Uma kukhulunywa ngokucabanga kwezokwelapha, ubuchwepheshe obubili obujwayelekile obusetshenzisiweAma-Flat Panel Detelna-Ukuqina kwesithombe. Zombili lezi zibuchwepheshe zisetshenziselwa ukuthwebula futhi zithuthukise izithombe ngezinjongo zokuxilonga, kepha zikwenza ngezindlela ezihlukile.
Ama-Flat Panel Detel Ziqukethe iphaneli elincanyana, elisicaba eliqukethe igridi yamaphikseli kanye nongqimba we-scintillator. Lapho ama-x-ray edlula emzimbeni futhi axhumana ne-scintillator, ikhipha ukukhanya, okulese kuguqulwa kube yisiginali kagesi ngamaphikiseli. Lesi siginali bese sicutshungulwa futhi sisetshenziselwe ukudala isithombe sedijithali.
Ngakolunye uhlangothi, kusetshenziswa izithombe zokuqina kwezithombe ku-fluoroscopy, inqubo evumela ukucabanga kwesikhathi sangempela kwezitho zomzimba ezishukumisayo. Ukuqina kwesithombe kusebenza ngokukhulisa ukukhanya okukhiqizwayo lapho ama-x-rays exhumana nesikrini se-phosphor. Ukukhanya okukhulisiwe bese kubanjwa yikhamera bese kusetshenzwa ukudala isithombe.
Omunye womehluko omkhulu phakathi kokutholwa kwephaneli eyisicaba kanye nokuqiniswa kwesithombe kuyindlela lapho aqala khona futhi acubungula izithombe. Ama-Flat Panel Detel Ukuqina kwesithombe, ngakolunye uhlangothi, kukhiqize izithombe ze-analog ezivame ukwehlisa ukulungiswa futhi zilungele kakhulu ukucabanga kwesikhathi sangempela.
Omunye umehluko phakathi kobuchwepheshe bobuchwepheshe bobabili ukuzwela kwabo kuma-X-ray. Ama-Flat Panel Detators azwela kakhulu ama-X-ray, avumela imithamo emisebe ephansi ukuthi isetshenziswe ngesikhathi sokucabanga. Lokhu kubaluleke kakhulu ezinqubweni zezingane nezisezingeni eliphakathi, lapho ukunciphisa ukuvezwa kwemisebe kubalulekile. Ukuqina kwesithombe, ngenkathi kusakwazi ukukhiqiza izithombe ezisezingeni eliphakeme, imvamisa idinga imithamo ephakeme yemisebe.
Ngokuya ngosayizi nokungabizi, ama-flat panel Storictors akhudlwana futhi aphatheke kancane kunezithombe ezikhulisa. Lokhu kungenxa yokuthi ama-flat panel detectors aqukethe indawo enkulu engaphezulu yokuthwebula izithombe, kanti ama-ukuqina wesithombe avame ukuba yincane futhi alula kakhulu, abenze balungele izinhlelo zokusebenza ze-mobile.
Izindleko futhi ziyisici okufanele sizicabangele lapho siqhathanisa imishini yokuthola iphaneli nezithombe. Ama-Flat Panel Detel Kodwa-ke, izindleko eziphakeme zokutholwa kwephaneli yephaneli zivame ukulungiswa ngekhwalithi yazo ephakeme yesithombe kanye nezidingo zedosi lemisebe ephansi.
Sekukonke, zombili izithonjana zephaneli eyisicaba kanye nezilungiselelo zezithombe zinezinzuzo zazo nokubi, kanye nokukhetha phakathi kobuchwepheshe bobabili kuncike ezidingweni ezithile zezithombe zezempilo. Ngenkathi imishini yokuthola iphaneli yephaneli ilungele kakhulu ukucabanga okuphezulu kwedijithali, ukuqina kwesithombe kungcono nge-fluoroscopy real-time futhi kuphaphatheke kakhulu futhi kungabizi. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, kungenzeka ukuthi bobabili ubuchwepheshe buqhubeke nokwenza ngcono futhi buhlangane embonini yezokwelapha.
