Xa kufikwa kumfanekiso wezonyango, zimbini iiteknoloji eziqhelekileyo ezisetyenziswayoiidetectors panel flatkwayeiziqinisekiso zomfanekiso.Zombini ezi teknoloji zisetyenziselwa ukubamba kunye nokuphucula imifanekiso ngeenjongo zokuxilonga, kodwa zikwenza oko ngeendlela ezahlukeneyo.
Ii-Flat panel detectors luhlobo lobuchwephesha bedijithali obusetyenziselwa ukufota imifanekiso ye-X-reyi.Ziquka ipaneli ecekethekileyo, esicaba equlethe igridi yeepikseli kunye ne-scintillator layer.Xa i-X-ray idlula emzimbeni kwaye isebenzisana ne-scintillator, ikhupha ukukhanya, okuye kuguqulelwe kwisignali yombane ngeepikseli.Olu phawu luyasetyenzwa luze lusetyenziswe ukwenza umfanekiso wedijithali.
Kwelinye icala, i-intensifiers yemifanekiso isetyenziswa kwi-fluoroscopy, ubuchule obuvumela umfanekiso wexesha lokwenyani wamalungu omzimba ashukumayo.Iziqinisekiso zomfanekiso zisebenza ngokwandisa ukukhanya okuveliswayo xa ii-X-rays zisebenzisana nesikrini se-phosphor.Ukukhanya kwe-amplified emva koko kuthathwe yikhamera kwaye kusetyenzwe ukwenza umfanekiso.
Omnye umahluko ophambili phakathi kwee-detectors zepaneli ezisicaba kunye ne-intensifiers yomfanekiso yindlela ababamba ngayo kwaye baqhube imifanekiso.Ii-detectors ze-flat panel ziyidijithali kwaye zivelisa imifanekiso enesisombululo esiphezulu esifanelekileyo kwi-imaging ye-static kunye ne-dynamic.Iziqinisekisi zomfanekiso, kwelinye icala, zivelisa imifanekiso ye-analog ehlala isezantsi kwisisombululo kwaye ifaneleke ngakumbi kumfanekiso wexesha lokwenyani.
Omnye umahluko phakathi kobu buchwepheshe bumbini bubuntununtunu babo kwi-X-reyi.Izixhobo zokubona iiphaneli ezicaba zinovakalelo ngakumbi kwiX-reyi, nto leyo evumela ukuba kusetyenziswe iidosi ezisezantsi zemitha ngexesha lomfanekiso.Oku kubaluleke ngakumbi kwiinkqubo zabantwana kunye neenkqubo zokungenelela, apho ukunciphisa ukuvezwa kwemitha kubalulekile.Iziqinisekisi zomfanekiso, ngelixa zisakwazi ukuvelisa imifanekiso ekumgangatho ophezulu, zifuna idosi ephezulu yemitha.
Ngokumalunga nobukhulu kunye nokuphatheka, izichongi zepaneli ezisicaba zikholisa ukuba zikhulu kwaye ziphathwa kancinane kuneziqinisekiso zomfanekiso.Oku kungenxa yokuba izichongi zephaneli ezisicaba ziqulethe indawo enkulu yomphezulu yokuthatha imifanekiso, ngelixa iziqinisekisi zemifanekiso zihlala zincinci kwaye zikhaphukhaphu ngakumbi, zizenza zifaneleke ngakumbi usetyenziso lwemifanekiso ephathwayo.
Iindleko zikwangumba omawuqwalaselwe xa uthelekisa izichongi zepaneli ezisicaba kunye neziqinisekiso zomfanekiso.Izixhobo zokubona iipaneli ezicaba zidla ngokubiza kakhulu kuneziqinisekiso zemifanekiso, nto leyo ezenza ukuba zifikeleleke lula kwezinye iindawo zokhathalelo lwempilo.Nangona kunjalo, amaxabiso aphezulu eedetectors zepaneli ezisicaba zihlala zithethelela umgangatho wazo ophakamileyo wemifanekiso kunye neemfuno zethamo lemitha esezantsi.
Lilonke, zombini izichongi zepaneli ezisicaba kunye neziqinisekisi zomfanekiso zineengenelo kunye nezinto ezingeloncedo zazo, kwaye ukhetho phakathi kobuchwephesha bumbini buxhomekeke kwiimfuno zokucinga ezithile zeziko lokhathalelo lwempilo.Ngelixa ii-detectors zephaneli ezisicaba zifaneleke ngakumbi kwi-high-resolution digital imaging, iziqinisekiso zemifanekiso zingcono kwi-fluoroscopy yexesha lokwenyani kwaye ziphathwa ngakumbi kwaye zingabizi kakhulu.Njengoko itekhnoloji iqhubeka nokuhambela phambili, kunokwenzeka ukuba zombini itekhnoloji iya kuqhubeka nokuphucula kwaye ihlalisane kushishino lokucinga lwezonyango.
