Izikhangeli zephaneli ezisicaba(FPD) baye baguqula ibala lemifanekiso yezonyango ngenxa yeenzuzo zabo kubuchule bokwenza imifanekiso yemveli.Ezi zichongi zibonelela ngemifanekiso ekwimo ephezulu enokukhanya okuncinci kwemitha, okuyenza ibe yinxalenye ebalulekileyo yenkqubo yeX-reyi yanamhlanje.Ukukhetha ubungakanani obufanelekileyo bomtshina wepaneli kwisicelo esithile seklinikhi kubalulekile kwiziphumo zoxilongo ezichanekileyo nezisebenzayo.Apha ngezantsi sixoxa ngezinto ekufuneka ziqwalaselwe xa ukhetha ubungakanani besixhobo esisicaba esisicaba esifanelekileyo.
Funda malunga nezikhangeli zephaneli ecaba:
Isikhangeli sephaneli esisicaba sisixhobo sombane esikwaziyo ukuthatha imifanekiso ye-X-reyi ngokuthe ngqo kwipleyiti ebhityileyo, nto leyo ephelisa imfuneko yokuthathwa kwemifanekiso yemveli esekwe kwifilimu.Ziquka iscintillator layer eguqula iiX-reyi zibe kukukhanya okubonakalayo, kunye nothotho lweephotodiode ezibona oku kukhanya zize zikuguqulele ekubeni yimiqondiso yombane.Ubungakanani bephaneli buchaphazela ngqo indawo yokujonga kunye nesisombululo somfanekiso ofunyenweyo.
Qwalasela izicelo zonyango:
Ukukhethwa kobukhulu bomtshina wepaneli yeflethi kuxhomekeke kakhulu kwisicelo seklinikhi kunye neemfuno zokucinga.Kwi-radiography ngokubanzi, i-standard flat panel detector ubukhulu be-17×17 intshi isetyenziswa ngokuqhelekileyo.Obu bukhulu bukhulu ngokwaneleyo ukugubungela iimviwo ezininzi zesiqhelo, kubandakanywa ii-x-reyi zesifuba kunye nokubonwa kwesisu.Nangona kunjalo, kwizicelo ezithile ezinje ngentelekelelo yokuphela okanye iradiyoloji yabantwana, isayizi encinci yesixhobo sokubona ipaneli (umz. 14×17 i-intshi) zibonelela ngokuqhutywa ngcono kunye nokuthuthuzela kwesigulana.
Isisombululo kunye nendawo yokujonga:
Enye into ephambili ekumiseleni ubungakanani besixhobo somtshina wepaneli sisisombululo esifunwayo kunye nentsimi yokujonga.I-higher-resolution flat-panel detectors inokuveza iinkcukacha ezicacileyo, ezifana nezakhiwo ezincinci zamathambo okanye izicubu ezithambileyo.Nangona kunjalo, kubalulekile ukwenza ulungelelwaniso phakathi kwesisombululo kunye nenkalo yembono.Ubungakanani obukhulu bomtshini wepaneli yepaneli yenza ukuba indawo ebanzi yokujonga, inciphise imfuno yokubeka kwakhona umtshina ngexesha lokucinga.Izikhangeli zepaneli ezincinci ezincinci zifanelekile kumfanekiso wogqaliselo apho kuphela iindawo ezithile kufuneka zihlolwe.
Ubungakanani begumbi kunye noFikelelo lweSigulana:
Xa kuqwalaselwa ubungakanani besixhobo sephaneli ecaba, kubalulekile ukuqwalasela indawo ebonakalayo ekhoyo kwisebe leradiology.Izixhobo zokubona izinto ezinkulu zinokufuna indawo eyongezelelekileyo yokuqhuba, ngakumbi kwiindawo ezixineneyo.Ukufikeleleka kwesigulana kunye nokuthuthuzela kukwayimibandela ebalulekileyo ekufuneka iqwalaselwe.Ii-detectors ezinobunzima zisenokungakhululeki kwizigulana, ngakumbi ezo zihamba kancinci, ngoko ke ii-detectors zepaneli ezisicaba ezincinci zilukhetho olufanelekileyo.
Uhlahlo lwabiwo-mali kunye nokuphucula okunokwenzeka:
Iindleko zihlala ziqwalaselwa ngokubalulekileyo xa ukhetha nasiphi na isixhobo sonyango.Izixhobo zokubona iipaneli ezinkulu ezisicaba zidla ngokubiza kakhulu, ngoko ke kubalulekile ukuvavanya uhlahlo lwabiwo-mali lwakho kunye nokubakho kwemali.Kwakhona, kufanelekile ukuqwalasela ukuguquguquka kokuphuculwa kwexesha elizayo.Ezinye iisistim zomkhangeli wepaneli ezisicaba zibonelela ngokhetho lokutshintsha indawo yepaneli yesichongi ngaphakathi kweyunithi enye, evumela uphuculo kwipaneli yesisombululo esikhulu okanye esiphezulu ngaphandle kokubuyisela inkqubo yonke.
ukuququmbela:
Ukukhetha ubungakanani obuchanekileyo bomtshina wepaneli yepaneli kubalulekile kwiziphumo zomfanekiso ofanelekileyo kuxilongo lwezonyango.Ukuqwalaselwa kwesicelo seklinikhi, isisombululo, intsimi yokujonga, indawo yomzimba, induduzo yesigulane, kunye nohlahlo lwabiwo-mali luya kunceda ukukhokela isigqibo xa ukhetha ubungakanani be-flat panel detector.Ukubonisana nomenzi wesixhobo sonyango okanye ingcali enamava ngeradiyoloji kusoloko kucetyiswa ukuqinisekisa olona khetho lufanelekileyo kwimfuno yomfanekiso ngamnye.
