A Study of Three Dimensional Reconstruction of Hepatic Veins and Intrahepatic Portal Vein Based on the Coronal Sectional Anatomic Dataset
PURPOSE To build the three dimensional (3D) digitized visible model of hepatic veins and intrahepatic portal vein based on the thin coronal sectional anatomic dataset of the liver. MATERIALS AND METHODS A dataset of thin coronal section of the liver was obtained by using the digital freezing milling technique. The pre- reconstructed structures were identified and extracted, and the data were segmented by the method of manual intervention. Using 3D medical visualization software, the visualized model of hepatic veins and intrahepatic portal vein was established. RESULTS The dynamic displaying of the hepatic veins and intrahepatic portal vein continuously at different orientations was realized on PC. The visualized model displayed the complicated adjacent relationship of the hepatic veins and intrahepatic portal vein realistically in 3D space. CONCLUSION High quality 2D images, precise data segmentation and suitable 3D reconstruction method ensure the reality and accuracy of the digital visualized model of hepatic veins and intrahepatic portal vein.
