摘要

傳統的測顱分析是使用描圖紙在測顱X光片上定出界標(landmark)，再測量出所需要的長度和角度，而在X光片逐漸數位化以及數位化測顱分析法出現後，增加了許多便利性，同時也節省了很多在測量上所花的時間。然而，文獻上比較數位化和傳統測顱分析法的報告卻不多，本文即針對兩種方法所需的時間，以及測量上的可信賴度(reliability)和再現性(reproducibility)，進行文獻回顧及整理。

The procedures of conventional cephalometric analysis included tracing on the tracing paper, landmark identification, and angular and linear measurement. However, conventional cephalometric analysis was gradually taken the place by digitization of radiographic films and cephalometric analysis, which reduce the radiation burden, the operational costs, the environmental burden, and most importantly, save the time. The aim of this article is to review the related studies comparing digitized and conventional cephalometric radiographs with respect to reproducibility of angular and linear measurements or accuracy of landmark identification.
