摘　　要：本文设计实现了一种三维可视化系统,针对60Co集装箱CT检测系统的数据采集、CT图像重建等过程特点,采用了Ray Casting体绘制的三维显示模式。其绘制子系统不影响CT检测系统在研发过程中其它子系统的改进,方便了各子系统功能的完善与扩展。此三维可视化系统在60Co集装箱CT检测系统中的实验效果较好,可以辅助安检人员检测,提高检测效率。60↑Co γ-ray container inspection system（TC-Scan）,developed at Institute of Nuclear and New Energy Technology（INET） of Tsinghua University,is installed at the customs for air-cargo or mega-object inspection against smuggling and prohibited objects.With the development of computer science and technology,3D visualization technology applied to CT inspection system becomes a hotspot.In this paper,a volume rendering visualization system is designed and implemented for TC-Scan,based on ray-casting algorithm.In order to keep flexibility and compatibility for further development,the 3D rendering subsystem is independent from acquisition and reconstruction subsystems.Final rendering results demonstrate legible and distinct 3D vision for container inspection,which improves inspection validity.
