The information yield from a hand-held radiographic unit was compared with that of a conventional dental x-ray unit. Ten observers were asked to detect radiographic details on films taken of a test object at eight different exposure settings with each radiographic unit. The viewers detected significantly more details on three films generated with the experimental unit. No significant difference was demonstrated in the number of details observed with either unit at the remaining exposure settings.
将手持式射线照相设备的信息产出与传统牙科X射线设备的信息产出进行了比较。十名观察者被要求在每种射线照相设备的八种不同曝光设置下，检测拍摄测试对象的胶片上的射线照相细节。观察者在使用实验设备生成的三张胶片上检测到了明显更多的细节。在其余曝光设置下，两种设备观察到的细节数量没有显著差异。
