WebIn photostimulable storage phosphor (CR) systems, x-ray photons are absorbed in the storage phosphor, also known as the imaging plate (IP). Unlike conventional screens, the deposition of x-ray energy in storage phos-phors results in the storage of a portion of the energy in highly localized, metastable areas called f-centers, which WebThe phosphor layer absorbs X-ray photons and emits visible photons predominately at 545 nm (2.28 eV), and has approximately a 15% conversion efficiency, i.e. 15% of the absorbed X-ray photon energy is converted into visible photons. However, only a fraction of generated photons will reach the detector as they are emitted in all directions. WebThe characteristic X-rays created by each atom in the thin specimen were independent of each other. In addition, the secondary Xray fluorescence was - not decayed. Therefore, the characteristic X-rays created by the detector can be recorded directly with no absorption or improvement. In this case, the matrix effect does not exist. motorcycle pants perth
