Urumva rwose imirasire itangwa na mashini ya X-ray?

Iterambere rya siyanse n’ikoranabuhanga hamwe n’iterambere ry’ikoranabuhanga mu buvuzi, amahirwe y’abantu bahura na X-X iyo bagiye mu bitaro nayo yariyongereye cyane.Buriwese azi ko igituza X-imirasire, CT, ultrasound yamabara na X-ray bishobora kohereza X-ray kugirango byinjire mumubiri wabantu kugirango babone indwara.Bazi kandi ko X-imirasire isohora imirasire, ariko ni bangahe bumva imashini za X-ray.Bite se ku mirasire yasohotse?
Ubwa mbere, ni gute X-imirasire muri anImashini ya X-raybyakozwe?Ibisabwa kugirango habeho X-ray ikoreshwa mubuvuzi nibi bikurikira: 1. Umuyoboro wa X-ray: umuyoboro wikirahure cya vacuum urimo electrode ebyiri, cathode na anode;2. Isahani ya Tungsten: tungsten yicyuma ifite numero ya atome nyinshi irashobora gukoreshwa mugukora imiyoboro ya X-ray Anode niyo ntego yo kwakira ibisasu bya electron;3. Electron zigenda kumuvuduko mwinshi: shyira voltage ndende kumpande zombi za X-ray kugirango electron zigende kumuvuduko mwinshi.Impinduramatwara yihariye izamura voltage nzima kuri voltage ikenewe.Isahani ya tungsten imaze gukubitwa na electron zigenda kumuvuduko mwinshi, atome ya tungsten irashobora kuba ioni muri electron kugirango ikore X-ray.
Icya kabiri, iyi X-ray imeze ite, kandi ni ukubera iki ishobora gukoreshwa mu kureba uko ibintu bimeze nyuma yo kwinjira mu mubiri w'umuntu?Ibi byose ni ukubera imiterere ya X-imirasire, ifite ibintu bitatu byingenzi:
1. Kwinjira: Kwinjira bivuga ubushobozi bwa X-ray yo kunyura mubintu bitiriwe.X-imirasire irashobora kwinjira mubikoresho urumuri rusanzwe rugaragara rudashobora.Umucyo ugaragara ufite uburebure burebure, na fotone ifite imbaraga nke cyane.Iyo ikubise ikintu, igice cyacyo kigaragarira, ibyinshi byinjizwa nibintu, kandi ntibishobora kunyura mubintu;mugihe X-imirasire itariyo, kubera uburebure bwayo buke, imbaraga Iyo imurika kubintu, igice gusa cyinjizwa nibikoresho, kandi ibyinshi byanduzwa binyuze mu cyuho cya atome, byerekana ubushobozi bukomeye bwo kwinjira.Ubushobozi bwa X-ray yo kwinjira mubintu bifitanye isano nimbaraga za fotora ya X-ray.Mugihe kigufi cyumurambararo wa X-imirasire, niko imbaraga za fotone nizindi mbaraga zinjira.Imbaraga zinjira muri X-imirasire nazo zijyanye n'ubucucike bwibintu.Ibikoresho byimbitse bikurura X-imirasire kandi ikohereza bike;ibikoresho bya denser bikurura bike kandi byohereza byinshi.Gukoresha uyu mutungo wo gutandukana gutandukanye, uturemangingo tworoshye nkamagufa, imitsi, hamwe namavuta afite ubucucike butandukanye birashobora gutandukanywa.Ngiyo ishingiro ryumubiri wa X-ray fluoroscopy no gufotora.
2. Ionisation: Iyo ikintu kirabagirana na X-ray, electron zidasanzwe zivanwa muri orbit ya atome.Ingaruka yitwa ionisation.Mubikorwa byamafoto yumuriro no gutatana, inzira ifotora na electroni ya recoil bitandukanijwe na atome zabo byitwa ionisation primaire.Izi fotoelectron cyangwa recoil electron zigongana nizindi atome mugihe cyurugendo, kuburyo electron ziva kuri atome zakubiswe bita ionisation ya kabiri.mu bintu bikomeye.Iyoni nziza kandi mbi ion izongera guhura vuba kandi ntabwo byoroshye gukusanya.Nyamara, amafaranga ionisiyasi muri gaze biroroshye kuyakusanya, kandi ingano yumuriro wa ionisiyoneri irashobora gukoreshwa kugirango hamenyekane ingano ya X-ray: Ibikoresho byo gupima X-bikozwe bishingiye kuri iri hame.Kubera ionisiyoneri, imyuka irashobora kuyobora amashanyarazi;ibintu bimwe na bimwe birashobora gukorerwa imiti;ingaruka zitandukanye zibinyabuzima zirashobora guterwa mubinyabuzima.Ionisation niyo shingiro ryangiza X-ray no kuvura.
3. Fluorescence: Bitewe n'uburebure buke bwa X-imirasire, ntibigaragara.Ariko rero, iyo irabagirana mubintu bimwe na bimwe nka fosifore, platine cyanide, zinc cadmium sulfide, calcium tungstate, nibindi, atome iba imeze neza kubera ionisiyoneri cyangwa kwishima, kandi atom zisubira mubutaka mubikorwa. , kubera urwego rwingufu zinzibacyuho ya valence electron.Itanga urumuri rugaragara cyangwa ultraviolet, arirwo fluorescence.Ingaruka ya X-ray itera ibintu fluoresce yitwa fluorescence.Ubukomezi bwa fluorescence buringaniye nubunini bwa X-X.Ingaruka nizo shingiro ryo gukoresha X-ray kuri fluoroscopi.Mubikorwa byo gusuzuma X-ray, ubu bwoko bwa fluorescence burashobora gukoreshwa mugukora ecran ya fluorescent, kwerekana ecran, ecran yinjiza mumashusho yiyongera nibindi.Mugaragaza ya fluorescent ikoreshwa mugukurikirana amashusho ya X-ray inyura mubice byabantu mugihe cya fluoroscopi, kandi ecran ikomeza ikoreshwa mugukomeza sensibilité ya firime mugihe cyo gufotora.Ibyavuzwe haruguru ni rusange muri X-imirasire.
