High DQE radiographs exhibit which combination of signal and noise?

Explanation:
High DQE means the detector is very efficient at turning incoming x-rays into useful image signal while keeping noise low. This produces a radiograph with a strong signal and minimal random fluctuations, i.e., a high signal with low noise. In practice, better detective quantum efficiency improves image quality without needing more dose, so the image remains sharp and clean. Low signal or high noise would degrade detail, while high signal with high noise isn’t desirable.
