An X-ray image intensifier (XRII) refers to a special image intensifier device used in medical imaging involving x rays. It consists of an input window, input phosphor, photocathode, vacuum and electron optics, output phosphor and output window. It allows for lower x-ray doses to be used on patients by magnifying the intensity produced in the output image, enabling the viewer to easily see the structure of the object being imaged.
