Ultrasound yog ib hom kev vibrational yoj.Nws tuaj yeem kis tsis zoo los ntawm cov ntaub so ntswg nyob, thiab qhov no ua rau nws tuaj yeem siv cov khoom siv ntxiv ntawm ultrasound rau kev kho mob.Yog hais tias ultrasound beams tsom thiab txaus ultrasonic zog yog concentrated nyob rau hauv ntim thaum lawv propagate los ntawm cov ntaub so ntswg, qhov kub thiab txias nyob rau hauv lub focal cheeb tsam tej zaum yuav raug nce mus rau theem ntawm cov qog nqaij hlav, ua rau cov ntaub so ntswg ablation.Cov txheej txheem no tshwm sim yam tsis muaj kev puas tsuaj rau cov ntaub so ntswg los yog overlying, thiab cov ntaub so ntswg ablation txheej txheem uas ua hauj lwm cov kab teeb yog paub interchangeably raws li siab siv tsom ultrasound (HIFU).
HIFU tau siv los ua ib qho ntxiv rau kev kho hluav taws xob thiab tshuaj khomob rau kev kho mob qog noj ntshav txij li xyoo 1980s.Lub hom phiaj ntawm hyperthermia kom nce qhov kub ntawm cov qog los ntawm 37 ℃ mus rau 42-45 ℃, thiab kom tswj tau qhov kub thiab txias faib rau hauv qhov nqaim kho ntau li 60 feeb.
