Ihame ryubuvuzi ultrasound

Ubuvuzi bwa ultrasounde yubuvuzi nigice cyingenzi cyibikoresho byubuvuzi ultrasound. Ihame ryayo nyamukuru nugukoresha ikwirakwizwa no kwerekana ibimenyetso biranga imiraba ya ultrasonic mumyanya yabantu kugirango ubone amashusho binyuze mumikorere yohereza no kwakira iperereza kugirango ugere kubuvuzi no kuvurwa.

Amahame ya ultrasound yubuvuzi arashobora kugabanywamo ibice bikurikira:

1. Ukoresheje iyi ngaruka, ibikoresho bya piezoelectric birashobora kunyeganyezwa binyuze mumashanyarazi ashimishije, bityo bikabyara imiraba ya ultrasonic.

2. Iyo ikintu gishimishije n'umuriro w'amashanyarazi, kinyeganyeza mu buryo bwa mashini, kibyara impiswi ya ultrasonic. Imiterere ya pulse ninshuro zo kunyeganyega biterwa nubushakashatsi bwa probe na moteri ya voltage.

3. Iyo ultrasound waves inyuze mumyenda, iragaragazwa kandi ikanyanyagizwa mugice cyo kwakira iperereza. Ikintu cyakira gihindura imashini yinyeganyeza mukimenyetso cyo kwishyuza, hanyuma igahinduka mumashusho binyuze mukuzunguruka ibimenyetso.

4. Ijwi ryijwi ryerekana gukwirakwiza ingufu za ultrasonic waves ikwirakwiza hagati. Ubuvuzi bwa ultrasound yubuvuzi bukoresha tekinoroji yibanze kugirango itezimbere ubushobozi bwokwibanda kumajwi, bikavamo amashusho asobanutse.

5. Ingaruka ya Doppler: Ubushakashatsi bwa ultrasound yubuvuzi burashobora kandi gukoresha ingaruka ya Doppler kugirango bapime umuvuduko nicyerekezo cyamazi. Iyo ultrasonic waves ihuye nigikorwa cyamazi, ihinduka ryinshuro riba, rijyanye numuvuduko wamazi. Mugupima ubunini nicyerekezo cyimihindagurikire yumurongo, amakuru ajyanye nigikorwa cyamazi arashobora kuboneka.
