Segmentation and reconstruction of hepatic veins and intrahepatic portal vein based on the coronal sectional anatomic dataset

Abstract

Three-dimensional (3D) reconstruction of intrahepatic vessels is very useful in visualizing the complex anatomy of hepatic veins and intrahepatic portal vein. It also provides a 3D anatomic basis for diagnostic imaging and surgical operation on the liver. In the present study, we built a 3D digitized model of hepatic veins and intrahepatic portal vein based on the coronal sectional anatomic dataset of the liver. The dataset was obtained using the digital freezing milling technique. The pre-reconstructed structures were identified and extracted, and then were segmented by the method of manual intervention. The digitized model of hepatic veins and intrahepatic portal vein was established using 3D medical visualization software. This model facilitated a continuous and dynamic displaying of the hepatic veins and intrahepatic portal vein at different orientations, which demonstrated the complicated relationship of adjacent hepatic veins and intrahepatic portal vein realistically in the 3D space. This study indicated that high-quality 2D images, precise data segmentation, and suitable 3D reconstruction methods ensured the reality and accuracy of the digital visualized model of hepatic veins and intrahepatic portal vein.

Mixed reality navigation training system for liver surgery based on a high‐definition human cross‐sectional anatomy data set

“…Since the Visible Human Project (VHP) appeared in 1995, several studies on 3D reconstruction of virtual liver based on tomographic anatomical datasets have been conducted 5–9 . Advances in sectional anatomy are reflected in the maturity of specimen preprocessing technology, accuracy of milling, camera resolution, and the improvement of software and hardware related to image registration, segmentation and reconstruction 10 .…”
