Iingcango zeSkrini ze-MRI Umgangatho olungileyo owenziwe ngokwezifiso

Umnatha wentsimbi ufakwe kwisakhelo esikhulu somthi kwaye udityaniswe ngokuqinileyo.Ukuze kukhuselwe umphumo wokukhusela indawo, umnyango jikelele kufuneka ugqunywe ubuncinane ngamaleko amabini e-mesh yesinyithi, kwaye isithuba phakathi kweeleya ezimbini sihambelana nesithuba seminatha emibini kwigumbi lokukhusela.Ukufezekisa uqhagamshelwano oluhle kunye nokuqina, imiphetho ejikeleze umnyango wesikrini kufuneka idityaniswe ngepleyiti yentsimbi yezinto ezifanayo, kunye nephepha lokudibanisa eli-elastic eline-conductivity ephezulu ligxininiswe kwiplate yentsimbi ukuqinisekisa ukuba umnyango udibene kakuhle emva kokuvala. .Ucango kufuneka kwakhona luxhotyiswe ngeknobhu yesikrufu.

Kukho abantu abaninzi abangawuqondiyo umgaqo weminyango yesikrini, kwaye bacinga ukuba ukhuseleko lwe-electromagnetic kunye nokumisa umzimba okukhuselayo kunxulumene.Enyanisweni, kukho izinto ezimbini kuphela ezichaphazela ngokwenene ukusebenza kwekhaka: enye kukuba yonke i-shield surface kufuneka iqhube kwaye iqhubeke, kwaye enye kukuba akukho mqhubi ongena ngqo kwi-shield.Kukho iidiscontinuities ezininzi ze-conductive kwikhaka, eyona nto ibalulekileyo yi-gap engaqhubekiyo eyenziwe ekudibaneni kweendawo ezahlukeneyo zekhaka.

Enye indlela yokusombulula oku kuvuza kukugcwalisa izithuba nge-conductive elastic material, ukuphelisa amanqaku angaqhubekiyo.Kwaye le mathiriyeli yokuzalisa i-electromagnetic seal gasket.Ngokuchanekileyo, nokuba umsantsa okanye umngxuma uya kuvuza uthatyathwe kubungakanani be-electromagnetic wavelength xa kuthelekiswa nomsantsa okanye umngxuma, kwaye xa i-wavelength inkulu kunobukhulu bokuvula, ayizukuvelisa ukuvuza okucacileyo.Ukukhusela i-electromagnetic yindlela yokulawula ukuphazamiseka kwe-electromagnetic ngokusebenzisa umgaqo wokuhlukaniswa kwesinyithi, ukufakwa kunye nokusasazwa kwemitha ukusuka kwindawo ukuya kwenye.
