Bottom Line: From the segmented images, serial outlines of each structure were stacked; on the popular commercial software, advanced surface reconstruction technique was applied to build surface model of the structure.A surface model of the liver was divided into eight models of hepatic segments according to distribution of the portal vein.The surface models will be distributed to encourage researchers to develop the various kinds of medical simulation of the abdomen.

ABSTRACT
Unlike volume models, surface models, which are empty three-dimensional images, have small file size, so that they can be displayed, rotated, and modified in a real time. For the reason, the surface models of liver and neighboring structures can be effectively applied to virtual hepatic segmentectomy, virtual laparoscopic cholecystectomy, and so on. The purpose of this research is to present surface models of detailed structures inside and outside the liver, which promote medical simulation systems. Forty-seven chosen structures were liver structures such as portal triad, hepatic vein, and neighboring structures such as the stomach, duodenum, muscles, bones, and skin. The structures were outlined in the serially sectioned images from the Visible Korean Human to prepare segmented images. From the segmented images, serial outlines of each structure were stacked; on the popular commercial software, advanced surface reconstruction technique was applied to build surface model of the structure. A surface model of the liver was divided into eight models of hepatic segments according to distribution of the portal vein. The surface models will be distributed to encourage researchers to develop the various kinds of medical simulation of the abdomen.

Figure 8: Volume model of the liver, which is rotated.

Mentions: As the preliminary trial of volume reconstruction, both intervals and pixel size of serially sectioned images were increased from 0.2 mm to 1 mm; by the help of the segmented images, outside of the liver in all serially sectioned images were simultaneously erased on Photoshop. On 3D-Doctor software, the serially sectioned images were stacked and reconstructed by volume modeling to acquire a volume model of the liver with 1×1×1 µL voxels and real color. It was then rotated (Fig. 8).
