Ultrasonics. Power measurement. High intensity therapeutic ultrasound (HITU) transducers and systems Ingestion-build-228203 Who is BS 1728-21 –1 Scope This International Standard establishes general principles relevant to HITU fields for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; specifies a calorimetric method of determining the total emitted acoustic power of ultrasonic transducers based on the measurement of thermal expansion of a fluid filled target; specifies requirements related to the statement of electrical power
