摘要

目的　构建腰椎智能医学图像建模系统，替代分析人员完成有限元建模过程中对腰椎活动度的繁复计算工作。方法　利用python语言构建一个附和系统，包括录制程序与回放程序。通过Geomagic的偏差分析功能评估智能建模与人工建模二者的偏差分布，并分别构建腰椎的非线性有限元模型，验证模型对有限元分析结果的影响。结果　本课题建立智能腰椎复位系统，成功构建腰椎体的三维模型。与人工建模进行偏差分析，超过98%的区域0偏差。有限元活动度存在些许差异，经配对t检验，差异无统计学意义（P=0.2）。结论　利用智能建模系统构建的三维腰椎模型，精确度较高且对有限元分析结果未产生影响。

Abstract

Objective　To construct a lumber intelligent medical image modeling system and replace the analyst to finish the calculation work of lumbar mobility during finite element modeling.　Methods　Echo system including recording programs and playback programs were built by using the python language. In addition, the Geomagic deviation analysis function was used to evaluate the deviation distribution of intelligent modeling and artificial modeling. The nonlinear finite element model of the lumbar spine was constructed respectively to verify the influence of the model on the finite element analysis results.　Results　The intelligent lumbar reduction system was established and the 3D model of lumbar vertebral body was successfully constructed. Deviation analysis was carried out between the intelligent modeling and artificial modeling. More than 98% of the region achieved zero deviation. There were some differences in the finite element activity at first, but after paired t-test, there was no statistical difference (P=0.2).　Conclusions　The 3D lumbar spine model constructed by the intelligent modeling system has high accuracy and no impact on the analysis results of finite element.
