Kwicandelo lezonyango zanamhlanje, ukuthathwa kwemifanekiso kudlala indima ebalulekileyo ekunyamekeleni izigulana, okuvumela iingcali zempilo ukuba zibone izakhiwo zangaphakathi zomzimba. Phakathi kweendlela ezahlukeneyo zokuthathwa kwemifanekiso, ukuthathwa kwemifanekiso ye-X-ray kuseyeyona ndlela isetyenziswa kakhulu. Eyona nto iphambili kule teknoloji yityhubhu ye-X-ray yezonyango, isixhobo esitshintshe indlela esixilonga ngayo nesinyanga ngayo iimeko zonyango.
Yintoni ityhubhu ye-X-ray yezonyango?
A ityhubhu ye-X-ray yezonyangoyityhubhu ekhethekileyo ye-vacuum evelisa ii-X-reyi ngokusebenzisana kwee-electron ezinamandla aphezulu kunye nezinto ezijoliswe kuzo, ezihlala zenziwe nge-tungsten. Xa kusetyenziswa umbane, ii-electron zikhutshwa kwi-cathode eshushu kwaye zikhawuleziswe ziye kwi-anode. Emva kokubetha i-anode, ezi electron zikhawulezayo ziyangqubana nezinto ezijoliswe kuzo, zivelise ii-X-reyi kule nkqubo. Le ndlela isisiseko isivumela ukuba sibambe imifanekiso yamathambo, amalungu, kunye nezicubu emzimbeni womntu.
Izinto ezisetyenziswa kwiityhubhu ze-X-Ray
Ukuqonda izinto ezikwityhubhu ye-X-ray yezonyango kubalulekile ukuze kuqondwe umsebenzi wayo. Ezona zinto ziphambili ziquka:
- I-Cathode: Eli candelo liqulathe i-filament efudunyezwayo ukuze ivelise ii-electron. I-cathode ibalulekile ekuqaliseni inkqubo yokuvelisa i-X-ray.
- I-anode: I-anode isebenza njengendawo ekujoliswe kuyo i-cathode ukuze ikhuphe ii-electron. Ihlala yenziwe nge-tungsten ngenxa yokuba inyibilika kakhulu kwaye isebenza kakuhle ekuveliseni ii-X-ray.
- Imvulophu yeglasi okanye yesinyithi: Lonke eli qela libekwe kwi-vacuum-vacuum-vacuum envelope, ethintela ii-electron ukuba zingangqubani neemolekyuli zomoya kwaye iqinisekisa ukuveliswa kwe-X-ray okusebenzayo.
- Ukucoca: Ukuphucula umgangatho womfanekiso kunye nokunciphisa ukuvezwa kwesigulane kwimitha engeyomfuneko, kusetyenziswa izihluzo ukususa ii-X-rays ezingenamandla aneleyo ezinganikeli ulwazi lokuxilonga.
- I-Collimator: Esi sixhobo sibumba kwaye sinciphise umqadi we-X-reyi, siqinisekisa ukuba kuphela iindawo ezifunekayo ezivezwayo ngexesha lokufota.
Ukubaluleka kweetyhubhu ze-X-Ray kwiNtlalo
Iityhubhu ze-X-ray zonyango zibaluleke kakhulu kwiimeko ezahlukeneyo zeklinikhi. Zineendlela ezahlukeneyo zokusetyenziswa eziquka:
- Ukuxilongwa kokwaphuka kwamathambo: Ii-X-reyi zezona ziphambili zokuthatha imifanekiso yabantu abakrokrelwayo ukuba baqhekeke kwaye zinokuhlola umonakalo wamathambo ngokukhawuleza nangokuchanekileyo.
- Ukufunyanwa kwethumba: I-X-ray imaging inokunceda ekuchongeni ukukhula okungaqhelekanga okanye iithumba, nto leyo ekhokela iinkqubo ezongezelelweyo zokuxilonga.
- Imifanekiso yamazinyo: Kwi-dentistry, iityhubhu ze-X-ray zisetyenziselwa ukufota imifanekiso yamazinyo kunye nezakhiwo ezingqongileyo ukunceda ekuxilongeni iingxaki zamazinyo.
- Imifanekiso yesifuba: Ii-X-ray zesifuba zihlala zisetyenziselwa ukuvavanya imeko yemiphunga, ubungakanani bentliziyo, kunye nezinye iingxaki zesifuba.
Inkqubela phambili kwiTekhnoloji yeX-Ray Tube
Intsimi yemifanekiso yezonyango iyaqhubeka nokukhula, kunye netekhnoloji enxulumene neetyhubhu ze-X-ray. Inkqubela phambili yakutshanje ibandakanya ukuphuhliswa kweenkqubo ze-X-ray zedijithali eziphucula umgangatho womfanekiso, zinciphise ukuvezwa kwimitha, kwaye zinciphise amaxesha okucubungula. Ukongeza, ubuchwepheshe obutsha obufana noomatshini be-X-ray abaphathwayo benza ukuba imifanekiso ibe nokwenzeka kwiindawo ezahlukeneyo, kubandakanya amagumbi ongxamiseko kunye neendawo ezikude.
ukuququmbela
Iityhubhu ze-X-ray zonyangoziyinxalenye ebalulekileyo yokufota ngemifanekiso, zibonelela iingcali zezempilo ngezixhobo abazidingayo ukuze zenze izigqibo ezinolwazi malunga nokhathalelo lwezigulane. Njengoko ubuchwepheshe buqhubeka buphucuka, amandla eetyhubhu ze-X-ray aya kuqhubeka ephucuka, nto leyo ekhokelela ekuchanekeni okukhulu kokuxilongwa kunye neziphumo eziphuculweyo zezigulane. Ukuqonda umsebenzi kunye nokubaluleka kwezi zixhobo kubalulekile kuye nabani na onomdla kwicandelo lezonyango, njengoko zimele isiseko sendlela yokuxilonga yanamhlanje. Nokuba kusezibhedlele, kwiikliniki okanye kwiiofisi zamazinyo, iityhubhu ze-X-ray zonyango ziya kuhlala ziyinxalenye ebalulekileyo yokhathalelo lwempilo kwiminyaka ezayo.
