Scintillation Crystal
(Sub Surface Laser Graving)
Baaraha ku salaysan scintillation, iyadoo la isticmaalayo scintilators crystal inorganic pixelated, waasi weyn loogu isticmaalo ogaanshaha walxaha iyo shucaaca, oo ay ku jiraanSawir-qaadayaasha positron emission tomography (PET)..
Adigoo ku daraya sifooyin hagaya muraayadda, xallinta meel bannaan ee baarahawaxaa lagu hagaajin karaa miisaanka millimitirka, iyadoo kor loo qaadayo xallinta guud ee sawir-gacmeedka.
Si kastaba ha ahaatee, habka dhaqanka eemuuqaal ahaan pixelatingcrystals waa aqallafsan, qaali, iyo geeddi-socod shaqo badan. Intaa waxaa dheer, jajabka xirxiran iyo dareenka baarahawax loo dhimi karosababo la xiriiraagabka milicsiga ee la isticmaalo.

Natiijooyinka SSLE Scintillation Crystal
1. Wax-soosaarka Iftiinka oo la hagaajiyay
Bidix: Dul-xun oo ku xardhan Asymmetry DoI Dulmarka.
Midig: Barakaca Pixel DoI.
Isbarbardhigga garaaca wadnaha u dhexeeyalaysarka dhulka hoostiisa ku xardhan (SSLE)iyohabaynta caadiga ahmuujinaysaa aWax-soosaarka iftiinka aad uga fiican SSLE.
Tani waxay u badan tahay inay sabab u tahaymaqnaanshaha muraayadaha caagga ahinta u dhaxaysa pixels-yada, taas oo keeni karta is-maandhaaf xagga indhaha ah iyo luminta sawir-qaadista.
Dhalidda iftiinka ee la hagaajiyay macnaheedu waaIftiin badan oo isku mid ah garaaca tamarta, samaynta SSLE sifo la rabo.
2. Habdhaqanka wakhtiga oo la wanaajiyey
Sawirka Scintillation Crystal
Dhererka Crystal wuxuu leeyahay asaameyn xun ku leh waqtiga, kaas oo muhiim u ah codsiyada Positron Emission Tomography (PET).
Si kastaba ha ahaatee, thedareenka sare ee crystals SSLEogolaanaya isticmaalkacrystals gaaban, kaas oo karahagaajin habdhaqanka wakhtiga ee nidaamka.
Jilidyadu waxay sidoo kale soo jeediyeen in qaababka pixel ee kala duwan, sida laba geesoodka ama dodecagonal, laga yaabou horseedo hagitaan-iftiin wanaagsan iyo waxqabad waqtiyeed, oo la mid ah mabaadi'da fiilooyinka indhaha.
3. Faa'iidooyinka Qiimaha leh
Sawirka Scintillator Crystal
Marka loo eego blocks monolithic, qiimaha kiristaalo SSLEwuxuu noqon karaa mid hooseeya sidasaddex meelood meelee kharashkaee shaxanka u dhigma ee pixelated, taas oo ku xidhan cabbirka pixel.
Intaa waxaa dheer, eedareenka sare ee crystals SSLEogol yahayisticmaalka kiristaalo gaaban, hoos u dhigista qiimaha guud.
Farsamada SSLE waxay u baahan tahay awoodda leysarka hoose marka loo eego goynta laysarka, taas oo u oggolaanaysaNidaamyada SSLE ka jabanmarka la barbardhigo laysarka dhalaalay ama goynta.
