ʻO nā ʻano probes maʻamau ʻekolu (i kapa ʻia hoʻi nā transducers ultrasonic) he laina laina, convex, a me nā papa hana.Maikaʻi ka hoʻonā ʻana o ka laina kokoke i ke kahua a hiki ke hoʻohana ʻia no ka nānā ʻana i nā moku koko.Hiki i ka ʻili convex ke hoʻokolokolo hohonu, hiki ke hoʻohana ʻia no ka nānā ʻana o ka ʻōpū a pēlā aku.He wahi wāwae liʻiliʻi a me ka haʻahaʻa haʻahaʻa o ka array phased, hiki ke hoʻohana ʻia no ka hoʻokolokolo cardiac, etc.
ʻIke laina laina
Hoʻonohonoho ʻia nā kristal piezoelectric i ka laina, ʻehā ke ʻano o ka beam, a maikaʻi ka hoʻonā kokoke.
ʻO ka lua, ʻo ke alapine a me ka hoʻohana ʻana o nā transducers linear e pili ana i ka hoʻohana ʻana o ka huahana no 2D a i ʻole 3D imaging.ʻO nā transducers laina i hoʻohana ʻia no ke kiʻi kiʻi 2D i waena o 2.5Mhz - 12Mhz.
Hiki iā ʻoe ke hoʻohana i kēia sensor no nā noi like ʻole: ka nānā ʻana i ka vascular, venipuncture, vascular visualization, thoracic, thyroid, tendon, arthogenic, intraoperative, laparoscopic, photoacoustic imaging, ultrasound velocity change imaging.
ʻO nā transducers laina no ke kiʻi kiʻi 3D he kikowaena waena o 7.5Mhz - 11Mhz.
Hiki iā ʻoe ke hoʻohana i kēia mea hoʻololi: umauma, thyroid, vascular application carotid.
Mea ʻikena convex
Ke emi nei ka hoʻonā kiʻi convex probe i ka piʻi ʻana o ka hohonu, a hilinaʻi kona alapine a me ka hoʻohana ʻana inā hoʻohana ʻia ka huahana no ke kiʻi 2D a i ʻole 3D.
No ka laʻana, ʻo nā transducers convex no ke kiʻi kiʻi 2D he kikowaena waena o 2.5MHz - 7.5MHz.Hiki iā ʻoe ke hoʻohana iā ia no: nā hoʻokolohua ʻōpū, nā hoʻokolohua transvaginal a me nā transrectal, ʻike kino.
ʻO ka transducer convex no ke kiʻi kiʻi 3D he ākea ākea o ka nānā a me ke alapine waena o 3.5MHz-6.5MHz.Hiki iā ʻoe ke hoʻohana iā ia no nā hoʻokolohua ʻōpū.
Pūnaehana Array Phased
ʻO kēia transducer, i kapa ʻia ma hope o ka hoʻonohonoho ʻana o nā kristal piezoelectric, i kapa ʻia he array phased, ʻo ia ka kristal i hoʻohana pinepine ʻia.He haiki kona wahi kukuna akā hoʻonui ʻia e like me ke alapine noi.Eia kekahi, ʻaneʻane triangular ke ʻano o ka lāʻau a maikaʻi ʻole ka hoʻonā kokoke i ke kahua.
Hiki iā mākou ke hoʻohana iā ia no: nā hoʻokolohua naʻau, me nā hoʻokolohua transesophageal, nā hoʻokolohua ʻōpū, nā hoʻokolohua lolo.
