Lefapheng la litšoantšo tsa bongaka, tšebeliso eali-collimator tse ikemetseng tsa X-raye fetotse tsela eo litsebi tsa tlhokomelo ea bophelo li nkang 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 ngata tse eketsang ts'ebetso, ho nepahala le ho sebetsa ka kakaretso. E 'ngoe ea likarolo ke potoloho ea tieho ea kahare e itimang tleloubu ka mor'a metsotsoana e 30 ea ts'ebeliso, e boloka matla le ho lelefatsa bophelo ba tleloubu.

Ho phaella moo, li-bulbs tse kopantsoeng tsa LED sebakeng sa leseli le bonahalang li tiisa khanya e phahameng, e hlahisang litšoantšo tse hlakileng le tse qaqileng haholoanyane.
Potoloho ea ka hare ea ho lieha ha collimator ea X-ray ke karolo ea bohlokoa e e khethollang ho li-collimator tsa setso. Karolo ena ha e boloke matla feela empa e boetse e lelefatsa bophelo ba tleloubu ka ho tima tleloubu ka bo eona ka mor'a nako e behiloeng. Sena se molemo ka ho khetheha libakeng tse phathahaneng tsa bongaka moo lisebelisoa tsa X-ray li sebelisoang khafetsa letsatsi lohle. Bokhoni ba ho boloka matla le ho fokotsa makhetlo a mangata a ho fetola li-bulb ha ho thuse feela ho boloka litšenyehelo, empa hape ho fokotsa nako ea tlhokomelo, ho lumella bafani ba tlhokomelo ea bophelo ho tsepamisa maikutlo ho fana ka tlhokomelo e nakong le e sebetsang ho bakuli.
Ntle le moo, khokahano ea mochini lipakeng tsa "automatic X-ray collimator" le X-ray tube e etselitsoe hore e be bonolo ebile e ka tšeptjoa.

Tšebeliso e bonolo le moralo o thata oa mochini o etsa hore li-X-ray collimators e be sesebelisoa sa bohlokoa litsing tsa litšoantšo tsa bongaka, ho tsamaisa mosebetsi le ho eketsa tlhahiso ka kakaretso.
Ho phaella ho likarolo tsena, ho kopanya li-bulbs tsa LED ka har'a mefuta e bonahalang eali-collimator tse ikemetseng tsa X-raye na le melemo e mengata.
