生物组织中的非线性超声波的模拟具有许多重要的应用。然而，这是一个计算密集型的任务，由于大的域大小所需的许多问题的实际利益。最近，开发了一种高效的全波非线性超声模型，并作为开源k-Wave的一部分发布。在这里，这个模型是验证使用一系列的实验测量与线性诊断超声探头和膜水听器。在去离子水和橄榄油中进行测量，后者表现出与人体组织相似的幂律吸收特性。还测试了0°和20°的转向角，传播距离约为数百个声波波长。仿真和实验结果表明，在时域和频域的密切协议。这些结果证明了使用k-Wave工具箱进行非线性超声模拟的定量有效性。
The simulation of nonlinear ultrasound waves in biological tissue has a number of important applications. However, this is a computationally intensive task due to the large domain sizes required for many problems of practical interest. Recently, an efficient full-wave nonlinear ultrasound model was developed and released as part of the open source k-Wave Toolbox. Here, this model is validated using a series of experimental measurements made with a linear diagnostic ultrasound probe and a membrane hydrophone. Measurements were performed in both deionised water and olive oil, the latter exhibiting power law absorption characteristics similar to human tissue. Steering angles of 0° and 20° were also tested, with propagation distances on the order of hundreds of acoustic wavelengths. The simulated and experimental results show a close agreement in both the time and frequency domains. These results demonstrate the quantitative validity of performing nonlinear ultrasound simulations using the k-Wave toolbox.
