基于CT图像的人体股骨逆向工程研究

Rebuild human thighbone based on CT image

股骨作为人体重要的组成骨骼有着重要的研究价值,应用逆向工程原理,通过阈值方法对采集于活人的股骨CT图像数据进行选取和边界识别,建立股骨不同扫描层的边界曲线并最终拟合成人体股骨模型。对该模型选取光滑系数进行后处理,得到较理想的三维模型,可以将模型导入后续有限元分析软件进行分析。

This work reconstruct the living human femur through CT images by using reverse engineering. The different point compare with other reconstruct method is threshold has the most important power during boundary selection. In order to analyze mechanics characters of femur through finite element method smooth the model must be complete before import model into software.
