基于"中国数字人"切片和CT数据重建下颌骨的对比研究

目的：探索快速重建人体下颌骨三维模型的方法，比较常用CT资料重建与切片资料重建骨组织的优劣差异。方法：获得虚拟人数据集，并取虚拟人数据中下颌骨部分的切片资料和CT资料分别进行软件的三维重建。结果：利用切片资料建立了较之CT资料更为精细准确的人体下颌骨三维模型。结论：采用应用软件重建方法快速可行，而且利用虚拟人的切片数据建立了高度精确的下颌骨三维模型。

Comparison study on the 3D reconstruction of mandible according to Virtual Chinese Human slice data and CT data

To reconstruct 3D model of mandible on the basis of Virtual Chinese Human data and normal CT pictures, and to compare their reconstruction results with each other. Methods: To select mandible data from Virtual Chinese Human slices and normal CT pictures, and reconstruct 3D model of mandible respectively by using special software. Results: A 3D model of mandible was reconstructed accurately by adopting virtual human slice data. Conclusions: To reconstruct 3D digital model of human bone by specific software is a beneficial way for our research. The 3D mandible model reconstructed by adopting virtual human slices is more accurate than that by adopting CT pictures.
