Collimators yog cov khoom siv uas taw qhia thiab lim cov khoom siv los yog yoj nqaj. Lawv txoj kev khiav hauj lwm yog ncaj nraim, raws li qhia hauv daim duab hauv qab no.
Lub collimator yog ib qho yooj yim thiab muaj txiaj ntsig kev daws teeb meem rau kev taw qhia thiab / lossis nqaim ib qho chaw diffuse ntawm EM hluav taws xob, xws li tsim cov duab ntawm lub tshuab ntes. Txawm li cas los xij, raws li tau hais dhau los, qhov qis dua lub wavelength, lub zog siab dua, txhais tau hais tias X thiab gamma rays yog EM tsis muaj zog tshaj plaws. Qhov no ua rau muaj ntau yam teeb meem, suav nrog kev nkag mus rau hauv septal, uas tshwm sim thaum lub teeb hluav taws xob muaj zog hla lub collimator septum. Qhov no ua rau muaj teeb meem tsis raug tso rau ntawm lub ntes. Txhawm rau zam qhov teeb meem no, yuav tsum siv cov atomic naj npawb siab thiab cov ntaub ntawv ntom ntom, thiab tungsten yog ib tus neeg sib tw zoo. Txawm li cas los xij, vim tias tungsten yog cov khoom siv tawv heev, cov txheej txheem machining ib txwm nyuaj rau siv. Tungsten kuj muaj qhov kub siab tshaj plaws fusion ntawm txhua yam khoom, yog li ib feem ntawm tungsten, piv txwv li, tsis tuaj yeem cam khwb cia. Feem ntau, tungsten collimators yog tsim los ntawm cov ntawv tungsten, uas ua rau cov txheej txheem nyuaj. Tag nrho cov teeb meem no ua rau tungsten additive manufacturing ib qho kev xaiv zoo heev rau kev tsim cov collimators.
