Abstract :
An example of the measurement of detective quantum efficiency is illustrated for a scintillating glass optical fiber detector used in X-ray imaging. We have shown the necessity to filter the input Poisson noise of the incoming beam, by the MTF (Modulation Transfer Function) of the detector, in order to obtain the real DQE (Detective Quantum Efficiency).
