Ngenxa yokuhambela phambili kwenzululwazi nobuchwepheshe kunye nophuhliso lobuchwephesha bezonyango, amathuba okuba abantu bajongwe kwiX-reyi xa besiya esibhedlele nawo ande kakhulu.Wonke umntu uyazi ukuba i-X-reyi yesifuba, i-CT, i-ultrasound yombala kunye noomatshini be-X-reyi banokukhupha ii-X-reyi ukungena emzimbeni womntu ukujonga isifo.Bayazi nokuba iiX-reyi zikhupha imitha, kodwa bangaphi abantu abaziqonda ngokwenene oomatshini beX-reyi.Kuthekani ngemitha ekhutshiweyo?
Okokuqala, zinjani ii-X-reyi kwi-Umatshini weX-reyiiveliswe?Iimeko ezifunekayo ukuveliswa kwee-X-rays ezisetyenziselwa amayeza zimi ngolu hlobo lulandelayo: 1. I-X-ray tube: i-tube ye-vacuum yeglasi equkethe i-electrodes ezimbini, i-cathode kunye ne-anode;2. Ipleyiti ye-Tungsten: i-tungsten yensimbi enenombolo ephezulu ye-athomu ingasetyenziselwa ukwenza iityhubhu ze-X-ray I-anode yinjongo yokufumana i-electron bombardment;3. Ii-electron ezihamba ngesantya esiphezulu: sebenzisa amandla ombane aphezulu kuzo zombini iziphelo zetyhubhu ye-X-ray ukwenza ii-electron zihambe ngesantya esiphezulu.Iziguquli ezikhethekileyo zonyusa amandla ombane ophilayo ukuya kumbane ophakamileyo ofunekayo.Emva kokuba ipleyiti ye-tungsten ibethwe zii-electron ezihamba ngesantya esiphezulu, iiathom ze-tungsten zinokufakwa kwi-elektroni ukuze zenze ii-X-reyi.
Okwesibini, iyintoni na le X-ray, kwaye kutheni ingasetyenziselwa ukujonga imeko emva kokungena emzimbeni womntu?Konke oku kungenxa yeempawu zeX-reyi, ezineempawu ezintathu eziphambili:
1. Ukungena: Ukungena kubhekisa ekukwazini kweeX-reyi ukudlula kwinto ngaphandle kokufunxwa.I-X-reyi inokungena kwizinto ezingenakukwazi ukukhanya okuqhelekileyo okubonakalayo.Ukukhanya okubonakalayo kunobude obude, kwaye iiphoton zinamandla amancinane kakhulu.Xa ibetha into ethile, inxalenye yayo ibonakaliswa, uninzi lwayo lufunxwa yi-matter, kwaye ayikwazi ukudlula kwinto;ngelixa i-X-reyi ingekho, ngenxa yobude bawo obufutshane, amandla Xa ikhanya kwizinto eziphathekayo, inxalenye kuphela efunxayo yimpahla, kwaye ininzi yayo idluliselwa nge-athom gap, ibonisa amandla anamandla okungena.Ubuchule beX-reyi bokugqobhoza izinto bunxulumene namandla eefoton zeX-reyi.Okukhona bufutshane ubude bamaza eX-reyi, kokukhona amandla ephoton aba makhulu kwaye kokukhona anamandla agqobhozayo.Amandla okungena e-X-ray nawo anxulumene nokuxinana kwezinto.Izinto ezixineneyo zifunxa ii-X-reyi ezininzi kwaye zigqithise kancinci;izinto ezixineneyo zifunxa kancinci kwaye zisasaze ngaphezulu.Ukusebenzisa le propati yokudibanisa okungafaniyo, izicubu ezithambileyo ezifana namathambo, izihlunu kunye namafutha anobunzima obuhlukeneyo bunokwahlulwa.Esi sisiseko somzimba we-X-ray fluoroscopy kunye nokufota.
2. Iionization: Xa into ifakwe kwi-X-reyi, ii-electron ze-extranuclear ziyasuswa kwi-athom orbit.Esi siphumo sibizwa ngokuba yi-ionization.Kwinkqubo yempembelelo ye-photoelectric kunye nokusabalalisa, inkqubo apho i-photoelectrons kunye ne-recoil electrons zihlukaniswe kwii-athomu zazo zibizwa ngokuba yi-ionization yokuqala.Ezi photoelectrons okanye i-recoil electrons zingqubana nezinye iiathom ngelixa zihamba, ukuze ii-electron ezisuka kwii-athom ezibethayo zibizwe ngokuba yi-ionization yesibini.kwizinto eziqinileyo nakulwelo.I-ionized positive and negative ions iya kuphinda idibanise ngokukhawuleza kwaye akulula ukuyiqokelela.Nangona kunjalo, umrhumo we-ionized kwigesi kulula ukuqokelela, kwaye inani lentlawulo ye-ionized lingasetyenziselwa ukucacisa inani le-X-ray exposure: Izixhobo zokulinganisa i-X-ray zenziwe ngokusekelwe kulo mgaqo.Ngenxa ye-ionization, iigesi zinokuqhuba umbane;izinto ezithile zinokudibana neekhemikhali;Iziphumo ezahlukeneyo zebhayoloji zinokungeniswa kwizinto eziphilayo.Ionization isisiseko somonakalo we-X-ray kunye nonyango.
3. I-Fluorescence: Ngenxa yobude obufutshane be-X-reyi, ayibonakali.Nangona kunjalo, xa i-irradiated kwiikhompawundi ezithile ezifana ne-phosphorus, i-platinum cyanide, i-zinc cadmium sulfide, i-calcium tungstate, njl. , ngenxa yenguqu yenqanaba lamandla ee-electron ze-valence.Ikhupha ukukhanya okubonakalayo okanye kwe-ultraviolet, okuyi-fluorescence.Isiphumo se-X-reyi ebangela ukuba izinto zibe ne-fluoresce kuthiwa yi-fluorescence.Ubunzulu be-fluorescence buhambelana nomthamo we-X-reyi.Esi siphumo sisisiseko sokusetyenziswa kwe-X-rays kwi-fluoroscopy.Kumsebenzi wokuxilonga i-X-ray, olu hlobo lwe-fluorescence lunokusetyenziswa ukwenza isikrini se-fluorescent, isikrini sokuqinisa, isikrini sokufaka kwi-intensifier yomfanekiso kunye nokunye.Isikrini se-fluorescent sisetyenziselwa ukujonga imifanekiso ye-X-reyi edlula kwizicubu zomntu ngexesha le-fluoroscopy, kwaye isikrini sokuqinisa sisetyenziselwa ukwandisa uvakalelo lwefilimu ngexesha lokufota.Oku kungasentla kukwazisa ngokubanzi kwi-X-reyi.
