3D可视化技术在盆腔血管研究中的应用及意义

目的:探讨应用3D可视化技术对盆腔血管进行三维模型构建及研究。方法:采用氧化铋+聚乙烯醇造影填充剂进行新鲜尸体盆腔血管灌注,X线摄影,经CT扫描采集数据导入计算机Mimics10.01或3d-Doctor软件进行血管三维模型构建。结果:构建的盆腔血管三维模型图像清晰,管道饱满,立体空间感强;膀胱、子宫、直肠等动脉均显示出3～4级血管网,各级分支血管的形态、走行、分布及各动脉间的吻合显影清晰,盆腔器官血液供应血管来源,及各血管间的毗邻位置关系清晰明确。结论:采用3D可视化技术可构建理想的盆腔血管网模型,为临床医生对盆腔血管疾病的诊疗提供了新技术。

Application of three-dimensional visualization technology in research of pelvic vessels

Objective：To investigate the feasibility of three-dimensional model construction of pelvic cavity blood vessels with 3D visualization technology.Methods：X-ray and CT scan of pelvic vessels in fresh corpse were taken after perfusion of visualization filler of oxy-bis and polyvinyl alcohol,the obtained data were processed with Mimics10.01 or 3d-Doctor software for three-dimensional model construction.Results：The constructed three-dimensional model of the pelvic cavity blood vessels were clearly shown with good stereopsis,3-4 degree vascular nets of bladder,uterus,rectum etc.were all clearly displayed,distribution and arteria anastomosis of the branch arteries,and the syntagmatic relations among the pelvic vessels were also clear.Conclusions：An ideal three-dimensional model of the pelvic cavity vascular net can be established with 3D visualization technology,which guarantee a new methodology for the treatment of relevant diseases.
