Izisekelo zomshini we-granite sezilokhu zibhekwa njengezinto ezifanele zomkhiqizo we-computed tomography yezimboni ngenxa yobuningi bazo obukhulu, ukuqina, kanye nezakhiwo zemvelo zokudambisa. Kodwa-ke, njenganoma iyiphi into, i-granite ayinawo amaphutha ayo, futhi kuneziphambeko eziningana ezingavela esisekweni somshini we-granite ezingathinta kabi ukusebenza komkhiqizo we-computed tomography yezimboni.
Iphutha elilodwa elingenzeka esisekelweni somshini we-granite ukugoba. Naphezu kokuqina kwayo okungokwemvelo, i-granite isengagoba lapho ivezwa izinguquko zokushisa noma lapho ibhekene namazinga aphezulu okucindezeleka. Lokhu kungabangela ukuthi isisekelo somshini singalingani, okungaholela emaphutheni enqubo yokuskena ye-CT.
Esinye isici esingaba khona esisekelweni somshini we-granite ukuqhekeka. Nakuba i-granite iyinto eqinile engamelana nokuguguleka okukhulu, ayivikelekile ekuqhekekeni, ikakhulukazi uma icindezelwa ngokuphindaphindiwe noma amazinga aphezulu okudlidliza. Uma ingalawulwa, le mifantu ingonakalisa ubuqotho besakhiwo sesisekelo somshini futhi iholele ekulimaleni okwengeziwe.
Iphutha lesithathu elingenzeka esisekelweni somshini we-granite ukuvuleka. I-granite iyinto yemvelo, futhi ngenxa yalokho, ingaqukatha amaphakethe amancane omoya noma ezinye izinto ezingenza buthaka isakhiwo sesisekelo somshini. Lokhu kuvuleka kungenza futhi isisekelo somshini sibe sengozini enkulu yokulimala ngenxa yezici zemvelo ezifana nomswakama kanye nokushintsha kwezinga lokushisa.
Okokugcina, iphutha lesine elingenzeka esisekelweni somshini we-granite ukungalungi kobuso. Nakuba i-granite idume ngobuso bayo obubushelelezi, kusengaba khona ukungalungi okuncane noma ukungalungi okungathinta ukusebenza komkhiqizo we-computed tomography wezimboni. Lokhu kungalungi kungabangela ukuthi i-CT scan iphambukiswe noma ifiphale, okungalimaza ukunemba kwemiphumela.
Naphezu kwalezi ziphambeko, izisekelo zomshini we-granite zisalokhu ziyindlela ethandwayo yemikhiqizo ye-computed tomography yezimboni ngenxa yezakhiwo zayo zemvelo ezinhle kakhulu. Ngokuthatha izinyathelo zokunciphisa umthelela walezi ziphambeko, njengokusebenzisa i-granite esezingeni eliphezulu nokuqapha njalo isisekelo somshini ukuthola izimpawu zokuguguleka, kungenzeka ukugcina ukusebenza komkhiqizo we-computed tomography yezimboni nokuqinisekisa ukuthi uyaqhubeka nokusebenza ezingeni eliphezulu lokunemba nokunemba.
