摘要
目的 :采用计算机图象处理技术 ,进行X线颅颌影像硬组织内部结构的自动识别研究 ,为计算机对X线颅颌面影像的全自动识别、定点、测量分析奠定基础。方法 :在头颅定位仪的严格定位下 ,拍摄研究对象的正中咬合位时的X线颅颌侧位片。拍摄的X线片通过扫描仪将图像信息输入计算机并进行图象处理。首先是图象增强 ,随后 ,利用X线颅颌面侧位片图象灰度分布的特征 ,将原始图象分层。最后 ,进行了图象重建。结果 :提取出了部分颅颌硬组织内部结构。结论 :初步建立了计算机X线颅颌面影像硬组织的自动识别 。
Objective:The aim of this article is to study automatic recognition of hard?tissue in cephelometric image by using image?processing technique Methods:The teenagers with normal occlusion wore taken cephalograms in standard posture to get the imaging.The scanner was used to produce digital images of the cephalometric radiographs. Three steps of image processing were used as:①Image enhance;②Image segmentation;③Image reconstruction Results:The tracing of skull structures and some contours of craniofacial hard?tissue structures was obtained.Conclusion:The study shows potential use of this method for the automatic recognition of hard?tissue in cephalograms
