基于曲率特征分析的小儿颅骨畸形重建技术
Pediatric craniosynostosis reconstruction using surface curvature feature analysis
摘要
Abstract
Pediatric craniosynostosis affects the appearance and growth of the child,and leads to contacting pains,easy angry and anxiety,so surgical treatment of skull reconstruction is required for this disease.At present,because of lacking of objective shape of a standard head,the reconstruction planning mainly depends on the surgeon's experi-ence,which usually takes long surgical time and gets low quality reconstruction outcomes.Aiming at this problem,utilizing the principle curvature and Gauss curvature distributions as feature parameters,shape feature analysis of normal skull surface is conducted,and curvature value distribution extents of different surface regions are acquired.The effects of different contact structures and bone flap parameters on the mechanical properties of the reconstructed model are studied through finite element and physical simulation tests.For specific case,the 3D model of the skull is reconstructed based on the CT images,and the curvature analysis is performed by making a comparison with the distribution of the normal skull curvature.After designing and printing out the surgical templates,the reconstruction surgeries are conducted efficiently with the guiding of 3D printed templates.The results show that the ultra-Gaussi-an curvature of the frontal bone is-0.052 00 and 0.000 23 before the operation,and it is reduced to normal after the operation.The efficiency of skull reconstruction and the effect of shape recovery have been significantly im-proved.关键词
