X-ray image intensifier

X-ray image intensifier is an imaging component which converts x-rays into a visible image. The term image intensifier refers to a specific component of an x-ray imaging system, which allows low intensity x-rays to be converted to a visible light output. The device contains a low absorbency/scatter input window, typically aluminum, input fluorescent screen, photocathode, electron optics, output fluorescent screen and output window. These parts are all mounted in a high vacuum environment within glass or more recently, metal/ceramic. It allows the viewer to more easily see the structure of the object being imaged than past fluorescent screens. The X-ray II requires lower dose rates due to more efficient conversion of x-ray quanta to visible light. The input screens range from 15–57 cm, with the 23 cm, 33 cm and 40 cm being among the most common. Within each image intensifier, the actual field size can be changed using the voltages applied to the internal electron optics to achieve magnification and reduced viewing size. Modern imaging systems will use the image intensifier as the source of images supplied to a storage system.
