This updated fourth edition provides current information on devices and is divided into diagnostic and treatment sections.Devices are described with the theory of operation and relevant anatomical and physiological considerations.Aspects of BMET work including test equipment, standards, and information technology are also discussed.The text covers a wide variety of diagnostic and treatment devices currently used in hospitals that students will likely encounter in their career.Principles of operation and examples of use are provided.This book is unique in that it is written by an experienced biomed tech with 30 years’ experience in hospitals rather than by engineers with little frontline experience.It is also unique in that it provides ancillary materials on the web and is the only guide divided into diagnostic and treatment device sections.This new edition also includes two new chapters on computers, information technology, and networking as well as health technology management. From the previous edition:"The book presents a comfortable balance between clinical applications, basic technical information, and various pictures of medical technologies one will encounter in the field.Additionally, related anatomy and physiology principles and essential technical terms are a nice complement to the technologies presented.The everyday duties and responsibilities of a biomed are captured by the various ‘true-to-life’ scenarios introduced throughout the book."—Joey Jones, Madisonville Community College, Kentucky, USAThis book is intended for students in biomedical engineering technology and healthcare technology management (BMET/HTM) programs as well as biomedical engineering students.Field service representatives, medical device designers, and medical device sales representatives will also find it useful.
