Detective Quantum Efficiency (DQE) is an actual number represented in a percentage. Which percentage below would be considered the highest DQE?

Explanation:
DQE shows how well a detector preserves image quality for a given radiation dose; it's a percentage, and higher values mean better efficiency in converting x-ray signal into a usable image with less added noise. So, among the options, the largest percentage indicates the highest DQE. Here, 80% is the highest, meaning it would have the best detector efficiency. The other options—30%, 70%, and 50%—are all lower.
