In radiological modalities, the DQE describes how effectively an x-ray imaging system can produce an image in terms of the signal-to-noise ratio (SNR) relative to an ideal detector for a full range of detail sizes. <br /> <br /> '''Return to [[ICRP Glossary|Glossary]]'''<br /> <br /> == Previous glossary entries ==<br /> <br /> === from [[ICRP Publication 129]], 2015 ===<br /> <br /> A widely used metric that describes the quality of an x-ray detector. It measures the efficiency (i.e. signal-to-noise performance) of the detector to produce an image from a given incident fluence. Intuitively it captures how well a detector translates the fluence incident on it into an image relative to an ideal detector.</div>
