UNGAYIKHETHA KANJANI I-TRANSDUCER EFANELE YE-ULTRASOUND SCANNER?

Ukusebenza kahle kwe-idivayisi yokuskenakuncike kakhulu kuzinzwa ze-ultrasound ezifakwe kuyo.Inombolo yabo kudivayisi eyodwa yokuskena ingafinyelela izingcezu ezingu-30.Yiziphi izinzwa, zenzelweni nokuthi kukhethwa kanjani ngendlela efanele – ake sibhekisise.

IZINHLOBO ZEZInzwa ze-ULTRASONIC:

• ama-linear probe asetshenziselwa ukuhlolwa kokuxilonga kwezakhiwo nezitho ezingajulile.Imvamisa abasebenza kuyo ingu-7.5 MHz;
• Ama-convex probe asetshenziselwa ukuxilonga izicubu nezitho ezijule.Imvamisa lapho izinzwa ezinjalo zisebenza khona ngaphakathi kwe-2.5-5 MHz;
• izinzwa ze-microconvex - ububanzi bokusetshenziswa kwazo kanye nemvamisa lapho zisebenza khona ziyefana nezinhlobo ezimbili zokuqala;
• izinzwa ze-intracavitary - ezisetshenziselwa izifundo ze-transvaginal nezinye ze-intracavitary.Imvamisa yabo yokuskena i-5 MHz, kwesinye isikhathi iphakeme;
• izinzwa ze-biplane zisetshenziselwa ikakhulukazi ukuxilongwa kwe-transvaginal;
• Izinzwa ze-intraoperative (convex, neurosurgical kanye ne-laparoscopic) zisetshenziswa ngesikhathi sokuhlinzwa;
• izinzwa ezihlaselayo - ezisetshenziselwa ukuxilonga imithambo yegazi;
• izinzwa ze-ophthalmic (i-convex noma i-sectoral) - ezisetshenziswa ekutadisheni kwe-eyeball.Basebenza ngemvamisa ye-10 MHz noma ngaphezulu.

ISIMISO SOKUKHETHA IZInzwa ZE-ULTRASOUND SCANN

Kunezinhlobo eziningi ezihlukahlukeneizinzwa ze-ultrasonic.Akhethwa kuye ngohlelo lokusebenza.Iminyaka yesifundo nayo iyabhekwa.Isibonelo, izinzwa ze-3.5 MHz zifanelekile kubantu abadala, futhi ezigulini ezincane, izinzwa zohlobo olufanayo zisetshenziswa, kodwa ngemvamisa yokusebenza ephezulu - kusuka ku-5 MHz.Ukuze uthole ukuxilongwa okuningiliziwe kwe-pathologies yobuchopho bezingane ezisanda kuzalwa, kusetshenziswa izinzwa zemikhakha ezisebenza ngemvamisa ye-5 MHz, noma izinzwa ze-microconvex ze-high-frequency.

Ukuze ufunde izitho zangaphakathi ezijulile, kusetshenziswa izinzwa ze-ultrasound, ezisebenza ngemvamisa ye-2.5 MHz, futhi ezakhiweni ezingajulile, imvamisa kufanele okungenani ibe ngu-7.5 MHz.

Ukuhlolwa kwenhliziyo kwenziwa kusetshenziswa izinzwa ze-ultrasonic ezifakwe i-antenna enezigaba futhi ezisebenza ngemvamisa efika ku-5 MHz.Ukuze kuhlolwe inhliziyo, kusetshenziswa izinzwa ezishuthekwa ngomminzo.

Ucwaningo lobuchopho kanye nokuhlolwa kwe-transcranial kwenziwa kusetshenziswa izinzwa, imvamisa yokusebenza okuyi-2 MHz.Izinzwa ze-Ultrasound zisetshenziselwa ukuhlola ama-maxillary sinuses, nemvamisa ephezulu - kufika ku-3 MHz.
