Uyini umhlangano we-granite we-Computed Tomography?

I-granite assembly for Computed Tomography (CT) iwumklamo okhethekile osetshenziswa emkhakheni wezokwelapha ukwenza izikena ezinembe kakhulu nezinembayo zomzimba womuntu.I-CT scanning ingenye yentuthuko yezobuchwepheshe ebaluleke kakhulu emkhakheni we-imaging yezokwelapha, njengoba yenza odokotela bakwazi ukuxilonga izimo zempilo ezihlukahlukene ngokunembile.Imishini yokuthwebula ye-CT scan isebenzisa ubuchwepheshe be-X-ray ukuze yenze isithombe somzimba se-3D, esivumela odokotela ukuthi bathole futhi bahlonze ukukhula okungavamile, ukulimala, nezifo ezihlasela kancane.

I-granite assembly ye-CT iqukethe ngokuyinhloko izingxenye ezimbili: i-granite gantry kanye ne-tabletop ye-granite.I-gantry inomthwalo wemfanelo wokuhlalisa okokusebenza kwezithombe nokuzungeza isiguli ngesikhathi senqubo yokuskena.Ngokuphambene, i-tabletop isekela isisindo sesiguli futhi iqinisekisa ukuzinza nokungakwazi ukuhamba ngesikhathi sokuskena.Lezi zingxenye zenziwe nge-granite yekhwalithi ephezulu, ehlala isikhathi eside, enezakhiwo eziphakeme ukugwema ukuhlanekezela okubangelwa ukuhlukahluka kwemvelo, njengokushintsha kwezinga lokushisa nomswakama.

I-granite gantry yakhelwe ukuhlanganisa izingxenye ezihlukene ezidingekayo ukuze kuthwetshulwe i-CT, njengeshubhu le-X-ray, i-detector array, kanye nesistimu yokushayisana.Ishubhu le-X-ray lingaphakathi kwe-gantry, lapho likhipha khona ama-X ray angena emzimbeni ukuze enze isithombe se-3D.I-detector array, nayo etholakala ngaphakathi kwe-gantry, ithwebula ama-X-ray adlula emzimbeni bese iwadlulisela ohlelweni lwekhompyutha ukuze kwakhiwe kabusha isithombe.Uhlelo lwe-collimation luwumshini osetshenziselwa ukunciphisa i-X-ray ukuze kwehliswe inani lemisebe iziguli ezichayeka kuyo ngesikhathi sokuskena.

I-tabletop ye-granite iyingxenye ebalulekile yesistimu ye-CT futhi.Ihlinzeka ngenkundla esekela isisindo seziguli ngesikhathi sokuskena futhi iqinisekise ukuthi indawo ezinzile, enganyakazi iyagcinwa phakathi nayo yonke inqubo.Ithebulethi ibuye ifakwe izinsiza eziqondile zokubeka indawo, njengezintambo, amacushion, nezinto ezivimbela ukuhamba, eziqinisekisa ukuthi umzimba usesimweni esifanele sokuskena.Ithebulethi kufanele ibe bushelelezi, ibe sicaba, futhi ingaguquki noma ihlanekezelwe ukuze kuvinjelwe noma yimaphi ama-artifact ezithombeni ezikhiqiziwe.

Sengiphetha, umhlangano we-granite wokuskena kwe-CT udlala indima ebalulekile ekunembeni nasekunembeni kwenqubo yezithombe zezokwelapha.Ukusetshenziswa kwe-granite yekhwalithi ephezulu emishini yezokwelapha kuthuthukisa ukuzinza kwemishini, ukuzinza kokushisa, kanye nezakhiwo eziphansi zokunweba ezishisayo zemishini, okubalulekile ekuzuzeni imiphumela engcono kakhulu yokucabanga ngangokunokwenzeka.Ngokuqonda okuthuthukisiwe kwezici zokuklama kanye nokuhlanganiswa kwentuthuko entsha ezingxenyeni, ikusasa lokuskena kwe-CT libukeka likhanya futhi lingangeni ezigulini.
