Ukufumana iCoil
Kwinkqubo yeMRI, iikhoyili yokufumana yinto ebalulekileyo, echaphazela ngokuthe ngqo umgangatho womfanekiso. Fumana iikhoyili zinoxanduva lokufumana isignali ye-MR. Umjelo oshukumisayo womnatha oshukumayo ovela kwinkqubo yokujikeleza okuchwayitisayo unokufakwa kwikhoyili apho kuveliswa khona amandla ombane. Le yangoku iyandiswa, ifakwe kwikhompyutha, kwaye ihluzwe ukukhupha ulwazi rhoqo kunye nakwisigaba.
Emva kweminyaka yophando olungagungqiyo kunye nokusebenza nzima, iqela lenkampani ye-R & D liphuhlise eyayo i-coil yokufumana ngokusebenzisa iimvavanyo ezahlukeneyo eziphindaphindiweyo kunye nothelekiso, kwaye izikhombisi zayo zokusebenza ziye zafikelela kwinqanaba eliphambili kushishino.
Sineentlobo ezininzi zokufumana iikhoyili onokukhetha kuzo, ezinokuhlelwa ngokwendlela ezibonakala ngayo, ezinokwahlulwa zibe ngumphezulu, intaka yeentaka, kunye neekhoyili ze-transceiver. Ukongeza, umsebenzisi unokukhetha inani lamajelo ekhoyili njengoko kufuneka,
Ngokubanzi, iikhoyili zentaka zezona zisetyenziswa kakhulu, kwaye zinokusetyenziswa entloko, entanyeni, emadolweni, njl .; umzekelo, imijelo emibini yeentaka ezinentaka yenziwe ngeeoyile ze-solenoid kunye neekhoyili zesali. Iikhoyili zethu zinemigangatho ekumgangatho ophezulu kunye nokufana okuhle, Ngaba zinokuhlangabezana neemfuno ezahlukeneyo zokuskena, kwangaxeshanye, sikwanikezela ngeenkonzo ezenzelwe wena, abasebenzisi banokukhetha ubungakanani ngokwabo.
Ikhoyili yomphezulu ingasetyenziselwa ukuskena umqolo okanye ezinye izinto ezinomdla; xa usebenzisa i-coil yomphezulu, ngenxa yokuvuleka kwayo, unokukroba indawo yomdla kwiindawo ezahlukeneyo zokuma.
Ikhoyili ye-transceiver luhlobo olutsha lwekhoyili. Ukuhambisa kunye nokufumana kwayo kudityanisiwe, ke ubungakanani bekhoyili bincinci kuneekhoyili eziqhelekileyo. Ngaphantsi kweemeko ezifanayo, xa kuthelekiswa nenkqubo eyahlukileyo ye-transceiver system, ineemfuno ezincinci kumandla esikhulisi samandla seRF. Ukongeza, ngenxa yobukhulu bayo obuncinci, ayifuni ubungakanani bemagnethi enkulu yokuvula, kwaye inokusetyenziselwa inkqubo encinci okanye ezinye iinkqubo ezineemfuno ezingqongqo zesithuba.
