研制了一种二维矩阵式Pb（ZrxTi 1-x）O3（PZT）陶瓷阵列，用于评价编码波前成像系统的原理。本文介绍了一种用于发射机和接收机的PZT 40 ×40单元阵列的制作工艺。由沃尔什函数调制的信号用于驱动发射机阵列元件。成功地获得了标准超声体模的三维图像。结果表明，该方法在医学诊断中是可行的。
A two-dimensional matrix Pb(ZrxTi1-x)O3 (PZT) ceramics array has been developed to evaluate the principle of an imaging system using a coded wavefront. In this paper, the fabrication process of a PZT 40 ×40 element array for transmitter and receiver is described. Signals modulated by the Walsh functions were used for driving the transmitter array elements. Three-dimensional images were successfully obtained for a standard ultrasonic phantom. It is shown that this method is applicable in medical diagnosis.
