What is a latent image?

• A. Latent Image
• B. Intraoral Film
• C. Occlusal
• D. Panoramic Film

Answer: (A)

The latent image is the invisible picture formed on the film right after exposure to x-rays, before any development. When x-rays hit the film’s silver halide crystals, they create a chemical change in those crystals that encodes the pattern of the anatomy being imaged, but this pattern isn’t visible yet. It remains hidden until the film is developed, at which point the exposed crystals are converted into metallic silver and the image becomes visible. The other terms describe the film or the type of radiographic view, not the image itself.
