Umehluko phakathiUkuqina kwesithombena-Ama-Flat Panel Detel.In emkhakheni weukucabanga kwezokwelapha, Ama-X-ray adlala indima ebalulekile ekuhlolweni nasekwelapheni izifo ezahlukahlukene nokulimala. Intuthuko kwezobuchwepheshe iholele ekuthuthukisweni kwemishini yokuthwebula isithombe esinezinhlaka ze-X-ray. Izinto ezimbili ezinjalo ezintsha zingukuqina kwezithombe kanye nokuthola iphaneli. Yize zombili zenzelwe ukuthuthukisa izithombe ze-X-ray, kunomehluko omkhulu phakathi kobuchwepheshe bobabili.
Ukuze uqonde umehluko, ake siqale ngokuqina kwesithombe. Ama-Image Ansifiers amadivayisi we-electro-optical asetshenziswa kakhulu emkhakheni we-radiology. Umsebenzi wabo oyinhloko ukuthuthukisa izithombe ze-X-ray, ukuzenza zibonakale zikhanya futhi zinemininingwane eminingi. Umgomo osebenzayo wokuqina kwesithombe ukuguqula izithombe ze-X-ray zibe ngama-Photon abonakalayo akhanyayo, khulisa ubukhulu besithombe se-X-ray sokuqala.
Ingxenye esemqoka yesithombe sokuqina kwesithombe yi-phosphor yokufaka, emuncaba izithombe ze-X-ray futhi zikhipha ama-Photon abonakalayo. Lezi zithombe zisheshiswa futhi zigxile kwi-phosphor ekhiphayo, zidale isithombe esikhulisiwe. Lesi sithombe esikhulisiwe singase sithunjwe yikhamera noma sikhonjiswe kumqaphi ngezinjongo zokuxilonga. Izilungiselelo zezithombe zisebenza kahle kakhulu ekuhlinzekeni izithombe zesikhathi sangempela futhi zilungele izinqubo ezidinga ukucabanga kwesikhathi sangempela, njenge-fluoroscopy.
Ama-Flat Panel Detectors (FPDs) aphenduke enye indlela yokuqina kwesithombe. Ama-Flat Panel Detoctors angamadivayisi aqinile abonisa izithombe ngokuqondile athwebula izithombe ze-X-ray bese uziguqula zibe yizimpawu zedijithali. Ngokungafani nama-Image Ansifiaiers, ama-FPD awathembeli ekuguquleni izithombe ze-X-ray zibe ngama-Photon akhanyayo. Babesebenzisa uhlu lwama-transistors amancane wefilimu (TFTS) ukuguqula izithombe ze-X-ray zibe amasiginali kagesi.
Inzuzo eyinhloko ye-Flat Panel Detectors yikhono lokuthwebula izithombe eziphezulu zedijithali ngokuqhathanisa okuthuthukile kanye nobubanzi obunamandla. Lezi zimpawu zedijithali zingacutshungulwa ngqo futhi ziboniswe kwikhompyutha ukuze ihlaziywe ngokushesha. Ama-Flat Panel Detectors anikela ngenkundla enkulu yokubuka nokusebenza okuphezulu kwenani eliphakeme (DQE) ngokuqhathaniswa nokuqina kwesithombe, okuholela kwikhwalithi yesithombe ethuthukisiwe.
Ama-Flat Panel Detectors anikela ngezinzuzo ezibalulekile ekuguqulekeni nasekuhlukahlukene. Zingahlanganiswa kalula ezinhlelweni ze-X-ray ezikhona, zifaka esikhundleni sokuqina kwesithombe sendabuko ngaphandle kokuguqulwa okubanzi.
Umehluko phakathiI-X-ray image ukuqinaFuthi abatholi bephaneli abasesicaba balele ebukhwini babo nokusebenza kwabo. Ukuqiniswa kwesithombe ukukhulisa izithombe ze-X-ray ngokuguqula izithombe ze-X-ray zibe ngama-Photon abonakalayo akhanyayo, ngenkathi ama-Flat Panel Detoctors athwebula kahle izithombe ze-X-ray bese uziguqula zibe yizimpawu zedijithali. Zombili lezi zinqubo zinezinzuzo zazo nokubi, nokukhetha phakathi kwazo kuya ngezidingo ezithile zokucabanga, ukucatshangelwa kwezindleko, kanye nezinga lekhwalithi yesithombe edingekayo. Zombili lezi zithombe zokuqinisekiswa kanye nama-flat-panel zokuthola usizo zisiza ukuthuthukisa inkambu ye-x-ray imaging futhi uthuthukise ukunakekelwa kweziguli.
