Kwiminyaka yakutshanje, abavelisi abaninzi baye bavelisa iindidi ngeendidi zeemveliso emva kokubona ukubakho kwemarike koomatshini beX-reyi abaphathwayo besantya esiphezulu.Okwangoku, kukho imilinganiselo eyahlukeneyo yeemveliso kwimarike, kwaye ukubonakala kweemveliso kuyahluka.Abantu abaninzi bayothuka xa bejongana neentlobo ezininzi zeemveliso kunye neemveliso zoomatshini beX-reyi abaphathwayo xa bethenga.Ngenxa yokuba abazi ukuba yeyiphi imveliso ifaneleke ngakumbi kuxilongo lwangoku lwamazinyo kunye neemfuno zonyango, kwaye yeyiphi imveliso enokuvelisa imifanekiso ekumgangatho ophezulu.Enyanisweni, uninzi loomatshini beX-reyi abaphathwayo abakwiimarike kufuneka babe nako ukuhlangabezana neemfuno xa besenza umfanekiso wamazinyo angaphambili, yaye umahluko womgangatho ukumazinyo emolar.Umahluko unokubonwa ngokukodwa xa ubonisa i-molars ephezulu.Xa sikhetha iimveliso, akukhathaliseki nokuba imilo yomatshini weX-reyi ophathwayo we-X-reyi utshintsha njani, kufuneka sithelekise ezi parameters zintathu zilandelayo:
a) Ixabiso lekhilovolthi (KV) limisela ukungena kokudubula.Ubukhulu bexabiso lekhilovolti (KV), kokukhona butyebe bubunzima bomzimba obunokufotwa.Abona matshini baphathwayo beX-reyi kwimarike ngokusisiseko ngama-60KV ukuya kuma-70KV.
b) Ixabiso le-milliamp (mA) limisela ubuninzi (okanye umahluko omnyama nomhlophe) womfanekiso we-X-reyi.Ukuphakama kwexabiso langoku, ubukhulu becala elimnyama nelimhlophe lefilimu ye-X-ray, kunye nomxholo ocebileyo wefilimu ye-X-ray.Okwangoku, ixabiso langoku (mA) le-high-frequency portable oral X-ray machines e-China liphakathi kwe-1mA kunye ne-2mA.
c) Ixesha lokuvezwa (S) limisela idosi ye-X-reyi (oko kukuthi, inani lee-electron ezilawulwayo).Inani elikhulu langoku, liphezulu ixabiso le-KV, lifutshane ixesha elihambelanayo lokuvezwa, kunye nomgangatho womfanekiso ophezulu.
