本文描述了一种将射线投射与分段管状物体（例如血管）相结合的新方法，以实现临床有用的显示。该方法首先使用修改后的 z 缓冲区投影分段管，该缓冲区还记录有关投影对象的信息。后续步骤仅通过 z 缓冲区记录的对象体积选择性地进行体积渲染。与传统的“块”体积渲染一样，显示实际图像数据，当分割对象的边界不确定时，这一点很重要。与传统的“块”体积渲染不同，该方法允许用户操纵对象，操作快速，甚至可以为最大强度投影提供深度信息。尽管我们的方法是为显示脑内脉管系统而开发的，但该方法适用于整个身体管状物体的体积渲染。
This paper describes a new method of combining ray casting with segmented tubular objects, such as blood vessels, for purposes of clinically useful display. The method first projects segmented tubes using a modified z-buffer that additionally records information about the objects projected. A subsequent step selectively volume renders only through the object volumes recorded by the z-buffer. In common with traditional "block" volume rendenng the actual image data is shown, of importance when the boundary of a segmented object is uncertain. Unlike traditional "block" volume rendering, the approach permits user manipulation of objects, operates rapidly, and provides depth information even for maximum intensity projection. Although our methods were developed for display of the intracerebral vasculature, the approach is applicable to volume rendermg of tubular objects throughout the body.
