提出了一种模拟任意形状、apoapozed和激发态超声换能器脉冲压力场的方法。它依靠Tupholme-Stepanishen方法计算脉冲压力场，也可以处理连续波和脉冲回波情况。磁场的计算方法是将表面分成小矩形，然后将它们的响应求和。采用远场近似法进行了快速计算。给出了该方法的精度和实际计算次数的实例。
A method for the 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 farfield approximation. Examples of the accuracy of the approach and actual calculation times are given.
