What is the purpose of a screen in radiographic testing?

In radiographic testing, the purpose of a screen is primarily to enhance image visibility and reduce the radiation dose. Screens are typically used in conjunction with film in traditional radiography; they convert the incoming radiation into visible light, which then exposes the film. This process allows for a clearer and more defined image because the film is more sensitive to the light from the screen than to the radiation itself. Consequently, using screens can significantly lower the amount of radiation required to produce a quality image, promoting safer practices in radiographic testing.

While other options focus on different aspects of radiographic technology, they do not accurately capture the core function of a screen. Increasing detail in digital images pertains more to digital imaging techniques themselves rather than the function of screens. Similarly, while screens can contribute to faster image development through light exposure, that is not their primary purpose. Finally, the storage of images for later access is unrelated to the role of screens in the imaging process, as it deals with data management rather than image production.
