本文介绍了一种新研制的超声环形阵列探头。该探头具有一个陶瓷超声换能器，其具有凸表面以发射具有低方向性的超声波，以及围绕换能器的八个聚合物水听器以接收具有高灵敏度的反射波。首先，我们测量了一种陶瓷换能器的声压分布，证实了该换能器可以发射低指向性的超声波。其次，我们进行了实验，以重建一个金属球的三维图像使用该探头。实验结果表明，该探头能够提供更高分辨率的图像。
This paper describes a newly developed ultrasound ring array probe. The probe has one ceramic ultrasound transducer with a convex surface to transmit ultrasound wave with low directivity and eight polymer hydro-phones surrounding the transducer to receive reflected wave with high sensitivity. Firstly, we measured acoustic pressure distribution of a ceramic transducer and confirmed that the transducer can transmit ultrasound with low directivity. Secondly, we performed experiments to reconstruct a 3D image of a metal ball using this probe. The experimental results indicated that this probe enable to present the image with higher resolution.
