Application value of three-dimensional virtual liver in ultrasonographic classification of liver segment

目的探讨肝脏三维可视化模型在肝脏超声影像学肝段划分中的价值。方法选取中国可视化人体数据集的肝脏连续断面部分,运用体数据绘制与表面绘制的重建方法,在三维可视化软件上建立肝脏三维可视化模型,进一步建立虚拟Couniaud肝段模型,对超声常用切面进行肝段划分。结果肝脏三维可视化模型能够清晰显示肝内管道系统的三维走行分布,建立了虚拟Couniaud肝段模型,并在任意切割面能准确划分出肝段。结论肝脏三维可视化模型能为肝脏超声影像学的肝段划分提供精确的二维和三维解剖学基础,有利于提高超声对肝内病变进行准确定位的能力。

Objective To study the value of the model of three-dimensional visible liver in ultrasonographic classification of liver segment. Methods The sectional images of liver selected from the Chinese visible human data set were used to estab lish the model of 3D visible liver by the volume rendering and the surface rendering reconstruction with 3D visible software. The virtual model of hepatic Couniaud segments was estabished and used to study the hepatic segments classification of the standard ultrasonographic sections. Results The model of 3D visible liver could clearly display the structure of hepatic vessels and their special relationship, and the virtual model of hepatic Couniaud segments was established, which was useful for accurately classifying the hepatic segments. Conclusion The model of 3D visible liver can provide accurate two dimensional and 3D monphological data for uhrasonography in hepatic segments classification. It is helpful for accurate ultrasonographic localization for hepatic diseases.
