Isu tese tinoziva kuti iyo ultrasonic diagnostic chiridzwa inogadzira chiitiko ultrasonic mafungu (kutumira mafungu) uye inogamuchira inoratidzira ultrasonic waves (echo waves) kuburikidza neprobe.Icho chikamu chakakosha chemidziyo yekuongorora, semeso e-B-ultrasound muchina, uye zvakare yakabatana nemuviri wemunhu uye nemidziyo.pakati.
Basa reiyo ultrasound probe nderekushandura masaini emagetsi kuita ma ultrasonic masaini kana zvinopesana.Iyo probe inogona kutumira uye kugamuchira ultrasound, uye kuita electro-acoustic uye chiratidzo chekushandura.Inogona kushandura chiratidzo chemagetsi chinotumirwa nemugadziri kuita yakakwira-frequency oscillating ultrasonic chiratidzo, uye zvakare inogona kushandura iyo ultrasonic chiratidzo inoratidzwa kumashure kubva kumatishu uye nhengo kuita masaini emagetsi.pamonitor yekombuta inotambira.Iyo ultrasonic probe inogadzirwa uchishandisa iyi inoshanda musimboti.Kazhinji, inoshandura chiratidzo chemagetsi chinobudiswa ne ultrasound kuita mafungu e-high-frequency sound uye inotumira kuburikidza nemuviri wemunhu, uye inoshandura chiratidzo chinoratidzwa muchiratidzo chemagetsi uye chinochiratidzira pane chidzitiro chekugamuchira, sezvinongoita whale.Iwo ma ultrasonic frequencies anobuditswa munyanza akafanana nezviremwaremwa zvinotonga chinhambwe chezvinhu nekuratidzwa kwemasaisai eruzha usiku.
Iyo wafer mukati me probe inogona kuburitsa elastic deformation pasi pesimba-panyika, nekudaro ichigadzira ultrasonic inzwi mafungu;pane zvinopesana, kana mafungu e ultrasonic anonzwika achipfuura nepawafer, anogona zvakare kukonzera elastic deformation, iyo inokonzeresa shanduko yevoltage, uye pakupedzisira ichipfuura kuburikidza neiyo chiratidzo chekugadzirisa bhodhi inogadzirisa inopindirana chiratidzo chemagetsi shanduko kupedzisa kutariswa kwemufananidzo wechinhu chaonekwa. .Iyi nzira yekugadzira inonzi piezoelectric effect (yakanaka uye inverse piezoelectric effect).
Iko kushandiswa kweakajairika ultrasound probes mumadhipatimendi akasiyana:
Kushandiswa kweconvex array probe (3.5MHz) mune obstetrics uye gynecology uye hepatobiliary, pancreas, spleen uye itsvo.
Line array probe (3.5MHz) yekushandiswa kwetsinga dzeropa uye nhengo diki
