基于CT图像的人体颅骨对称性测量与分析

The Measurement and Analyses of Symmetry Characteristic of Human Skull Based on CT Images

提出两种颅骨对称性评价算法,利用活体人头颅CT图像,通过自编程序对图像进行分割与二值化、图像纠偏、边缘提取等处理后,实现颅骨对称性的定量测量。通过对3 000例颅骨CT图像的测量与统计分析,得出人体颅骨的对称性比例和分布,从而为人体头部损伤生物力学建模提供可靠的数据。该测量结果在解剖学、临床医学、生物力学和头部损伤分析等领域有着广泛的应用价值。

Two kinds of algorithm have been set forth to estimate the symmetry characteristic of live human skull on CT image. These CT images were treated with a series of processes such as coding into programs, format- ting originals, binary coding, rectifying image deviation, detecting boundary edge, and quantitatively measuring the skull symmetry. The statistical analyses of measuring 3,000 live human skull images have worked out the ratio and the distribution of the skull symmetry, so that dependable data are provided for establishing the human head injury biomechanics model. The results are of great practical value in the fields of anatomy, clinical medicine, biomechanies study, head injury analysis, etc.
