Uma kuziwa ekucabangeni kwezokwelapha, ubuchwepheshe be-X-ray buyithuluzi eliyigugu elinganikeza ulwazi olubalulekile lokuxilonga.Imishini ye-X-ray iqukethe izingxenye eziningana, futhi isici esisodwa esibalulekile yileI-X-ray grid.Igridi ye-X-ray isetshenziselwa ukuthuthukisa ikhwalithi yesithombe ngokunciphisa imisebe ye-scatter kanye nokuthuthukisa ukugqama kwesithombe.Ukukhetha igridi ye-X-ray efanele yakhoUmshini we-X-raykubalulekile ukuze kuqinisekiswe imiphumela enembile necacile yezithombe.Kulesi sihloko, sizoxoxa ngezinto okufanele uzicabangele lapho ukhetha igridi ye-X-ray yomshini wakho we-X ray.
Ngaphambi kokuthi sijule enqubweni yokukhetha, ake siqonde izisekelo zegridi ye-X-ray.Igridi ye-X-ray iyithuluzi elakhiwe ngemichilo emincane yomthofu eshintshana nezinto ezikhanyayo.Umsebenzi oyinhloko wegridi ukumunca imisebe ye-scatter ephakama lapho ama-X-ray photon ehlangana nomzimba wesiguli.Imisebe ye-scatter inganciphisa kakhulu ikhwalithi yesithombe ngokukhiqiza ingemuva elimnyama elaziwa ngokuthi “imigqa yegridi.”Ngokumunca imisebe ye-scatter, amagridi e-X-ray asiza ekuthuthukiseni ukugqama kwesithombe, okuholela ezithombeni ezibukhali.
Isici esibaluleke kakhulu okufanele icatshangelwe lapho ukhetha igridi ye-X-ray isilinganiso sayo.Isilinganiso segridi sisho ubude bemigqa yokuhola uma kuqhathaniswa nebanga eliphakathi kwayo.Izilinganiso zegridi ezivame kakhulu ngu-6:1, 8:1, 10:1, kanye no-12:1.Izilinganiso zegridi eziphakeme zinikeza ukumuncwa okungcono kwemisebe ye-scatter kodwa kudinga izici eziphezulu ze-X-ray tube technique.Ngokuvamile, isilinganiso segridi esingu-10:1 noma esingu-12:1 silungele i-radiography evamile, njengoba isusa ngokuphumelelayo imisebe esakazwayo ngaphandle kokwenyusa umthamo wesiguli ngokweqile.
Esinye isici esibalulekile ifrikhwensi yegridi, emelela inani lemigqa yomthofu iyintshi noma isentimitha.Amafrikhwensi egridi aphezulu aphumela emicu yokuhola emincane nemincane, ethuthukisa ikhwalithi yesithombe kodwa andise izindleko zegridi ye-X-ray.Ifrikhwensi yegridi yemigqa engu-103 iyintshi ngayinye noma imigqa engu-40 ngesentimitha ngokuvamile isetshenziselwa i-radiography evamile.Kodwa-ke, amafrikhwensi egridi aphezulu, njengemigqa engu-178 iyintshi ngayinye noma imigqa engu-70 ngesentimitha, ayanconywa ezinhlelweni zokusebenza zezithombe ezikhethekile ezidinga ikhwalithi yesithombe ephezulu.
Ngaphezu kwesilinganiso segridi kanye nemvamisa, izinto zegridi nazo zibalulekile.Izinto ezihlukahlukene, njenge-aluminium, i-carbon fibre, namagridi ayi-hybrid, asetshenziswa ekukhiqizeni amagridi e-X-ray.Amagridi e-aluminium yiwona asetshenziswa kakhulu ngenxa yezindleko zawo kanye nekhono elihle lokumunca.Nokho, zivame ukuba nzima futhi zingabangela ukuwohloka kwesithombe uma zingaqondani kahle ne-X-ray beam.Amagridi e-carbon fibre ayisindi futhi ahlinzeka ngezakhiwo ezinhle kakhulu zokumunca, kodwa abiza kakhulu.Amagridi amaHybrid ahlanganisa izinzuzo zako kokubili i-aluminium ne-carbon fiber grids, enikeza ibhalansi enhle phakathi kwezindleko nokusebenza.
Kubalulekile futhi ukucabangela ububanzi bokugxila begridi, obubhekisela kububanzi bamabanga we-X-ray tube-to-grid lapho igridi isebenza kahle kakhulu.Imishini ehlukene ye-X-ray inezidingo ezihlukene zobubanzi obugxilile, futhi ukukhetha igridi efana nokucaciswa komshini wakho kubalulekile.Ukusebenzisa igridi ngaphandle kwebanga lokugxila elinconyiwe kungaholela kukhwalithi yesithombe ephansi kanye nokwenyuka komthamo wesiguli.
Okokugcina, usayizi wegridi kufanele uhambisane nosayizi wenkundla yokuthwebula yomshini we-X-ray.Ukusebenzisa igridi encane kakhulu kungaholela ekunqamukeni kwegridi, lapho amaphethelo egridi evimba i-X-ray, okuholela kukhwalithi yesithombe empofu.Ngakolunye uhlangothi, igridi enkulu kakhulu ingase ingalingani kahle noma inyuse umthamo wesiguli ngokungadingekile.
Ekugcineni, ukukhetha okulungileI-X-ray gridngoba umshini wakho we-X-ray ubalulekile ukuze uthole imiphumela yezithombe zekhwalithi ephezulu.Izinto ezifana nesilinganiso segridi, imvamisa, okokusebenza, ububanzi obugxilile, nosayizi kufanele kucatshangelwe ngokucophelela ukuze kuqinisekiswe ukusebenza okuphezulu.Ukubonisana neImishini ye-X-rayabakhiqizi noma ochwepheshe be-radiology bangakunikeza isiqondiso esibalulekile ekukhetheni igridi ye-X-ray efanele yezidingo zakho ezithile zesithombe.
