通过以类似于内窥镜检查的方式浏览 3D 放射图像，可以从 3D 放射图像中获得复杂的解剖信息。然而，需要实时计算“虚拟”内窥镜视图以实现交互式导航。我们提出了一种快速体积渲染方法来计算此类视图。我们的方法受时间相干概念的启发，以交互式帧速率执行动态体积渲染。结果证明了该方法的效率和准确性。此外，我们的方法构成了我们设计的完整虚拟内窥镜系统的一部分。该系统用于 3D 肺部分析。
Complex anatomical information can be obtained from a 3D radiologic image by navigating through it in a manner similar to an endoscopic examination. Real-time computation of ‘virtual’ endoscopic views, however, is needed to permit interactive navigation. We present a fast volume-rendering method for computing such views. Our method, motivated by the temporal-coherence concept, performs dynamic volume rendering at interactive frame rates. Results demonstrate the method's efficiency and accuracy. Also, our method constitutes part of a complete virtual-endoscopic system we have devised. This system is illustrated for 3D pulmonary analysis.
