Ama-Flat Panel DetelUguqule insimu yokucabanga kwezokwelapha ngokunikeza izithombe ezisezingeni eliphakeme ngokuvezwa kwemisebe encane. Phakathi kobuchwepheshe obuhlukahlukene bokuthola umtshina,Ama-Amorphous Selenium Flat Panel Detelzivelele ngenxa yemigomo yazo yokusebenza eyingqayizivele nekhwalithi yesithombe esiphakeme.
Ama-Amorphous Selenium Flat Panel Detectors asebenzisa ungqimba omncane we-amorphous Selenium njengezinto ze-photokoductive. Lapho ama-x-ray edlula esigulini futhi afinyelela umtshina, amunwa yiletha le-selenium, adala ngababili umgodi we-elektroni. Lezi zithwali ezikhokhisiwe zibe zidonswa ku-electrodes ezitholakala phezulu nangaphansi komtshina, zidala isibonakaliso sikagesi esilingana namandla we-X-ray.
Enye yezinzuzo ezisemqoka ze-Amorphous Selenium Detenictors ukuguqulwa kwazo okuqondile kwama-X-ray kuzimpawu zikagesi. Le nqubo yokuguqulwa eqondile iqeda isidingo se-Scintillators noma ezinye izinto eziphakathi, eziholela ekuxazululeni okuphezulu kwendawo kanye nekhwalithi yesithombe ethuthukisiwe. Ngaphezu kwalokho, inombolo ephezulu ye-atomic ye-amomium ye-amomium ye-amomium ikwenza kube yi-abrorber esebenza kahle yama-X-ray, athuthukise futhi ukuzwela komtshina.
Uma kungekho emkhakheni kagesi, ama-elektroni ambole ngamehlo e-amorphous Selenisium avame ukubuyisa, okuholela ekubodisweni kwesiginali nokulahleka kwekhwalithi yesithombe. Ukuvimbela lokhu, ama-amorphous Selenium Detoctors afakwe i-Bias Voltage eyakha inkambu kagesi, ukuhlukanisa abathwali abakhokhiswayo futhi abavumele ukuba bafinyelele kuma-electroDode ngaphandle kokuphinda basebenze.
Amandla ka-Bias Voltage, imvamisa ebangeni lama-5-10 KV, asetshenziswa ku-electrodes ngesikhathi sokutholwa kwesithombe, aqinisekise ukuthi insimu kagesi ihlala isekhona ukugcina ubuqotho besiginali. Le nqubo yokuqoqa okuqhubekayo kusiza ukutholwa kwesithombe esisheshayo, okwenza ama-amorphous Selenium Detectors alungele izinhlelo zokusebenza zesikhathi sangempela ezifana nezinqubo eziguqulwayo nezinqubo ezihlangene.
Ngaphezu kwalokho, imvelo eqinile ye-Selenium eqinile futhi eqinile ivumela ukuthembeka kwesikhathi eside kanye nezidingo zokulungiswa okuncane, okwenza kube yikhethelo elihle lezinhlelo zokucabanga zezokwelapha. Ukuguqulwa okuqondile kanye namakhono we-Signal Amplification we-Amorphous Selenium Detectors aphumela kumsindo ophansi kanye nokusebenza okuphezulu kwe-Detector Quantum (DQE), okufaka isandla ekufanisweni okuhle kwesithombe nokubonakala kwemininingwane ye-anatomical.
Ngaphezu kwemicabango yezokwelapha, abatholayo abahlaseli be-Amorphous Balenium Flat Panel bathole izicelo ekuhlolweni nasekuhlolweni kokuphepha kwezimboni ngenxa yezimpawu zabo zokusebenza okuphezulu. Amandla abo okukhiqiza ukulungiswa okuphezulu, izithombe zomsindo ophansi ngesikhathi sangempela zibenza babe ngamathuluzi agxile ezinhlobonhlobo zezimo zokucabanga.
Njengoba ubuchwepheshe buqhubeka buqhubekisa phambili, kungenzeka ukuthi kwenziwe ngcono ukuthuthuka ku-Amorphous Selenium Flat Panel Detels kukhulu. Ukucwaninga okuqhubekayo kuhlose ukuthuthukisa ukusebenza kwawo ngokwenza kahle izindlela zokutheleka, kucwengezelwa ukwakheka kwama-elektrodi, kanye nokuhlola izinto ezintsha zesakhiwo somtshina.
Sekukonke, umgomo osebenzayo we-Amorphous Selenium Flat Panel Detanictors, ehambisana nekhwalithi yazo ehlukile yesithombe nokwethembeka, ugcizelela ukubaluleka kwawo ekuthuthukiseni inkambu yezokwelapha nangale kwalokho. Njengokufunwa kwezixazululo ezisezingeni eliphakeme, izixazululo ze-low-dose yokucabanga ziyaqhubeka nokukhula, abakwa-Amorphous Selenium Detoctors balungele ukudlala indima ebaluleke kakhulu ekubumbeni ikusasa le-radiology kanye nesayensi yokucabanga.
