基于Pipeline体系结构的三维PACS图像终端系统

The 3D PACS Image System Based on Pipeline Framework

提出了一种基于Ｐｉｐｅｌｉｎｅ体系结构的图像渲染系统，用于医学图像的处理与绘制。相比于传统的分为体绘制和面绘制的计算机图形学算法，该体系结构能有效的将诸多图形与图像处理方法综合在一起，并且明确的将这些方法与Ｖｅｒｔｅｘ Ｂｕｆｆｅｒ、Ｐｉｘｅｌ Ｂｕｆｆｅｒ和Ｔｅｘｔｕｒｅ Ｂｕｆｆｅｒ相链接起来，并入Ｐｉｐｅｌｉｎｅ体系结构。在该体系结构上，实现了三维组织提取显示（ＳＳＤ显示方式）、最大密度投影显示（ＭＩＰ）、数字重建图像（ＤＲＲ）、三维空间断层显示（ＭＰＲ）、三维空间曲面切割（ＣＰＲ）和交互式虚拟内窥镜（ｉＶＥ）等多种功能，并将其应用在所开发的三维ＰＡＣＳ图像终端系统上。

We put forward an image rendering system based on pipeline framework for processing and displaying medical images.Compared to original computer graphics algorithms divided into volume rendering and surface rendering, this framework can effectively comprehend methods of computer graphics and image processing, import some new concepts such as vertex buffer, pixel buffer and texture buffer. We implement Shaded Surface Display, Maximum Intensity Projection,Digitally Reconstructed Radiography, Multi planar Reformation, Curved Planar Reformation and Interactive Virtual Endoscopy in our new developed PACS image system.
