In this article, we present Kinetic Transport Solver for Radiation Therapy (KiT-RT), an open source C++-based framework for solving kinetic equations in therapy applications available at https://github.com/CSMMLab/KiT-RT. This software framework aims to provide a collection of classical deterministic solvers for unstructured meshes that allow for easy extendability. Therefore, KiT-RT is a convenient base to test new numerical methods in various applications and compare them against conventional solvers. The implementation includes spherical harmonics, minimal entropy, neural minimal entropy, and discrete ordinates methods. Solution characteristics and efficiency are presented through several test cases ranging from radiation transport to electron radiation therapy. Due to the variety of included numerical methods and easy extendability, the presented open source code is attractive for both developers, who want a basis to build their numerical solvers, and users or application engineers, who want to gain experimental insights without directly interfering with the codebase.

在本文中，我们介绍了用于放射治疗的动力学传输求解器 (KiT-RT)，这是一个基于 C++ 的开源框架，用于求解治疗应用中的动力学方程，可在 https://github.com/CSMMLab/KiT-RT 上找到。该软件框架旨在为非结构化网格提供一系列经典的确定性求解器，以便于扩展。因此，KiT-RT 是在各种应用中测试新数值方法并将其与传统求解器进行比较的便捷基础。该实现包括球谐函数、最小熵、神经最小熵和离散坐标方法。通过从辐射传输到电子放射治疗的多个测试案例展示了解决方案的特性和效率。由于包含的数值方法多种多样且易于扩展，所提供的开源代码对于想要构建数值求解器的基础的开发人员以及想要在不直接干扰模型的情况下获得实验见解的用户或应用工程师都具有吸引力。代码库。
