X线图象的数字化处理与计算机测量──牙种植体周围结构X线图象的数字化处理

Computer Digitalization and Measurement of Radiographs Digitalization of Radiographs of Implants and Surrounding Structures

应用计算机图象分析处理系统，对牙种植体周围结构Ｘ线图象进行数字化图象增强处理与计算机测量。图象处理方法包括几何校正、灰度增强、伪彩色增强处理和计算机测量。处理结果提高了原图的结构分辨率，提供了计算机测量数据，从而为牙种植体Ｘ线图象的计算机分析奠定了基础。

Computer aided image analysis and processing system was employed in this study to achieve enhancement and measurement of the digitalized radiographs of implants and surrounding structures. The image processing methods includes: algebraic rectification, gray scale enhancement, pseu-dochromo enhancement and computer measurement, which results in a elevated structural resolution compared with initial radiographs and can provide computer measured data. This study enlightened the computer analysis modality of radiographs of implants and surrounding structures.
