YAP:Ce scintillator bụ kristal scintillation ọzọ ejiri ion cerium (Ce) mee.YAP na-anọchi anya yttrium orthoaluminate jikọtara ya na praseodymium (Pr) na cerium (Ce).YAP:Ce scintilators nwere mmepụta ọkụ dị elu yana mkpebi nwa oge, na-eme ka ha dabara maka nnwale physics ume dị elu yana ihe nyocha positron emission tomography (PET).

Na nyocha PET, a na-eji YAP:Ce scintillator mee otu ihe na LSO:Ce scintillator.YAP:Ce kristal na-amịkọrọ foton ndị rediotracer na-ebupụta, na-emepụta ìhè scintillation nke tube fotomultiplier (PMT) na-achọpụta.PMT wee gbanwee akara ngosi scintillation ka ọ bụrụ data dijitalụ, nke a na-ahazi iji wepụta onyonyo nke nkesa rediotracer.

YAP: A na-ahọrọ ndị scintilators Ce karịa LSO:Ce scintilators n'ihi oge nzaghachi ngwa ngwa ha, nke na-eme ka mkpebi nwa oge nke nyocha PET dị mma.Ha na-enwekwa oge ire ere dị ala, na-ebelata mmetụta nke nrụpụta na oge nwụrụ anwụ na ngwá electronic.Otú ọ dị, YAP: Ce scintilators dị ọnụ ọnụ iji mepụta ma dị obere karịa LSO: Ce scintilators, nke na-emetụta mkpebi oghere nke PET scanners.

YAP:Ce scintilators nwere otutu ngwa ma e wezụga ojiji ha na nyocha PET na nnwale physics dị elu.Ụfọdụ n'ime ngwa ndị a gụnyere:

1. Nchọpụta Gamma-ray: YAP:Ce scintilators nwere ike ịchọpụta ụzarị gamma sitere n'ebe dị iche iche, gụnyere igwe ọkụ nuklia, radioisotopes, na akụrụngwa ahụike.

2. Nleba anya radieshon: YAP:Ce scintilators nwere ike iji nyochaa ọkwa radieshon na ụlọ ọrụ ike nuklia ma ọ bụ mpaghara ihe mberede nuklia metụtara.

3. Ọgwụ nuklia: YAP:Ce scintilators nwere ike iji dị ka ihe nchọpụta na ụzọ imaging dị ka SPECT (Single Photon Emission Computed Tomography), nke yiri PET ma na-eji rediotracer dị iche.

4. Nyocha nchekwa: YAP:Ce scintilators nwere ike iji na nyocha X-ray maka nyocha nchekwa nke akpa, ngwugwu ma ọ bụ ndị mmadụ na ọdụ ụgbọ elu ma ọ bụ ebe nchekwa ndị ọzọ.

5. Astrophysics: YAP:Ce scintilators nwere ike iji chọpụta ụzarị gamma nke mbara igwe na-ebupụta site na isi mmalite astrophysical dị ka supernovae ma ọ bụ gamma-ray gbawara.
