Izitholi zephaneli eziyisicaba(i-FPD) iguqule umkhakha wezithombe zezokwelapha ngenxa yezinzuzo zayo ngaphezu kwamasu omdabu wokuthwebula izithombe.Lezi zitholi zinikeza izithombe ezinokulungiswa okuphezulu ezinokuchayeka emisebeni okuncane, okuzenza zibe yingxenye ebalulekile yesistimu ye-X-ray yanamuhla.Ukukhetha umtshina wephaneli eyisicaba wosayizi olungile wohlelo oluthile lomtholampilo kubalulekile ukuze uthole imiphumela enembile nephumelelayo yokuxilonga.Ngezansi sixoxa ngezinto okufanele zicatshangelwe lapho kukhethwa usayizi womtshina wephaneli eyisicaba ofanele.
Funda mayelana nezitholi zephaneli eyisicaba:
Umtshina wephaneli eyisicaba iyisisetshenziswa se-elekthronikhi esikwazi ukuthwebula izithombe ze-X-ray ngqo epuletini elincanyana, okususa isidingo sokuthwebula isithombe esisekelwe kufilimu esivamile.Ahlanganisa ungqimba lwe-scintillator oluguqula ama-X-ray abe ukukhanya okubonakalayo, kanye noxhaxha lwama-photodiode athola lokhu kukhanya futhi akuguqule kube izimpawu zikagesi.Usayizi wephaneli uthinta ngqo inkambu yokubuka nokulungiswa kwesithombe esitholiwe.
Cabangela izicelo zomtholampilo:
Ukukhethwa kosayizi womtshina wephaneli eyisicaba kuncike kakhulu ekusetshenzisweni komtholampilo kanye nezidingo zesithombe.Ngokujwayelekile i-radiography, usayizi ojwayelekile womtshina wephaneli eyi-17x17 amayintshi uvame ukusetshenziswa.Lo sayizi mkhulu ngokwanele ukumboza izivivinyo eziningi ezijwayelekile, okuhlanganisa ama-x-reyi esifuba nokuthwebula kwesisu.Kodwa-ke, ezinsizeni ezithile ezifana ne-extremity imaging noma i-radiology yezingane, izitholi zephaneli eyisicaba ezinosayizi omncane (isb. 14×17 amayintshi) zinikeza ukulawuleka okungcono nokunethezeka kwesiguli.
Ukulungiswa kanye nenkundla yokubuka:
Esinye isici esibalulekile ekunqumeni usayizi womtshina wephaneli eyisicaba yisinqumo esifunwayo kanye nenkundla yokubuka.Izitholi zephaneli eyisicaba ezinokulungiswa okuphezulu zingaveza imininingwane ecolekile, njengezakhiwo ezincane zamathambo noma izicubu ezithambile.Nokho, kubalulekile ukulinganisa phakathi kwesinqumo nenkundla yokubuka.Usayizi omkhulu womtshina wephaneli eyisicaba wenza indawo yokubuka ebanzi, enciphisa isidingo sokubeka kabusha umtshina ngesikhathi sokuthwebula.Izitholi zephaneli eyisicaba emincane zilungele ukuthwebula okugxilile lapho kuphela izindawo ezithile ezidinga ukuhlolwa.
Ubukhulu Begumbi kanye Nokufinyeleleka Kwesiguli:
Uma ucubungula usayizi womtshina wephaneli eyisicaba, kubalulekile ukucabangela indawo ebonakalayo etholakala ngaphakathi komnyango we-radiology.Imitshina emikhulu ingase idinge indawo eyengeziwe yokuqondisa, ikakhulukazi ezindaweni eziminyene.Ukufinyeleleka kwesiguli nokunethezeka nakho kuyizici ezibalulekile okufanele zicatshangelwe.Izithungatha ezinomthamo zingase zingakhululeki ezigulini, ikakhulukazi lezo ezingakwazi ukuhamba kancane, ngakho-ke imitshina yamaphaneli ayisicaba amancane ayinketho efaneleke kakhulu.
Isabelomali kanye namathuba okuthuthukisa:
Izindleko zihlale zicatshangelwa ezibalulekile lapho kukhethwa noma iyiphi idivayisi yezokwelapha.Izitholi ezinkulu zamaphaneli ayisicaba ngokuvamile zibiza kakhulu, ngakho ukuhlola isabelomali sakho nokutholakala kwezimali kubalulekile.Futhi, kufanelekile ukucabangela ukuguquguquka kokuthuthukiswa okuzayo.Amanye amasistimu omtshina wamaphaneli ayisicaba ahlinzeka ngenketho yokushintsha iphaneli yomtshina ngaphakathi kweyunithi efanayo, okuvumela ukuthuthukela kuphaneli yokuxazulula enkulu noma ephakeme ngaphandle kokushintsha uhlelo lonke.
Ekuphetheni:
Ukukhetha usayizi ofanele womtshina wephaneli eyisicaba kubalulekile ukuze uthole imiphumela emihle yezithombe ekuxilongweni kwezokwelapha.Ukucatshangelwa kwesicelo somtholampilo, isixazululo, indawo yokubuka, indawo ebonakalayo, ukunethezeka kwesiguli, kanye nesabelomali kuzosiza ukuqondisa isinqumo lapho kukhethwa usayizi womtshina wephaneli eyisicaba.Ukubonisana nomkhiqizi wemishini yezokwelapha noma uchwepheshe we-radiology onesipiliyoni kuhlale kunconywa ukuze kuqinisekiswe ukukhetha okungcono kakhulu kwesidingo ngasinye sesithombe esithile.
