为比较计算机辅助数字头影测量法和传统手工描绘法标志点定位间的差异,作者进行了以下研究。 材料和方法 从台湾大学附属医院正畸科任意抽取10张头影测量X线片,分析19个常见的头影测量标志点,由7名正畸住院医生在计算机上和原始X线片上进行标志点定位,其间至少间隔一周。计算机辅助数字头影量法用扫描仪(VXR-12,Vidar系统)扫描头影测量X线片,使之转换为数字格式化资料,并显示在高分辨率单铬监视器上,其数字成
In order to compare the discrepancies between the computer aided digital cephalometric method and the traditional hand-drawn method of locating the landmark points, the author conducted the following research. Materials and Methods Ten cephalometric X-ray films were randomly collected from the Department of Orthodontics, National Taiwan University Hospital, and 19 common cephalometric markers were analyzed. Seven orthodontic residents were marked on the computer and the original radiographs Point positioning, during at least a week interval. Computer-Aided Digital Cephalometric Scanned cephalometric X-ray with a scanner (VXR-12, Vidar system) to convert it to digitally formatted data and displayed on a high-resolution mono-chrome monitor with digital
