produkt Omskriuwing
GOS: Pr / GOS: Tb is in keramysk materiaal gearstald út gadolinium oxysulfide aktivearre troch praseodymium (Pr) of terbium (Tb) as doping eleminten.Mei poerbêste scintillaasje-eigenskippen wurdt it in protte brûkt as scintillatormateriaal yn medyske ôfbyldingsapparatuer lykas PET-scanners.It scintillaasjeproses omfettet it konvertearjen fan hege-enerzjyfotonen, of dieltsjes, yn sichtber ljocht.
As opwekke troch ynfallende strieling, emitearje gadoliniumatomen yn GOS: Pr / GOS: Tb fotonen, dy't dan wurde ûntdutsen troch fotodetektors.Dit proses lit sekuere ôfbylding en deteksje fan stralingsboarnen mooglik meitsje.GOS: Pr / GOS: Tb binne bekend om har hege ljochtútfier, koarte ferfaltiid en lege neigloeden, wêrtroch rappe en krekte stralingsdeteksje mooglik is.It hat ek hege stopkrêft tsjin röntgenstralen en gammastrielen, wêrtroch it heul effektyf is yn medyske ôfbyldingsapplikaasjes.Oer it algemien is de GOS: Pr / GOS: Tb keramyk in weardefol scintillatormateriaal dat it fjild fan medyske ôfbylding revolúsjonearre hat, wat liedt ta eardere diagnoaze en effektiver behanneling fan sykten.
