Overview of intensifying screen

According to the use, the sensitizing screen can be divided into medical, dental and industrial uses. Lead foil and stainless steel are mainly used in industry for industrial nondestructive testing.

Medical intensifying screen is an indispensable and important equipment for clinical X-ray photography. When used in combination with X-ray film, X-rays penetrating human body can be converted into visible light to make the film sensitive, thus improving the utilization efficiency of X-rays to make the film sensitive. It has been determined that more than 95% of the optical density images formed on the X-ray film are caused by the fluorescent substances on the intensifying screen converting X-ray energy into visible fluorescent energy and then exposing the film, while less than 5% of the optical density images are formed by the direct exposure of X-rays. Therefore, the use of intensifying screen not only greatly reduces the radiation damage of X-rays, but also further expands the inspection means and application scope of X-ray photography.
