Fluoroscopy Image Intensifiers - Video Lesson

In this session, we're gonna take a closer look at the operation of the image intensifier. As we said, the image intensifier is a key component in the fluoroscopic imaging chain. The image intensifier is a tube with a vacuum. It can be a glass envelope tube or a metal envelope tube. But the intent of the intensifier is essentially to convert energy from one type to another. So for all practical purposes, it is an energy conversion tube. So how does it operate? We basically take the invisible energy of X-ray directed towards an input phosphor of cesium iodide. Convert that invisible energy of x-ray to visible light. That light energy is then directed directly at a photocathode assembly. The
