Lead screens are primarily associated with film-screen radiography. In this type of radiography, lead screens are used to enhance image quality by reducing scatter radiation that reaches the film. This process improves the contrast of the radiographic image, allowing for better visualization of the details of the object being examined.

Film-screen systems utilize a combination of traditional film and luminescent screens that convert x-rays into visible light, which then exposes the film. The use of lead screens effectively absorbs unwanted scatter radiation that could obscure the image, thus providing a clearer and more precise radiographic outcome.

High-voltage radiography, while it involves higher energy sources that can produce x-rays, does not typically incorporate lead screens in the same manner as film-screen processes do. Instead, it relies on different methodologies and equipment tailored to handle high-energy interactions and resultant imaging.

Understanding the specific roles of lead screens within the realm of film-screen radiography is crucial for appreciating how they contribute to effective imaging techniques in this particular field.
