The interpretation of panoramic radiographs requires an understanding of the formation of real and ghost images in rotational panoramic radiology. This article illustrates the use of principles of interpretation in panoramic radiology to identify paraoral soft tissue calcifications, which appear as lesions in the third molar-ramus region of the mandible. The known object rule, a variation of the buccal object rule, is presented as an aid in identifying soft tissue calcifications of the region of the head and neck.
曲面体层片的解读需要理解旋转曲面体层摄影中真实影像和伪影的形成机制。本文阐述了曲面体层摄影解读原则在识别口周软组织钙化中的应用，这些钙化在下颌第三磨牙-下颌支区域表现为病变。已知物体规则作为颊侧物体规则的一种变体被提出，有助于识别头颈部区域的软组织钙化。
