Layers of PSPs
Photostimulable phosphor (PSP) Imaging plate has six main layers. These layers include the protective, phosphor, reflective, conductive, color, support, and backing layers (Radiology Key (a). The protective layer is a thin clear, thin and tough plastic protecting the phosphor layer. The phosphor layer is the active layer. It is the layer that traps electrons when the film is exposed to radiation. The layer may also contain color to absorb the stimulating light and […]
