Ultrasoundke mofuta oa leqhubu la elastic mechanical medium. Ke sebopeho sa maqhubu. Ka hona, e ka sebelisoa ho bona tlhahisoleseling ea fisioloji le ea pathological ea 'mele oa motho, ke hore, tlhahlobo ea ultrasound. Ka nako e ts'oanang, e boetse ke mofuta oa matla. Ha tekanyo e itseng ea ultrasound e ata ka har'a lintho tse phelang, ka ho sebelisana ha tsona, e ka baka liphetoho mosebetsing le sebopeho sa lintho tse phelang, ke hore, ultrasonic biological effect.

Liphello tsa ultrasound liseleng haholo-holo li kenyelletsa phello ea mocheso, phello ea cavitation le phello ea mechine. Phello ea mocheso ke hore ha ultrasound e hasana bohareng, khohlano e sitisa ho sisinyeha ha molek'hule e bakoang ke ultrasound le ho fetola karolo ea matla hore e be mocheso o phahameng oa sebaka (42-43 ℃). Hobane mocheso o kotsi o bolaeang oa lisele tse tloaelehileng ke 45.7 ℃, 'me kutloisiso ea lisele tsa Liu e ruruhileng e phahame ho feta ea lisele tse tloaelehileng, metabolism ea lisele tsa Liu tse ruruhileng e senyeha ka mocheso ona,' me motsoako oa DNA, RNA le protheine lia ameha, kahoo li bolaea lisele tsa kankere ntle le ho ama lisele tse tloaelehileng.

Phello ea cavitation ke hore tlas'a mahlaseli a mahlaseli a kotsi, li-vacuoles li thehoa linthong tse phelang. Ka ho thothomela ha li-vacuoles le ho phatloha ho matla ha tsona, ho hlahisoa khatello ea ho kuta le moferefere, e leng ho etsang hore Liu a ruruhe mali, ho qhalana ha lisele le necrosis.

Ho phaella moo, ha bubble ea cavitation e robeha, e hlahisa mocheso o phahameng hang-hang (hoo e ka bang 5000 ℃) le khatello e phahameng (ho fihlela ho 500 ℃) × 104pa), e ka hlahisoang ke ho arohana ha mocheso oa mouoane oa metsi OH radical le H atom, ka OH radical le The redox enzyme e ka lebisa ho Hmer atomtiation reaction, e ka lebisang ho Hmer atomtiation reaction. lipid peroxidation le ho bolaea lisele.
