Recent advances in power electronics greatly benefit the multidisciplinary field of modern ultrasonics. More powerful compact, and versatile electronic chips and software enable new computer-based devices for real-time data capture, storage, analysis, and display and advance the science and technology employed in commercial systems and applications of ultrasound. Reviewing the scientific basis behind these improvements, this book discusses them in detail, with new and additional figures and references, offering a completely revised and expanded examination of the state of modern ultrasonics.
