ABSTRACT
Liver three-dimensional simulation technology is a cross-field study of hepatic surgery,anatomy,computer image technology and virtual three-dimensional technology.Compared to the two-dimensional images,the three-dimensional technology applied to the planning of liver surgery has obvious advantages and unique features.This technology not only can three-dimensional clarity of presentation and precise positioning of the important structures of the liver inside and outside,but also allow the surgeon independent dividing a interest region of liver inside and outside.Visualization of the liver and liver volume measurement preoperative planning,can effectively reduce the risk of postoperative liver failure,the remnant liver necrosis and postoperative bile leakage.
