What is referred to as the latent image in radiography?

The latent image in radiography refers to the unseen image that exists on the imaging receptor after it has been exposed to radiation but before it is processed. This occurs when the radiation interacts with the photostimulable phosphors or the silver halide crystals in the film. The exposure causes a change in the properties of these materials, creating a pattern of stored energy that corresponds to the distribution of radiation received.

Only after the processing stage, which includes steps such as developing and fixing, does the latent image become a visible image. Thus, the term "latent" signifies that the image is not yet perceptible to the human eye until it undergoes the necessary processing steps. Understanding this concept is crucial for radiologic technologists as it underlines the importance of careful handling and processing of imaging receptors to ensure high-quality images for accurate diagnosis.
