Image intensifier tubes (IITs) are optoelectronic devices that allow many devices, such as night vision devices and medical imaging devices, to function. They convert low levels of light from various wavelengths into visible quantities of light at a single wavelength.

Intensifying screens are used in the x-ray cassette to intensify the effect of the x-ray photon by producing a larger number of light photons. It decreases the mAs required to produce a particular density and hence decreases the patient dose significantly.
Feb 27, 2016 · The image intensifier is situated within the fluoroscopic tower and is attached to a camera tube. The method of attachment depends on the image-capture features of the system. The entire tube is approximately 50 cm in length and 15 to 58 cm in diameter (diameter depends on manufacturer and intended use).
Usually the following parameters are used to describe the image intensifier tube performance: • the signal to noise ratio (SNR) • the limiting resolution (lp/mm)

The X-ray image intensifier is a vacuum tube that converts the X-ray image into a visible light image that is brighter than that achievable by a simple fluorescent screen. Figure 8 is a schematic sagittal section of a single-mode X-ray image intensifier.
In this article, we cover in some detail how an ICCD camera works and how specific image intensifiers operate. We look at gating, dynamic range and fast phosphor and finally resolution. Intensified CCDs can use the inherent signal gain to overcome the read noise limit.
