Correct answer: D — Reduced radiation dose to the patient (by 50-90%)
Digital radiography (direct sensors or phosphor storage plates) requires significantly less radiation than conventional film (approximately 50-90% dose reduction depending on the system). Additional advantages include immediate image display, image enhancement capabilities (brightness, contrast, magnification), electronic storage and transmission, and elimination of chemical processing. Spatial resolution of digital sensors is generally slightly lower than D- or F-speed film, but diagnostic quality is comparable.
