Sib nqus resonance imaging system yog cov cuab yeej siv tshuaj ntsuam xyuas qhov tseeb, uas muaj cov kev xav tau siab dua rau qhov chaw teeb tsa. NMR teeb liab yog lub teeb liab tsis muaj zog heev, uas yooj yim cuam tshuam los ntawm kev cuam tshuam sab nraud. Yog li, MRI systems feem ntau yuav tsum tau nruab nrog Faraday tawb (RF shielding chav) kom cais tawm sab nraud xov tooj cua zaus cuam tshuam los ntawm kev nkag mus rau hauv lub cev. Txawm li cas los xij, cov chav MRI tsis siv lossis xav tau cov x-ray lossis hluav taws xob tiv thaiv vim lawv tsis tsim cov ionizing x-ray lossis gamma tawg.

CSJ muaj qhov ua tiav qhov chaw sib nqus resonance qhov chaw daws teeb meem, pib los ntawm qhov chaw tshawb fawb thiab kev npaj tsim, mus rau kev tsim khoom thiab kev ua haujlwm, thiab tom qab ntawd kev teeb tsa ntawm qhov chaw thaiv cov chav, thaiv qhov rooj, thaiv qhov rais soj ntsuam, lim phaj, teeb pom kev zoo, thiab lwm yam.

Tom qab RF shielding raug teeb tsa, nws yuav tsum tau kuaj xyuas kom ntseeg tau tias RF suab nrov tsawg hauv ib puag ncig ntawm MRI cov cuab yeej. Feem ntau, txhawm rau kuaj RF suab nrov, lub tshuab xa hluav taws xob tau muab tso rau sab nraud ntawm chav tsev uas yuav kis tau qee zaus thiab lub zog ntawm RF yoj. Lub receiver yog muab tso rau hauv lub shielded chav los txiav txim siab npaum li cas ntawm cov teeb liab nkag mus rau RF shielding.

Thaum kawg, cov txheej txheem ua tiav tau ua tiav zoo rau kev kho kom zoo nkauj sab hauv thiab tu.
