介绍了Field II模拟程序的背景和基本特征。它可以模拟任何可以使用单元件或多元件换能器的线性超声系统。可以使用任何类型的变迹、聚焦和激励。解释了该程序使用空间脉冲响应背后的基本理论。描述了合成孔径扩频流量系统的仿真示例。展示了如何设置高级编码激励，以及如何使用 32 个 CPU Linux 集群并行化仿真以将仿真时间从 17 个月减少到 391 小时。
The background and basic features of the Field II simulation program are described. It can simulate any linear ultrasound system, which can use single or multi-element transducers. Any kind of apodization, focusing, and excitation can be used. The basic theory behind the program's use of spatial impulse responses is explained. A simulation example for a synthetic aperture spread spectrum flow systems is described. It is shown how the advanced coded excitation can be set up, and how the simulation can be parallelized to reduce the simulation time from 17 months to 391 hours using a 32 CPU Linux cluster.
