I-X-ray imaging iyithuluzi elibalulekile lokuxilonga kwezokwelapha, elivumela ochwepheshe bezokunakekelwa kwempilo ukuthi babone futhi bahlole izimo zezokwelapha ezihlukahlukene.Isiqinisi isithombe, ingxenye ebalulekile yemishini ye-X-ray, sidlala indima ebalulekile ekuthuthukiseni ikhwalithi nokucaca kwalezi zithombe.Kulesi sihloko, sizohlola ubukhulu be-Iziqinisekisi zesithombe ze-X-raykanye nokuthi baba nesandla kanjani ekuthuthukisweni kobuchwepheshe bezithombe zezokwelapha.
Ama-X-ray image intensifiers amathuluzi akhethekile aguqula imisebe ye-X-ray ibe isithombe esibonakalayo.Lawa ma-intensifiers aqukethe izingxenye ezimbalwa, okuhlanganisa i-phosphor yokufaka, i-photocathode, i-electron optics, kanye ne-phosphor ephumayo.I-phosphor yokufaka ivezwa emisebeni ye-X-ray futhi ikhipha ama-photon alula, abese eguqulwa abe ama-electron nge-photocathode.Ama-electron optics akhulisa futhi agxilise lawa ma-electron, awaqondise ngase-phosphor ephumayo, lapho aguqulwa khona abuyele ekukhanyeni okubonakalayo, okuholela esithombeni esiqinile.
Obunye bobukhulu obubalulekile be-X-ray image intensifiers indawo engaphezulu yokufaka.Lobu bukhulu bunquma usayizi wenkundla yemisebe ye-X-ray engathathwa bese iguqulwa ibe isithombe.Ngokuvamile, usayizi wendawo yokufaka isuka ku-15 kuya ku-40 amasentimitha ububanzi, okuvumela ukuhlalisa izingxenye ezihlukahlukene zomzimba nezidingo zesithombe.Kubalulekile ukuthi indawo yokufaka ihambisane nezidingo zesithombe ukuze kuqinisekiswe ukuxilonga okunembile nokuphelele.
Ukwengeza, ukushuba kongqimba lwe-phosphor okokufaka bunye ubukhulu obubalulekile be-X-ray image intensifiers.Ugqinsi lwalesi sendlalelo sinquma ukusebenza kahle kokuguqulwa kwama-X-ray photons abe ukukhanya okubonakalayo.Izendlalelo ze-phosphor zokufakwayo ezacile zivame ukunikeza ukulungiswa okuphezulu kwendawo, okuvumela ukutholwa nokuboniswa kwezakhiwo ezincane ngaphakathi komzimba.Kodwa-ke, izingqimba ze-phosphor zokufaka ezijiyile zivame ukukhethwa ezimweni lapho ukuzwela okwengeziwe ngemisebe kuyadingeka.
Ngaphezu kwalokho, usayizi nokuma kwezithombe ze-X-ray zidlala indima ebalulekile ekuhlanganisweni kwazo nezinhlelo ze-X-ray kanye nokunethezeka kweziguli.Lezi zilinganiso zidinga ukuthuthukiswa ukuze kuqinisekiswe ukuma okulula nokuqondanisa phakathi nokuhlolwa.Iziqinisekiso zesithombe ezincane nezilula zivumela ukuguquguquka okukhulu nokuhleleka, zisize ochwepheshe bezokunakekelwa kwempilo ekuthwebuleni izithombe ezifiswayo ngempumelelo.Ukwengeza, i-ergonomics yomumo ifaka isandla ekududuzeni kweziguli, ukunciphisa ukunyakaza okungadingekile kanye nokungahambi kahle okungenzeka ngesikhathi sezinqubo ze-X-ray.
Ngaphandle kobukhulu bomzimba, ikhwalithi yesithombe ekhiqizwe ama-X-ray eqinisa isithombe ibalulekile enqubweni yokuxilonga.Ukulungiswa, ukugqama, nokukhanya kwezithombe eziqinisiwe kuthinta kakhulu ukunemba nokusebenza kokuxilongwa.Ukuthuthuka kobuchwepheshe bokuqinisa izithombe kuholele ekuthuthukisweni kwezitholi zedijithali, njengezitholi zephaneli eyisicaba, ezinikeza ukulungiswa kwendawo okuphezulu kanye nobubanzi obuguqukayo uma kuqhathaniswa neziqinisekisi zendabuko.Lezi zitholi zedijithali ziguqule izithombe ze-X-ray, okuvumela ikhwalithi yesithombe ethuthukisiwe kanye nokuzethemba okuthuthukisiwe kokuxilonga.
Sengiphetha, iziqinisekiso zezithombe ze-X-ray ziyizingxenye ezibalulekile zobuchwepheshe bezithombe zezokwelapha.Ubukhulu balezi ziqinisi, okuhlanganisa indawo engaphezulu yokokufaka, ukujiya kongqimba lwe-phosphor okokufaka, nosayizi nokuma, yizici ezibalulekile ezithonya ikhwalithi nokusebenza kwezithombe ze-X-ray.Ukwengeza, intuthuko kwezobuchwepheshe ilethe izitholi zedijithali ezinikeza ikhwalithi yesithombe ephezulu.Njengoba izithombe zezokwelapha ziqhubeka nokuguquka, lezi zilinganiso zizodlala indima ebalulekile ekuqhubekiseni imingcele yamakhono okuxilonga, ekugcineni kuholele ekunakekelweni kwesiguli okungcono kanye nemiphumela.
