Superconducting Veterinary MRI System
Cov hlau nplaum Superconducting yog tsim los ntawm kev siv qhov tshwm sim uas cov khoom siv tiv thaiv kev ua haujlwm qis dua qis dua xoom ntawm qhov kub thiab txias. Lawv feem ntau yog ua los ntawm cov khoom siv niobium-titanium alloy thiab txias los ntawm cov kua helium (4.2K). Thaum tam sim no dhau los ntawm cov hlau nplaum, Tom Qab lub tshuab nqus hlau, tshem tawm lub zog hluav taws xob los ua qhov chaw ruaj khov thiab zoo ib yam. Cov hlau nplaum khaws cov kauj hauv qab qhov ntsuas kub los ntawm cov tub yees, thiab tsis xav tau lub zog ntxiv.
Cov hlau nplaum Superconducting tuaj yeem tsim lub zog sib nqus zoo dua qub, ua kom muaj zog sib nqus ruaj khov thiab sib nqus sib nqus zoo ib yam. Qhov no txhais tau tias cov duab zoo dua qub, teeb liab-rau-suab nrov zoo dua, sib piv thiab daws teeb meem, thiab ua kom nrawm dua.
Cov hlau nplaum zoo tshaj plaws feem ntau muaj cov qauv zoo ib yam, uas zoo li muaj peev xwm "claustrophobia" thiab tsis muaj txiaj ntsig zoo rau kws kho mob kev ua haujlwm thiab saib xyuas cov cim tsiaj hauv qab tshuaj loog. Ib qho ntxiv, vim hais tias cov hlau nplaum superconducting ib txwm muaj qhov loj dua qhov chaw sib nqus sib nqus, yuav tsum muaj thaj chaw teeb tsa loj dua.
1. Tsis muaj kua helium/kua helium tsawg dua. Tsis tas yuav xav txog kev ua kua helium poob, ua haujlwm qis thiab them nqi kho mob
2. Qhov qhib loj, sib xws nrog kev txheeb xyuas cov tsiaj loj
3. Tsis cuam tshuam thiab cuam tshuam kev cuam tshuam me me kev phais ua los ntawm cov duab sib nqus sib nqus tuaj yeem nqa tawm
4. Cov hlau nplaum yog lub teeb hauv qhov hnyav, tsis xav tau kev txhawb nqa lub zog ntxiv, thiab tuaj yeem ntsia tau rau hauv pem teb siab
1. Hom hlau nplaum: U hom
2. Lub zog hlau nplaum: 0.5T, 0.7T, 1.0T
3. Homogeneity:<10PPM 30cmDSV
