Emkhakheni wezithombe zezokwelapha, ukunemba nokunemba kubaluleke kakhulu. Ama-X-ray collimators adlala indima ebalulekile ekuqinisekiseni ukuthi umsebe wemisebe uqondiswe ngokunembile endaweni okuqondiwe kuyo, okunciphisa ukuchayeka ezicutshini ezizungezile. Njengoba ubuchwepheshe buthuthuka, ukuthuthukiswa kwama-X-ray collimators azenzakalelayo kushintshe indlela ochwepheshe be-radiology kanye nochwepheshe abenza ngayo izinqubo zokuthwebula izithombe. Lesi sihloko sihlola umehluko phakathi kwama-collimators azenzakalelayo kanye nawasetshenziswa ngesandla, siqokomisa izinzuzo kanye nemikhawulo yawo ngamunye.
Iyini i-X-ray collimator?
Ama-collimator e-X-rayyimishini efakwe emishinini ye-X-ray esiza ekwakheni nasekunciphiseni umsebe we-X-ray. Ngokulawula usayizi nesimo somsebe, ama-collimator anciphisa ukuvezwa kwemisebe okungadingekile ezigulini nakubasebenzi bezokwelapha. Aphinde athuthukise ikhwalithi yesithombe ngokunciphisa imisebe ehlakazekile, engafihla imininingwane yokuxilonga.
I-collimator eyenziwe ngesandla: indlela yendabuko
Ama-collimator enziwe ngesandla abe yindinganiso ku-radiology iminyaka eminingi. Lawa madivayisi adinga ukuthi umqhubi alungise izilungiselelo ze-collimator ngesandla ngaphambi kokuhlolwa kwe-X-ray ngakunye. Uchwepheshe kumele aqondise i-collimator endaweni eqondiwe ngokubonakalayo, ngokuvamile echaza insimu yokubuka ngomsebe. Nakuba ama-collimator enziwe ngesandla elula futhi engabizi kakhulu, anemikhawulo ethile.
Enye yezinto ezimbi kakhulu ngama-collimator esandla ukuthi kungenzeka kube nephutha lomuntu. Ukwehluka kwendlela yokusebenza kungabangela ukungalingani kokulungiswa kwemisebe, okungaholela ekuchayekeni ngokweqile noma okunganele kwesiguli. Ngaphezu kwalokho, ukulungiswa ngesandla kungadla isikhathi, ikakhulukazi endaweni ematasa yezokwelapha lapho ukusebenza kahle kubalulekile khona.
Ama-collimator e-X-ray azenzakalelayo: ikusasa lezithombe
Ama-collimator e-X-ray azenzakalelayo amelela intuthuko enkulu kwezobuchwepheshe bokuthwebula izithombe. Lawa madivayisi asebenzisa izinzwa eziyinkimbinkimbi kanye nama-algorithms ukulungisa ngokuzenzakalelayo izilungiselelo ze-collimation ngokusekelwe ku-anatomy ethile ethathwayo. Ngokuhlanganisa nesofthiwe yomshini we-X-ray, i-autocollimator ingathola usayizi nesimo sesifunda esithandwayo bese ilungisa umsebe ngokufanele.
Enye yezinzuzo ezibaluleke kakhulu zama-autocollimator yikhono lawo lokuthuthukisa ukuphepha kwesiguli. Ngokunciphisa ukuchayeka emisebeni okungadingekile, la madivayisi asiza ukuvikela iziguli emiphumeleni engaba khona yesikhathi eside yemisebe. Ngaphezu kwalokho, ama-autocollimator angathuthukisa ikhwalithi yesithombe ngokuqinisekisa ukuhambisana kahle kwemisebe, ngaleyo ndlela anciphise amathuba okuphinda kuthathwe ngenxa yekhwalithi yesithombe ephansi.
Umehluko omkhulu phakathi kwama-collimator enziwe ngesandla nama-autocollimator
Ukusebenza: Ama-collimator enziwe ngesandla adinga ukulungiswa ngesandla ngochwepheshe, kuyilapho ama-collimator ezenzakalelayo esebenza ngokusekelwe kumapharamitha asethiwe kanye nokuhlaziywa kwedatha yesikhathi sangempela.
UkunembaAma-Autocollimator anikeza ukunemba okukhulu ekuqondisweni kwemisebe, okunciphisa ingozi yamaphutha omuntu ahlobene nokulungiswa ngesandla.
Ukusebenza kahle: Indlela ezenzakalelayo yalezi zi-collimator inciphisa isikhathi sokusetha, okuwusizo kakhulu eminyangweni yezithombe ezisebenza ngobuningi obukhulu.
Izindleko: Nakuba izindleko zokuqala ze-autocollimator zingase zibe phezulu, zinamandla okonga izindleko ngokuhamba kwesikhathi ngokuthuthukisa imiphumela yesiguli nokunciphisa amazinga okuhlolwa kabusha.
UkuqeqeshwaAma-collimator enziwe ngesandla adinga ochwepheshe ukuba baqonde kahle amasu okuqondanisa, kuyilapho ama-collimator azenzakalelayo engenza inqubo yokuqeqesha ibe lula futhi afeze ukuhamba komsebenzi okulula kakhulu.
Ngokufigqiwe
Njengoba insimu ye-radiology iqhubeka nokukhula, ukwamukelwa kweama-collimator e-X-ray azenzakalelayokungenzeka ukuthi kwande. Nakuba ama-collimator enziwe ngesandla esebenzele imboni kahle amashumi eminyaka, izinzuzo zokwenza izinto ngokuzenzakalela (ukunemba okwandisiwe, ukuphepha kweziguli okuthuthukisiwe, kanye nokusebenza kahle okwandisiwe) kwenza kube yisizathu esinamandla sokuwafaka emikhubeni yesimanje yokuthwebula izithombe. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-collimator kubalulekile kochwepheshe bezokwelapha njengoba belwela ukunikeza iziguli zabo ukunakekelwa okungcono kakhulu.
