Iwo matatu anonyanya kufarirwa marudzi emaprobes (anonziwo ultrasonic transducers) ane mutsara, convex, uye phased array.Iyo mutsara padyo-munda resolution yakanaka uye inogona kushandiswa pakuongorora tsinga yeropa.Iyo convex surface inokodzera kuongororwa kwakadzama, iyo inogona kushandiswa pakuongorora dumbu uye zvichingodaro.Iyo yakakamurwa array ine diki tsoka uye yakaderera frequency, iyo inogona kushandiswa kuongororwa kwemoyo, nezvimwe.
Linear sensor
Iwo piezoelectric makristasi akarongwa zvine mutsetse, chimiro chedanda chine rectangular, uye padhuze-munda resolution yakanaka.
Chechipiri, kuwanda uye mashandisirwo emitsara transducers zvinoenderana nekuti chigadzirwa chinoshandiswa 2D kana 3D imaging.Linear transducer anoshandiswa ku 2D imaging akanangana ne 2.5Mhz - 12Mhz.
Iwe unogona kushandisa sensor iyi kune akasiyana maapplication akadai: kuongororwa kwevascular, venipuncture, vascular visualization, thoracic, thyroid, tendon, arthogenic, intraoperative, laparoscopic, photoacoustic imaging, ultrasound velocity shanduko yekufungidzira.
Linear transducers ye 3D imaging ine pakati frequency ye7.5Mhz - 11Mhz.
Unogona kushandisa shanduro iyi: chipfuva, thyroid, vascular application carotid.
Convex sensor
Convex probe image resolution inodzikira sezvo kudzika kunowedzera, uye kuwanda kwayo uye mashandisirwo zvinoenderana nekuti chigadzirwa chinoshandiswa 2D kana 3D imaging.
Semuenzaniso, maconvex transducer e2D imaging ane pakati frequency ye2.5MHz - 7.5MHz.Unogona kuishandisa kune: bvunzo dzedumbu, transvaginal uye transrectal bvunzo, organ kuongororwa.
Iyo convex transducer ye 3D imaging ine nzvimbo yakakura yekuona uye yepakati frequency ye 3.5MHz-6.5MHz.Unogona kuishandisa pabvunzo dzedumbu.
Phased Array Sensor
Iyi transducer, yakatumidzwa mushure mekurongedzerwa kwepiezoelectric crystals, inonzi phased array, ndiyo inonyanya kushandiswa kristaro.Iyo danda nzvimbo yakamanikana asi inowedzera zvichienderana neiyo frequency application.Uyezve, chimiro chedanda chinoda kuita katatu uye sarudzo yepedyo-munda haina kunaka.
Tinogona kuishandisa ku: bvunzo dzemoyo, kusanganisira transesophageal bvunzo, bvunzo dzedumbu, bvunzo dzehuropi.
