On the basis of phantom experiments, patient doses from radiography at different tube voltages were estimated, and effect of elevated tube voltages on quality of film image was studied.
作者以体模实验为基础，测定了不同管电压拍摄胸片时的病人剂量，考察了提高管电压对胶片影像质量的影响。

The image quality of real-time radiography, however, can not be as good as that of film, and its sensitivity is relatively low.
但目前的射线实时成像检测技术在成像质量等方面与射线照相法有一定差距，检测灵敏度相对较低。

The standard is applicable to the classification of the film systems (combination of film and film processing) for industrial radiography and the control of film processing.
