Abstract
The quantum efficiency (QE) is unsuitable to characterise the performa nce of an imaging detector. Instead, the detective quantum efficiency (DQE), which indicates how much the detection process deteriorates the signal-to-noise ratio of the input image, is a more convenient parame ter. Nevertheless QE plays a relevant role in the DQE formulation, as we have shown in the present paper, which is intended as a continuatio n and improvement of a previous paper of the same authors.
