传统雕刻技术与现代三维构建技术联合显示肝内管道系统

目的采用传统雕刻技术与现代三维重建技术联合显示肝内管道。方法选取6例新鲜成人肝脏,先用生理盐水经插管冲洗后,用含5%氧化铅的各色铸型灌注材料经各个管道系统插管注入,放在CT机下扫描,获取CT数据后,数据经minics 10.0软件中进行肝脏管道结构的三维重建,扫描后的肝脏标本采用传统雕刻镂空手法进行处理,制作肝内管道铸型标本。结果三维重建图像中肝内管道清晰、三维立体感强烈,可在重建窗口进行前后、左右、上下三维动态观察其管道走形。制作的一系列肝内管道铸型标本,构型美观、色泽鲜艳、层次清晰,实物立体感强。结论传统雕刻技术与现代三维构建技术联合显示肝内管道系统,既能清晰显示其位置走形,又能制作肝内管道铸型标本,一举两得,满足临床与教学双需要。

Objective To display intraheptic vessels with the combination of traditional sculpture skills and modern three-dimensional reconstruction technologies. Methods 6 fresh adult livers were selected and washed through intubations with physiological saline. After that,they were injected Casting and pouring materials of various colors which contain 5%of lead oxide through the vessel system with intubations, and scanned under the CT machine to obtain CT data, which were reconstructed in three dimensions with minics 10.0 software. The liver specimens after being scanned were managed with traditional sculpture skills to make intrahepatic vessel casting specimens. Results The intrahepatic vessels displayed in three-dimensional images are clear and stereoscopic. Three-dimensional dynamic observations of the route and form of the vessels can be achieved in the reconstruction window. A series of intrahepatic vessel casting specimens are of artistic configuration, vivid color, clear layers and strong stereoscopic impression.Conclusion The traditional sculpture skills and modern three-dimensional technologies can be combined to display the location, route and form of the intrahepatic vessel system, and to make intrahepatic vessel specimens, which has great significance to meet the clinical and instructional requirement.
