| Zusammenfassung: | Scintillators are the primary radiation sensor in many applications such as
medical diagnostics, medical radiographs, and industrial component inspection.
Some of the limitations in the properties of single-crystal scintillators are
discussed for imaging applications, and the advantages of a new class of
polycrystalline ceramic scintillators are described in detail. After the
important scintillator properties of transparency, X-ray stopping power, light
output, primary speed, luminescent afterglow, and radiation damage are
described, the processing and performance of ceramic scintillators

scintillator uses and trends are presented in light of issues related to their
uses in advanced medical and industrial X-ray detectors for CT imaging
applications. Finally, some of the challenges are given for successfully
developing a polycrystalline ceramic scintillator for use in photon-counting
applications. |
