Inkqubo ye-MRI yezilwanyana
Iimagnethi ezihamba phambili zenziwa ngokusebenzisa imeko yokuba ukumelana nezinto ezihamba kakhulu kuncipha ukuya kwiqondo lobushushu elithile. Zihlala zenziwe ngezinto ze-niobium-titanium alloy kwaye zipholile yi-helium engamanzi (4.2K). Xa okwangoku kudlula kwikhoyili yemagnethi, emva kwentsimi yamandla ombane, cima umbane ukuze wenze umhlaba ozinzileyo nofanayo. Imagnethi igcina ikhoyili ingezantsi kobushushu obubalulekileyo kwifriji, kwaye akukho sibonelelo songezelelweyo sombane siyafuneka.
Iimagnethi ezihamba phambili zinokuvelisa amandla aphezulu emagnethi, uzinzo olungcono lwentsimi kunye nokufana kwentsimi yamagneti. Oku kuthetha ukuba ubunjani bomfanekiso ongcono, umyinge ongcono wokuya kwisandi, umahluko kunye nesisombululo, kunye nesantya sokucinga ngokukhawuleza.
Oomazibuthe abaqhelekileyo abenza imithambo ngokubanzi banesakhiwo esimile njengomgqomo, esidla ngokubakho "kwi-claustrophobia" kwaye ayihambelani nokusebenza koogqirha kunye nokuqwalaselwa kweempawu zezilwanyana phantsi kweanesthesia. Ukongeza, ngenxa yokuba umazibuthe oqhelekileyo wokuthwala umthwalo une-magnetic field ephambukayo enkulu, indawo enkulu yokufaka isixhobo iyafuneka.
1. Akukho helium engamanzi / i-helium engamanzi engaphantsi. Akukho sidingo sokujonga ilahleko ye-helium engamanzi, ukusebenza okuphantsi kunye neendleko zokugcina
2. Ukuvula okukhulu, okuhambelana nokuskena kwezilwanyana zasekhaya ezinkulu
3. Ungenelelo olungenelelayo kunye nongenelelo olungenelelo oluncinci olukhokelwa yimifanekiso yamagnetic resonance lunokwenziwa
4. Imagnethi ilula ngokobunzima, akukho mfuneko yokuqiniswa kokuthwala umthwalo, kwaye inokufakwa kwimigangatho ephezulu
1. Uhlobo Magnet: U uhlobo
2.Magnet amandla endle: 0.5T, 0.7T, 1.0T
3. Ubungqingili:<10PPM 30cmDSV
