I-X-reyi imaging sisixhobo esibalulekileyo sokuxilonga kwezamayeza, esivumela iingcali zempilo ukuba zichonge kwaye zichonge iimeko ezahlukeneyo zonyango.Ukuqinisa umfanekiso, icandelo elibalulekileyo koomatshini beX-reyi, lidlala indima ebalulekileyo ekwandiseni umgangatho nokucaca kwale mifanekiso.Kweli nqaku, siza kuphonononga imilinganiselo yeX-ray umfanekiso intensifierskunye nendlela abanegalelo ngayo ekuphuhliseni iteknoloji yemifanekiso yezonyango.
Izinto zokuqinisa umfanekiso weX-reyi zizixhobo ezikhethekileyo eziguqula imitha yeX-reyi ibe ngumfanekiso obonakalayo.Ezi ziqinisi zibandakanya amacandelo amaninzi, kubandakanywa i-phosphor yegalelo, i-photocathode, i-electron optics, kunye ne-phosphor ephumayo.I-phosphor yegalelo ibonakaliswe kwimitha ye-X-ray kwaye ikhupha iifotoni ezikhanyayo, eziguqulwa zibe yi-electron nge-photocathode.I-electron optics ikhulisa kwaye igxininise ezi electron, zikhokelela kwi-phosphor ephumayo, apho ziguqulwa zibuyele ekukhanyeni okubonakalayo, okukhokelela kumfanekiso owenziwe ngamandla.
Enye yemilinganiselo ebalulekileyo ye-X-reyi yokuqinisa umfanekiso ngummandla wegalelo.Lo mlinganiso umisela ubungakanani bendawo yemitha yeX-reyi enokuthi ibanjwe kwaye iguqulwe ibe ngumfanekiso.Ngokuqhelekileyo, ubukhulu bendawo yokufaka igalelo buvela kwi-15 ukuya kwi-40 centimeters ububanzi, okuvumela ukuba kuhlaliswe iindawo ezahlukeneyo zomzimba kunye neemfuno zokucinga.Kubalulekile ukuba indawo yokufakwayo ihambelane neemfuno zemifanekiso ukuze kuqinisekiswe uxilongo oluchanekileyo nolubanzi.
Ukongezelela, ubukhulu boluhlu lwe-phosphor yegalelo ngomnye umlinganiselo obalulekileyo we-X-ray yokuqinisa umfanekiso.Ubukhulu bolu maleko bumisela ukusebenza kakuhle kokuguqulwa kweefotoni zeX-ray zibe kukukhanya okubonakalayo.Igalelo elincinci le-phosphor layers lidla ngokunikezela ngesisombululo esiphezulu sendawo, okwenza ukuba kubonwe kunye nokubonwa kwezakhiwo ezincinci ngaphakathi komzimba.Nangona kunjalo, iileya ze-phosphor ezityebileyo zihlala zikhethwa kwiimeko apho uvakalelo olongezelelweyo lwemitha luyimfuneko.
Ngaphaya koko, ubukhulu kunye nokumila kwe-X-reyi yokuqinisa umfanekiso kudlala indima ebalulekileyo ekudityanisweni kweenkqubo ze-X-reyi kunye nokuthuthuzela izigulane.Le milinganiselo kufuneka iphuculwe ukuqinisekisa ukubekwa lula nokulungelelaniswa ngexesha leemviwo.Imifanekiso emincinci kunye nekhaphukhaphu yokuqinisa ivumela ukuguquguquka okukhulu kunye nokuguquguquka, ukunceda abaqeqeshi bezempilo ukuba babambe imifanekiso efunekayo ngokufanelekileyo.Ukongezelela, i-ergonomics yokwakheka igalelo ekuthuthuzelekeni kwezigulane, ukunciphisa ukunyakaza okungadingekile kunye nokukhathazeka okunokwenzeka ngexesha leenkqubo ze-X-ray.
Ngaphandle kobukhulu bomzimba, umgangatho womfanekiso oveliswe zii-X-reyi zokuqinisa umfanekiso ubalulekile kwinkqubo yoxilongo.Isisombululo, umahluko, kunye nokuqaqamba kwemifanekiso eyomeleziweyo ichaphazela kakhulu ukuchaneka nokusebenza koxilongo.Ukuqhubela phambili kwitekhnoloji yokuqinisa imifanekiso kukhokelele kuphuhliso lwezichongi zedijithali, ezifana nezichongi zephaneli ecaba, ezibonelela ngesisombululo esiphezulu sesithuba kunye noluhlu oluguquguqukayo xa kuthelekiswa neziqinisekiso zemveli.Ezi zichongi zedijithali ziwuguqule umfanekiso weX-reyi, nto leyo evumela ukuphuculwa komgangatho womfanekiso kunye nokuzithemba okuphuculweyo kokuxilonga.
Ukuqukumbela, iziqinisekiso ze-X-reyi ziyinxalenye ebalulekileyo yetekhnoloji yemifanekiso yezonyango.Imilinganiselo yala ma-intensifiers, kubandakanywa indawo yokufaka igalelo, ubuninzi be-input phosphor layer, kunye nobukhulu kunye nokuma, zizinto eziphambili ezichaphazela umgangatho kunye nokusebenza kwemifanekiso ye-X-ray.Ukongeza, ukuqhubela phambili kwetekhnoloji kuzise ii-detectors zedijithali ezibonelela ngomgangatho womfanekiso ophakamileyo.Njengoko umfanekiso wezonyango uqhubeka nokuguquka, le milinganiselo iya kudlala indima ebalulekileyo ekutyhaleni imida yezakhono zokuxilonga, ekugqibeleni ikhokelela ekunyamekelweni kwesigulane kunye neziphumo.
