Taw qhia:
THI (Tissue Harmonic Imaging) yog cov txheej txheem ultrasound siab tshaj plaws uas tau hloov kho kev kuaj mob. Los ntawm kev siv cov kev sib haum xeeb tsim tawm hauv cov ntaub so ntswg, THI muab cov kev daws teeb meem siab, cov duab ntxaws ntxaws uas ua rau cov kws kho mob tau txais kev kuaj mob kom raug. Kab lus no yog npaj los muab cov ntsiab lus ntawm THI, nws cov hauv paus ntsiab lus, cov txiaj ntsig, thiab kev siv hauv kev kho mob.
Principles of THI:
THI yog raws li lub hauv paus ntsiab lus ntawm harmonic imaging, uas muaj xws li kis tau tus mob thiab txais tos ntawm ultrasound nthwv dej ntawm ntau zaus dua li cov pa ultrasound. Kev kuaj ultrasound ib txwm tso siab rau qhov tseem ceeb ntawm cov nthwv dej sib kis, uas tuaj yeem raug cuam tshuam thiab cuam tshuam los ntawm ntau yam. Nyob rau hauv sib piv, THI xaiv captures harmonic frequencies tsim nyob rau hauv cov ntaub so ntswg, uas ua rau superior duab zoo thiab txo artifacts.
Cov txiaj ntsig ntawm THI:
Txhim kho cov duab daws teeb meem: THI tsim cov duab nrog txhim kho qhov kev daws teeb meem thiab cov ntaub so ntswg sib txawv piv rau cov pa ultrasound. Qhov no tso cai rau kom pom kev zoo dua ntawm cov qauv anatomical, cov kab mob me me, thiab cov ntsiab lus zoo, ua rau kev txhim kho qhov tseeb.
Txo Cov Artifacts: THI txo qis cov khoom qub, xws li clutters thiab side-lobe artifacts, uas tej zaum yuav tsis pom cov ntsiab lus tseem ceeb hauv cov duab ultrasound. Cov teeb liab sib haum xeeb tsim los ntawm cov ntaub so ntswg tsis tshua muaj kev cuam tshuam los ntawm lub suab nrov thiab cuam tshuam, ua rau cov duab huv thiab txhim khu kev qha.
Enhanced Penetration: THI tuaj yeem nkag mus tob rau hauv cov ntaub so ntswg piv rau cov pa ultrasound. Qhov txiaj ntsig no tshwj xeeb yog qhov zoo tshaj plaws hauv kev txheeb xyuas cov neeg mob rog lossis cov neeg muaj lub cev sib sib zog nqus, vim nws muab kev pom zoo ntawm cov qauv uas yav dhau los nyuaj rau kev ntsuas.
Ntxiv qhov sib txawv: THI txhim kho qhov sib txawv ntawm cov ntaub so ntswg sib txawv, ua kom yooj yim rau kev sib txawv ntawm cov qauv ib txwm muaj thiab cov kab mob pathological. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev ntsuam xyuas cov kab mob vascular, qog, thiab ntsuas cov ntshav ntws, vim tias nws ua rau muaj txiaj ntsig zoo ntawm kev txawv txav.
Applications of TSI:
Abdominal Imaging: THI yog siv dav rau kev kuaj mob plab, nrog rau daim siab, lub raum, tus po, thiab kev ntsuam xyuas pancreas. Nws pab txhawm rau txheeb xyuas qhov mob, ntsuas lub cev morphology, thiab ntsuas cov ntshav ntws hauv cov qauv no.
Cardiac Imaging: THI tau ua pov thawj tias muaj txiaj ntsig hauv kev kuaj mob plawv, ua kom muaj kev soj ntsuam ntxaws ntxaws ntawm cov hlab plawv, li qub, thiab myocardial muaj nuj nqi. Nws pab txhawm rau txheeb xyuas ntau yam mob plawv, xws li valvular abnormalities, myocardial infarction, thiab congenital heart defects.
Vascular Imaging: THI ua lub luag haujlwm tseem ceeb hauv kev ntsuas cov hlab ntsha, suav nrog cov hlab ntsha carotid, cov hlab ntsha peripheral, thiab cov hlab ntsha. Nws pab kuaj cov kab mob vascular, txheeb xyuas stenosis lossis occlusions, thiab ntsuas cov qauv ntshav.
Obstetric thiab Gynecological Imaging: THI tau siv ntau ntxiv hauv kev kuaj obstetric thiab gynecological los soj ntsuam kev loj hlob ntawm tus menyuam hauv plab, kuaj pom qhov txawv txav, thiab ntsuas tus poj niam cev xeeb tub. Nws muab cov duab ntxaws ntxaws rau kev kuaj mob ua ntej yug menyuam thiab saib xyuas kev xeeb tub.
Xaus:
THI ultrasound imaging tau hloov kho kev kuaj mob los ntawm kev muab cov duab siab, tsis muaj duab kos nrog cov ntaub so ntswg zoo dua. Nws cov txiaj ntsig suav nrog txhim kho cov duab daws teeb meem, txo cov khoom qub, nce nkag mus, thiab txhim kho qhov sib txawv. Nrog rau cov ntawv thov thoob plaws ntau yam kev kho mob tshwj xeeb, THI tau dhau los ua cov cuab yeej tseem ceeb rau cov kws kho mob, ua kom muaj kev kuaj mob kom raug thiab txhim kho kev saib xyuas neeg mob.
