Phosphor imaging principle
WebJul 8, 2015 · Storage phosphor principle… • The imaging plate is coated with photostimulable phosphor, also called storage phosphor • The phosphor material is generally a kind of Bariumfluorohalide • The Imaging Plate contains not only the phosphor layer, but also a protective coat, a conductive layer, support and laminate layers 13. Photostimulated luminescence (PSL) is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. X-rays may induce such an energy storage. A plate based on this mechanism is called a photostimulable phosphor (PSP) plate and is one type of X-ray detector used in projectional radiography. Creating an image requires illuminating the plate twice: the first exposure, to the radiation of interest, "writes" the image, and a …

When X-ray energy is absorbed by the phosphor, electrons associated with the europium atoms are excited and become mobile, and then a fraction of them will get trapped locally in a higher energy state.
