面向数字接骨板设计的长骨模型几何分析
Geometric analysis of 3D long bone models for digital bone plate design
摘要
Abstract
As a common medical equipment to fix fractured bones, bone plate is supposed to be closely fit with bones. However, until now, the designs of bone plates are mostly based on clinical experience, or just take a few bone geometries as references, which cannot be tightly fit with bones and does not meet most patients’requirements. In this paper, an approach to obtain a series of“average bones”from the 3D model set of the bones is proposed, which lays a foundation for serial design of bone plates. The approach first adopts Coherent Point Drift non-rigid registration algorithm and Laplacian-coor-dinate-based mesh deformation algorithm, re-meshing the bone-data to be topology-consistent, and then process by principal component analysis and cluster analysis. Experiments results show that bone plates, manufactured in accordance with such series of“average bones”, can significantly better fit the broken bones, and meet the requirements of practical application.关键词
