Visualization and measurement of the acoustic field of the piston transducer

Abstract

Purpose

This paper aims to characterize the acoustic field radiated by the piston transducer and measure a few parameters through the data visualization method.

Design/methodology/approach

Using the theoretical model of the ultrasonic transducer, the acoustic field data were acquired by scanning the ultrasound field of the piston transducer. And the visualized graphs of the ultrasonic data were displayed through 3D graphs including slice, iso‐surface and volume rendering, respectively. Furthermore, a few parameters of the transducer including beam width and spread angle were measured using the visualized data.

Findings

The visualized graphs of the acoustic field radiated by the piston transducer show that the data visualization method can expose obviously the space distribution of the ultrasound field and describe directly the cylindrical shape. And this method provides the basis of reliable measurement and assess for the ultrasonic transducer.

Research limitations/implications

This paper presents a kind of measured method of the acoustic parameters using the visualized data. The measurement range has limitation.

Practical implications

This method is possible used in Medical ultrasonic.

Originality/value

This paper presents the visualized description of the acoustic field of the piston transducer and a measurement of two acoustic parameters using the visualized data.
