光学相干断层扫描中图像形成的真实建模，使用麦克斯韦方程对样本中的光传播进行建模，对于培训研究人员和临床医生、图像解释和技术开发等应用非常有用。然而，此类模型需要数值技术的专业知识来求解麦克斯韦方程组和建模光学系统。在这里，我展示了一个免费提供的开源包，旨在使整个光学相干断层扫描社区的研究人员能够访问此类模拟。时域麦克斯韦求解器 (TDMS) 基于有限差分时域 (FDTD) 和伪谱时域 (PSTD) 方法，包括对 OCT 系统中常见的光学系统进行建模所需的功能。 TDMS 包含多个用例示例，旨在使仿真背景有限的用户能够轻松使用该软件包。
Realistic modelling of image formation in optical coherence tomography, which models light propagation in the sample using Maxwell’s equations, is useful for applications such as training researchers and clinicians, image interpretation and technique development. Such models, however, require specialised knowledge of numerical techniques for solving Maxwell’s equations, and for modelling optical systems. Here I present a freely available, open source package, aimed at making such simulations accessible to researchers throughout the optical coherence tomography community. Time Domain Maxwell Solver (TDMS) is based on the finite difference time domain (FDTD) and pseudo spectral time domain (PSTD) methods, and includes functionallity required to model optical systems typically found in OCT systems. TDMS includes several use case examples aimed at making it easy for users with limited background in simulation to use the package.
