摘　　要：目的探讨小型猪肾脏血管的三维可视化建模方法及其应用意义。方法选取1对新鲜正常离体小型猪肾脏,分别采用"环氧树脂-氧化铅"填充剂灌注腹主动脉(红色)和"环氧树脂-二氧化钛"填充剂灌注后腔静脉(黄色,结扎右肾静脉)并制作铸型,然后行128层螺旋CT薄层扫描采集二维图像数据集,利用Mimics 19. 0软件进行血管阈值分割和重建小型猪肾脏血管三维可视化模型。结果利用Mimics 19. 0软件成功重建小型猪肾脏血管三维可视化模型,该模型肾动、静脉血管的分布及走行与其铸型标本相一致。且通过血管阈值分割来显示肾动、静脉或单独显示肾动脉,效果较为理想,立体感强。结论基于血管铸型标本重建有效分割的小型猪肾脏血管三维可视化模型,为泌尿外科研究和手术虚拟训练奠定仿真平台基础和提供重要的指导意义。Objective To explore a three-dimensional visualized modeling method of miniature pig model of renal vasculature and the value of its application.Methods A pair of fresh normal miniature pig kidneys was selected,and to fill the abdominal aorta with epoxy resin-lead oxide(red)and the posterior cava vein(ligation of the right renal vein)with epoxy resin-titanium dioxide(yellow)for casting.Then128layer spiral CT thin layer scanning was applied to obtain a twodimensional image data set of the casted specimens to segment and reconstruct the three-dimensional visualization model of miniature pig renal vasculature using Mimics19.0software.Results Using Mimics19.0software,we reconstructed a three-dimensional visualization model of miniature pig renal vasculature.The distribution and walking tracks of the renal artery and vein in this model were in accordance with the casted specimens.The renal artery and vein were separately displayed by vascular threshold segmentation.The effect was ideal and the three-dimensional sense was strong.Conclusions A three-dimensional visualization model of miniature pig renal vasculature is reconstructed based on casted specimens and effective segmentation.It may provide a simulation platform and important guidance for research and virtual training in urology.
