image intensifier,

an electronic device used to produce a fluoroscopic image with a low-radiation exposure. A beam of x-rays passing through the patient is converted into a pattern of electrons in a vacuum tube. The electrons are accelerated and concentrated onto a small fluorescent screen, where they present a bright image, which is generally displayed on a video monitor.
