Ultrasound is an elastic mechanical wave in material medium. Icho chimiro chewave. Nokudaro, inogona kushandiswa kuona ruzivo rwehutano uye pathological yemuviri womunhu, kureva, diagnostic ultrasound. Panguva imwecheteyo, ihwowo chimiro chesimba. Kana imwe dosi ye ultrasound ichipararira muzvisikwa, kuburikidza nekudyidzana kwavo, inogona kukonzera shanduko mukushanda uye chimiro chezvipenyu, kureva, ultrasonic biological effect.

Migumisiro ye ultrasound pamasero inonyanya kusanganisira thermal effect, cavitation effect uye mechanical effect. Mhedzisiro yekupisa ndeyekuti kana ultrasound ichipararira mukati, kukwesha kunotadzisa kuzunguzika kwema molecular kunokonzerwa ne ultrasound uye inoshandura chikamu chesimba mukupisa kwakanyanya kwenzvimbo (42-43 ℃). Nekuda kwekuti tembiricha inouraya yakajairika i45.7 ℃, uye kunzwa kwekuzvimba kweLiu tissue kwakakwira kupfuura kuya kwenyama yakajairwa, mametabolism emasero eLiu akazvimba anokanganiswa nekupisa uku, uye kuumbwa kweDNA, RNA neprotein kunokanganisa, Saka kuuraya maseru egomarara pasina kukanganisa matishu akajairwa.

Cavitation effect ndiko kuumbwa kwevacuoles muzvisikwa pasi pe ultrasonic irradiation. Nekuzunguzika kwema vacuoles uye kuputika kwavo kwechisimba, mechanical shear pressure uye mhirizhonga zvinogadzirwa, zvichikonzera kuzvimba Liu kubuda ropa, kuparara kwetishu uye necrosis.

Pamusoro pezvo, kana bubble recavitation ratsemuka, rinoburitsa tembiricha yakakwira nekukurumidza (inenge 5000 ℃) uye yakanyanya kudzvanywa (kusvika 500 ℃) × 104pa), iyo inogona kuparadzanisa mhute yemvura kuburitsa. OH radical uye. H atomu. Iyo redox reaction yakakonzerwa ne. OH radical uye. H atomu inogona kutungamirira mukuora kwepolymer, enzyme inactivation, lipid peroxidation uye kuuraya masero.
