   Sammanfattning : Objectives: This thesis aimed to the evaluation of different digital intraoral radiographic systems, partly by defining objective measures of their physical properties, namely their resolution, signal and noise characteristics, and partly by employing methods to measure their psychophysical properties including viewer performance, such as the Perceptibility Curve test. In a next step, a mathematical model was developed to predict Perceptibility Curves without employing viewers. LÄS MER
