Our results have shown that surface rendered models provide valid information of anatomical structures. This model can be used as an interactive 3D-anatomy atlas for fast viewing. Internet based 3D-anatomy atlas can also be supported using Java applet in the near future. 3D texture based volume rendering model provides acceptable rendering speed but with more spatial information. The implementation is fairly easy and supported by several popular graphics APIs. Current SUN graphics card has no hardware support for 3D-texture mapping. The rendering speed can be significantly improved using the graphics card with 3D texture mapping capability. The rendered accuracy is not as optimal at this time. For example, there is connective tissue remaining on the surface of left lung as shown in Figure 12 and Figure 13. This is partially due to bias of segmentation. We believe with image processing technique, the segmentation accuracy can be increased which in turn would results in better rendered 3D structures. The segmentation issues are out of the scope of this paper since our objective is to show the potential uses of VHIF files. We proposed to continue to working with the 3Dsystem database to evaluate and improve the rendering capability in the future.
