Geant4 中的体积可视化驱动程序的开发是为了使用外部体积可视化器在放射治疗模拟中显示复杂的患者图像和计算的剂量分布。蒙特卡罗模拟已广泛应用于放射模拟。在放射治疗模拟中，应用于剂量分布的计算、射束传输系统的优化等。 Geant4 工具包用于为此目的构建模拟器。在该模拟器中，可视化工具需要体积渲染功能来显示复杂的体积数据。然而，Geant4的可视化系统中没有体绘制功能。体积可视化驱动程序提取模拟中的患者数据、计算的剂量分布、粒子轨迹和光束传输模块的几何信息，然后将其信息保存为数据文件。利用该数据文件，外部体积可视化器能够轻松显示模拟结果。
A volume visualization driver in Geant4 was developed in order to display a complex patient image and a calculated dose distribution in a radiotherapy simulation with an external volume visualizer. Monte Carlo simulation has been widely used for radiological simulation. In radiotherapy simulation, it applies to calculation of the dose distribution, optimization of the beam delivery system, and so on. Geant4 toolkit is utilized to build a simulator for that purpose. In that simulator, visualizer needs the volume rendering capability to display a complex volume data. However, there is no volume rendering capability in the visualization system in Geant4. The volume visualization driver extracts a patient data, calculated dose distributions, particle trajectories and geometrical information of beam delivery modules in the simulation, and then saves their information as a data file. With that data file, the external volume visualizer is able easily to display results of the simulation.
