基于“中国数字人”切片和CT数据重建下颌骨的对比研究

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

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。

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.
