Emkhakheni wokukhiqiza imishini yezokwelapha, ukunemba kokucubungula kwezingxenye zemishini ye-radiotherapy enembile kakhulu kuhlobene ngqo nokusebenza kwemishini kanye nomphumela wokwelashwa kweziguli. Ipulatifomu yokunyakaza kwe-gantry enembile ye-XYZT incike ezinzuzweni ezihlukile zezingxenye ze-granite, ihlinzeka ngesiqinisekiso esiqinile sokusika okunembile, ukubhoboza kanye neminye imisebenzi ye-simulators yezicubu zomuntu.
Ukuqina okuhle kakhulu kuqinisekisa indawo eqondile
Ukucutshungulwa kwezingxenye zemishini yokwelapha ngemisebe kudinga ukunemba okuphezulu kakhulu kokuma, futhi noma yikuphi ukuphambuka okuncane kungathinta ukukhanyiswa okunembile kwezicubu zesimila ngesikhathi sokwelashwa ngemisebe. Izingxenye zegranite zesikhulumi se-XYZT ngokunemba kokunyakaza kwe-gantry, isakhiwo sangaphakathi siminyene futhi siyafana, sinokuqina okuhle kakhulu. Ubuningi bayo bufinyelela ku-2.6-2.7g/cm³, okungamelana ngempumelelo nokuphazamiseka kokudlidliza kwangaphandle, ngisho nasendaweni eyinkimbinkimbi ye-workshop, kodwa futhi kunciphise ubukhulu bokudlidliza kwepulatifomu ngaphezu kuka-80%. Lapho usika futhi ubhoboza ama-simulants ezicubu zabantu, izingxenye zegranite zinikeza ukwesekwa okuqinile kwepulatifomu ukuqinisekisa ukubeka kahle ithuluzi noma ithuluzi lokusika, ngokunemba kokuma kufika ku-±0.01mm. Isibonelo, lapho kucutshungulwa amaqabunga e-collimator emishini yokwelapha ngemisebe, isikhundla nesimo samaqabunga kungalawulwa ngokunembile, ukuze imisebe igxile ngokunembile endaweni yesimila, kugwenywe ukulimala kwezicubu ezinempilo ezizungezile.
Ukuqina okuphezulu ukuhlangabezana nezidingo zomshini wokulungisa ngokunemba okuphezulu
Inqubo yokusika nokubhoboza ama-simulant ezicubu zabantu inezidingo eziqinile zokuqina kwemishini. Izingxenye ze-granite ziqinile kakhulu futhi zinamandla okucindezela afinyelela ku-200-300MPa, ezingamelana namandla amakhulu okusika asetshenziswa yithuluzi enqubweni yokucubungula ngaphandle kokuguquka okusobala. Ngesikhathi sokubhoboza kwe-simulation, ipulatifomu ingahlala izinzile ukuvimbela ukufuduka kwendawo yokubhoboza noma ukuphambuka komgodi ngenxa yamandla. Endabeni yezingxenye zombhede wokwelapha wokwenziwa kwemishini ye-radiotherapy, ukubhoboza okunembe kakhulu kuyadingeka ezintweni ezilingisa isakhiwo samathambo omuntu ukuze kufakwe izinto ezidingekayo. Izingxenye ze-granite zepulatifomu yokunyakaza kwe-gantry eqondile ye-XYZT zisekela ukusebenza okuzinzile kwepulatifomu, futhi iphutha lokunemba kwendawo yembobo ebhoboziwe lilawulwa ngaphakathi kwe-±0.02mm, ukuqinisekisa ukuthi umbhede wokwelapha ungalungisa ngokunembile indawo yesiguli ngesikhathi sokusetshenziswa, futhi uhlangabezane nezidingo zemishini ye-radiotherapy yokubeka ngokunembe kakhulu.
Ukuqina kokushisa kugcina ukunemba komshini okuqhubekayo
Enkambisweni yokucubungula izingxenye zemishini yezokwelapha, ukusika ukushisa, izinguquko zokushisa kwemvelo kanye nezinye izici kuzothinta ukunemba kokucubungula. I-coefficient yokukhulisa ukushisa kwe-granite iphansi kakhulu, ngokuvamile ku-5-7 × 10⁻⁶/℃, futhi usayizi ushintsha kancane kakhulu lapho izinga lokushisa lishintshashintsha. Lapho kucutshungulwa izifanisi zezicubu zabantu isikhathi eside, noma ngabe izinga lokushisa le-workshop lishintshashintsha ku-5-10 ° C ngenxa yokusebenza kwemishini, umoya opholile nezinye izizathu, ipulatifomu esekelwa yizingxenye ze-granite isengakwazi ukugcina usayizi ozinzile ukuqinisekisa ukuthi ukunemba kokusika nokubhoboza akuthinteki. Isibonelo, ekusikeni ngokunembile kwezinto ezilingisa izicubu ezithambile zabantu, ukuthamba kanye nokuphela kwendawo yokusika kungaqinisekiswa ukuze kuhlangatshezwane nezidingo zokuzivumelanisa kahle nezingxenye zemishini ye-radiotherapy kanye nezicubu zabantu, futhi kuthuthukiswe ukuphepha nokusebenza kahle kwemishini ye-radiotherapy.
