| Abstract: | The mechanism of X-ray intensifying screen,X-ray computed tomography(X-CT),and Positron
Emission Tomography (PET) as well as their demand for inorganic scintillators are introduced in this paper.A few of the most promising inorganic scintillators,such as cerium doped Lutetium oxyorthosihcate (LSO:Ce),Lutetmm Aluminum Perovskite (LuAP:Ce) and lead tungstate.as well as their limitations are presented.It is also pointed out that the fast-rising transparent scintillation ceramics are becoming strong competitors with traditional scintillation crystals. |
