What is the primary purpose of an image intensifier?

The primary purpose of an image intensifier is to enhance image brightness. Image intensifiers are crucial components in fluoroscopy systems. They work by converting the incoming x-ray photons, which produce a very low-level visible light image, into a brighter image that can be easily viewed and analyzed. This process significantly improves the visibility of structures within the body, allowing for clearer real-time imaging during procedures.

This enhancement not only aids in diagnosis and treatment but also allows clinicians to work more effectively by reducing the need for higher radiation doses. By amplifying the light image produced by the x-ray exposure, the image intensifier enables high-contrast visuals without excessively increasing the amount of radiation used. This ultimately helps maintain patient safety and improves the overall quality of the imaging process.
