Itekhnoloji ye-X-reyi ibe sisixhobo esibalulekileyo kushishino lokhuseleko. Iimatshini ze-X-reyi zoKhuseleko zibonelela ngendlela engaphazamisiyo yokubona izinto ezifihliweyo okanye izinto eziyingozi kwimithwalo, iipakethi kunye neekhonteyina. Eyona nto iphambili kumatshini we-x-reyi wokhuseleko yityhubhu ye-x-reyi, evelisa ii-x-reyi ezinamandla aphezulu ezisetyenziswa ekuskeni.
Iityhubhu ze-X-rayzisetyenziswa kwiintlobo ngeentlobo zezicelo kwi-radiography, kwi-medical imaging, kwi-materials science, nakwi-industrial analysis. Nangona kunjalo, kwishishini lokhuseleko, ii-X-ray tubes zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko loluntu, ukuthintela ubugrogrisi kunye nokuphucula ukhuseleko.
An Ityhubhu ye-X-reyisisixhobo se-elektroniki esiguqula amandla ombane abe yi-X-rays enamandla aphezulu ukuze kuthathwe imifanekiso. Le tube ine-cathode kunye ne-anode evalekileyo kwigumbi le-vacuum. Xa umbane udlula kwi-cathode, ukhupha umjelo wee-electron, ezikhawuleziswa ziye kwi-anode. Ii-electron zingqubana ne-anode, zivelise ii-X-rays ezijoliswe kwinto ehlalutywayo.
Oomatshini be-X-ray bokhuseleko basebenzisa iintlobo ezimbini zeetyhubhu ze-X-ray: iityhubhu zesinyithi ze-ceramic (MC) kunyeiityhubhu ze-anode ezijikelezayo (RA). Ityhubhu ye-MC isetyenziswa kakhulu kuba ingabizi kakhulu, ihlala ixesha elide kwaye ithembekile. Ivelisa umqadi we-X-reyi ozinzileyo nophantsi ofanelekileyo wokuthatha imifanekiso yezinto zezinto ezinoxinano oluphantsi. Kwelinye icala, iityhubhu ze-RA zinamandla ngakumbi kuneetyhubhu ze-MC kwaye zivelisa umqadi we-X-reyi oqinileyo ophezulu. Ifanelekile ukuskena izinto ezinezixhobo ezinoxinano oluphezulu ezifana nesinyithi.
Ukusebenza kwetyhubhu ye-X-ray kumatshini we-X-ray wokhuseleko kuchatshazelwa zizinto ezininzi, kubandakanya i-voltage yetyhubhu, i-tube current, kunye nexesha lokuvezwa. I-voltage yetyhubhu imisela amandla e-X-rays eveliswayo, ngelixa i-tube current ilawula ubungakanani be-X-rays eveliswayo ngexesha leyunithi nganye. Ixesha lokuvezwa limisela ixesha le-X-rays ejoliswe kwinto ehlalutywayo.
Ezinye iimatshini ze-X-reyi zokhuseleko zisebenzisa itekhnoloji yokujonga i-X-reyi enamandla amabini, esebenzisa iityhubhu ezimbini ze-X-reyi ezinamanqanaba ahlukeneyo amandla. Ityhubhu enye ivelisa ii-X-reyi ezinamandla aphantsi, ngelixa enye ivelisa ii-X-reyi ezinamandla aphezulu. Umfanekiso ophumayo ubonisa imibala eyahlukeneyo ebonisa uxinano kunye nenani leathomu lento nganye kumfanekiso oskeniweyo. Le teknoloji ivumela abaqhubi ukuba bahlule phakathi kwezinto eziphilayo nezingaphiliyo, nto leyo ephucula ukubonwa kwezinto ezifihliweyo.
Ngamafutshane, iityhubhu ze-X-ray zisisiseko somatshini wokhuseleko we-X-ray, zinceda ekuchongeni izinto ezifihlakeleyo, iziqhushumbisi, kunye nezinto eziyingozi. Zibonelela ngendlela ekhawulezayo, esebenzayo nengaphazamisiyo yokuskena imithwalo, iipakethi kunye neekhonteyina. Ngaphandle kweetyhubhu ze-X-ray, ukuhlolwa kokhuseleko kuya kuba yinkqubo enzima nethatha ixesha, okwenza ukugcina ukhuseleko loluntu kunye nokuthintela ubugrogrisi kube nzima. Ke ngoko, uphuhliso lwetekhnoloji yeetyhubhu ze-X-ray luhlala lubalulekile kwikamva loomatshini bokhuseleko be-X-ray.
