Sonke siyazi ukuba isixhobo sokuxilonga se-ultrasonic sivelisa amaza e-ultrasonic (amaza okuhambisa) kwaye sifumana amaza e-ultrasonic abonakalisiweyo (amaza e-echo) ngokusebenzisa i-probe.Iyinxalenye ebalulekileyo yezixhobo zokuxilonga, njengamehlo omatshini we-B-ultrasound, kwaye idibene nomzimba womntu kunye nezixhobo.phakathi.
Umsebenzi weprobe ye-ultrasound kukuguqula izibonakaliso zombane kwiimpawu ze-ultrasonic okanye ngokuphambene noko.I-probe inokudlulisa kwaye ifumane i-ultrasound, kwaye yenza i-electro-acoustic kunye nokuguqulwa kwesignali.Inokuguqula umqondiso wombane othunyelwe ngumninimzi kwi-high-frequency oscillating signal ye-ultrasonic, kwaye inokuguqula isignali ye-ultrasonic ebonakaliswe ngasemva ukusuka kwizicubu kunye nezitho zibe yimiqondiso yombane.kwimonitha yekhompyuter yenginginya.Iprobe ye-ultrasonic yenziwe ngokusebenzisa lo mgaqo wokusebenza.Ngokubanzi, iguqula isignali yombane ekhutshwe yi-ultrasound ibe ngamaza esandi esiphakamileyo kwaye idlulise ngomzimba womntu, kwaye emva koko iguqule umqondiso obonakalisiweyo ibe ngumqondiso wombane kwaye uyibonise kwisikrini somkhosi, njengomnenga.Izandi ze-ultrasonic ezikhutshwa elwandle zifana namalulwane ajonga umgama wezinto ngokubonakala kwamaza esandi ebusuku.
I-wafer ngaphakathi kwe-probe inokuvelisa i-elastic deformation phantsi kwe-state-on state, ngaloo ndlela ivelisa amaza omsindo we-ultrasonic;ngokuchaseneyo, xa amaza esandi se-ultrasonic edlula kwi-wafer, anokubangela ukuba i-elastic deformation, leyo ibangele utshintsho lwe-voltage, kwaye ekugqibeleni idlule kwibhodi yokucwangcisa umqondiso ohambelana notshintsho lwesignali yombane ukugqiba ukubonwa komfanekiso wento ebhaqiweyo. .Le nkqubo yokucubungula ibizwa ngokuba yi-piezoelectric effect (isiphumo esihle kunye ne-inverse piezoelectric effect).
Ukusetyenziswa kweeprobes eziqhelekileyo ze-ultrasound kumasebe ahlukeneyo:
Ukusetyenziswa kwe-convex array probe (3.5MHz) kwi-obstetrics kunye ne-gynecology kunye ne-hepatobiliary, i-pancreas, i-spleen kunye nezintso.
Uluhlu lweprobe (3.5MHz) yokusetyenziswa kwemithambo yegazi kunye namalungu amancinci
