Uma kukhulunywa ngokucabanga kwezokwelashwa, i-X-ray Technology iyithuluzi elikhulu elinganikeza imininingwane ebalulekile yokuxilonga. Imishini ye-X-ray iqukethe izakhi eziningana, futhi into ethile ebalulekileIgridi ye-X-ray. Igridi ye-X-ray isetshenziselwa ukuthuthukisa ikhwalithi yesithombe ngokunciphisa imisebe yokusakaza kanye nokwenza ngcono umehluko wesithombe. Ukukhetha igridi ye-x-ray efanelekile yakhoUmshini we-X-raykubalulekile ekuqinisekiseni imiphumela efanelekile futhi ecacile yokucabanga. Kulesi sihloko, sizoxoxa ngezinto okufanele sizicabangele lapho sikhetha igridi ye-X-ray ngomshini wakho we-X-ray.
Ngaphambi kokuthi siye kwinqubo yokukhetha, ake siqonde izisekelo zegridi ye-X-ray. Igridi ye-X-ray iyithuluzi elihlanganiswe nemichilo emincane eholayo eshintshana ngezinto ezibonakalayo ze-radiolucent. Umsebenzi oyinhloko wegridi ukudonsa imisebe yokusakaza ephakama lapho ama-x-ray photon ehlangana nomzimba wesiguli. Ukusakaza imisebe kunganciphisa kakhulu ikhwalithi yesithombe ngokukhiqiza isizinda esithandekayo esaziwa ngokuthi "imigqa yegridi." Ngokuthola imisebe yokusakaza, amagridi we-X-ray asiza ukuthuthukisa umehluko wesithombe, okuholela ezithombeni ezibukhali.
Isici esibaluleke kakhulu okufanele sicabange lapho ukhetha igridi ye-X-ray yisilinganiso saso. Isilinganiso segridi sibhekisela ekuphakameni kwemichilo eholayo ngokuqhathaniswa nebanga phakathi kwabo. Izilinganiso zegridi ezivame kakhulu zingu-6: 1, 8: 1, 10: 1, no 12: 1. Izilinganiso zegridi eziphakeme zinikezela ngokufakwa okungcono kwemisebe yokusakaza noma zidinga izindlela eziphakeme ze-X-ray tube. Ngokuvamile, isilinganiso esingu-10: 1 noma 12: 1 isilinganiso segridi silungele i-general radiography, njengoba isusa ngokufanele ukusakazeka kwemisebe ngaphandle kokukhulisa umthamo wesineke ngokweqile.
Enye into ebucayi imvamisa yegridi, emelela inani lemichilo yokuhola nge-intshi noma isentimitha. Ama-frequency aphezulu wegridi aphumela emichimeni emincane futhi emfishane ehola phambili, ethuthukisa ikhwalithi yesithombe kepha andise izindleko zegridi ye-x-ray. Imvamisa yegridi yemigqa eyi-103 nge-intshi noma imigqa engama-40 ngesentimitha ngalinye lisetshenziselwa kakhulu i-general radiography. Kodwa-ke, imvamisa yegridi ephakeme, enjengemigqa engu-178 nge-intshi ngayinye noma imigqa engama-70 ngephesenti ngalinye, inconyelwe izinhlelo zokusebenza ezikhethekile zemicabango ezidinga ikhwalithi ephezulu yesithombe edinga.
Ngaphezu kwesilinganiso segridi kanye nemvamisa, impahla yegridi nayo ibalulekile. Izinto ezahlukahlukene, njenge-aluminium, i-carbon fiber, kanye namagridi e-hybrid, asetshenziswa ekwenzeni ama-x-ray grids. Ama-aluminium grids asetshenziswa kakhulu ngenxa yokusebenza kwezindleko zawo kanye namakhono amahle wokumunca. Kodwa-ke, bavame ukuba nzima futhi kungadala ukucekelwa phansi kwesithombe uma kungahambelani kahle nobango we-x-ray. Amagridi e-Carbon fiber angasindi futhi anikela ngezakhiwo ezinhle kakhulu zokumuncwa, kepha zibiza kakhulu. Amagridi e-Hybrid ahlanganisa izinzuzo ze-aluminium ne-carbon fiber grids, enikeza ukulinganisela okuhle phakathi kwezindleko nokusebenza.
Kubalulekile futhi ukuthi ucubungule ububanzi obugxile begridi, obubhekisela ebangeni lamabanga ama-X-ray tube-to-grid lapho igridi isebenza kahle khona. Imishini ehlukene ye-X-ray inezidingo ezahlukahlukene zohlobo olugxile, kanye nokukhetha igridi ehambelana nemininingwane yomshini wakho ibalulekile. Kusetshenziswa igridi ngaphandle kwebanga lokugxila elinconyiwe kungaholela kwikhwalithi yesithombe se-suffTimal kanye ne-dose yesiguli eyandayo.
Okokugcina, usayizi wegridi kufanele uhlanganyele nosayizi wenkambu yokucabanga ye-X-ray Machine. Usebenzisa igridi emincane kakhulu ingaholela ku-cutoff yegridi, lapho imiphetho yegridi ivimba ugongolo lwe-x-ray, okuholela kwikhwalithi yesithombe esingesihle. Ngakolunye uhlangothi, igridi enkulu kakhulu ingahle ingalingani kahle noma yandise umthamo wesiguli ngokungadingekile.
Ekuphetheni, ukukhetha okulungileIgridi ye-X-rayNgomshini wakho we-X-ray ubalulekile ukuthola imiphumela ephezulu yokucabanga. Izici ezinjenge-grid ratio, imvamisa, impahla, uhla olugxile, nosayizi kufanele kubhekwe ngokucophelela ukuqinisekisa ukusebenza kahle. Ukubonisana nayeImishini ye-X-rayAbakhiqizi noma ochwepheshe be-radiology banganikeza ukuqondiswa okubalulekile ekukhetheni igridi ye-X-ray efanelekile yezidingo zakho ezithile zokucabanga.
