基于GVF Snake模型的骨密度测定研究

Study of bone mineral density measurement based on GVF Snake model

目的探讨GVF Snake模型在骨密度测定中的价值。方法本文将GVF Snake模型应用于目标区域分割,并与区域分割法进行对比。结果实验表明梯度矢量流模型有较好的健壮性和实用性,分割结果与实际边界非常吻合。结论GVF Snake模型为一种很实用的分割方法,能够应用在骨密度测定中。

Objective To investigate the potential of GVF Snake model in measuring bone mineral density.Methods the Gradient Vector Flow model and the Region Growing method were applied in segmentation of the middle phalanges image and aluminum wedge image separately in this paper.Then,the results were compared.Results The experiments showed that GVF Snake model was not only robust and practicable,but also segmentation results were in line with the actual border.Conclusion GVF Snake model is very useful,and can be widely used in measuring bone mineral density.
