MUNGASANKHA BWANJI TRANSDUCER YOYENERA PA ULTRASOUND SCANNER?

The dzuwa lasikani chipangizomakamaka zimadalira masensa a ultrasound omwe amaikidwa mmenemo.Chiwerengero chawo mu chipangizo chimodzi chojambulira chimatha kufikira zidutswa 30.Kodi masensa ndi chiyani, ndi chiyani komanso momwe angasankhire molondola - tiyeni tiwone mwatsatanetsatane.

MITUNDU YA MA ULTRASONIC SENSOR:

• ma liniya probes amagwiritsidwa ntchito pofufuza matenda a ziwalo zozama ndi ziwalo.Mafupipafupi omwe amagwira ntchito ndi 7.5 MHz;
• ma convex probes amagwiritsidwa ntchito pozindikira minofu ndi ziwalo zomwe zili mkati.Mafupipafupi omwe masensa oterewa amagwira ntchito mkati mwa 2.5-5 MHz;
• masensa a microconvex - kukula kwa ntchito yawo ndi mafupipafupi omwe amagwira ntchito mofanana ndi mitundu iwiri yoyamba;
• masensa intracavitary - ntchito transvaginal ndi maphunziro ena intracavitary.Kusanthula kwawo pafupipafupi ndi 5 MHz, nthawi zina kumtunda;
• masensa biplane ntchito makamaka transvaginal diagnostics;
• ma intraoperative sensors (convex, neurosurgical and laparoscopic) amagwiritsidwa ntchito popanga opaleshoni;
• masensa invasive - ntchito kuzindikira mitsempha ya magazi;
• ophthalmic sensors (convex kapena sectoral) - amagwiritsidwa ntchito pophunzira diso.Iwo amagwira ntchito pafupipafupi 10 MHz kapena kuposa.

MFUNDO YOSANKHA ZINTHU ZONSE ZA ULTRASOUND SCANNER

Pali mitundu yambiri yosiyanasiyanaultrasonic sensors.Iwo amasankhidwa malinga ndi ntchito.Zaka za phunzirolo zimaganiziridwanso.Mwachitsanzo, masensa a 3.5 MHz ndi oyenera kwa akuluakulu, ndipo kwa odwala ang'onoang'ono, masensa amtundu womwewo amagwiritsidwa ntchito, koma ndi maulendo apamwamba - kuchokera ku 5 MHz.Kuti muzindikire mwatsatanetsatane ma pathologies a muubongo wa ana akhanda, masensa am'magulu omwe amagwira ntchito pafupipafupi 5 MHz, kapena masensa apamwamba kwambiri a microconvex amagwiritsidwa ntchito.

Kuphunzira ziwalo zamkati zomwe zili zakuya, masensa a ultrasound amagwiritsidwa ntchito, omwe amagwira ntchito pafupipafupi 2.5 MHz, ndi zomangamanga zosaya, mafupipafupi ayenera kukhala osachepera 7.5 MHz.

Mayeso a mtima amachitidwa pogwiritsa ntchito masensa akupanga omwe ali ndi mlongoti wokhazikika ndipo amagwira ntchito pafupipafupi mpaka 5 MHz.Kuti azindikire mtima, ma sensa amagwiritsidwa ntchito omwe amalowetsedwa kudzera kukhosi.

Kafukufuku waubongo ndi mayeso a transcranial amachitidwa pogwiritsa ntchito masensa, ma frequency opangira omwe ndi 2 MHz.Masensa a Ultrasound amagwiritsidwa ntchito pofufuza maxillary sinuses, ndi ma frequency apamwamba - mpaka 3 MHz.
