Abstract
An example of the measurement of detective quantum efficiency is illus trated 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 th e detector, in order to obtain the real DQE (Detective Quantum Efficie ncy).
