Abstract

Measurement plays a pivotal role in all aspects of medical ultrasound. Meaningful measurements require common measurement standards and must be underpinned by common methods of measurement. For ultrasonic field measurement, the former has been achieved in a number of national metrology institutes world wide by establishing measurement standards for important physical quantities, namely acoustic pressure and time-averaged ultrasonic power. Common methods of measurement are based on the development of international specification standards. These provide relevant definitions of parameters and protocols to enable standard measurements to be made and also to establish a common basis for comparing measured values. This paper provides a brief review of the progress made in the establishment and validation of measurement standards and in the development of specification standards published by the International Electrotechnical Commission.
