A three-dimensional virtual endoscopy rendering of a lumen of a tubular structure is based on both non-spectral and spectral volumetric imaging data. The three-dimensional virtual endoscopy rendering includes a 2-D image of a lumen of the tubular structure from a viewpoint of a virtual camera of a virtual endoscope passing through the lumen. In one instance, the three-dimensional virtual endoscopy rendering is similar to the view which is provided by a physical endoscopic video camera inserted into the actual tubular structure and positioned at that location. The non-spectral volumetric image data is used to determine an opacity and shading of the three-dimensional virtual endoscopy rendering. The spectral volumetric image data is used to visually encode the three-dimensional virtual endoscopy rendering to visually distinguish an inner wall of the tubular structure and structure of interest on the wall. 管状结构管腔的三维虚拟内窥镜呈现基于非谱和谱体积成像数据。所述三维虚拟内窥镜呈现包括从穿过管腔的虚拟内窥镜的虚拟相机的视点的管状结构的管腔的2D图像。在一种情况下，所述三维虚拟内窥镜呈现类似于由插入实际管状结构并定
