The present study showed that the thyroid (60X) and active bone marrow (100X) doses are increased when xeroradiography is used in cephalometrics, as compared to a rare earth screen/film system. These results are compared to previously published articles. The rationale for advocating a kVp setting of approximately 100 and a negative development mode is presented. It is recommended that xeroradiographic cephalometric examinations be reserved for special cases in which image quality is a top-priority requirement.
本研究表明，与稀土增感屏/胶片系统相比，在头影测量中使用干板X线摄影时，甲状腺（60倍）和活跃骨髓（100倍）的剂量会增加。将这些结果与先前发表的文章进行了比较。提出了主张采用约100的千伏峰值设置和负显影模式的基本原理。建议干板X线头影测量检查仅用于对图像质量有最高优先级要求的特殊情况。
