Tomsic piav qhia tias MRIs tam sim no siv niobium titanium superconductors uas tau txias hauv da dej ntawm cov kua heliumCov kua helium pab tiv thaiv cov hlau nplaum quenches qhov twg cov hlau nplaum nce hauv qhov kub vim qhov cua sov hauv zos. thiab tuaj yeem ua rau puas tsuaj. Qee lub tshuab MRI tau ntsib qhov teeb meem ntau dua li lwm tus.
Vim li cas superconducting hlau nplaum siv hauv MRI?
Superconductive MRI cov hlau nplaum siv lub voj voog solenoid ua los ntawm cov hlau xws li niobium / titanium lossis niobium / tin puag ncig ntawm tooj liab. Cov alloys no muaj qhov khoom ntawm xoom tsis kam rau hluav taws xob tam sim no thaum txias rau txog 10 kelvin. Lub kauj yog khaws cia hauv qab no nrog cov kua helium.
Yuav siv cov superconductors li cas?
Cov khoom siv superconducting tau siv sim ua kom nrawm kev sib txuas ntawm lub computer chips, thiab cov coils superconducting ua tau cov hluav taws xob muaj zog heev ntawm kev ua haujlwm hauv qee qhov kev sib nqus resonance imaging (MRI) cov kws kho mob siv cov tshuab los tshuaj xyuas cov ntaub so ntswg hauv lawv cov neeg mob.
Vim li cas feem ntau MRI cov tshuab ua haujlwm zoo tshaj?
MRI feem ntau siv cov hlau nplaum superconducting. Lub ntsiab kom zoo dua yog tias cov hlau nplaum superconducting muaj peev xwm ua kom muaj zog thiab ruaj khov hlau nplaum ntau dua li ob hom (tiv taus thiab ruaj khov) suav nrog hauv qab no.
MRI superconductors yog dab tsi?
Cov khoom siv hluav taws xob ntawm cov hlau nplaum tam sim no feem ntau yog tsim los ntawm niobium-titanium. Cov khoom no muaj qhov kub thiab txias ntawm 10 kelvins thiab muaj peev xwm ua tau superconduct txog li 15 teslas.
