Probe classification uye probe frequency kusarudzwa kweB ultrasound muchina

Ultrasonic attenuation mumuviri wemunhu inoenderana neiyo ultrasonic frequency.Iyo yakakwirira iyo probe frequency yemuchina weB-ultrasound, kusimba kwekudzikisira, kuderera kwekupinda, uye kukwira kwekugadzirisa.High frequency probes yakashandiswa mukuongorora nhengo dzepamusoro.Low frequency probe ine simba rekupinda rinoshandiswa kuongorora yakadzika viscera.

B ultrasonic muchina probe classification

2. Convex array probe: probe surface is convex, nzvimbo yekubata idiki, munda uri padyo idiki, munda uri kure wakakura, weimaging wakaita sefan, uye unoshandiswa zvakanyanya mudumbu nemapapu. .
3. Linear array probe: iyo probe surface yakadzikama, nzvimbo yekuonana yakakura, nzvimbo yepedyo yemunda yakakura, nzvimbo iri kure idiki, iyo yekufungidzira ine rectangular, yakakodzera kumidziyo yeropa uye nhengo diki dzepamusoro.
Chekupedzisira, iyo probe yemuchina weB ultrasound ndiyo chikamu chepakati yemuchina wese weultrasonic.Chinhu chakanyatsojeka uye chakapfava.Isu tinofanirwa kutarisisa kune probe mukuita kwekushandisa, uye tiite zvinyoro.

B ultrasonic probe frequency uye mhando inoshandiswa munzvimbo dzakasiyana dzekuongorora

1, madziro echipfuva, pleura nemapapu madiki maronda madiki: 7-7.5mhz linear array probe kana convex array probe
2, Chiropa ultrasound kuongororwa:

① Convex array probe kana linear array probe

② Vakuru: 3.5-5.0mhz, vana kana vakuru vakaonda: 5.0-8.0mhz, vakafuta: 2.5mhz

3, Gastrointestinal ultrasound kuongororwa:

① Convex array probe inoshandiswa pakuongorora dumbu.Iyo frequency ndeye 3.5-10.0mhz, uye 3.5-5.0mhz ndiyo inonyanya kushandiswa.

② Intraoperative ultrasound: 5.0-12.0mhz parallel array probe

③ Endoscopic ultrasound: 7.5-20mhz

④ Rectal ultrasound: 5.0-10.0mhz

⑤ Ultrasound-inotungamirwa puncture probe: 3.5-4.0mhz, micro-convex probe uye diki-nhanho dhizaini yakarongeka ine puncture guide frame
4, itsvo ultrasound: kurongwa kwechikamu, convex array kana linear array probe, 2.5-7.0mhz;Vana vanogona kusarudza ma frequency epamusoro
5, retroperitoneal ultrasound kuongororwa: convex array probe: 3.5-5.0mhz, munhu mutete, aripo 7.0-10.0 high frequency probe
6, adrenal ultrasound: yakasarudzika convex array probe, 3.5mhz kana 5.0-8.0mhz
