Isisekelo somshini we-granite uhlobo olukhethekile lwesisekelo olusetshenziswa emishinini ye-computed tomography yezimboni. I-computed tomography (CT) imaging iyindlela engonakalisi esetshenziselwa ukubona ngeso lengqondo isakhiwo sangaphakathi sento ngaphandle kokuyilimaza. Le mishini isetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa izithombe zezokwelapha, ucwaningo lwezinto zakudala, kanye nokuhlolwa kokulawula ikhwalithi ezindaweni zezimboni.
Isisekelo somshini we-granite siyingxenye ebalulekile yomshini we-CT, njengoba sinikeza ukuzinza nokusekela ezinye izingxenye. Isisekelo ngokuvamile senziwe nge-granite eqinile ngenxa yezakhiwo zayo ezihlukile, ezifaka ukuzinza okuphezulu, ukwanda okuphansi kokushisa, kanye nokudlidliza okuncane. Lezi zakhiwo zenza i-granite ibe yinto efanelekile yezisekelo zomshini we-CT ngoba ingagcina isimo sayo futhi isekele isisindo sezinye izingxenye ngaphandle kokugoba noma ukushintsha isimo ngenxa yezinguquko ekushiseni noma ekudlidlizeni.
Ngaphezu kokuba yinto ezinzile neqinile, i-granite nayo ayinamandla futhi ayinamandla okuhambisa izinto, okuyinto ebalulekile ekuthathweni kwezithombe ze-CT. Imishini ye-CT isebenzisa ama-X-ray ukudala izithombe zento eskeniwayo, futhi izinto ezisebenzisa amandla okuhambisa izinto zingaphazamisa ikhwalithi yezithombe. Ukusetshenziswa kwezinto ezisebenzisa amandla okuhambisa izinto ezinganamandla okuhambisa izinto njenge-granite kusiza ukuqinisekisa ukuthi izithombe ezikhiqizwa umshini we-CT zinembile futhi zithembekile.
Izisekelo zomshini we-granite zivame ukwenziwa ngokwezifiso ukuze zivumelane nobukhulu obuthile bomshini we-CT. Inqubo yokugaya esetshenziswa ukudala isisekelo ihilela ukusika nokupholisha i-granite slab ukuze kudalwe indawo ebushelelezi neqondile. Isisekelo sibe sesifakwa ochungechungeni lwama-vibration-dampening pads ukuze kuncishiswe noma yikuphi ukudlidliza okungase kuphazamise ikhwalithi yezithombe ze-CT.
Sekukonke, isisekelo somshini we-granite siyingxenye ebalulekile yomshini we-CT wezimboni, ohlinzeka ngokuqina, ukunemba, kanye nokusekelwa kwezinye izingxenye. Izakhiwo zayo ezihlukile zenza kube yinto efanelekile yalolu hlelo lokusebenza, futhi ukusetshenziswa kwayo kusiza ukuqinisekisa ukunemba nokuthembeka kwezithombe ezikhiqizwe umshini we-CT. Njengoba ubuchwepheshe buthuthuka kanye nokuthwebula izithombe ze-CT kuqhubeka nokusetshenziswa ezinhlobonhlobo zezicelo, ukubaluleka kwesisekelo somshini esizinzile nesithembekile kuzoqhubeka nokukhula.
