Ultrasound ndi zotanuka makina mafunde mu zakuthupi sing'anga.Ndi mawonekedwe ozungulira.Choncho, angagwiritsidwe ntchito kudziwa zokhudza thupi ndi pathological zambiri za thupi la munthu, ndiko kuti, matenda ultrasound.Panthawi imodzimodziyo, imakhalanso mawonekedwe a mphamvu.Pamene mlingo wina wa ultrasound propagates mu zamoyo, mwa mogwirizana, zingachititse kusintha kwa ntchito ndi dongosolo la zamoyo, ndiko kuti, akupanga kwachilengedwenso kwenikweni.
Zotsatira za ultrasound pa maselo makamaka monga matenthedwe zotsatira, cavitation zotsatira ndi makina kwenikweni.The matenthedwe zotsatira ndi kuti pamene ultrasound propagates sing'anga, ndi kukangana amalepheretsa maselo kugwedera chifukwa ndi ultrasound ndi otembenuka mbali ya mphamvu mu kutentha m'deralo (42-43 ℃).Chifukwa kutentha koopsa kwa minofu yachibadwa ndi 45.7 ℃, ndipo kukhudzidwa kwa minofu ya Liu yotupa ndipamwamba kuposa minofu yachibadwa, kagayidwe kake ka maselo otupa a Liu amawonongeka pa kutentha kumeneku, ndipo kaphatikizidwe ka DNA, RNA ndi mapuloteni amakhudzidwa. , Motero kupha maselo a khansa popanda kukhudza minofu yachibadwa.
Cavitation kwenikweni ndi mapangidwe vacuoles mu zamoyo pansi akupanga walitsa.Ndi kugwedezeka kwa ma vacuoles ndi kuphulika kwawo kwachiwawa, kukameta ubweya wa makina ndi chipwirikiti zimapangidwira, zomwe zimapangitsa kutupa kwa Liu kutuluka magazi, kuwonongeka kwa minofu ndi necrosis.
Kuonjezera apo, pamene kuwira kwa cavitation kumasweka, kumatulutsa kutentha kwakukulu (pafupifupi 5000 ℃) ndi kuthamanga kwapamwamba (mpaka 500 ℃) × 104pa), zomwe zingathe kusokoneza mpweya wa madzi kuti utulutse.OH zazikulu ndi.H atomu.The redox reaction chifukwa.OH zazikulu ndi.H atomu ingayambitse kuwonongeka kwa ma polima, kusagwira ntchito kwa enzyme, lipid peroxidation ndi kupha maselo.
