Ultrasound ndi mtundu wa 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 mtundu wa 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 tingati pansi akupanga walitsa, vacuoles amapangidwa mu zamoyo.Ndi kugwedezeka kwa ma vacuoles ndi kuphulika kwawo kwachiwawa, kukameta ubweya wamakina ndi chipwirikiti zimapangidwira, zomwe zimapangitsa kutupa kwa Liu kutuluka magazi, kupasuka kwa minofu ndi necrosis.

Kuphatikiza apo, kuwira kwa cavitation kukasweka, kumatulutsa kutentha kwakanthawi kochepa (pafupifupi 5000 ℃) ndi kuthamanga kwambiri (mpaka 500 ℃) × 104pa), komwe kumatha kupangidwa ndi kusungunuka kwamadzi kwa nthunzi wamadzi OH radical ndi H atomu, ndi OH. radical and The redox reaction chifukwa cha H atomu imatha kupangitsa kuwonongeka kwa polima, kusagwira ntchito kwa enzyme, lipid peroxidation ndi kupha maselo.
