Paper Abstract

The modulation transfer function, noise power spectrum and sensitometric response which are the most significant parameters for characterising the image information transfer efficiency of screen-film systems have been determined experimentally on various systems used in medical X-ray diagnosis. By use of an equation introduced by Dainty and Shaw /2/ the Detective Quantum Efficiency DQE has been calculated from these parameters. In particular the low spatial frequency aspects of the noise power spectrum and of the DQE, which are the ones most relevant in medical X-ray diagnosis, will be considered in more detail.
