics in ultrasonics (e.g., absorption, and nonlinear acoustics) are not discussed. The contents of the book do not completely live up to the ambitious title. The chapters are uneven not only in style, which is common for such a collection, but also in substance. Some are brief overviews, while others present a thorough analysis of a topic. Half the chapters, and at least two thirds of the pages and literature citations deal with the chemistry and physics of cavitation, primarily as it is used in industry. Thus, some physical effects, such as heating and acoustooptical phenomena, are virtually left out. The treatment of the bioeffects area is also relatively meager

with, for example, only about three pages devoted to the ubiquitous thermal mechanism of megahertz frequency ultrasound. The medical applications of ultrasonic effects, such as in physical therapy, dentistry, hyperthermia treatment, and surgical intervention, are not well presented, which mostly leaves discussions of nonmammalian effects and the possibility of cavitation bioeffects in diagnostic ultrasound. Unfortunately, in keeping with the book's emphasis on effects, the diagnostic utility of ultrasound is not presented, which tends to give an incomplete picture of risks and benefits. One virtue of a volume of this type is that authoritative reviews, which might only be available separately from scattered sources, are collected into a comprehensive unit. This book is particularly strong on the physics and chemistry of cavitation with an industrial orientation. The chapter by Verrall and Sehgal on sonoluminescence is excellent and could become a standard general reference on the topic. The chapters by Rooney, which reviews work on acoustic streaming and radiation forces, and by Suslick, which reviews the subject of sonochemistry, are also particularly worthwhile reading. This volume seems to be the first book of its kind for several years, and thus may be a useful addition to many libraries. It would certainly be a valuable addition to any library serving researchers in physical chemistry or ultrasonics.

NONINVASIVE CARDIAC IMAGING: RECENT DEVELOPMENTS Edited by Richard S. Meltzer, Svi Vered, and Henry N. Neufeld. Futura Publishing Co., Mount Kisco, NY, 1988, 376 pp., $75.00. This book is a 376 page edited collection of articles covering the spectrum of available techniques in noninvasive cardiac imaging. There are sixteen individual chapters, grouped into four larger sections. The divisions receiving the greatest emphasis are echocardiography and nuclear cardiology, which are each composed of multiple chapters by individual authors. In separate segments, there are contributions on digital subtraction angiography, cardiac CT and magnetic resonance imaging, as well as external pulse recordings and systolic time intervals. Since the editors have substantial interests in echocardiography, those sections receive the greatest number of contributions and could be considered the primary focus of the book. The authors con-

tributing individual chapters are major figures in the field and write authoritatively on general aspects of each subject. The echocardiography section has chapters generally discussing quantitation, coronary artery disease, exercise, transesophageal and contrast echocardiography, as well as multiple contributions on Doppler. The individual chapters are well organized and concise and can be read individually. They provide an up-to-date summary of the general opinions in the field on the area of clinical utility. Print quality is over all excellent and there are four pages of color Doppler imaging, which at least serves as an introduction to that technique. Only the graphic illustrations in the chapters on positron emission tomography and digital 691
