A method for simulation of pulsed pressure fields from arbitrarily shaped, apodized and excited ultrasound transducers is suggested. It relies on the Tupholme-Stepanishen method for calculating pulsed pressure fields, and can also handle the continuous wave and pulse-echo case. The field is calculated by dividing the surface into small rectangles and then Summing their response. A fast calculation is obtained by using the far-field approximation. Examples of the accuracy of the approach and actual calculation times are given.
提出了一种用于模拟任意形状、变迹和激励的超声换能器产生的脉冲压力场的方法。它依赖于Tupholme-Stepanishen方法来计算脉冲压力场，并且还能处理连续波和脉冲回波情况。通过将表面划分为小矩形，然后对它们的响应进行求和来计算场。利用远场近似可实现快速计算。给出了该方法的精度示例和实际计算时间。
