   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…
