Shin DS, Chung MS, Lee JW, Park JS, Chung J, Lee SB, Lee SH - J. Korean Med. Sci. (2009)

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 9: Combined surface models of the liver and neighboring structures, which are rotated.

Mentions: The combined surface models included not only the liver structures but also the stomach, duodenum, muscles, bones, skin, and so on (Table 1). Each surface model was shown with its original shape and location preserved (Fig. 5, 6), because the outlines of structure were stacked with both horizontal-vertical ratio and proper location preserved (Fig. 1) (8). The surface models kept smoothed surface of the structures because medical experts drew outlines of structures (Fig. 1A) and carefully elaborated the surface models (Fig. 2E, 3D). Surface model of the liver was morphologically similar to the volume model (Fig. 8, 9), because both were created from the same origin of the serially sectioned images and segmented images. The result implied that the surface models, volume models, serially sectioned images, and segmented images could be superimposed on one another (Fig. 4B).
