Ultrasonic transducer yog ib qho khoom siv uas hloov hluav taws xob rau hauv lub zog ultrasonic.Hauv kev lag luam kev kho mob, ultrasonic transducers tau dav siv hauv thaj chaw xws li kev kuaj ultrasonic, kev kho ultrasonic, thiab kev phais ultrasonic, thiab kev tsim kho tshiab thiab kev txhim kho tas li tau ua thaum lub sijhawm thov txheej txheem.
Daim ntawv thov ntawm ultrasonic transducers hauv kev kuaj ultrasonic yog qhov ntau.Los ntawm cov nthwv dej ultrasonic tawm los ntawm ultrasonic transducer thiab cov nthwv dej uas tau txais, cov kws kho mob tuaj yeem tau txais cov ntaub ntawv duab hauv tib neeg lub cev.Qhov no tsis-tsis muaj kev soj ntsuam tsis tuaj yeem siv los kuaj pom morphology thiab ua haujlwm ntawm cov plab hnyuv siab raum thiab ua haujlwm ntawm cov morphology, tab sis kuj tseem yuav txiav txim siab ntawm cov qog thiab ntsuas qhov kev pheej hmoo ntawm cov kab mob plawv.Raws li kev siv thev naus laus zis, kev daws teeb meem thiab rhiab heev ntawm ultrasound transducers tau zoo heev, ua rau cov kws kho mob kuaj cov kab mob kom raug.
Hauv kev phais ultrasound, ultrasound transducers yog siv los txiav thiab coagulate cov ntaub so ntswg.Lub ultrasonic transducer generates mechanical zog los ntawm high-frequency kev co, uas yuav raug txiav cov ntaub so ntswg yam tsis ua puas ib ncig ntawm cov hlab ntsha thiab paj hlwb.Txoj kev phais no yog qhov tseeb dua thiab ua rau lub sijhawm rov qab ua haujlwm luv dua.
Tsis tas li ntawd, ultrasonic transducers kuj tseem siv tau los kho qhov txhab, nres los ntshav, thiab txhawb kev kho qhov txhab.Ntxiv rau cov ntawv thov saum toj no, ultrasonic transducers kuj muaj qee qhov kev siv tshiab.Piv txwv li, kev phais mob qog nqaij hlav me me tau tshwm sim nyob rau xyoo tas los no, siv cov txheej txheem percutaneous lossis endoscopic ua ke nrog ultrasound transducers.Txoj kev phais no muaj qhov zoo ntawm kev raug mob tsawg dua thiab rov qab sai dua, uas tuaj yeem txo tus neeg mob qhov mob thiab kev pheej hmoo ntawm kev phais.Tsis tas li ntawd, ultrasound transducers tuaj yeem ua ke nrog lwm yam kev yees duab, xws li magnetic resonance imaging thiab radionuclide imaging, los txhim kho qhov tseeb thiab rhiab heev.
