Iyini i-granite assembly ye-Computed Tomography?

I-granite assembly ye-Computed Tomography (CT) iwumklamo okhethekile osetshenziswa emkhakheni wezokwelapha ukwenza ukuskena okunembile nokunembile komzimba womuntu. Ukuskena kwe-CT kungenye yentuthuko ebaluleke kakhulu kwezobuchwepheshe emkhakheni wezithombe zezokwelapha, njengoba kwenza odokotela bakwazi ukuhlonza izimo ezahlukene zezempilo ngokunembile. Imishini yokuskena izithombe ze-CT isebenzisa ubuchwepheshe be-X-ray ukudala isithombe somzimba se-3D, okuvumela odokotela ukuthola nokuhlonza ukukhula okungavamile, ukulimala, kanye nezifo ezingenawo umthelela omkhulu.

Ukuhlanganiswa kwe-granite kwe-CT kuqukethe izingxenye ezimbili ngokuyinhloko: i-granite gantry kanye ne-granite tabletop. I-gantry inesibopho sokugcina imishini yokuthwebula izithombe nokujikeleza isiguli ngesikhathi senqubo yokuskena. Ngokuphambene nalokho, i-tabletop isekela isisindo sesiguli futhi iqinisekisa ukuzinza nokunganyakazi ngesikhathi sokuskena. Lezi zingxenye zenziwe nge-granite esezingeni eliphezulu, eqinile, enezakhiwo ezinhle zokugwema ukuphazamiseka okubangelwa ukushintshashintsha kwemvelo, njengokushintsha kwezinga lokushisa kanye nomswakama.

I-granite gantry yakhelwe ukuhlanganisa izingxenye ezahlukene ezidingekayo ekuskeni kwe-CT, njenge-X-ray tube, i-detector array, kanye ne-collimation system. I-X-ray tube itholakala ngaphakathi kwe-gantry, lapho ikhipha khona ama-X-ray angena emzimbeni ukuze adale isithombe se-3D. I-detector array, nayo etholakala ngaphakathi kwe-gantry, ibamba ama-X-ray adlula emzimbeni bese iwathumela ohlelweni lwekhompyutha ukuze kwakhiwe kabusha isithombe. Uhlelo lwe-collimation luyindlela esetshenziswa ukunciphisa i-X-ray beam ukuze kuncishiswe inani lemisebe iziguli ezivezwa kuyo ngesikhathi sokuskena.

I-tabletop ye-granite nayo iyisici esibalulekile sohlelo lwe-CT. Ihlinzeka ngeplatifomu esekela isisindo seziguli ngesikhathi sokuskena futhi iqinisekisa ukuthi indawo ezinzile, engashukumi igcinwa phakathi nayo yonke inqubo. I-tabletop iphinde ifakwe izinsiza ezithile zokubeka, njengezintambo, ama-cushion, namadivayisi okuvimba ukunyakaza, okuqinisekisa ukuthi umzimba usesimweni esifanele sokuskena. I-tabletop kumele ibe bushelelezi, ithambe, futhi ingabi nanoma yikuphi ukuguquka noma ukuphambuka ukuze kuvinjelwe noma yiziphi izinto ezibonakalayo ezithombeni ezikhiqizwe.

Ekuphetheni, i-granite assembly ye-CT scan idlala indima ebalulekile ekunembeni nasekuqondeni kwenqubo yokuthwebula izithombe zezokwelapha. Ukusetshenziswa kwe-granite esezingeni eliphezulu emishinini yezokwelapha kuthuthukisa ukuzinza komshini, ukuzinza kokushisa, kanye nezakhiwo zokwandisa ukushisa okuphansi kwemishini, ezibalulekile ekufinyeleleni imiphumela engcono kakhulu yokuthwebula izithombe. Ngokuqonda okuthuthukisiwe kwezici zokuklama kanye nokuhlanganiswa kwentuthuko entsha ezingxenyeni, ikusasa le-CT scan libukeka likhanya futhi lingangenisi kakhulu ezigulini.
