Abstract

Non-diffraction waves have great importance in medical imaging, especially the Bessel beams. In order to obtain a spatial ultrasound field of Bessel beams, this paper simulated with the use of a circular ultrasonic transducer and a set of concentric annular ultrasonic transducers and compared the simulation results. The results help to find out applied ways of zero-order Bessel ultrasonic field for production and using, which could simplify the structure of ultrasonic transducers and reduce the manufacturing difficulty and cost.
