The x-ray image intensifier converts the transmitted x rays into a brightened, visible light image. ... The electrons are accelerated and focused by a series of electrodes striking the output phosphor, which converts the accelerated electrons into light photons that may be captured by various imaging devices.

How does the image intensifier works?

An image-intensifier system works by collecting photons through an objective lens, converting them to electrons via a photocathode, increasing the electrical energy with a microchannel plate (MCP), converting the electrical energy back to light using a phosphor screen and presenting the image for viewing through an ...

What is the function of image intensifier in radiography?

The overall function of an image intensifier is to convert incident x-ray photons to light photons of sufficient intensity to provide a viewable image. This occurs in several stages. The first is conversion of X-ray photons to light photons by the input phosphor.
