This well-established text describes the principles, applications and design of the medical instrumentation most commonly used in hospitals. Because equipment changes with time, the authors stress fundamental principles of operation and general types of equipment. They avoid detailed descriptions and photographs of specific models. Design principles are emphasized so that a scientist with only some background in electronics can gain enough information to design instruments that may not be commercially available. Since biomedical engineering is an interdisciplinary field, the authors have provided varied healthcare industry applications for each type of instrument.
