Ever since the earliest developments of medical ultrasound there has been an interest in the measurement and characterisation of the ultrasonic fields generated in these applications, either for assessment of performance of equipment or for safety. Until recently, procedures for acoustic ou

Fundamentals of Ultrasonic Propagation,of the characteristic parameters and much of the basic terminology will be introduced here and taken further during later chapters. However, these later chapters will deal with the practical aspects of measurement and characterisation, often assuming that the basic physical principles of measurement have been established.
