Kev paub point

 Kev kho mob ultrasound (tseem hu ua diagnostic sonography lossis ultrasonography) yog cov txheej txheem kuaj mob, lossis kev siv tshuaj kho mob ntawm ultrasound. Nws yog siv los tsim cov duab ntawm cov qauv hauv lub cev xws li cov leeg, cov leeg, cov pob qij txha, cov hlab ntsha, thiab cov kabmob sab hauv. Nws lub hom phiaj yog feem ntau nrhiav ib qhov chaw ntawm tus kab mob los yog kom tshem tawm pathology. Kev coj ua ntawm kev kuaj xyuas cov poj niam cev xeeb tub siv ultrasound yog hu ua obstetric ultrasound, thiab yog ib qho kev txhim kho thaum ntxov thiab kev siv tshuaj kho mob ultrasound.

Ultrasound yog lub suab tsis muaj zaus uas siab dua li cov neeg mloog tau (> 20,000 Hz). Ultrasonic dluab, tseem hu ua sonograms, yog tsim los ntawm kev xa cov pulses ntawm ultrasound rau hauv cov ntaub so ntswg siv lub sojntsuam. Lub ultrasound pulses echo tawm cov ntaub so ntswg nrog cov khoom sib txawv thiab raug kaw thiab tso tawm ua ib daim duab.

Ntau hom duab sib txawv tuaj yeem tsim. Qhov ntau tshaj plaws yog B-hom duab (Brightness), uas qhia txog acoustic impedance ntawm ob-dimensional cross-section ntawm cov ntaub so ntswg. Lwm hom tuaj yeem pom cov ntshav ntws, kev txav ntawm cov ntaub so ntswg thaum lub sijhawm, qhov chaw ntawm cov ntshav, muaj cov molecules tshwj xeeb, qhov tawv nqaij ntawm cov ntaub so ntswg, lossis lub cev nqaij daim tawv ntawm thaj tsam peb sab.

Piv nrog rau lwm yam tseem ceeb ntawm kev kuaj mob, ultrasound muaj ntau yam zoo. Nws muab cov duab hauv lub sijhawm tiag tiag thiab tuaj yeem nqa tau thiab tuaj yeem nqa mus rau lub txaj. Nws yog tus nqi qis dua li lwm cov qauv kev ntsuas thiab tsis siv cov hluav taws xob ionizing teeb meem. Drawbacks suav nrog ntau yam kev txwv ntawm nws qhov kev pom, xws li kev xav tau rau kev sib koom tes ntawm tus neeg mob, kev vam khom ntawm lub cev, kev teeb tsa kev teeb tsa tom qab pob txha thiab huab cua lossis roj av, thiab qhov tsim nyog ntawm tus neeg ua haujlwm txawj, feem ntau yog cov kws tshaj lij.
