Mitundu itatu yodziwika bwino ya ma probe (omwe amatchedwanso ma ultrasonic transducers) ndi ozungulira, owoneka bwino, komanso otsatizana.Liniya wapafupi ndi munda ndi wabwino ndipo angagwiritsidwe ntchito powunika mitsempha yamagazi.Mawonekedwe a convex amathandizira kufufuza mozama, komwe kungagwiritsidwe ntchito pofufuza m'mimba ndi zina zotero.Gulu lokhazikika limakhala ndi phazi laling'ono komanso ma frequency otsika, omwe angagwiritsidwe ntchito poyesa mtima, ndi zina zambiri.
Linear sensor
Makatani a piezoelectric amakonzedwa motsatira mzere, mawonekedwe a mtengowo ndi amakona anayi, ndipo mawonekedwe apafupi ndi abwino.
Chachiwiri, mafupipafupi ndi kugwiritsa ntchito ma transducers amzere zimatengera ngati mankhwalawa amagwiritsidwa ntchito pazithunzi za 2D kapena 3D.Ma Linear transducer omwe amagwiritsidwa ntchito pazithunzi za 2D ali pakati pa 2.5Mhz - 12Mhz.
Mutha kugwiritsa ntchito sensayi pazinthu zosiyanasiyana monga: kuwunika kwa mitsempha, venipuncture, kuwonetsa mitsempha, thoracic, chithokomiro, tendon, arthogenic, intraoperative, laparoscopic, imaging photoacoustic, ultrasound velocity change imaging.
Ma Linear transducer a kujambula kwa 3D amakhala ndi ma frequency apakati a 7.5Mhz - 11Mhz.
Mukhoza kugwiritsa ntchito Converter: chifuwa, chithokomiro, mtima ntchito carotid.
Sensor ya convex
Kusintha kwa chithunzi cha convex probe kumachepera pamene kuya kukuchulukirachulukira, ndipo pafupipafupi komanso kugwiritsa ntchito kwake kumadalira ngati chinthucho chikugwiritsidwa ntchito pazithunzi za 2D kapena 3D.
Mwachitsanzo, ma transducer a ma convex amajambula a 2D amakhala ndi ma frequency apakati a 2.5MHz - 7.5MHz.Mutha kugwiritsa ntchito: mayeso am'mimba, mayeso a transvaginal ndi transrectal, kuzindikira kwa ziwalo.
Transducer ya ma convex ya kujambula kwa 3D ili ndi malo ambiri owonera komanso ma frequency apakati a 3.5MHz-6.5MHz.Mutha kugwiritsa ntchito mayeso a m'mimba.
Sensor ya Phased Array
Transducer iyi, yotchulidwa potengera makonzedwe a piezoelectric crystals, yotchedwa phased array, ndiyo kristalo yomwe imagwiritsidwa ntchito kwambiri.Phindu lake ndi lopapatiza koma limakula molingana ndi kuchuluka kwa ntchito.Kuphatikiza apo, mawonekedwe a mtengowo amakhala pafupifupi katatu ndipo mawonekedwe apafupi ndi gawo losavuta.
Titha kugwiritsa ntchito: mayeso amtima, kuphatikiza mayeso a transesophageal, mayeso amimba, mayeso aubongo.
