Contrast-enhanced Ultrasound Technique For Piercing Needle

Ntxiv rau qhov sib piv cov duab sib piv, kuj tseem muaj qhov sib txawv ntawm cov duab ultrasound, lub zog sib piv kev sib haum xeeb, rov qab pulse harmonic imaging, stimulated acoustic emission imaging, low mechanical index imaging, contrast agent burst imaging thiab lwm txoj kev. Txawm hais tias siv txoj kev twg los xij, ib qho khoom siv ultrasound uas muaj peev xwm ntawm angiography yuav tsum muaj bandwidth txaus, muaj peev xwm ua haujlwm siab, thiab muaj peev xwm muab qhov tsis txaus, xws li: lub sijhawm ntsuas, MI suab siv, thiab lub sijhawm ua haujlwm ntawm lub hard disk cia.

1) Contrast agent puncture needle breaking imaging method Thaum thawj tiam ntawm kev sib piv tus neeg sawv cev yog siv, nyob rau hauv thiaj li yuav soj ntsuam cov ntaub ntawv ntawm kev sib piv tus neeg sawv cev nyob rau hauv cov hlab ntsha thiab lub cev thiab cov ntaub so ntswg, txoj kev ntawm bursting microbubbles feem ntau yog siv kom tau nplua nuj harmonics. Cov duab ntawm myocardial perfusion tuaj yeem tau txais los ntawm qhov sib piv sib piv nrog cov duab yoj lub plawv. Thaum nws los txog rau hauv plab hnyuv xws li daim siab, phau ntawv txhais tau siv kom tau txais lub sijhawm-theem duab ntawm qog perfusion nrog tus neeg sawv cev sib txawv.

2) Tsis tshua muaj neeg kho tshuab index imaging Thaum ib tug emitted ultrasound siv thiab nws mechanical index MI yog qis dua 0.15, nws yog hu ua low mechanical index. Kev yees duab nrog lub zog ultrasonic no qis dua lub zog uas lub microbubble tawg yog hu ua low-mechanical index imaging. Txoj kev no tuaj yeem paub qhov kev sib raug zoo txuas ntxiv ntawm cov ntshav ntws thiab txo qhov cuam tshuam ntawm cov nqaij mos harmonics. Cov txheej txheem siv tus neeg saib xyuas qhov sib txawv thib ob.
