首例中国数字化可视人体肝门静脉系的三维重建与实时显示

Three dimensional reconstruction and real time display of hepatic portal vein of first Chinese digitized visible human

目的:对中国数字化可视人体及器官的三维重建和实时显示进行技术探索,并为临床和解剖学教学提供精确的肝门静脉系实时三维图形。方法:采用Photoshop图像处理与Surfdriver三维重建相结合方法,在Dell 340工作站上对第三军医大学首例数字化人体断层进行肝门静脉系统的重建,并用Leica QwinV3图像分析系统进行血管分支角度测量。结果:精确显示了肝门静脉系1～3级分支的三维形态,从不同角度观察各分支形态及毗邻关系,前观左右干呈“Y”型夹角110°;右前观右侧三个段支呈三星状、右侧观又呈“T”型。结论:肝内血管的三维重建能立体显示肝门静脉肝内分支在肝叶中的位置,可为临床肝癌等介入治疗提供形态依据。

Objective： To explore the three dimensional reconstruction and real time display of the first Chinese digitalized visible human and organs, so as to provide real time 3D images of the hepatic portal vein for clinics and teaching. Methods： The serial hepatic images of the first Chinese digitalized visible human were reconstructed at Dell 340 Workstation by means of Adobe Photoshop and Surfdriver. Results： Grade 1-3 branches of the intrahepatic portal vein were accurately displayed. Their orientation and adjacent structures could be demonstrated in a real time manner. The angle between left and right trunk of portal vein was 110° at front view. The type was iike “Y”. The 3 branches of right frontal and posterior lobes formed trident of branch at anterior right view, but the character was “T” type at anterior right view. Conclusion： The locations of intrahepatic veins in liver lobes can be clearly observed by 3D surface reconstruction, which can provide morphological data for therapy of liver cancer and liver diseases.
