摘　　要：在医学辅助教学或临床诊疗中,为了帮助研究人员对人体内部信息的观察和检测,需要对医学CT数据进行三维可视化。针对这一情况,为了更好地实现医疗三维可视化效果,提出以可视化工具包VTK和VC++6.0为开发平台,并对可视化工具VTK的基本组成、可视化原理和流程进行了研究分析,采用面绘制的Marching Cubes算法和体绘制的Ray Casting算法对医学CT图像三维可视化。实验结果表明,采用上述算法对CT图像进行可视化能够得到很好的重建效果。In medical computer assisted instruction and clinical diagnosis,3D visualization of medical CT data can help researchers to observe and detect the internal information. In view of this,in order to achieve better visual effect of medical CT images,we propose an development platform based on visualization toolkit and VC ＋ ＋ 6. 0,and analyze the basis composition and the principle of VTK. Marching Cubes algorithm of surface render and Ray Casting algorithm of volume render are used to realize 3D visualization of CT images. Experimental results show that this algorithm can effectively obtain the good 3D reconstruction effect of CT images.
