What is the primary purpose of an image intensifier in radiology?

The primary purpose of an image intensifier in radiology is to intercept x-ray photons and convert them into visible light. This technology enhances the visibility of the image produced from x-rays, allowing for better observation and interpretation of the areas being examined. The image intensifier increases the luminance of the image, enabling radiologists to view high-resolution images in real-time while reducing the required amount of radiation exposure to the patient. This process is integral to fluoroscopy, where continuous imaging is necessary, such as during interventional procedures.

By converting x-ray photons to visible light, the image intensifier not only improves the clarity of the images but also facilitates quicker and more effective diagnostics and interventions. Understanding this role is essential for comprehending the advancements in imaging technology and their applications in clinical practices.
