Tekinoroji yeX-ray yakashandura ndima yekufungidzira kwekurapa, ichipa nyanzvi dzekurapa ruzivo rwakakomba mumuviri wemunhu. Zvisinei, kushanda kwe X-ray imaging kunoenderana zvakanyanya nekururama kwemidziyo inoshandiswa, kunyanya X-ray collimators. Midziyo iyi inoita basa rakakosha mukuvandudza kurongeka kweradiological diagnostics nekudzora chimiro uye saizi yeX-ray danda, nekudaro kuderedza kuratidzwa kusingakoshi nekuvandudza kunaka kwemufananidzo.
Dzidza nezve X-ray collimators
X-ray collimatorsmidziyo inoiswa pachubhu yeX-ray inoshandiswa kuderedza mwaranzi inobuda panguva yekufungidzira. Nekudzikamisa nzvimbo yakafumurwa kuX-rays, macollimators anobatsira kutarisa radiation pane dzakati nzvimbo dzekufarira, izvo zvakakosha kuti uwane yakajeka uye yakadzama mifananidzo. Iyi nzira yakanangwa haingonatsiridza kunaka kwemifananidzo inogadzirwa, asi zvakare inoderedza dhizimisi yemwaranzi kune yakatenderedza tishu, nekudaro ichidzikisa njodzi yematambudziko ane chekuita neradiation.
Mifananidzo yakavandudzwa
Imwe yenzira huru iyo X-ray collimator inovandudza kuongororwa kweiyo nekuvandudza kunaka kwemufananidzo. Kana X-ray danda rikapinzwa, rinoderedza mwaranzi yakapararira, inogona kudzima ruzivo mumufananidzo. Kupararira kwemwaranzi kunoitika kana X-rays ichidyidzana nenyaya uye yotsauka kubva munzira yavo yekutanga, zvichikonzera mufananidzo usina kujeka paradiograph. Nekutarisisa danda necollimator, radiologists inogona kuwana yakajeka, yakakwirira-kusiyana mifananidzo, zvichiita kuti zvive nyore kuziva zvisiri izvo zvakaita semamota, kuputsika, kana hutachiona.
Deredza kuratidzwa kwemwaranzi
Pamusoro pekuvandudza mhando yemufananidzo, maX-ray collimators anoitawo basa rakakosha mukuderedza kuratidzwa kwemwaranzi yevarwere. Mwaranzi isingakoshi inoisa njodzi dzakakomba dzehutano, kunyanya panguva yekudzokorora maitiro ekufungidzira. Nekudzikamisa X-ray danda kunzvimbo yekufarira, iyo collimator inova nechokwadi chekuti inodiwa chete tishu inovhenekerwa. Izvi hazvingo chengetedza murwere chete, asi zvakare zvinoenderana neiyo ALARA (Sezvakaderera Sezvingabvira) nhungamiro, nhungamiro yakakosha muradiology ine chinangwa chekudzikisa kuratidzwa kwemwaranzi.
Kufambisa kuongororwa kwakarurama
Kuvandudza chimiro chemufananidzo uye kuderedza kuratidzwa kwemwaranzi kunonatsiridza zvakananga kuongororwa. Radiologists vanovimba nemifananidzo yemhando yepamusoro kuita sarudzo dzine ruzivo nezve kuchengetwa kwevarwere. Kana mifananidzo yakanyatsojeka uye isina zvigadzirwa zvinokonzerwa nemwaranzi yakapararira, zviri nyore kuona shanduko dzisinganzwisisiki muanatomy kana pathology. Kurongeka uku kunonyanya kukosha pakuongorora zvirwere zvakaita segomarara, uko kukasika kuona kunogona kukanganisa zvakanyanya kurapwa.
Muchidimbu
Muchidimbu,X-ray collimatorschishandiso chakakosha mumunda weradiology inogona kuvandudza zvakanyanya kuongororwa kwechokwadi. Nekutarisisa danda reX-ray, zvishandiso izvi zvinogona kuvandudza mhando yemufananidzo, kuderedza kuratidzwa kwemwaranzi isina kufanira, uye kufambisa kuongororwa kwakaringana. Sezvo tekinoroji ichiramba ichifambira mberi, macollimators acharamba achiita basa rakakosha mukuona kuti maitiro eradiology anoteedzera kumazinga epamusoro ekuchengetedzwa kwevarwere uye kuongororwa kwechokwadi. Iko kubatanidzwa kweinoshanda collimation tekinoroji haingobatsiri varwere chete, asi zvakare inogonesa vashandi vehutano kupa hutano huri nani kuburikidza nekufungidzira kwakaringana.
