Munyaya yemifananidzo yezvokurapa, kukosha kwekuderedza kusvibiswa nemwaranzi uye kuwedzera kushanda zvakanaka kwekuongorora hakufanirwe kutaurwa zvakanyanya. Chimwe chezvinhu zvakakosha mundima iyi kwave kuri kugadzirwa kwema X-ray collimators anongoerekana ashandiswa. Midziyo iyi yepamusoro inoita basa rakakosha mukusimudzira kuchengetedzeka kwevarwere uye kuvandudza kunaka kwemifananidzo ye X-ray.
Makorori eX-ray anozvigadzira egaZvakagadzirwa kuti zvigadzire uye zvigadzire dara reX-ray panzvimbo chaiyo, zvichideredza kuratidzwa kwemwaranzi kusingadiwi kune tishu dzakapoteredza. Ma collimator echinyakare anoda kugadziriswa nemaoko, izvo zvinowanzoita kuti dara rienderane uye mazinga ekushandiswa kwedara aenderane. Kusiyana neizvi, masisitimu ega anoshandisa tekinoroji yepamusoro, kusanganisira masensa uye ma algorithms esoftware, kugadzirisa collimation zvichienderana nechimiro chemuviri chiri kutorwa. Izvi hazvingorerutsi maitiro ekutora mifananidzo chete asiwo zvinoita kuti huwandu hwemwaranzi hurambe hwakaderera.
Chimwe chezvakanakira zvikuru zvema X-ray collimators anozvigadzira ega ndiko kugona kwawo kugadzirisa saizi dzakasiyana-siyana dzevarwere. Semuenzaniso, mumifananidzo yevana, njodzi yekusangana nemwaranzi inonyanya kunetseka nekuda kwekuwedzera kwekunzwa kwenyama yevana vadiki kumwaranzi ionizing. Automated collimator inogona kugadzirisa otomatiki saizi yemwaranzi nechimiro kuti ikwane saizi diki yemwana, ichideredza zvakanyanya mwero wemwaranzi uku ichiri kupa mifananidzo yepamusoro kuti iongororwe nemazvo.
Uyezve, macollimator aya ane tarisiro chaiyo uye mhinduro. Chinhu ichi chinoita kuti chero kutsauka kubva pakugadziriswa kwakanaka kwecollimation kugadziriswe nekukurumidza, zvichiwedzera kuchengetedzeka kwemurwere. Nekuramba uchiongorora maparamita emifananidzo, sisitimu iyi inobatsira vanachiremba ve radiation kuti varambe vachitevedzera nhungamiro dzekuchengetedza mwaranzi dzakasimbiswa, dzakadai semutemo weALARA (As Low As Reasonably Achievable).
Kubatanidza ma X-ray collimators otomatiki mukiriniki kunobatsirawo kuvandudza kushanda zvakanaka kwebasa. Nekushandisa ma X-ray collimation nemaoko, ma X-ray graphers anowanzo pedza nguva yakakosha achigadzirisa marongero uye kuona kuti akarongeka zvakanaka. Masisitimu emagetsi anoderedza mutoro uyu, zvichibvumira ma X-ray graphers kutarisa pakutarisira varwere nezvimwe zvinhu zvakakosha zvemafirimu. Kushanda uku hakungobatsiri chete vanopa hutano asiwo kunowedzera ruzivo rwevarwere nekuderedza nguva yekumirira uye kugadzirisa maitiro.
Pamusoro pekubatsira kwazvinoita pakuderedza mwaranzi, ma X-ray collimator anoshandawo pahutano kwenguva refu. Nekuderedza kuwanda kwemwaranzi, zvishandiso izvi zvinobatsira kuderedza njodzi yezvirwere zvinokonzerwa nemwaranzi zvakaita sekenza, kunyanya kune avo vanoda kuongororwa mifananidzo nguva nenguva, senge avo vane zvirwere zvisingaperi. Kuwanda kwekuwanda kwekuwanda kwemwaranzi kwenguva refu kunogona kuvandudza hutano uye kuderedza mari yekurapa inokonzerwa nematambudziko emwaranzi.
Muchidimbu,ma X-ray collimators anongoerekana aitikaZvinomiririra kufambira mberi kukuru mumifananidzo yezvokurapa, kunyanya mukuderedza kuratidzwa kwemwaranzi. Kugona kwavo kugadzirisa maitiro akasiyana-siyana emuviri wemurwere, kupa mhinduro chaiyo, uye kuwedzera kushanda zvakanaka kwebasa kunoita kuti vave maturusi akakosha muradiology. Sezvo tekinoroji ichiramba ichichinja, basa remasystem otomatiki mukuona kuchengetedzeka kwemurwere uye kuvandudza kururama kwekuongorora pasina mubvunzo richawedzera kuzivikanwa, zvichigadzira nzira yeramangwana remifananidzo yekurapa inoshanda uye yakachengeteka.
