Peb hom kev sojntsuam feem ntau (tseem hu ua ultrasonic transducers) yog linear, convex, thiab phased array.Qhov kev daws teeb meem nyob ze ntawm qhov chaw yog qhov zoo thiab tuaj yeem siv rau kev kuaj ntshav.Convex nto yog qhov zoo rau kev kuaj xyuas qhov tob, uas tuaj yeem siv rau kev kuaj mob plab thiab lwm yam.Phaseed array muaj qhov me me hneev taw thiab qis zaus, uas tuaj yeem siv rau kev kuaj mob plawv, thiab lwm yam.
Linear sensor
Lub piezoelectric crystals yog teem linearly, lub beam duab yog rectangular, thiab nyob ze-tsav daws teeb meem yog zoo.
Qhov thib ob, qhov zaus thiab daim ntawv thov ntawm linear transducers nyob ntawm seb cov khoom siv rau 2D lossis 3D duab.Linear transducers siv rau 2D duab yog nyob nruab nrab ntawm 2.5Mhz - 12Mhz.
Koj tuaj yeem siv qhov ntsuas no rau ntau yam kev siv xws li: vascular kuaj, venipuncture, vascular visualization, thoracic, thyroid, tendon, arthogenic, intraoperative, laparoscopic, photoacoustic imaging, ultrasound velocity hloov imaging.
Linear transducers rau 3D duab muaj qhov chaw nruab nrab ntawm 7.5Mhz - 11Mhz.
Koj tuaj yeem siv qhov hloov pauv no: hauv siab, thyroid, vascular daim ntawv thov carotid.
Convex sensor
Convex sojntsuam duab daws teeb meem txo qis thaum qhov tob nce, thiab nws zaus thiab daim ntawv thov nyob ntawm seb cov khoom siv rau 2D lossis 3D duab.
Piv txwv li, convex transducers rau 2D imaging muaj qhov nruab nrab zaus ntawm 2.5MHz - 7.5MHz.Koj tuaj yeem siv nws rau: kev kuaj mob plab, kev kuaj ntshav thiab transrectal, kuaj lub cev.
Lub convex transducer rau 3D duab muaj qhov dav ntawm qhov pom thiab qhov chaw nruab nrab ntawm 3.5MHz-6.5MHz.Koj tuaj yeem siv nws rau kev kuaj mob plab.
Phaseed Array Sensor
Qhov no transducer, muaj npe tom qab kev teeb tsa ntawm piezoelectric crystals, hu ua phased array, yog cov siv lead ua feem ntau.Nws qhov chaw beam yog nqaim tab sis nthuav dav raws li daim ntawv thov zaus.Tsis tas li ntawd, cov kab teeb pom kev zoo yuav luag daim duab peb sab thiab qhov kev daws teeb meem nyob ze yog qhov tsis zoo.
Peb tuaj yeem siv nws rau: kev kuaj mob plawv, nrog rau kev kuaj mob transesophageal, kuaj mob plab, kuaj mob hlwb.
