摘要
作者介绍了普通Ｘ线片数字减影图像处理系统的组成及功能，并通过对该系统的实验检测，证明该系统对微小的牙槽嵴顶病变、根分歧、根侧及根尖病变的诊断具有重要价值。此外，本文尚对根尖片投照的重复性问题、根尖片数字减影技术原理及其临床应用前景进行了探讨。
AbstractThe composition and functions of digital subtractionsystem for conventional radiographs were introduced.Based on the experimental test for this system, it hasbeen found that digital subtraction system for conven-tional radiographs is very valuable for the diagnoses ofminute bone lesions in the bifurcation =, root side and appli-cal part of the teeth as well as in the alveolar crest. Inaddition, the reproducibility of the projection geometry ,the principle of digital subtraction and its clinical appli-cation prospect are also discussed in the present paper.
