Abstract:
The progression of measurement techniques and standardization for basic ultrasonic parameters in China in the last thirty years is expressed by combining author’s research.The further development is looked up.These progresses include the improvement of the method of radiation force balance(RFB),such as a number of new derived formulas of radiation force and their application,which were tested and approved by colleagues of IEC,the expended application area of RFB to various focused beams from unfocused beam and the range up to 500W from 30W,and the developments of measuring hydrophones and of their calibration methods based on reciprocity principle,and the innovation on measurement techniques of acoustic power and field characteristics of high intensity focused ultrasound(HIFU) as well as working out the first national standard of HIFU measurement in the world,promoting the standardization works on HIFU in IEC etc.
