[Abstract]
Objective To build digitized visible model of the liver and intrahepatic vessels of the visual Chinese man,providing morphological data for virtual surgery of liver. Methods The datum collected from the visual Chinese manliver were used with 3D-reconstruction to build digitized visual model of the liver, and to realize the virtual surgery.Results The quality of the computerized 3D-reconstructed model was distinct and perfect. Any diameter and angle ofthe structures reconstructed could be resected conveniently to acquire the object center, surface and volume of hepaticsegment. Conclusions The creation of visual liver model can be used for the digital anatomy teaching, and for thehepatic virtual surgery of hepatic cancer.
