A measurement regime for the determination of the Detective Quantum Efficiency (DQE), an expressive, complex quantity for the characterisation of imaging systems, was developed for digital x-ray imaging systems. A measurement stand was built up that served to test and to characterise the measurement techniques. The measurement stand was used to perform measurements of the DQE of different clinical x-ray imaging systems.
