Lefapheng la litšoantšo tsa bongaka, bohlokoa ba ho fokotsa ho pepeseha ha mahlaseli a kotsi le ho eketsa ts'ebetso ea ts'oaetso e ke ke ea fetisoa. E 'ngoe ea likhatelo-pele tsa bohlokoa lefapheng lena e bile nts'etsopele ea li-collimator tse ikemetseng tsa X-ray. Lisebelisoa tsena tse tsoetseng pele li phetha karolo ea bohlokoa ho ntlafatsa tšireletseho ea bakuli le ho ntlafatsa boleng ba litšoantšo tsa X-ray.
Li-collimator tse ikemetseng tsa X-rayli etselitsoe hore li bōpe ka nepo le ho koalla mahlaseli a X-ray sebakeng seo ho shebiloeng ho sona, ho fokotsa ho pepesehela mahlaseli ho sa hlokahaleng liseleng tse e potolohileng. Li-collimator tsa setso li hloka ho lokisoa ka letsoho, tse atisang ho lebisa tlhokomelong e sa tsitsang ea maballo le maemo a ho pepeseha. Ka lehlakoreng le leng, litsamaiso tse ikemetseng li sebelisa theknoloji e tsoetseng pele, ho kenyeletsoa li-sensor le li-algorithms tsa software, ho fetola ka matla ho kopana ho ipapisitse le sebopeho se ikhethileng se bonts'itsoeng. Sena ha se nolofatse mokhoa oa ho nka litšoantšo feela empa hape se tiisa hore lethal dose ea mahlaseli e lula e fokola.
E 'ngoe ea melemo ea mantlha ea li-collimator tsa X-ray ke bokhoni ba tsona ba ho ikamahanya le mefuta e mengata ea boholo le libopeho tsa mokuli. Ka mohlala, litšoantšong tsa bana, kotsi ea ho pepesetsoa mahlaseli a kotsi e ameha haholo-holo ka lebaka la ho eketseha ha kutloisiso ea lisele tsa bana ba banyenyane ho mahlaseli a ionizing. Collimator e itirisang e ka khona ho fetola boholo ba balm le sebopeho ka bo eona ho amohela boholo bo nyane ba ngoana, ea fokotsa haholo lethal dose ea radiation ha e ntse e fana ka litšoantšo tsa boleng bo holimo bakeng sa tlhahlobo e nepahetseng.
Ho feta moo, li-collimator tsena li na le tlhahlobo ea nako ea nnete le maikutlo. Tšobotsi ena e tiisa hore ho kheloha leha e le hofe ho tloha boemong bo nepahetseng ba ho thulana ho lokisoa hang-hang, ho matlafatsa ts'ireletso ea mokuli le ho feta. Ka ho tsoela pele ho lekola liparamente tsa ho nahana, sistimi e itirisang e thusa litsebi tsa radiology ho boloka melao-motheo ea ts'ireletso ea mahlaseli a kotsi, joalo ka molao-motheo oa ALARA (E le Tlase Joalo ka Tsela e Atlehang).
Ho kopanya li-collimator tse ikemetseng tsa X-ray ho boikoetliso ba bongaka le hona ho thusa ho ntlafatsa katleho ea mosebetsi. Ka ho kopana ka letsoho, li-radiographer hangata li qeta nako ea bohlokoa li lokisa litlhophiso le ho etsa bonnete ba hore li tsamaisana hantle. Mekhoa e ikemetseng e fokotsa moroalo ona, e lumellang li-radiographers hore li tsepamise maikutlo tlhokomelong ea mokuli le likarolo tse ling tsa bohlokoa tsa mokhoa oa ho nka litšoantšo. Ts'ebetso ena ha e thuse feela bafani ba tlhokomelo ea bophelo bo botle empa hape e ntlafatsa phihlelo ea mokuli ka kakaretso ka ho fokotsa nako ea ho leta le ho ntlafatsa mekhoa.
Ntle le melemo ea hona joale ea phokotso ea mahlaseli, li-X-ray collimator tse ikemetseng le tsona li phetha karolo ea bohlokoa bophelong ba nako e telele. Ka ho fokotsa ho pepeseha ha mahlaseli, lisebelisoa tsena li thusa ho fokotsa kotsi ea mafu a bakoang ke mahlaseli a kotsi a kang kankere, haholo-holo ho ba hlokang tlhahlobo ea litšoantšo khafetsa, joalo ka ba nang le maemo a sa foleng. Kakaretso ea litlamorao tsa ho pepesetsoa mahlaseli nako e telele e ka ntlafatsa bophelo bo botle le ho fokotsa litšenyehelo tsa kalafo tse amanang le mathata a mahlaseli.
Ka kakaretso,li-collimator tse ikemetseng tsa X-raye bontša tsoelo-pele e kholo litabeng tsa bongaka, haholo-holo ho fokotsa ho pepeseha ha mahlaseli. Bokhoni ba bona ba ho ikamahanya le maemo a fapaneng a bakuli, ho fana ka maikutlo a nako ea nnete, le ho ntlafatsa ts'ebetso ea ts'ebetso ho ba etsa lisebelisoa tsa bohlokoa ho radiology. Ha thekenoloji e ntse e tsoela pele ho fetoha, karolo ea mekhoa e ikemetseng ea ho etsa bonnete ba tšireletseho ea mokuli le ho ntlafatsa ho nepahala ha ho hlahlojoa ha ho pelaelo hore e tla hlahella le ho feta, e behele tsela bakeng sa bokamoso ba litšoantšo tsa bongaka tse sebetsang hantle le tse sireletsehileng.
