The present work introduces an open-source graphical user interface (GUI) computer program called DynamicMC. The present program has the ability to generate ORNL phantom input script for the Monte Carlo N-Particle (MCNP) package. The relative dynamic movement of the radiation source with respect to the ORNL phantom can be modeled, which essentially resembles the dynamic movement of source-to-target (i.e., human phantom) distance in a 3-dimensional radiation field. The present program makes the organ-based dosimetry of the human body much easier, as users are not required to write lengthy scripts or deal with any programming that many may find tedious, time consuming, and error prone. In this paper, we have demonstrated that the present program can successfully model simple and complex relative dynamic movements (i.e., those involving rotation of source and human phantom in a 3-dimensional field). The present program would be useful for organ-based dosimetry and could also be used as a tool for teaching nuclear radiation physics and its interaction with the human body.
本工作介绍了一个名为 DynamicMC 的开源图形用户界面 (GUI) 计算机程序。该程序具有为蒙特卡罗粒子输运程序 (MCNP) 包生成 ORNL 体模输入脚本的能力。可以对辐射源相对于 ORNL 体模的相对动态运动进行建模，这实质上类似于在三维辐射场中源与靶（即人体体模）距离的动态变化。该程序使人体器官剂量学的计算变得更加容易，因为用户无需编写冗长的脚本或处理许多人可能认为繁琐、耗时且容易出错的编程。在本文中，我们已经证明，该程序可以成功地对简单和复杂的相对动态运动进行建模（即，涉及三维场中源和人体体模的旋转）。该程序将对器官剂量学有用，也可作为教授核辐射物理及其与人体相互作用的工具。
