Estimating Acoustic Peak Pressure Generated by Ultrasound Transducers from Harmonic Distortion Level Measurement
Ultrasound in Medicine & Biology , Volume 34 - Issue 9 p. 1528- 1532
Pressure amplitude measurement is important for general research on ultrasound. Because it requires high accuracy, it is usually done using a hydrophone calibrated by an accredited laboratory. In this paper, a method is proposed for estimating the pressure amplitude in the ultrasound field using an uncalibrated single-element transducer and Khokhlov-Zabolotskaya-Kuznetsov simulations of the ultrasound field. The accuracy of the method is shown to be better than 20% for slightly focused and nonfocused transducers. Extending the method to a pulse-echo setup enables pressure measurement of a transducer without the need for an extra transducer or hydrophone. (E-mail: firstname.lastname@example.org).
