Digital image receptors are more sensitive to which factor?

• A. Scatter and background radiation
• B. Fluorescent lights
• C. Free electrons
• D. Free radicals

Answer: (A)

Digital image receptors convert incoming x-ray photons into an electrical signal, so they are most sensitive to factors that influence the signal-to-noise ratio. Scatter and background radiation add photons that don’t carry useful image information, increasing noise and reducing image contrast. This degrades image quality even though the detector can handle a wide range of exposures. Fluorescent lights don’t contribute to the x-ray signal reaching the detector, so they don’t affect receptor sensitivity in radiography. Free electrons and free radicals are byproducts of ionization processes, not the main factors that determine how the detector responds to the x-ray signal.
