Sonke siyazi ukuthi ithuluzi lokuxilonga i-ultrasonic likhiqiza amagagasi e-ultrasonic (amagagasi adlulisayo) futhi lithola amaza abonakalayo e-ultrasonic (amaza e-echo) ngophenyo.Iyingxenye ebalulekile yemishini yokuxilonga, njengamehlo omshini we-B-ultrasound, futhi ixhunywe nomzimba womuntu kanye nemishini.okuphakathi.
Umsebenzi we-ultrasound probe ukuguqula amasignali kagesi abe amasignali e-ultrasonic noma ngokuphambene nalokho.I-probe ingadlulisela futhi yamukele i-ultrasound, futhi yenze i-electro-acoustic kanye nokuguqulwa kwesignali.Ingakwazi ukuguqula isignali kagesi ethunyelwe umsingathi ibe isignali ye-ultrasonic oscillating ephezulu, futhi ingaphinda iguqule isignali ye-ultrasonic eboniswa emuva isuka ezicutshini nasezithweni ibe amasignali kagesi.kumonitha yekhompuyutha yokusingatha.I-probe ye-ultrasonic yenziwa kusetshenziswa lesi simiso sokusebenza.Ngokuvamile, iguqula isignali kagesi ekhishwa i-ultrasound ibe amaza omsindo wefrikhwensi ephezulu futhi iyidlulisele emzimbeni womuntu, bese iguqula isignali ebonisiwe ibe isignali kagesi futhi iyibonise esikrinini somsingathi, njengomkhomo.Izandiso ze-ultrasonic eziphuma olwandle zifana namalulwane ahlulela ibanga lezinto ngokubonakala kwamaza omsindo ebusuku.
I-wafer ngaphakathi kwe-probe ingakhiqiza ukuguquguquka okunwebekayo ngaphansi kwesimo sokusebenza kwamandla, ngaleyo ndlela ikhiqize amaza omsindo we-ultrasonic;ngokuphambene nalokho, lapho amaza omsindo we-ultrasonic edlula esilucwecweni, angabangela nokuguquguquka okunwebekayo, okubangela ukushintsha kwamandla kagesi, futhi ekugcineni kudlule Ibhodi lokucubungula isignali licubungula izinguquko zesignali kagesi ezihambisanayo ukuze kuqedelwe ukutholwa kwesithombe sento etholiwe. .Le nqubo yokucubungula ibizwa ngokuthi umphumela we-piezoelectric (umphumela we-piezoelectric omuhle futhi ophambene).
Ukusetshenziswa kwe-ultrasound probes ezivamile eminyangweni ehlukahlukene:
Ukusetshenziswa kwe-convex array probe (3.5MHz) ku-obstetrics kanye ne-gynecology kanye ne-hepatobiliary, amanyikwe, ubende nezinso
I-line array probe (3.5MHz) yokusetshenziswa kwemithambo yegazi nezitho ezincane
