Information yield from a hand-held dental x-ray unit.
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.
