Deskrizzjoni tal-prodott
GOS:Pr/GOS:Tb huwa materjal taċ-ċeramika magħmul minn gadolinium oxysulfide attivat minn praseodymium (Pr) jew terbium (Tb) bħala elementi tad-doping.Bi proprjetajiet ta 'tpetpett eċċellenti, huwa użat ħafna bħala materjal ta' tpetpet f'tagħmir ta 'l-immaġini mediċi bħal skaners tal-PET.Il-proċess ta 'tpetpet jinvolvi l-konverżjoni ta' fotoni ta 'enerġija għolja, jew partiċelli, f'dawl viżibbli.
Meta eċċitati minn radjazzjoni inċidentali, l-atomi tal-gadolinju f'GOS:Pr/GOS:Tb jarmu fotoni, li mbagħad jiġu skoperti minn photodetectors.Dan il-proċess jippermetti immaġni preċiżi u skoperta ta 'sorsi ta' radjazzjoni.GOS:Pr/GOS:Tb huma magħrufa għall-output tad-dawl għoli tagħhom, ħin qasir ta 'tħassir u afterglow baxx, li jippermettu skoperta ta' radjazzjoni veloċi u preċiża.Għandu wkoll qawwa għolja ta 'waqfien kontra r-raġġi X u r-raġġi gamma, li jagħmilha effettiva ħafna fl-applikazzjonijiet tal-immaġini mediċi.B'mod ġenerali, iċ-ċeramika GOS:Pr/GOS:Tb hija materjal ta 'xpetpett ta' valur li rrivoluzzjona l-qasam tal-immaġini mediċi, li wassal għal dijanjosi aktar bikrija u trattament aktar effettiv tal-mard.
