自动X线头影测量分析系统的研究

介绍了一个自动X线头影图像测量分析系统。该系统主要包括病例信息管理、标志点自动提取、测量分析、人机交互4个功能模块。在提取标志点的过程中，本系统运用了多种图像处理方法，包括小波多尺度分析和Canny滤波技术，并采取基于知识的边缘跟踪技术提取出头影图像中软硬组织的特征边缘，然后使用有关人脸面部结构的解剖知识，识别出标志点。试验结果表明，本系统能很好地完成X线头影测量分析的功能。

Automatic X-ray cephalometric measuring and analysis system

A system is introduced, which can automatically measure and analyze a cephalogram. This system includes the patient information management module, the landmarking module, the measuring and analysis module, and the inter-active module. Several image processing methods are used in the course of landmarking, such as wavelet multi-scale analysis and Canny filter. A knowledge-based edge-tracing algorithm also is used to detect edges. Landmarks are detected according to the facial anatomy knowledge. The experimental result shows that the system has good performance.
