Lefapheng la litšoantšo tsa bongaka, tšebeliso eali-collimator tse ikemetseng tsa X-raye bapala karolo ea bohlokoa ho netefatsa hore litšoantšo tsa tlhahlobo tse nepahetseng, tsa boleng bo holimo. Sesebelisoa sena se tsoetseng pele se etselitsoe ho laola boholo le sebōpeho sa mahlaseli a X-ray, kahoo se ntlafatsa ho hlaka ha setšoantšo le ho fokotsa ho pepeseha ha mahlaseli a mokuli. Ho blog ena, re tla hlahloba bohlokoa ba li-collimator tse ikemetseng tsa X-ray le phello ea tsona ts'ebetsong ea litšoantšo tsa bongaka.
E 'ngoe ea melemo e ka sehloohong ea li-collimator tsa X-ray ke bokhoni ba ho fokotsa boholo ba sefate sa X-ray sebakeng sa thahasello, kahoo ho fokotsa ho pepeseha ha mahlaseli ho sa hlokahaleng ho mokuli. Sena se bohlokoa haholo litšoantšong tsa bongaka, moo sepheo e leng ho fumana litšoantšo tse hlakileng le tse nepahetseng ha ho ntse ho fokotsa likotsi tse ka bang teng tse amanang le mahlaseli. Ka ho fetola li-parameter tsa collimation, sesebelisoa se etsa bonnete ba hore libaka tse hlokahalang feela li khantšitsoe, e leng se etsang hore ho be le ts'ebetso e sireletsehileng le e sebetsang haholoanyane ea ho nka litšoantšo.
Holim'a moo,li-collimator tse ikemetseng tsa X-ray phetha karolo ea bohlokoa ho ntlafatseng boleng ba setšoantšo. Ka ho laola sebōpeho le boholo ba mahlaseli a X-ray, li- collimator li thusa ho fokotsa mahlaseli a hasaneng, e leng se etsang hore ho be le litšoantšo tse hlakileng haholoanyane le tse qaqileng haholoanyane. Sena se bohlokoa bakeng sa tlhahlobo e nepahetseng le moralo oa kalafo, kaha o lumella litsebi tsa tlhokomelo ea bophelo ho tseba le ho sekaseka ka nepo lifokodi. Boleng bo ntlafetseng ba setšoantšo bo boetse bo lumella puisano e atlehang haholoanyane pakeng tsa litsebi tsa radiologists le litsebi tse ling tsa bongaka, qetellong e lebisa tlhokomelong e ntle ea bakuli.
Ntle le tšusumetso ea polokeho ea mokuli le boleng ba setšoantšo, li-collimator tse ikemetseng tsa X-ray li fana ka melemo e sebetsang ho bafani ba tlhokomelo ea bophelo. Sesebelisoa se nolofatsa ts'ebetso ea ho nka litšoantšo ka litlhophiso tsa ho thulana ka boiketsetso, ho boloka nako le boiteko ba litsebi tsa radiology. Sena ha se ntlafatse ts'ebetso ea ts'ebetso ea mosebetsi feela empa hape se fokotsa monyetla oa phoso ea motho, ho netefatsa liphello tse tsitsitseng le tse ka tšeptjoang tsa litšoantšo. Ka lebaka leo, mekhatlo ea tlhokomelo ea bophelo e ka ntlafatsa lisebelisoa tsa eona le ho fa bakuli maemo a holimo a tlhokomelo.
Haholo-holo, ts'ebeliso ea li-collimator tse ikemetseng tsa X-ray e tsamaellana le molao-motheo oa polokeho ea mahlaseli a ALARA (ka tlase kamoo ho ka khonehang), o totobatsang bohlokoa ba ho fokotsa ho pepeseha ha mahlaseli ntle le ho senya boleng ba tlhahlobo. Ka ho kenyelletsa theknoloji ena e tsoetseng pele ho li-protocol tsa bona tsa litšoantšo, bafani ba tlhokomelo ea bophelo bo botle ba bontša boitlamo ba bona ba tšireletso ea mokuli le tiiso ea boleng.
Ka kakaretso,li-collimator tse ikemetseng tsa X-rayke karolo ea bohlokoa ea litšoantšo tsa morao-rao tsa bongaka 'me li fana ka mefuta e mengata ea melemo e tlatsetsang lits'ebetsong tse sireletsehileng le tsa boleng bo phahameng ba tlhahlobo. Ho tloha ho fokotsa ho pepeseha ha mahlaseli ho ea ho ho ntlafatsa ho hlaka ha litšoantšo le ho nolofatsa phallo ea mosebetsi, sesebelisoa sena se tsoetseng pele se bapala karolo ea bohlokoa ho faneng ka tlhokomelo ea bophelo bo botle le e sebetsang hantle. Ha theknoloji e ntse e tsoela pele, li-X-ray collimators li lula e le sesebelisoa sa bohlokoa bakeng sa litsebi tsa bophelo bo botle tse inehetseng ho fana ka tlhokomelo e molemohali ho bakuli ba bona.
