mSOUND是一个用MATLAB编写的开源工具箱。该工具箱用于模拟具有任意非均匀性的介质（主要是生物组织）中的线性/非线性声波传播，其中声速、密度、衰减系数、幂律指数和非线性系数都是空间变化的函数。计算模型是基于混合域方法的迭代单向模型。在本文中，沿着三个有代表性的例子来说明如何使用mSOUND建立模拟的一般准则。第一个例子使用瞬态混合域方法（TMDM）的前向投影计算瞬态声场为一个给定的源定义在一个平面上。第二个例子使用特定频率的混合域方法（FSMDM）的前向投影，以快速获得直接在感兴趣的频率的压力分布，假设线性或弱非线性波传播。第三个例子演示了如何使用TMDM后向投影来重建初始声压场，以促进光声层析成像（PAT）。mSOUND（https：//m-sound.github.io/mSOUND/home）旨在补充现有的超声建模工具箱，预计可用于医疗超声领域的广泛应用，包括治疗计划、PAT、换能器设计和表征。
mSOUND is an open-source toolbox written in MATLAB. This toolbox is intended for modeling linear/nonlinear acoustic wave propagation in media (primarily biological tissues) with arbitrary heterogeneities, in which, the speed of sound, density, attenuation coefficient, power law exponent and nonlinear coefficient are all spatially varying functions. The computational model is an iterative one-way model based on a mixed domain method. In this paper, a general guideline is given along with three representative examples to illustrate how to set up simulations using mSOUND. The first example uses the transient mixed-domain method (TMDM) forward projection to compute the transient acoustic field for a given source defined on a plane. The second example uses the frequency-specific mixed-domain method (FSMDM) forward projection to rapidly obtain the pressure distribution directly at the frequencies of interest, assuming linear or weakly nonlinear wave propagation. The third example demonstrates how to use TMDM backward projection to reconstruct the initial acoustic pressure field to facilitate photoacoustic tomography (PAT). mSOUND (https://m-sound.github.io/mSOUND/home) is designed to be complementary to existing ultrasound modeling toolboxes and is expected to be useful for a wide range of applications in medical ultrasound including treatment planning, PAT, transducer design and characterization.
