An I-X-ray grididlala indima ebalulekile ezithombeni zezokwelapha, isiza ekukhiqizeni izithombe zokuxilonga ezisezingeni eliphezulu.Njengoba ubuchwepheshe buqhubeka buthuthuka, isidingo sezindlela ezithuthukisiwe zokuthwebula izithombe sesibaluleke kakhulu.Lesi sihloko sizohlola indima yegridi ye-X-ray ekuthuthukiseni ukunemba nokucaca kwezithombe ze-X-ray.
I-X-ray grid, eyaziwa nangokuthi aIgridi ye-Bucky, iyithuluzi elisetshenziswa ku-radiography ukuthuthukisa ikhwalithi yezithombe ze-X-ray.Iqukethe imicu yokuhola emincane eqondaniswe ngephethini ye-crisscross, nento ephakathi nendawo emkhathini ekhanyayo phakathi.Umsebenzi oyinhloko wegridi ukumunca imisebe ehlakazekile ngaphambi kokuba ifinyelele esamukeli sesithombe, ngaleyo ndlela kwehliswe inani lemisebe esabalele enikela ekonakaleni kwesithombe.
Enye yezinzuzo ezibalulekile zokusebenzisa igridi ye-X-ray ikhono layo lokuthuthukisa ukugqama kwesithombe.Lapho i-X-ray idlula emzimbeni, ixhumana nezakhiwo ezihlukahlukene, okuholela emisebeni eyinhloko nehlakazekile.Nakuba imisebe eyinhloko iphethe ulwazi olubalulekile lokuxilonga, imisebe ehlakazekile ivame ukwehlisa izinga lesithombe.Ngokubeka igridi ye-X-ray phambi kwesamukeli sesithombe, imisebe ehlakazekile imunca ngokuphumelelayo, ivumela kuphela imisebe eyinhloko ewusizo ukuthi ifinyelele kumtshina.Ngenxa yalokho, umehluko phakathi kwezakhiwo ezahlukene esithombeni uyathuthukiswa, okuholela ekuxilongweni okucacile nokunembe kakhudlwana.
Ngaphezu kwalokho, igridi ye-X-ray isiza ekunciphiseni ubukhona bezithombe zobuciko.Ama-artifact ayizakhiwo ezingafuneki noma amaphethini avela ezithombeni zokuxilonga, okungenzeka ziholele ekuhumusheni okungalungile nasekufanekisweni okwengeziwe okungadingekile.Imisebe esabalele ingaba negalelo ekwakhekeni kwezinto zokwenziwa, njengemigqa yegridi noma izithombe eziyizipoki.Ngokumunca le misebe ehlakazekile, ama-X-ray grid anciphisa ukwenzeka kwezinto zobuciko ezinjalo, okuphumela ezithombeni ezihlanzekile nezithembekile.
Kubalulekile ukuqaphela ukuthi ukusetshenziswa kwegridi ye-X-ray kudinga ukuqondanisa okufanele.Uma ingaqondakali kahle, imichilo yokuhola yegridi ingavimbela imisebe eyinhloko, okuholela ekuthathweni kwesithombe okungaphelele kanye nokwehla kwekhwalithi yesithombe.Ngakho-ke, ama-radiographers kufanele aqinisekise ukuthi igridi ibekwe ngendlela efanele ngaphambi kokudalula isiguli kuma-X ray.Ukwengeza, amagridi angethula izinga elithile lokunqamuka kwegridi, okubhekisela ekwehleni kwemisebe eyinhloko emuncwa ngenxa yokungahambi kahle kwegridi noma amaphutha ekwakhiweni kwawo.Kubalulekile ukuthi ochwepheshe bezokunakekelwa kwempilo bayiqaphele le mikhawulo ukuze bagweme ukubeka engcupheni ikhwalithi yesithombe se-X-ray.
Ekugcineni, ukusetshenziswa kwe-I-X-ray gridkuthuthukisa kakhulu ukunemba nokucaca kwezithombe zokuxilonga.Ngokumunca ngokukhetha imisebe ehlakazekile, igridi ye-X-ray ithuthukisa ukugqama kwesithombe futhi inciphise ukuba khona kwama-artifact.Kodwa-ke, ukuqondanisa okulungile nokuqonda imikhawulo engaba khona kubalulekile ukuze kusetshenziswe kahle.Njengoba ubuchwepheshe buqhubeka buthuthuka, kulindeleke ukuthi ukuthuthukiswa okuqhubekayo ekwakhiweni kwegridi ye-X-ray kuzoba nomthelela kukhwalithi yesithombe engcono nakakhulu kanye nokunemba kokuxilonga emkhakheni wezithombe zezokwelapha.
