Which term describes a radiographic image with superimposed images due to exposing a receptor twice prior to development?

• A. Double exposure
• B. Overexposure
• C. Artifact
• D. Fogging

Answer: (A)

Two images overlap on one receptor when it is exposed twice before development, so the radiograph shows superimposed anatomy from both exposures. This happens if the film or sensor isn’t advanced and a second exposure is made on the same image, leading to two sets of structures appearing together and confusing the diagnostic view. The term for this exact situation is double exposure. By contrast, overexposure makes the whole image too dark but doesn’t create overlapping images, and fogging or general artifacts describe different processing or environmental issues rather than two deliberate exposures.
