Geant4 是一种蒙特卡罗代码，广泛应用于医学物理领域，具有广泛的应用，例如剂量测定、微米和纳米剂量测定、成像、辐射防护和核医学。 Geant4 正在不断发展，因此拥有一个系统来根据参考数据对医学物理蒙特卡罗代码进行基准测试并执行回归测试至关重要。为了满足这些需求，我们开发了G4-Med，这是Geant4针对医学物理的基准测试和回归测试系统，目前包括18个测试。它们的范围从基本物理量的基准测试到医学物理应用中典型的蒙特卡罗模拟设置的测试。预先构建的 Geant4 物理列表中的电磁和强子物理过程和模型均经过测试。 G4-Med 中包含的测试是通过使用在 CERN 为 Geant4 测试而开发的 geant-val Web 应用程序在 CERN 计算基础设施上执行的。物理观测值可以与参考数据进行比较以进行基准测试，也可以与以前的 Geant4 版本的结果进行比较以进行回归测试。本文描述了 G4-Med 中包含的测试，并显示了根据参考数据对 Geant4 10.5 进行基准测试得出的结果。本文提出和讨论的结果将帮助用户根据其特定应用定制物理列表。
Geant4 is a Monte Carlo code extensively used in medical physics for a wide range of applications, such as dosimetry, micro- and nano- dosimetry, imaging, radiation protection and nuclear medicine. Geant4 is continuously evolving, so it is crucial to have a system that benchmarks this Monte Carlo code for medical physics against reference data and to perform regression testing. To respond to these needs, we developed G4-Med, a benchmarking and regression testing system of Geant4 for medical physics, that currently includes 18 tests. They range from the benchmarking of fundamental physics quantities to the testing of Monte Carlo simulation setups typical of medical physics applications. Both electromagnetic and hadronic physics processes and models within the pre-built, Geant4 physics lists are tested. The tests included in G4-Med are executed on the CERN computing infrastructure via the use of the geant-val web application, developed at CERN for Geant4 testing. The physical observables can be compared to reference data for benchmarking and to results of previous Geant4 versions for regression testing purposes. This paper describes the tests included in G4-Med and shows the results derived from the benchmarking of Geant4 10.5 against reference data. The results presented and discussed in this paper will aid users in tailoring physics lists to their particular application.
