8.Clinical application of three-dimensional surface shaded display(SSD)and volumerendering techniques(VRT)of spiral CT during resection and reconstruction of pelvic tumors
9.All patients were performed MSCT scan and images were reconstructed by multiplanar reonstruction (MPR)、maximum intensity projection (MIP)、volumerendering technique (VRT)、surface shaded display (SSD).
10.Volume visualization is a joint between VISC and 3D GIS, the prospect of which is summarized in this thesis. And two basic algorithm on visualization of 3D data are expounded: Surface-fitting method and Direct VolumeRendering(DVR).
