What is the purpose of a raised button on a radiograph?

A raised button on a radiograph serves primarily to mount the film. This feature is integral for proper handling and organization of radiographs. It allows for easy identification and ensures the film can be securely placed in a viewbox or holder, facilitating its examination. Additionally, mounting aids radiology professionals in maintaining the integrity and orientation of the images for accurate interpretation and record-keeping.

While image contrast, exposure settings, and recording patient details are all vital aspects of radiography, these functions are not the main purpose of the raised button. Enhancing image contrast relates to how the radiograph is developed or manipulated digitally, but does not pertain to the structural utility of the button itself. Similarly, exposure settings are determined by the radiographic equipment and not indicated by a feature on the film. Recording patient details usually requires a separate label or information system, rather than being tied to a physical characteristic of the film.
