Tekinoroji yeX-ray yakachinja zvakanyanya basa rekutora mifananidzo yezvekurapa, ichipa nyanzvi dzezvekurapa ruzivo rwakakosha nezvemuviri wemunhu. Zvisinei, kushanda kwekutora mifananidzo yeX-ray kunoenderana zvakanyanya nekunyatsorongeka kwemidziyo inoshandiswa, kunyanya maX-ray collimators. Midziyo iyi inoita basa rakakosha mukuvandudza kururama kwekuongorora kweX-ray nekudzora chimiro nehukuru hwemwenje weX-ray, nokudaro ichideredza kuratidzwa kusingakoshi uye kuvandudza kunaka kwemufananidzo.
Dzidza nezve X-ray collimators
Maekisirei ekugadzira macollimatorzvishandiso zvakaiswa pachubhu yeX-ray zvinoshandiswa kuderedza mwaranzi inoburitswa panguva yekutora mifananidzo. Nekuganhurira nzvimbo inoonekwa paX-ray, ma collimator anobatsira kutarisisa mwaranzi panzvimbo dzakakosha, izvo zvakakosha pakuwana mifananidzo yakajeka uye yakadzama. Nzira iyi yakanangwa haingogadzirisi mhando yemifananidzo inoburitswa chete, asiwo inoderedza mwero wemwaranzi kune tishu dzakapoteredza, nokudaro ichideredza njodzi yezvinetso zvine chekuita nemwaranzi.
Hunhu hwemufananidzo hwakavandudzwa
Imwe yenzira huru iyo X-ray collimator inovandudza kunyatsoongorora ndeyekuvandudza kunaka kwemufananidzo. Kana danda reX-ray rabviswa, rinoderedza mwaranzi yakapararira, iyo inogona kudzima ruzivo mumufananidzo. Mwaranzi yakapararira inoitika kana X-ray ikabatana nezvinhu uye ikatsauka kubva panzira yayo yekutanga, zvichikonzera mufananidzo usina kujeka paradiograph. Nekutarisa danda necollimator, vanachiremba ve radiology vanogona kuwana mifananidzo yakajeka, ine musiyano mukuru, zvichiita kuti zvive nyore kuona zvinhu zvisina kunaka zvakaita sebundu, kutyoka, kana hutachiona.
Deredza kuratidzwa kwemwaranzi
Pamusoro pekuvandudza kunaka kwemufananidzo, ma X-ray collimators anoitawo basa rakakosha mukuderedza kuratidzwa kwemwaranzi nemurwere. Mwaranzi isingakoshi inokonzera njodzi huru dzehutano, kunyanya panguva yekudzokorora mifananidzo. Nekuganhurira mwenje weX-ray kunzvimbo yaunoda, collimator inoita kuti tishu dzinodiwa chete dzipiswe nemwaranzi. Izvi hazvingodziviriri murwere chete, asiwo zvinotevedzera musimboti weALARA (As Low As Possible), gwara guru mu radiology rine chinangwa chekuderedza kuratidzwa kwemwaranzi nemwaranzi.
Kubatsira kuongororwa kwechirwere nemazvo
Kuvandudza hunhu hwemufananidzo uye kuderedza kuratidzwa kwemwaranzi kunovandudza zvakananga kunyatsoongorora. Nyanzvi dze radiation dzinoshandisa mifananidzo yepamusoro kuti dziite sarudzo dzine ruzivo nezvekutarisirwa kwevarwere. Kana mifananidzo yakajeka uye isina zvinhu zvakavezwa zvinokonzerwa nemwaranzi yakapararira, zviri nyore kuona shanduko dzisinganzwisisike muhunhu hwemuviri kana pathology. Kururama uku kwakakosha zvikuru pakuongorora zvirwere zvakaita sekenza, uko kuonekwa nekukurumidza kunogona kukanganisa zvakanyanya mhedzisiro yekurapa.
Muchidimbu
Muchidimbu,Maekisirei ekugadzira macollimatorchishandiso chakakosha mumunda weX-ray chinogona kuvandudza zvikuru kururama kwekuongorora. Nekutarisa X-ray beam, zvishandiso izvi zvinogona kuvandudza kunaka kwemufananidzo, kuderedza kuratidzwa kwemwaranzi kusingakoshi, uye kuita kuti kuongororwa kwakarurama kuve nyore. Sezvo tekinoroji ichiramba ichifambira mberi, macollimator acharamba achiita basa rakakosha mukuona kuti maitiro eX-ray anotevedzera mwero wepamusoro wekuchengetedzeka kwemurwere uye kururama kwekuongorora. Kubatanidzwa kwetekinoroji inoshanda yecollimation hakungobatsiri varwere chete, asiwo kunoita kuti vashandi vehutano vape rubatsiro rwuri nani kuburikidza nemifananidzo chaiyo.
