Lefapheng le ntseng le tsoela pele la theknoloji ea litšoantšo tsa bongaka, ho nepahala le polokeho ke lintlha tse peli tsa bohlokoa tseo bafani ba tlhokomelo ea bophelo ba li etelletsang pele ha ba hlahloba le ho phekola bakuli. Har'a tsoelo-pele e kholo ea lisebelisoa tsa radiology, li-collimator tsa bongaka tsa X-ray li hlahella e le lisebelisoa tsa bohlokoa tšimong. Sesebelisoa sena se iqapetsoeng ha se netefatse feela ponahalo e nepahetseng ea likarolo tse ka hare empa hape se fokotsa ho pepeseha ha mahlaseli, ho fetola tlhokomelo ea bakuli.
Motheong oa eona, aX-ray collimator ea bongakake sesebelisoa se khomaretsoeng mochineng oa X-ray se bōpang le ho laola lebone la X-ray hore le tsepamise maikutlo likarolong tse itseng tsa ’mele oa mokuli. Ka ho fokotsa sekhahla sa marang-rang, litsebi tsa tlhokomelo ea bophelo bo botle li ka shebana hantle le libaka tse khahlang, tsa ntlafatsa ts'ebetso ea tlhahlobo ha li ntse li fokotsa ho pepeseha ha mahlaseli ho sa hlokahaleng libakeng tse ling.
E 'ngoe ea likarolo tse hlahelletseng tsa X-ray collimator ea bongaka ke ho nepahala ha tsona ho ke keng ha bapisoa. Kaha sesebelisoa sena se na le theknoloji e tsoetseng pele ea laser, se khona ho ikamahanya hantle le ho beha leballo la X-ray ntle le ho siea moeli oa phoso. Li-radiologists li ka fetola habonolo litlhophiso tsa collimator ho fumana boholo ba tšimo e lakatsehang, sebopeho sa seriti le angle, ho netefatsa ho nepahala ho phahameng litšoantšong tse hapiloeng.
Ho feta moo, theknoloji ena e tsoetseng pele e ntlafatsa tlhokomelo ea bakuli le polokeho ea basebetsi. Ka ho fokotsa mahlaseli a hasaneng, li-collimator tsa bongaka tsa X-ray li thibela ho pepeseha ho sa hlokahaleng ha lisele tse nang le kutloelo-bohloko sebakeng sa thahasello. Sena se ba bohlokoa haholo maemong a kotsing e kholo joalo ka mafu a bana le bakhachane, moo ho fokotsa lethal dose ea radiation ho leng bohlokoa haholo.
Ntle le ho nepahala le polokeho e ntlafalitsoeng, li-collimator tsa bongaka tsa X-ray tsa sejoale-joale li na le likarolo tse ngata tse ka ntlafatsang phallo ea mosebetsi oa radiology. Li-collimator tse ling li na le mohloli o hahelletsoeng ka har'a leseli o kenyang leseli 'meleng oa mokuli, e leng se thusang ho beha mahlaseli a X-ray hantle. Sena se fokotsa ho khutlisa le ho ntlafatsa matšeliso a mokuli nakong ea ho nka litšoantšo.
Ke habohlokoa ho hlokomela hore tsoelo-pele ea theknoloji ea collimator e boetse e lebisitse ho nts'etsopele ea li-collimator tse ikemetseng. Lisebelisoa tsena li sebelisa li-algorithms tse bohlale ho sekaseka sebaka sa radiographed le ho lokisa mahare a collimator ka nepo. Boiketsetso bona bo ntlafatsa ts'ebetso ea ts'ebetso, bo fokotsa liphoso tsa batho, 'me bo eketsa ts'ebetso ea mokuli ka kakaretso.
Bafani ba tlhokomelo ea bophelo bo botle ba ka boela ba rua molemo ka katleho ea litšenyehelo tsa li-collimator tsa X-ray tsa bongaka. Ka ho shebana hantle le libaka tse khahlang le ho fokotsa ho hasana ha mahlaseli ho sa hlokahaleng, mekhatlo ea tlhokomelo ea bophelo e ka ntlafatsa litšoantšo ha e ntse e fokotsa lethal dose ea mahlaseli le litšenyehelo tse amanang le eona. Ho phaella moo, ho nepahala ho eketsehileng ho ka ntlafatsa tsamaiso ea mokuli le ho fokotsa tlhokahalo ea mekhoa e eketsehileng ea litšoantšo.
Ka kakaretso,X-ray collimators ea bongakaba fetotse lefapha la radiology ka ho kopanya ho nepahala, polokeho le katleho. Sesebelisoa sena sa bohlokoa se netefatsa pono e nepahetseng ea libaka tseo ho shebiloeng ho tsona ha ho ntse ho fokotsa ho pepeseha ha mahlaseli ho bakuli le litsebi tsa bophelo bo botle. Ha thekenoloji e ntse e tsoela pele, re ka lebella lintlafatso tse ling tsa theknoloji ea collimator, ka hona re ntlafatsa boleng le polokeho ea litšoantšo tsa bongaka lefatšeng ka bophara. Ka ho tsetela ho li-collimator tsa bongaka tsa X-ray tsa phetoho, bafani ba tlhokomelo ea bophelo ba ka lula ba le ka pele ho radiology le ho fana ka tlhokomelo e ikhethang ea bakuli ha ba ntse ba ntlafatsa ts'ebetso ea ts'ebetso.
