NDOKUSARUDZA SEI TRANSDUCER YAKODZERA YE ULTRASOUND SCANNER?

Kubudirira kwescanning devicezvakanyanya zvinoenderana neiyo ultrasound sensors yakaiswa mairi.Nhamba yavo mune imwe scanning mudziyo inogona kusvika kusvika 30 zvidimbu.Ndeapi ma sensors, ndeapi uye maitiro ekuasarudza nemazvo - ngatitarisei zvakanyanya.

MATYPES E ULTRASONIC SENSOR:

• linear probes anoshandiswa pakuongorora kuongororwa kwezvimiro zvisina kudzika uye nhengo.Kuwanda kwavanoita 7.5 MHz;
• convex probes anoshandiswa kuongorora zvakadzika matishu uye nhengo.Iyo frequency iyo sensors yakadaro inoshanda iri mukati me2.5-5 MHz;
• microconvex sensors - chiyero chekushandiswa kwavo uye kuwanda kwaanoshanda nawo kwakafanana nemhando mbiri dzekutanga;
• intracavitary sensors - inoshandiswa kune transvaginal uye zvimwe intracavitary zvidzidzo.Yavo yekuongorora frequency ndeye 5 MHz, dzimwe nguva yakakwirira;
• biplane sensors anoshandiswa zvakanyanya kune transvaginal diagnostics;
• intraoperative sensors (convex, neurosurgical uye laparoscopic) inoshandiswa panguva yekuvhiya;
• invasive sensors - inoshandiswa kuongorora tsinga dzeropa;
• ophthalmic sensors (convex kana sectoral) - inoshandiswa mukudzidza kweziso reziso.Vanoshanda pane frequency ye10 MHz kana kupfuura.

ZVINHU ZVINHU ZVOKUSARUDZA MASENSI KUTI ULTRASOUND SCANNER

Kune marudzi akawanda akasiyana-siyanaultrasonic sensors.Vanosarudzwa zvichienderana nekushandiswa.Zera renyaya inotariswawo.Semuenzaniso, 3.5 MHz sensors inokodzera vanhu vakuru, uye kuvarwere vaduku, masensa emhando imwechete anoshandiswa, asi nepamusoro-soro yekushanda - kubva ku5 MHz.Kuti uwane zvakadzama kuongororwa kwepathologies yehuropi hwevachangobva kuberekwa, masectoral sensors anoshanda panguva yakawanda ye5 MHz, kana yepamusoro-frequency microconvex sensors anoshandiswa.

Kuti udzidze nhengo dzemukati dziri pakadzika, ma ultrasound sensors anoshandiswa, achishanda pane frequency ye 2.5 MHz, uye kune zvimiro zvisina kudzika, iyo frequency inofanira kunge inosvika 7.5 MHz.

Kuongororwa kwemoyo kunoitwa pachishandiswa ma ultrasonic sensors akashongedzerwa neantenna yakaganhurwa uye anoshanda pafrequency inosvika 5 MHz.Kuongorora moyo, masensa anoshandiswa anopinzwa nepagurokuro.

Kuongorora kwehuropi uye transcranial bvunzo kunoitwa uchishandisa masensa, iyo inoshanda frequency iyo 2 MHz.Ultrasound sensors inoshandiswa kuongorora maxillary sinuses, ine frequency yakakwirira - kusvika ku3 MHz.
