Abstract
Focuses on the construction of perceptibility curves for given calibration settings in order to define psychophysical properties of the Digora storage phosphor system used in oral radiography. Evaluation of effects of automatic exposure correction on those curves; Caliberation of the Digora system at two exposures to construct those curves; Determination of psychophysical properties of the system by employing registered exposures from a dose-response function with automatic exposure correction off.
