[Three-dimensional reconstruction research on Mingmen (GV 4)].
OBJECTIVE
To show the space structures of Mingmen (GV 4) area and its adjacent tissues.


METHODS
A frozen female corpse was cut into about 0.5 mm thick sections with a high-speed steel plane machine and photographed with digital and optical camera. Two 2-D transverse phase picture data sets were obtained and then were sequenced, matched, modified and divided. The 3-D reconstruction software was used to reconstruct the outline form of the lumbar part containing Mingmen (GV 4) to attain transverse phase picture data sets (3 022 sheets, 0.57 mm in thickness). The sagittal, coronal and different oblique plane were cut and the tissue structures in these pictures were analyzed. Thus, the reconstruction data sets were obtained.


CONCLUSIONS
After the structures of Mingmen (GV 4) were reconstructed with computer, the form of Mingmen (GV 4) can be dynamically observed from any angle and the space construction law of gross form of Mingmen (GV 4) can be proved.
