Umahluko phakathiiziqinisekiso zomfanekisokwayeiidetectors panel flat.Kwintsimi yeumfanekiso wezonyango, iiX-reyi zinendima ebalulekileyo ekuxilongeni nasekunyangeni izifo ezahlukahlukeneyo nokwenzakala.Ukuhambela phambili kwezobugcisa kukhokelele kuphuhliso lwezixhobo ezintsonkothileyo zokuthatha umfanekiso weX-reyi.Emibini enje ngokutsha ziziqinisekiso zomfanekiso kunye nezixhobo zokubona iipaneli ezisicaba.Nangona zombini ziyilelwe ukuphucula imifanekiso yeX-reyi, kukho umahluko omkhulu phakathi kobu buchwepheshe bumbini.
Ukuqonda umahluko, masiqale ngezinto zokuqinisa umfanekiso.Iziqinisekisi zemifanekiso zizixhobo ze-electro-optical eziqhele ukusetyenziswa kwinkalo yeradiology.Owona msebenzi wabo kukuphucula imifanekiso yeX-reyi, iyenze ibonakale iqaqambile kwaye ineenkcukacha ngakumbi.Umgaqo osebenzayo we-intensifier yomfanekiso kukuguqula iifotoni ze-X-ray zibe ziifotoni zokukhanya ezibonakalayo, ukwandisa ubukhulu bomfanekiso we-X-ray yasekuqaleni.
Inxalenye ephambili ye-intensifier yomfanekiso yi-phosphor yokufaka, ethatha iifoto ze-X-ray kwaye ikhuphe iifotoni ezikhanyayo ezibonakalayo.Ezi fotoni zikhawuleza kwaye zigxininise kwi-phosphor ephumayo, ukudala umfanekiso okhulisiwe.Lo mfanekiso mkhulu unokuthatyathwa yikhamera okanye uboniswe kwimonitha ngeenjongo zokuxilonga.Iziqinisekiso zemifanekiso zisebenza kakhulu ekuboneleleni ngemifanekiso yexesha lokwenyani kwaye zifanelekile kwiinkqubo ezifuna ukucinga ngexesha lokwenyani, njenge-fluoroscopy.
Ii-Flat panel detectors (FPDs) ziye zaba yindlela yokuqinisa umfanekiso.Izixhobo zokubona iiphaneli ezisicaba zizixhobo eziqinileyo ezithatha ngokuthe ngqo imifanekiso yeX-reyi zize ziyiguqule zibe ziimpawu zedijithali.Ngokungafaniyo neziqinisekiso zemifanekiso, ii-FPD azithembeli ekuguquleni iifoto ze-X-ray zibe ziifoto zokukhanya ezibonakalayo.Basebenzisa uthotho lweethin-film transistors (TFTs) ukuguqula iifoto zeX-ray zibe ziimpawu zombane.
Olona ncedo luphambili lwezichongi zephaneli ezisicaba kukukwazi ukuthatha imifanekiso yedijithali enesisombululo esiphezulu esinochasaniso oluphuculweyo kunye noluhlu oluguquguqukayo.Ezi zibonakaliso zedijithali zinokucutshungulwa ngokuthe ngqo kwaye ziboniswe kwikhompyutheni ukuze zihlalutywe ngokukhawuleza.Izixhobo zokubona iipaneli zeflethi zikwabonelela ngentsimi enkulu yokujonga kunye nokusebenza kakuhle komthamo (DQE) xa kuthelekiswa neziqinisekiso zemifanekiso, okukhokelela kumgangatho womfanekiso ophuculweyo.
Ii-detectors ze-Flat panel zibonelela ngeenzuzo ezibalulekileyo zokuguquguquka kunye nokuguquguquka.Zinokudityaniswa lula kwiinkqubo ze-X-ray ezikhoyo, zithathela indawo iziqinisekiso zemveli ngaphandle kohlengahlengiso olubanzi.
Umahluko phakathiX-ray umfanekiso intensifierskunye nezixhobo zokubona iipaneli ezisicaba zilele kubuchwephesha bazo obusisiseko kunye nokusebenza kwazo.Iziqinisekisi zemifanekiso zikhulisa imifanekiso yeX-reyi ngokuguqula iifoto zeX-reyi zibe ziifotoni zokukhanya ezibonakalayo, lo gama izixhobo zokubona iipaneli ezisicaba zibamba ngokuthe ngqo imifanekiso yeX-reyi zize ziyiguqulele kwimiqondiso yedijithali.Zombini iindlela zobugcisa zinenzuzo kunye nokungalunganga kwazo, kwaye ukukhetha phakathi kwazo kuxhomekeke kwiimfuno ezithile zokucinga, ukuqwalaselwa kweendleko, kunye nomgangatho womfanekiso ofunekayo.Zombini i-intensifiers yemifanekiso kunye ne-flat-panel detectors inceda ukuqhubela phambili intsimi ye-X-ray imaging kunye nokuphucula ukunakekelwa kwesigulane.
