A comparison of the radiation doses for xeroradiographic and conventional film screen cephalography was made. Alderson tissue-equivalent phantoms were used for patient stimulation. An optimum technique in terms of patient dose and imaqe quality was established for the xeroradhe data indicated that the dose for the Xerox process ranged from five to eleven times greater than that for the conventional process for entrance and exit exposures, respectively. The most commonly reported dose, the entrance dose, was found to be 206 mrad, which is five Imes that for the conventional cephalogram. This dose, however, falls within an acceptable range for other dental and medical radiation doses. It is recommended that conventional cephalography be used for routine purposes and that xeroradiography be reserved for situations requiring the increased image quality that the process affords.
对干板X线摄影和传统屏片头颅摄影的辐射剂量进行了比较。使用奥尔得森组织等效体模模拟患者。就患者剂量和图像质量而言，为干板X线摄影建立了最佳技术。数据表明，就入口和出口照射而言，静电复印过程的剂量分别比传统过程大5至11倍。最常报告的剂量，即入口剂量，为206毫拉德，是传统头颅造影剂量的5倍。然而，该剂量在其他牙科和医学辐射剂量的可接受范围内。建议常规头颅摄影用于常规目的，而干板X线摄影则保留用于需要该过程所提供的更高图像质量的情况。
