Study Notes

  • Photostimulable phosphors are used to enhance the intensity of stimulated light.
  • Some photostimulable phosphors are fashioned similar to a radiographic intensifying screen, which is called a storage phosphor screen.
  • PSPs scatter light excessively, which makes them appear white.
  • PSPs are mechanically stable, electrostatically protected, and are positioned throughout a binder to optimize the intensity of stimulated light.
  • Some SPSs incorporate phosphors grown as linear filaments, which enhances the absorption of x-rays and limits the spread of stimulated emission.
