The image intensifier is a device crucial in the process of converting X-rays into visual images. It utilizes a combination of photoconductive materials and electronic components to enhance the brightness of the image formed by X-rays. The way this works is that when X-rays pass through a patient, they strike a phosphorescent screen, which subsequently emits visible light. This light is then intensified and converted into a usable image for further analysis or diagnosis.

Image intensifiers are particularly important in fluoroscopy, where real-time imaging is needed to observe dynamic events within the body. This technology enhances the visibility of the X-ray images significantly, making it easier for healthcare professionals to interpret the diagnostic information accurately.

While X-ray film does capture images produced by X-rays, it does not actively convert the X-rays into an image in the same way that an image intensifier does. Computer tomography and digital radiography may also relate to imaging techniques involving X-rays, but their processes are distinct and do not directly involve the conversion mechanism attributed to an image intensifier.
