Urumva rwose imirasire isohoka nimashini za x-ray?

Hamwe no gutera imbere kwa siyanse n'ikoranabuhanga no guteza imbere ikoranabuhanga ry'ubuvuzi, amahirwe yabantu bahura na X-ray mugihe bagiye mubitaro na bo bariyongereye cyane. Umuntu wese azi icyo gituza x-imirasire, CT, ibara rya ultrasound na X-ray rishobora gusohora x-rays kugirango winjire umubiri wumuntu kugirango witegereze indwara. Bazi kandi ko x-rays yohereza imirasire, ariko ni bangahe basobanukiwe neza imashini za x-ray. Tuvuge iki ku mirasire yasohotse?
Ubwa mbere, nigute X-imirasire muri anX-ray imashinibyakozwe? Ibisabwa bisabwa kugirango umusaruro wa X-Imirasire ikoreshwa mubuvuzi ni ibi bikurikira: 1. 2. Isahani y'ibirayi: Icyuma cya Tungsten hamwe nomero ya atomic nyinshi birashobora gukoreshwa mugukora X-ray Tubes nintego yo kwakira ibisasu bya electron; 3. Electrons igenda kumuvuduko mwinshi: Koresha voltage ndende kumutwe wa X-ray kugirango electrons igenda kumuvuduko mwinshi. Impinduka zidasanzwe zazamutse voltage nzima kumuzimu usabwa. Nyuma yisahani ya Tungsten ikubitwa na electrons igenda kumuvuduko mwinshi, atome ya tungsten irashobora kuba ionised muri electrons kugirango ikore x-imirasire.
Icya kabiri, ni ubuhe bwoko bw'iyi X-ray, kandi ni ukubera iki byakoreshwa mu kwitegereza imiterere nyuma yo kwinjira mu mubiri w'umuntu? Ibi byose kubera imitungo ya X-imirasire, ifite ibintu bitatu byingenzi:
1. X-Imirasire irashobora kwinjiramo ibikoresho bisanzwe bigaragara. Umucyo ugaragara ufite uburebure burebure, kandi fotografike zifite imbaraga nke cyane. Iyo ikubise ikintu, igice cyacyo kiragaragara, ibyinshi muri byo byinjira ku kibazo, kandi ntigishobora kunyura mu kintu; Mugihe x-imirasire ntabwo, kubera uburebure buke bwabo, imbaraga zabo iyo imurika kubikoresho, gusa igice cyinjijwe nibikoresho, kandi igice kinini cyanduzwa nibikoresho bya atome, byerekana ubushobozi bukomeye bwimbere. Ubushobozi bwa X-Ray kugirango bwinjizwe neza bifitanye isano nimbaraga za x-ray fotografike. Kugabanya uburebure bwa x-imirasire, imbaraga nyinshi zamafoto na nkomeye imbaraga zinjira. Imbaraga zinjira za X-Imirasire nayo ifitanye isano nubucucike bwibikoresho. Ibikoresho byo kubohora bikurura byinshi x-imirasire mike; Ibikoresho byo kubohora bikurura bike kandi bikohereza byinshi. Ukoresheje uyu mutungo wo kwinjiza utandukanye, imyenda yoroshye nkamagufwa, imitsi, hamwe namakosa hamwe nibiti bitandukanye birashobora gutandukanywa. Ngiyo urufatiro rwumubiri rwa X-Ray Fluoscopy no gufotora.
2. Ionisation: Iyo ibintu bituzuye na X-imirasire, electronclear yakuwe muri orbit atome. Izi ngaruka zitwa ionisation. Mugihe cyingaruka zamafoto no gutatanya, inzira aho ifoto ya fotosilents hamwe na relectron ya electron yatandukanijwe na atome zabo yitwa Ionisation. Aya mafoto cyangwa rendil electron yagonganya nibindi bya atome mugihe cyurugendo, kugirango electron yo muri atome yitabyebwe ionisation. mubintu n'amazi. Ihanga rya Ionised Nion izatangira vuba kandi ntabwo byoroshye gukusanya. Ariko, amafaranga ya Ionised muri gaze biroroshye gukusanya, kandi umubare wibibazo bya Ioniable birashobora gukoreshwa kugirango umenye umubare wa X-ray. Kubera ionisation, imyuka irashobora gukora amashanyarazi; ibintu bimwe na bimwe birashobora gukorerwa imiti; Ingaruka zitandukanye zibinyabuzima zirashobora guterwa mubinyabuzima. Ionisation ni ishingiro ryangiza x-ray kwangirika no kuvurwa.
3. Fluorescence: Bitewe nuburebure buke bwa X-imirasire, ntibigaragara. Ariko, iyo induruye kubintu bimwe na bimwe nka fosiphorus, Platinum cyanide, igituba cya kalcium, nibindi, atome iri muburyo bwihariye kubera izo mbaraga za electron. Itanga urumuri rugaragara cyangwa ultraviolet, ni fluorescence. Ingaruka za X-Imirasire itera ibintu fluoresce yitwa Fluorescence. Ubukana bwa fluorescence ni ugereranije kugeza kuri x-imirasire. Ingaruka ni ishingiro ryo gusaba X-imirasire kuri flueroscopy. Muri X-ray yakazi, ubwo bwoko bwa fluorescence irashobora gukoreshwa mugukoresha fluorescent, gukaza ecran, kwinjiza ecran mubyiciro byishusho nibindi. Mugaragaza fluorescent ikoreshwa mukwitegereza amashusho ya X-Imirasire inyura mu bice byabantu mugihe cya flueroscopy, kandi ecran yo gukaza ikoreshwa muguhuza ibyiyumvo bya firime mugihe cyo gufotora mugihe cyo gufotora mugihe cyo gufotora mugihe cyo gufotora. Ibyavuzwe haruguru ni intangiriro rusange kuri x-imirasire.
