摘　　要：目的:探索应用重金属氧化物填充剂对人体标本血管进行灌注,经CT扫描后进行血管3D可视化重建。方法:采用金属氧化物粉末(氧化铅、氧化铋、氧化铈)与填充载体配制成填充剂进行新鲜尸体血管灌注,X线摄影,CT扫描获得数据集,采用Mimics10.01或3d-Doctor软件进行血管三维重建。结果:金属氧化物造影填充剂灌注的血管标本,X线摄影下标本动脉血管显影清晰,细小血管也充分显示;CT连续扫描断面图像血管显影均匀,三维重建所得图像清晰,管道饱满,边缘连续平滑,无齿状伪影,立体感强。结论:重金属氧化物是一种理想的人体标本管道造影材料,适用于人体血管3D可视化重建。Objective：To investigate the feasibility of 3D visual reconstruction of blood vessels via CT scanning after perfusion of heavy metal oxides fillers. Method： Heavy metal oxides powder and filling carrier were mixed together to perfuse vessels of fresh corpse. X-ray photography and CT scanning were performed to collect data for 3D image reconstruction of these vessels with minics10.01 or 3d-Doctor software. Result： Artery and minute branches of the vessels samples which were peffused with heavy metal oxides were clearly shown in x - ray fihn and CT successive scanning images. They were also well shaped in 3D reconstruction images which were clear, smooth, free of dentate shadow and with strong stereoscopic sensation. Conclusion ： Heavy metal oxides are ideal peffusion materials for 3D visual reconstruction of human vessels.
