Indibano yegranite yeComputed Tomography (CT) luyilo olukhethekileyo olusetyenziswa kwicandelo lezonyango ukwenza iiskeni zomzimba womntu ezichanekileyo nezichanekileyo. I-CT scan yenye yezona nkqubela phambili kwezobuchwepheshe kwicandelo le-medical imaging, njengoko ivumela oogqirha ukuba baxilonge iimeko ezahlukeneyo zempilo ngokuchanekileyo. Izixhobo ze-imaging ze-CT scans zisebenzisa iteknoloji ye-X-ray ukwenza umfanekiso we-3D womzimba, ovumela oogqirha ukuba bafumane kwaye bachonge ukukhula okungaqhelekanga, ukwenzakala, kunye nezifo ezingenako ukungenelela.
Indibano yegranite ye-CT iqulathe ikakhulu iindawo ezimbini: i-granite gantry kunye ne-granite tabletop. I-gantry inoxanduva lokugcina izixhobo zokuthatha imifanekiso kunye nokujikeleza isigulane ngexesha lenkqubo yokuskena. Ngokwahlukileyo koko, i-tabletop ixhasa ubunzima besigulane kwaye iqinisekisa uzinzo kunye nokungashukumi ngexesha lokuskena. Ezi zinto zenziwe nge-granite esemgangathweni ophezulu, eqinileyo, eneempawu eziphezulu zokuthintela ukuphazamiseka okubangelwa kukutshintsha kwendalo, njengokutshintsha kobushushu kunye nokufuma.
I-granite gantry yenzelwe ukudibanisa izinto ezahlukeneyo ezifunekayo kwi-CT scan, njenge-X-ray tube, i-detector array, kunye ne-collimation system. I-X-ray tube ikwi-gantry, apho ikhupha khona ii-X-ray ezingena emzimbeni ukuze zenze umfanekiso we-3D. I-detector array, ekwakwi-gantry, ibamba ii-X-ray ezidlula emzimbeni ize izithumele kwinkqubo yekhompyutha ukuze zakhiwe ngokutsha. Inkqubo ye-collimation yindlela esetyenziselwa ukunciphisa umqadi we-X-ray ukunciphisa ubungakanani bemitha evezwa zizigulane ngexesha le-scan.
Itafile yegranite nayo iyinxalenye ebalulekileyo yenkqubo ye-CT. Ibonelela ngeqonga elixhasa ubunzima bezigulane ngexesha lokuskena kwaye liqinisekisa ukuba indawo ezinzileyo nengashukumiyo igcinwa kulo lonke inkqubo. Itafile ikwaxhotyiswe ngezinto ezithile zokuncedisa ukubeka, ezifana neentambo, imiqamelo, kunye nezixhobo zokuthintela ukuhamba, eziqinisekisa ukuba umzimba ukwindawo efanelekileyo yokuskena. Itafile yetafile kufuneka igudileyo, ithe tyaba, kwaye ingabi nakuphi na ukuguquguquka okanye ukugqwetheka ukuthintela naziphi na izinto ezikwimifanekiso eyenziweyo.
Ukuqukumbela, indibano yegranite yokuskena nge-CT idlala indima ebalulekileyo ekuchanekeni nasekuchanekeni kwenkqubo yokufota ngezonyango. Ukusetyenziswa kwegranite esemgangathweni ophezulu kwizixhobo zonyango kuphucula uzinzo loomatshini, uzinzo lobushushu, kunye neempawu zokwandiswa kobushushu obuphantsi kwezixhobo, ezibalulekileyo ekufezekiseni iziphumo zomfanekiso ezilungileyo kangangoko. Ngokuqonda okuphuculweyo kweempawu zoyilo kunye nokuhlanganiswa kwenkqubela phambili entsha kwizixhobo, ikamva le-CT scan libonakala liqaqambile kwaye lingangenisi ntsholongwane kwizigulane.
