Studies on the hepatic three-dimensional reconstruction and virtual surgery using the hepatic images of the digitized virtual Chinese human female number 1 database / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study digitized virtual hepatic three-dimensional reconstruction and virtual hepatic surgery.</p><p><b>METHODS</b>The whole series of hepatic images taken from the database of digitized Virtual Chinese Human Female Number 1 (VCH-F1) was employed to reconstruct a three-dimensional (3D) liver. First, studied some algorithms for registration of human liver tissue images, and then, segmented the regions of liver, vein, bile duct, and gallbladder from the images. Based on them, the 3D visualization human liver model was reconstructed. Finally, a 3D visualization demo system of liver was developed based on personal computer and Windows operation system.</p><p><b>RESULTS</b>This demo system of liver provided a graphics user interface to rotate, scale the 3D liver to observe the 3D hepatic structure, and a virtual liver simulation system of resection with primary function.</p><p><b>CONCLUSIONS</b>The study may be beneficial to the future research on digitized virtual hepatic and virtual hepatic surgery, and the 3D visualization demo system of liver may be beneficial to the research on the hepatic structure.</p>
