Crystallation Crystal
(Sub Surface Laser Gushushanya)
Ibikoresho bya Scintillation, ukoresheje pigiseli ya inorganic kristal scintillators, niikoreshwa cyane mubice no kumenya imirasire, harimo muripositron yoherejwe na tomografiya (PET) scaneri.
Mugushyiramo urumuri-ruyobora ibintu kuri kristu, imiterere yumwanya wa detectorIrashobora kunozwa kugeza kuri milimetero, ikazamura imiterere rusange ya tomografi.
Nyamara, uburyo gakondo bwaKugaragarakristu ni ainzira igoye, ihenze, kandi ikora cyane. Ikigeretse kuri ibyo, igice cyo gupakira hamwe na sensitivite ya detectorirashobora guhungabanabitewe naibikoresho bitagaragaza ibikoresho byerekana.

Ubutaka bwa Laser Gushushanya kuriCrystallation Crystal
Ubundi buryo ni ugukoreshatekinike yo munsi ya laser yo gushushanya (SSLE) tekinikeya kristu.
Mugushimangira lazeri imbere muri kristu, ubushyuhe bwabyayeirashobora gukora igenzurwa rya microcrackibyoKora nk'inzego zigaragaza, kurema nezapigiseli iyoborabidakenewe gutandukana kumubiri.
1. Nta pigiseli ifatika ya kristu isabwa,kugabanya ibintu bigoye hamwe nigiciro.
2. Ibiranga optique na geometrie yuburyo bugaragaza bishobora kubakugenzurwa neza, Gushoboza igishushanyo cya pigiseli yihariye nubunini.
3. Gusoma no gushakisha ibikoreshoguma guma kimwe nkibisanzwe pigiseli ya array.
Uburyo bwo gushushanya Laser (SSLE) kuri Scintillator Crystal
Uburyo bwo gushushanya SSLE burimointambwe zikurikira:
1. Igishushanyo:
Kwigana no gushushanyaicyifuzo cya pigiseli yubatswe, harimoibipimonaibiranga optique.
2. Icyitegererezo CAD:
Kurema aicyitegererezo cya CADyo gukwirakwiza microcrack,hashingiwe ku bisubizo byo kwigananalaser yanditseho ibisobanuro.
3. Tangira gushushanya:
Gushushanya mubyukuri bya LYSO kristu ukoresheje sisitemu ya laser,iyobowe na moderi ya CAD.
Uburyo bwo Gutezimbere SSLE: (A) Icyitegererezo, (B) Icyitegererezo CAD, (C) Yanditseho LYSO, (D) Igishushanyo Cyumwuzure
4. Isuzuma ry'ibisubizo:
Isuzuma ryimikorere ya kristu ikoresheje aishusho yumwuzurenaGaussian ikwiyegusuzuma pigiseli ireme kandi ikemurwa.
Ubutaka bwa Laser Gushushanya BISOBANUWE muminota 2
Uwitekatekinike yo munsi ya laser yo gushushanyakuri scintillator kristal itanga auburyo bwo guhindura ibintuKuri pigiseli yibi bikoresho.
Mugutanga kugenzura neza ibiranga optique na geometrie yuburyo bugaragaza, ubu buryoifasha iterambere ryuburyo bushya bwo gushakishahamwe nayazamuye imiterere yimyanya n'imikorere, byosehanzegukenera ibintu bigoye kandi bihenze pigiseli.
