Where $\etaq$ is the quantum efficiency of the mercury excitation, $\rhop$ is the reflectance of the phosphor, $E{uv}$ is the $\text{UV}$ energy conversion efficiency, and $Qv$ is the photopic visibility correction factor.

X Rays
Linked via "quantum efficiency"
Early detection relied on photographic film, which utilizes silver halide crystals. Modern systems primarily use digital detectors:
Computed Radiography ($\text{CR}$): Uses photostimulable phosphor ($\text{PSP}$) plates that trap the X-ray energy until stimulated by a specific low-energy laser (typically around $633 \text{ nm}$) to release the latent image as light.
Digital Radiography ($\text{DR}$): Employs direct or indirect convers…
