| 摘 要： | 在骨龄评定方面,国内外普遍采用图谱法,这种方法是根据专家的经验,对照标准图谱,定性测定人体的骨龄。此法的缺点是骨龄评定精度受专家的经验、摄影方式和质量的影响较大。特别是正在发育的青少年,现行的骨龄评定方法会带来较大的差异。本文介绍的方法是用X光摄影测量精确测定手腕骨的三维空间位置和大小,据根专家提出的各种骨块在骨龄评定中所占的权重比,利用回归拟合的方法确定这些骨块的空间位置和大小与骨龄之间的关系,综合评判骨龄。根据对82人(分男女两组)采样试验,该方法取得了令人满意的结果。

| Abstract: | The approach of evaluating the age of human's wrist bones using pattern identification is a popular method in China and abroad. The accuracy of this method is greately affected by expert's experience, photogrammetric geometry and quality of X-ray films. In particular it may result in large difference of assessment of teen-agers. This article presents a new approach using X-ray photogrammetry to determine patial locations and size of wrist bones, considering the weights of various bones proposed by experts, employing linear regression to simulate the relationship between their lceations and dimensions and the age of wrist bones for integrated evaluation. 82 teen-agers were chosen as a sample to test the new method. The result of the test was desired. |
