Lefapheng la ho nka ditshwantsho tsa bongaka, tshebediso yali-collimator tsa X-ray tse iketsange fetotse tsela eo litsebi tsa tlhokomelo ea bophelo li hapang litšoantšo tsa boleng bo holimo ha li ntse li netefatsa polokeho le boiketlo ba mokuli. Lisebelisoa tsena tse tsoetseng pele li na le likarolo tse fapaneng tse eketsang bokhoni, ho nepahala le ts'ebetso ka kakaretso. E 'ngoe ea likarolo ke potoloho ea tieho ea kahare e timang tleloubu ka bo eona kamora metsotsoana e 30 ea ts'ebeliso, e bolokang matla le ho lelefatsa bophelo ba tleloubu. Ho phaella moo, khokahano ea mechini pakeng tsa collimator le tube ea X-ray e bonolo ebile ea tšepahala, ka tokiso e bonolo le sebaka se nepahetseng. Ho feta moo, mabone a LED a kopantsoeng lebaleng la leseli le bonahalang a netefatsa khanya e phahameng, e fellang ka litšoantšo tse hlakileng le tse qaqileng haholoanyane.
Potoloho ea ka hare ea tieho ea X-ray collimator e iketsang ke tšobotsi ea bohlokoa e e khethollang ho li-collimator tsa setso. Tšobotsi ena ha e boloke matla feela empa e boetse e atolosa bophelo ba tleloubu ka ho tima tleloubu ka bo eona kamora nako e behiloeng. Sena se molemo haholo libakeng tse maphathaphathe tsa bongaka moo lisebelisoa tsa X-ray li sebelisoang khafetsa letsatsi lohle. Bokhoni ba ho boloka matla le ho fokotsa makhetlo a ho nkeloa sebaka ha tleloubu ha bo thuse feela ho boloka litšenyehelo, empa hape bo fokotsa nako ea ho se sebetse ha tlhokomelo, e leng se lumellang bafani ba tlhokomelo ea bophelo ho tsepamisa maikutlo ho faneng ka tlhokomelo e nakong le e sebetsang ho bakuli.
Ho phaella moo, kgokelo ya mechini pakeng tsa X-ray collimator e iketsang le tube ya X-ray e etseditswe ho ba bonolo le ho tshepahala. Ditsebi tsa tlhokomelo ya bophelo di ka fetola collimator habonolo ho fihlella boholo le sebaka seo di se batlang sa pono, ho netefatsa hore mahlaseli a X-ray a lebiswa ka nepo sebakeng seo di se ratang. Boemo bona ba ho nepahala bo bohlokwa ho fumaneng ditshwantsho tsa boleng bo hodimo ha ka nako e ts'oanang ho fokotsa ho pepesehela mahlaseli bakeng sa bakudi le ditsebi tsa tlhokomelo ya bophelo. Bonolo ba tshebediso le moralo o matla wa mechini di etsa hore X-ray collimator e iketsang e be sesebediswa sa bohlokwa ditsing tsa ditshwantsho tsa bongaka, ho nolofatsa mosebetsi le ho eketsa tlhahiso ka kakaretso.
Ho phaella ho likarolo tsena, ho kopanya mabone a LED sebakeng se bonahalang sali-collimator tsa X-ray tse iketsange na le melemo e meholo. Theknoloji ea LED e fana ka khanya e phahameng le ponahalo e betere, e lumellang ho bona hantle sebopeho sa 'mele se nkiloeng setšoantšong. Sena se hlahisa litšoantšo tsa X-ray tse hlakileng le tse qaqileng haholoanyane, tse lumellang bafani ba tlhokomelo ea bophelo ho etsa liqeto tse nepahetseng tsa tlhahlobo le kalafo. Ho feta moo, mabone a LED a tsebahala ka ho tšoarella ha 'ona le ho sebelisa matla hantle, e leng se etsang hore e be khetho e tsitsitseng bakeng sa lits'ebetso tsa ho nka litšoantšo tsa bongaka.
Ka bokhutšoanyane, likarolo tse tsoetseng pele tse kang lipotoloho tsa tieho tsa kahare, likhokahano tse bonolo tsa mechini, le mabone a LED ho li-collimator tsa X-ray tse iketsang li emela tsoelo-pele e kholo theknolojing ea litšoantšo tsa bongaka. Likarolo tsena ha li thuse feela ho boloka matla le ho lelefatsa bophelo ba lisebelisoa, empa hape li ntlafatsa boleng le katleho ea mekhoa ea hau ea ho nka litšoantšo tsa X-ray. Ha mekhatlo ea tlhokomelo ea bophelo e ntse e tsoela pele ho beha tlhokomelo ea bakuli le bokhabane ba ts'ebetso pele, ho amoheloa ha li-collimator tsa X-ray tse iketsang ho tla bapala karolo ea bohlokoa ho bopeng bokamoso ba litšoantšo tsa bongaka.
