Part of the popular How, Why and When series of introductory textbooks, Ultrasound Physics and Technology is ideally tailored for students and healthcare practitioners needing a comprehensive understanding of the basic principles behind how sound waves and echoes create ultrasound images. Easy to read, concise and highly accessible, this book is perfect for readers who do not have a physics or technology background. It covers how ultrasound produces diagnostic images, why it is used in different clinical scenarios, and when its use as a diagnostic tool is appropriate. The book has been fully updated to incorporate the latest technology and developments, and will be an invaluable guide for all sonography practitioners and students who wish to practise ultrasound safely and effectively. Covers all the fundamental physics and technological knowledge needed to practise ultrasound effectively, including safety aspects, quality assurance, and the latest techniques and developmentsClear and concise explanations for those new to ultrasound physics and technology - no prior knowledge or experience necessaryStep-by-step introduction to the topics, covered in a logical order - each chapter builds on content covered in previous chaptersLearning outcomes and chapter summaries support learningEasy to read and follow - written in non-technical language for readers from a variety of training backgrounds. Takes a non-mathematical approach to explain the principles of ultrasound physicsUses a variety of examples from clinical practice used to bring learning to lifeIdeal for students but also valuable as a quick reference guide for all medical practitioners of ultrasound, from sonographers to doctors and midwivesNew to this edition Covers advancements in transducer technologyLooks at integration of ultrasound with other imaging modalities such as CT and MRI for more accurate diagnostic evaluations.
