Ithola ikhoyili
Kuhlelo lwe-MRI, ikhoyili eyamukelayo iyingxenye ebalulekile, ethinta ngokuqondile ikhwalithi yesithombe. Amakhoyili emukelayo alomlandu wokuthola isignali ye-MR. I-oscillating net flux kazibuthe evela kusistimu yokusonta ejabulile ingabanjwa ikhoyili lapho kukhiqizwa khona amandla kagesi. Lokhu kwamanje kuyabe sekukhuliswa, kufakwe kudijithali, futhi kuhlungwe ukuze kukhishwe ulwazi lwemvamisa kanye nesigaba.
Ngemva kweminyaka eminingi yokucwaninga ngokungagodli nokusebenza kanzima, ithimba le-R&D lenkampani yethu selisungule eyalo ikhoyili yokwamukela ngokuhlolwa okuphindaphindiwe neziqhathaniso, futhi izinkomba zokusebenza kwayo sezifinyelele ezingeni eliphambili lemboni.
Sinezinhlobo eziningi zamakhoyili okwamukela esingakhetha kuzo, angahlukaniswa ngokuya ngendlela abukeka ngayo, angahlukaniswa ngamakhoyili angaphezulu, amakheji ezinyoni, namakhoyili ashintshashintshayo. Ngaphezu kwalokho, umsebenzisi angakhetha inani lamashaneli ekhoyili njengoba kudingeka,
Ngokuvamile, amakhoyili ezinyoni yiwona asetshenziswa kakhulu, futhi angasetshenziswa ekhanda, entanyeni, emadolweni, njll.; isibonelo, ikhoyili yekheji yezinyoni eneziteshi ezimbili yenziwe ngamakhoyili e-solenoid namakhoyili esihlalo. Amakhoyili ethu anezici zekhwalithi ephezulu nokufana okuhle, Angakwazi ukuhlangabezana nezidingo ezihlukahlukene zokuskena, ngesikhathi esifanayo, futhi sihlinzeka ngezinsizakalo ezenziwe ngokwezifiso, abasebenzisi bangakhetha ubukhulu ngokwabo.
Ikhoyili yangaphezulu ingasetshenziselwa ukuskena umgogodla noma ezinye izingxenye ezithakaselwayo; uma usebenzisa ikhoyili engaphezulu, ngenxa yokuvuleka kwayo, ungakwazi ukuskena indawo oyithandayo ngokuma okuhlukene.
Ikhoyili ye-transceiver wuhlobo olusha lwekhoyili. Ukudlulisa nokwamukela kwayo kuhlangene, ngakho ubukhulu bekhoyili buncane kunamakhoyili avamile. Ngaphansi kwezimo ezifanayo, uma kuqhathaniswa nesistimu ehlukanisiwe ye-transceiver, inezidingo ezincane emandleni esikhulisamandla samandla e-RF. Ngaphezu kwalokho, ngenxa yobukhulu bayo obuncane, ayidingi usayizi omkhulu wokuvula uzibuthe, futhi ingasetshenziselwa uhlelo oluncane noma ezinye izinhlelo ezinezidingo eziqinile zesikhala.
