Monte Carlo (MC) simulations play an important role in radiotherapy, especially as a method to evaluate physical properties that are either impossible or difficult to measure. For example, MC simulations (MCSs) are used to aid in the design of radiotherapy devices or to understand their properties. The aim of this article is to review the MC method for device simulations in radiation therapy. After a brief history of the MC method and popular codes in medical physics, we review applications of the MC method to model treatment heads for neutral and charged particle radiation therapy as well as specific in-room devices for imaging and therapy purposes. We conclude by discussing the impact that MCSs had in this field and the role of MC in future device design.
蒙特卡罗（MC）模拟在放射治疗中起着重要作用，特别是作为评估物理性质的一种方法，这些物理性质要么不可能测量，要么难以测量。例如，MC 模拟（MCS）用于辅助放射治疗设备的设计或帮助理解它们的特性。本文的目的是回顾 MC 方法在放射治疗中的设备模拟。在简要介绍 MC 方法和医学物理中的流行代码的历史之后，我们回顾了 MC 方法在模拟中性和带电粒子放射治疗的治疗头以及用于成像和治疗目的的特定室内设备方面的应用。最后，我们讨论了 MCS 在该领域的影响以及 MC 在未来设备设计中的作用。
