Detective Quantum Efficiency (DQE) - Video Lesson

Hey, everybody. Welcome back. This lesson is about detective quantum efficiency. Commonly abbreviated DQE. Technically speaking, detective quantum efficiency is the ratio of squared output signal to noise ratio to the squared input to signal ratio of the imaging detector. Does that make sense? No. So here's a different definition that's a little easier to understand. Detective quantum efficiency or DQE is a score that describes the ability of the imaging system to convert the remnant X-ray beam into a high quality image. The name itself tells us what it means. It's the efficiency or ability of the imaging system to detect and convert quantum into an image. Quantum is a word for photons. So here's why that matters. A high DQE is good. This means the system has high efficient
