Iziseko zegranite zizinto ezibalulekileyo kwiisistim ze-computed tomography zemizi-mveliso, njengoko zibonelela ngomphezulu ozinzile kunye nothe tyaba kwisixhobo seX-reyi yesistim kunye nesampulu eskeniweyo.Ukudityaniswa, ukuvavanywa, kunye nokulinganisa isiseko segranite kufuna inkqubo ecokisekileyo necokisekileyo yokuqinisekisa iziphumo ezichanekileyo nezithembekileyo.
Nantsi imiyalelo yesinyathelo-nge-nyathelo malunga nendlela yokudibanisa, ukuvavanya, kunye nokulinganisa isiseko segranite kwiimveliso ze-tomography zekhompyutha.
Ukudibanisa isiseko seGranite:
1. Khupha isiseko segranite kwaye usihlole ukuba akukho monakalo okanye iziphene.Ukuba ufumana nayiphi na imiba, qhagamshelana nomvelisi okanye umboneleli ngoko nangoko.
2. Faka iinyawo zokulinganisa ukuqinisekisa ukuba isiseko segranite sizinzile kwaye sithe tyaba.
3. Beka i-X-ray detector mount phezu kwesiseko segranite, uyikhusele ngezikrufu.
4. Faka isibambi sesampula, uqinisekise ukuba siphakathi kwaye sikhuselekile.
5. Fakela naziphi na izincedisi ezongezelelweyo okanye amacandelo, njengezinto ezikhuselayo, ukugqibezela indibano.
Ukuvavanya isiseko seGranite:
1. Yenza uhlolo olubonakalayo lwesiseko segranite kunye nawo onke amacandelo ukuqinisekisa ukuba afakwe ngokufanelekileyo kwaye alungelelaniswe.
2. Sebenzisa inqanaba elichanekileyo ukujonga ukuthambeka komhlaba wegraniti.Umphezulu kufuneka ube kwinqanaba ukuya ngaphakathi kwe-0.003 intshi.
3. Yenza uvavanyo lwe-vibration kwisiseko segranite ukuqinisekisa ukuba izinzile kwaye azikho nakuphi na ukungcangcazela okunokuchaphazela ukuchaneka kwe-CT scan.
4. Qwalasela ucoceko olujikeleze isibambi sesampulu kunye ne-X-ray detector detector ukuqinisekisa ukuba kukho indawo eyaneleyo yesampuli ukuba iskeniwe kwaye akukho kuphazamiseka kuyo nayiphi na into.
Ukulinganisa isiseko seGranite:
1. Sebenzisa isampuli yereferensi yemilinganiselo eyaziwayo kunye noxinaniso ukulinganisa inkqubo ye-CT.Isampulu yesalathiso kufuneka yenziwe ngento efana naleyo ihlalutywayo.
2. Skena isampula yereferensi kunye nesistim ye-CT kwaye uhlalutye idatha ukumisela i-CT number calibration factor.
3. Faka i-CT number calibration factor to CT data efunyenwe kwezinye iisampuli ukuqinisekisa iziphumo ezichanekileyo nezithembekileyo.
4. Yenza qho iitshekhi zokulinganisa iinombolo ze-CT ukuqinisekisa ukuba isistim ifakwe imilinganiselo kwaye isebenza ngokuchanekileyo.
Ukuqukumbela, indibano, ukuvavanywa, kunye nokulinganisa isiseko segranite yeemveliso zetomography ekhompyutheni yeshishini zifuna ingqalelo enononophelo kwiinkcukacha kunye nokuchaneka.Landela la manyathelo angasentla ukuqinisekisa iziphumo ezichanekileyo nezithembekileyo.Khumbula ukujonga rhoqo kwaye ugcine isistim ukuqinisekisa ukusebenza kakuhle.
