Abstract

This paper aims at the measurement problem of High Intensity Focused Ultrasound (HIFU). In order to measure the sound parameters of HIFU, we study the near-field cross-spectrum method. That is to say, the complex sound pressure of two adjacent planes can be measured in the near field, besides, the sound power and the sound intensity can be obtained through the cross-spectrum relationship between two groups of sound pressure. For verifying the theory, we used a self-built underwater acoustic field measurement system to compare the far-field method with the near-field cross-spectrum method by measuring the sound power of the plane piston transducer, and the result shows that the near-field cross-spectrum method is reliable in the effective range of acoustic error.
