Scintillation Crystal
(Sub Surface Laser Engraving)
Scintillation-based detectors, siv pixelated inorganic crystal scintillators, yogdav siv rau particle thiab hluav taws xob kuaj pom, suav nrog hauvPositron emission tomography (PET) scanners.
Los ntawm kev ntxiv cov teeb pom kev zoo rau cov siv lead ua, qhov kev daws teeb meem ntawm lub teeb pom kev zootuaj yeem txhim kho mus rau qhov ntsuas millimeter, txhim kho tag nrho cov kev daws teeb meem ntawm tomograph.
Txawm li cas los xij, txoj kev cai ntawmlub cev pixelatingcov crystals yog ibcomplex, kim, thiab laborious txheej txheem. Tsis tas li ntawd, qhov packing feem thiab rhiab heev ntawm tus ntestuaj yeem cuam tshuamvim ocov khoom siv tsis-scintilating reflective.
