Abstract

Objectives: To derive and test a simplified method to construct Perceptibility Curves (PCs) for dental digital detectors. Methods: Mathematical expressions were derived to make it possible to construct PCs from viewer data obtained at two exposures, one low and one high. PCs were constructed applying these expressions and compared with data previously obtained employing the conventional method. Results: PCs constructed according to the simplified method agree extremely well with conventionally obtained data. Conclusions: Reliable PCs may be constructed according to the simplified method.
