Introductory objectives by chapter describes the level of material to be presented. Problems by chapter with short questions to test understanding of the main principles and longer questions to test more in-depth knowledge. Extensive cross-referencing ensures that students can obtain detailed understanding of a particular subject. Detailed bibliographies provide references to introductory texts and research materials. This is a self-contained text suitable for taught courses in medical physics and biomedical engineering. It is based on the successful Bachelor's and Master's courses run at Sheffield University. It provides a solid foundation for physics and engineering students approaching medical physics and biomedical engineering for the first time. Practising medical physicists and biomedical engineers on continuing professional development courses as well as clinicians interested in the technological aspects of medicine will find much of interest in its breadth of coverage. The text is split into two parts, where the first part presents the underlying physics, electronics, anatomy and physiology, and the second addresses practical applications. The structured approach means that later chapters build and broaden the material introduced in the opening chapters. Students taking particular options, for example audiology, just may read the relevant chapters covering the introductory science (e.g. chapter three covers the physics of hearing) and then its practical application (in this chapter fifteen covers the practical applications of this in audiology). Some of the material in this book was originally published as Medical Physics and Physiological Measurement. The earlier book was written at a lower level as an introduction for technical staff and for graduates. The new book provides much broader coverage and is written at a higher level, appropriate for senior undergraduates and graduates on taught courses or undertaking research in medical physics and biomedical engineering. Some parts of the book require knowledge of mathematics as taught on physics or engineering first degrees. Where necessary references to the mathematical background are provided and detailed derivations are kept to a minimum. Comprehensive references to junior undergraduate texts in physics, electronics and life sciences are provided in the bibliographies at the end of each chapter. Coverage includes: Biomechanics, ionising and non-ionising radiation and the measurements; image formation techniques and processing and analysis; safety issues, biomedical devices; mathematical and statistical techniques; physiological signals and responses; respiratory and cardiovascular function and measurement.
