Abstract

It is shown, that the Image Quality parameters, Modulation Transfer Function (MTF) and noise can be evaluated digitally with high accuracy. The systems MTF is measured by the use of a 5 slits phantom. Simulation studies are showing the optimal phantom dimension and indicate the expected precision of the measurement. By comparison studies with conventional techniques the MTF measurement procedure is validated for the effects of pixel coarseness, noise and limiting resolution. An analytical expression for signal-to-noise ratio in a digital radiographic system is developed. Predicted values are compared with measured data.
