Abstract

A hydrophone scanning method is gold standard for the ultrasound filed measurement. However, the hydrophone scanning is time consuming especially for the three-dimensional measurement. On the other hand, two-dimensional data can be acquired simultaneously by an optical measurement method using a camera. In this study, the optical phase contrast method was used to measure a three-dimensional pressure filed generated by a focused transducer.
