摘要 提出了一种基于体绘制模型的医学图像数据场的三维可视化法 :剖切显示法 ,并在微机环境下以人体头部CT图像为例进行了实验。实验证明该方法具有绘制速度快和成像精度高的优点。 A PC based method named CDA (Cutting Display Algorithm) for rendering volumetric image data sets is proposed. In this paper,two kinds of cutting operations,opening and moving,are discussed in detail. The experimental results about CT images show that our approach improves image quality and reduces rendering time.
